Warning Signs of Cardiac Arrest

Sudden cardiac arrest is frightening. But it’s a little less scary if you know that it’s really not that sudden. A new study found that about half of cardiac arrest patients had telltale warning signs for a month beforehand. But most people ignored them. Here are four signs that could signal sudden cardiac arrest and why you shouldn’t ignore them.

10 Facts about A [little] Fib that May Surprise You

Atrial fibrillation, also called AF or AFib, is the most common type of heart rhythm disorder. People with this condition are at higher risk for serious medical complications, such as dementia, heart failure, stroke, or even death. Too many of those affected by the condition don’t realize that they have it, and many who have it don’t realize the seriousness of the affliction. All too often, healthcare providers may also minimize the effects of the condition.

September is Atrial Fibrillation Awareness Month, designated to help patients and healthcare providers learn more about this complex condition. In addition to stroke prevention, additional know-how can improve the overall wellness of those suffering from AFib. Often, those with AFib have a lower quality of life than those who have suffered a heart attack. And, unfortunately, some healthcare providers may not know about treatment options that can essentially put a stop to the condition.

For those who have AFib, seeking information about the ailment and  finding early treatment are imperative. The longer someone has AFib, the more likely they will convert from intermittent AFib to enduring it all the time, making it much more difficult to stop or cure.

What is atrial fibrillation?

Atrial fibrillation (also called AFib or AF) is a quivering or irregular heartbeat (arrhythmia) that can lead to blood clots, stroke, heart failure and other heart-related complications.  A racing, pounding heartbeat that happens for no apparent reason should not be ignored, especially when other symptoms are also present — like shortness of breath with light physical activity or lightheadedness, dizziness, or unusual fatigue. AFib occurs when the heart muscles fail to contract in a strong, rhythmic way. When a heart is in AFib, it may not be pumping enough oxygen-rich blood out to the body.

Why is AFib associated with a five-times-greater risk for stroke?

When the heart is in AFib, the blood can become static and can be left pooling inside the heart. When blood pools, a clot can form. When a clot is pumped out of the heart, it can get lodged in the arteries which may cause a stroke. Blocked arteries prevent the tissue on the other side from getting oxygen-rich blood, and without oxygen the tissue dies.

Any person who has AFib needs to evaluate stroke risks and determine with a healthcare provider what must be done to lower the risks. Studies show that many people with AFib who need risk-lowering treatments are not getting them. Learn more about stroke risks with the CHA2DS2–VASc tool.

If I don’t have these symptoms, should I be concerned?

There are people who have atrial fibrillation that do not experience noticeable symptoms. These people may be diagnosed at a regular check-up or their AFib may be discovered when a healthcare provider listens to their heart for some other reason.

However, people who have AFib with no symptoms still have a five-times-greater risk of stroke. Everyone needs to receive regular medical check-ups to help keep risks low and live a long and healthy life.  Many may experience one or more of the following symptoms:

  • General fatigue
  • Rapid and irregular heartbeat
  • Fluttering or “thumping” in the chest
  • Dizziness
  • Shortness of breath and anxiety
  • Weakness
  • Faintness or confusion
  • Fatigue when exercising
  • Sweating
  • Chest pain or pressure

Are there different types of AFib?

The symptoms are generally the same; however, the duration of the AFib and underlying reasons for the condition help medical practitioners classify the type of AFib problems.

  • Paroxysmal fibrillation is when the heart returns to a normal rhythm on its own, or with intervention, within 7 days of its start. People who have this type of AFib may have episodes only a few times a year or their symptoms may occur every day. These symptoms are very unpredictable and often can turn into a permanent form of atrial fibrillation.
  • Persistent AFib is defined as an irregular rhythm that lasts for longer than 7 days. This type of atrial fibrillation will not return to normal sinus rhythm on its own and will require some form of treatment.
  • Long-standing AFib is when the heart is consistently in an irregular rhythm that lasts longer than 12 months.
  • Permanent AFib occurs when the condition lasts indefinitely and the patient and doctor have decided not to continue further attempts to restore normal rhythm.
  • Nonvalvular AFib is atrial fibrillation not caused by a heart valve issue.

Over a period of time, paroxysmal fibrillation may become more frequent and longer lasting, sometimes leading to permanent or chronic AFib. All types of AFib can increase your risk of stroke. Even if you have no symptoms at all, you are nearly 5 times more likely to have a stroke than someone who doesn’t have atrial fibrillation.

How are heart attack symptoms different from AFib symptoms?

Fluttering and palpitations are key symptoms of AFib and are the key differences, but many heart problems have similar warning signs. If you think you may be having a heart attack, DON’T DELAY. Get emergency help by calling 9-1-1 immediately. A heart attack is a blockage of blood flow to the heart, often caused by a clot or build-up of plaque lodging in the coronary artery (a blood vessel that carries blood to part of the heart muscle). A heart attack can damage or destroy part of your heart muscle. Some heart attacks are sudden and intense — where no one doubts what’s happening. But most heart attacks start slowly, with mild pain or discomfort. Often people affected aren’t sure what’s wrong and wait too long before getting help.

People living with AFib should know the Warning Sings

As stated earlier, having atrial fibrillation can put you at an increased risk for stroke. Here are the warning signs that you should be aware of:

Heart Attack Warning Signs

Chest Discomfort

Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes, or that goes away and comes back. It can feel like uncomfortable pressure, squeezing, fullness or pain.

Discomfort in Other Areas of the Upper Body

Symptoms can include pain or discomfort in one or both arms, the back, neck, jaw or stomach.

Shortness of Breath

With or without chest discomfort.

Other Signs

May include breaking out in a cold sweat, nausea or lightheadedness.

Stroke Warning Signs

Spot a stroke F.A.S.T.:

  • Face Drooping: Does one side of the face droop or is it numb? Ask the person to smile.
  • Arm Weakness : Is one arm weak or numb? Ask the person to raise both arms. Does one arm drift downward?
  • Speech Difficulty: Is speech slurred, are they unable to speak, or are they hard to understand? Ask the person to repeat a simple sentence, like “the sky is blue.” Is the sentence repeated correctly?
  • Time to call 9-1-1: If the person shows any of these symptoms, even if the symptoms go away, call 9-1-1 and get them to the hospital immediately.

Call 9-1-1 immediately if you notice one or more of these symptoms, even if they are temporary or seem to disappear.

10 ATRIAL FIBRILLATION FACTS THAT MAY SURPRISE YOU

  1. AFib affects lots of people.  Currently as many as 5.1 million people are affected by AFib — and that’s just in America. By 2050, the number of people in the United States with AFib may increase to as many as 15.9 million. About 350,000 hospitalizations a year in the U.S. are attributed to AFib.  In addition, people over the age of 40 have a one in four chance of developing AFib in their lifetime.
  2. AFib is a leading cause of strokes.  Nearly 35 percent of all AFib patients will have a stroke at some time. In addition to leaving sufferers feeling weak, tired or even incapacitated, AFib can allow blood to pool in the atria, creating blood clots, which may move throughout the body, causing a stroke. To make matters worse, AFib strokes are fatal nearly three times as often as other strokes within the first 30 days. And according to a recent American Heart Association survey, only half of AFib patients understand that they have an increased risk of stroke.
  3. The U.S. Congress recognizes the need for more AFib awareness. StopAfib.org, along with several other professional and patient organizations, asked Congress to make September AFib Month. On September 11, 2009, the U.S. Senate declared it National Atrial Fibrillation Awareness Month.
  4. Barry Manilow has AFib. In 2011, Manilow spoke to Congress about AFib, urging the House of Representatives to pass House Resolution 295, which seeks to raise the priority of AFib in the existing research and education funding allocation process. The resolution does not seek any new funding. Other celebs with AFib include NBA legends Larry Bird and Jerry West, politicians George H. W. Bush and Joe Biden, Astronaut Deke Slayton, Billie Jean King, music mogul Gene Simmons and Helmut Huber, the husband of daytime TV star Susan Lucci.
  5. Healthcare professionals often minimize the impact of AFib on patients.  According to recent research in the Journal of Cardiovascular Nursing, “Compared with coronary artery disease and heart failure, AFib is not typically seen by clinicians as a complex cardiac condition that adversely affects quality of life. Therefore, clinicians may minimize the significance of AFib to the patient and may fail to provide the level of support and information needed for self-management of recurrent symptomatic AFib.”
  6. AFib patients may go untreated.  AFib can fly under the radar as some patients don’t have symptoms and some may only have symptoms once in a while. Thus, patients may go for a year or two undiagnosed, and sometimes not be diagnosed until after they have a stroke or two. Because some health care professionals perceive that AFib doesn’t affect patients’ everyday lives, a common approach is to just allow patients to live with the condition. But…
  7. The quicker the treatment, the greater the chance AFib can be stopped.  For those who have AFib, information about the ailment and treatment options are imperative. The longer someone has AFib, the more likely they will convert from intermittent to constant AFib, which means it’s more difficult to stop or cure.
  8. AFib changes the heart.  Over time, AFib changes the shape and size of the heart, altering the heart’s structure and electrical system. Research at the University of Utah shows that this scarring (fibrosis) from long-term remodeling is correlated with strokes.
  9. Treatments continue to rapidly evolve.  For years, the standard treatment for AFib patients was to send them home with medications, some of which caused harm. Now there are additional options for stopping AFib, including minimally invasive ablation procedures performed inside and outside the heart. For stubborn and long-lasting AFib, open-heart surgery may provide a cure.
  10. You can make a difference in an AFib patient’s life.  This month, forward a link to someone you may know who could have the condition. Attend an AFib awareness raising event or webinar. Or share StopAfib.org siteand ALittleFib.org with patients and friends.  Something as simple as that can help someone become free of AFib.

Prevention and Risk Reduction

Although no one is able to absolutely guarantee a stroke or a clot is preventable, there are ways to reduce risks for developing these problems.

After a patient is diagnosed with atrial fibrillation, the ideal goals may include:

  • Restoring the heart to a normal rhythm (called rhythm control)
  • Reducing an overly high heart rate (called rate control)
  • Preventing blood clots (called prevention of thromboembolism)
  • Managing risk factors for stroke
  • Preventing additional heart rhythm problems
  • Preventing heart failure

Getting Back on Beat

Avoiding atrial fibrillation and subsequently lowering your stroke risk can be as simple as foregoing your morning cup of coffee. In other words, some AFib cases are only as strong as their underlying cause. If hyperthyroidism is the cause of AFib, treating the thyroid condition may be enough to make AFib go away.

Doctors can use a variety of different medications to help control the heart rate during atrial fibrillation.

“These medications, such as beta blockers and calcium channel blockers, work on the AV node,” says Dr. Andrea Russo of University of Pennsylvania Health System. “They slow the heart rate and may help improve symptoms. However, they do not ‘cure’ the rhythm abnormality, and patients still require medication to prevent strokes while remaining in atrial fibrillation.”

AFib Treatment Saves Lives & Lowers Risks

If you or someone you love has atrial fibrillation, learn more about what AFib is, why treatment can save lives, and what you can do to reach your goals, lower your risks and live a healthy life.

If you think you may have atrial fibrillation, here are your most important steps:

  1. Know the symptoms
  2. Get the right treatment 
  3. Reduce risks for stroke and heart failure

21 Health Benefits and 6 Cool Facts About Zucchini

A staple at many markets and bountiful in backyard gardens during this time of year, zucchini can range in color from yellow to deep green. It has a tender texture with a slightly sweet flavor and, at just 21 calories per cup, it makes a welcome addition to a calorie-controlled diet.

Today, August 8th, is National Zuchinni Day and Sneak Some Zucchini on Your Neighbors’ Porch Day, so let’s take a look at all the potential benefits of this SuperFood.

What Is Zucchini?

Often known globally as courgette, zucchini is a summer squash native to the Americas. It belongs to the species Cucurbita pepo, along with a few other types of squashes and pumpkins. Zucchini boasts a rich nutritional profile, and it offers many health benefits thanks to its phytonutrients, mineral and vitamin content, including:

Vitamin C

Zucchini serves as a good source of vitamin C. A water-soluble antioxidant, vitamin C dissolves in your body fluids and protects your cells from free radicals, which are highly reactive compounds that oxidize your DNA, lipids and proteins, causing cellular damage. Getting enough vitamin C in your diet also aids in nerve cell communication, helps your body metabolize cholesterol and keeps your tissues strong. A cup of chopped zucchini contains 22 milligrams of vitamin C, which is 24 percent of the recommended daily intake for men and 29 percent for women, set by the Institute of Medicine.

Lutein and Zeaxanthin

Zucchini also provides you with lutein and zeaxanthin, two phytonutrients that belong to the carotenoid family, which is the same nutrient family that includes beta-carotene, a source of vitamin A. Lutein and zeaxanthin promote healthy eyesight. They filter light rays as they enter your eye, helping to ensure that harmful rays can’t damage your eye tissues. While, as of September 2013, the Institute of Medicine has not set a recommended daily intake for lutein and zeaxanthin, the American Optometric Association notes that intakes of at least 6 milligrams per day can reduce your risk for age-related macular degeneration, an eye disease that causes blindness. A cup of chopped zucchini provides 2.6 milligrams of lutein and zeaxanthin, or 43 percent of this intake goal.

 Manganese

Consuming zucchini also boosts your intake of manganese, an essential mineral. Like vitamin C, manganese protects your tissues from harmful free radicals. It supports the function of glycosyltransferases, a family of proteins that promote healthy bone tissue development. Manganese also helps your body produce collagen essential for efficient wound healing. Each cup of chopped zucchini boasts 0.22 milligram of manganese. This provides 12 and 10 percent of the Institute of Medicine’s recommended daily intake for women and men, respectively.

 Other Cool Zucchini Facts

  • One zucchini is called zucchina.
  • The world’s largest zucchini was 69 1/2 inches long and weighed close to 30 kilos.
  • Zucchini is the only fruit that starts with the letter Z.
  • The most flavorful of zucchinis are usually small and have darker skin.
  • Even the flower of the zucchini plant is edible. You can fry the zucchini blossoms into a delicacy.
  • And lastly, the word zucchini comes from ‘zucca’, which is the Italian word for squash.

Benefits Of Zucchini

  1. Zucchini Benefits For Weight Loss

It’s super low in calories, making it the perfect light side dish for a heavy meal; one cup of sliced zucchini has about 19 calories. That’s 40 to 50% lower than the same serving size for other low-cal green veggies like broccoli and Brussels sprouts. And because it’s so versatile, you can enjoy this low-calorie food in so many different recipes, from baked fries to pesto roll-ups. Of course, you can always grill zucchini with herbs for some savory flavor, too.

Zucchini is a low-starch fruit, low in carbohydrates and high in fiber. It will fill you up and discourage overeating.

The fruit also has a high water content which can keep you full for longer periods. It is one of those foods with a low glycemic index. Increased intake of fruits and vegetables and low-fat foods has been linked to healthy weight loss and weight maintenance.  Another benefit of high-fiber foods is they require more chewing – an individual, therefore, takes more time to eat and is typically unable to gorge on a large number of calories in a brief period.

  1. Improves Heart Health

Zucchini has a good amount of potassium: 295 milligrams per cup, or 8% of your recommended daily value. According to the American Heart Association, potassium can help control blood pressure because it lessens the harmful effects of salt on your body. Studies suggest boosting your potassium intake (while also curbing sodium) can slash your stroke risk and may also lower your odds of developing heart disease.

Because it is high in the antioxidant vitamin C, zucchini may help the lining of your blood cells function better, lowering blood pressure and protecting against clogged arteries. One cup of sliced zucchini has 20 milligrams, or about 33% of your daily value.

Ever heard of DASH diet? Also called the Dietary Approaches to Stop Hypertension, this diet is aimed at improving heart health by lowering hypertension. According to a report published by the National Heart, Lung, and Blood Institute, zucchini is a prominent part of the DASH diet.

Zucchini is low in cholesterol, sodium, and fat, and helps maintain a balance of carbohydrates – a requirement for optimum heart health.

Another reason zucchini works great for the heart is the presence of fiber. High intakes of fiber have been associated with significantly lower risks of developing stroke, hypertension, and heart disease.

Zucchini is also rich in folate, and as per a Chinese study, folate intake is inversely associated with heart disease risk.   The fact that it is rich in other nutrients like potassium and magnesium makes zucchini a superfood for the heart. Research has stated that deficiencies in the two nutrients can be directly linked to heart failure.

Another nutrient in zucchini that is worth your attention is riboflavin, which is a B-complex vitamin essential for energy production. In one study, children with cardiac disease were found to be shockingly deficient in riboflavin, emphasizing on the possible link between riboflavin and heart health.  Another Chinese study has linked riboflavin with alleviated cardiac failure in diabetics.

Riboflavin deficiency is also linked to certain birth defects in pregnant women, especially issues with the outflow tracts in the infant’s heart.

  1. Improves Eye Health

One doesn’t need to be reminded of the importance of vision. That said, zucchini seems to be more than food for your eyes. The fruit is rich in lutein and zeaxanthin, two antioxidants that were found to prevent age-related macular degeneration.

It is shocking to note that certain serious (and often irreversible) eye diseases like glaucoma and age-related macular degeneration have no warning signs.  So, what’s the best approach? Including zucchini in your diet. Zucchini is also a good source of vitamin A, shown to improve eye health.  It is important for eye development and maintenance.  As per a report published by Flaum Eye Institute of the University of Rochester Medical Center, a low-fat diet could be beneficial for the eyes – and zucchini can very well be a part of this diet.

The squash is also a wonderful source of beta-carotene that can improve eye health and offer protection against infections.

  1. Helps Control Diabetes

It is but unfortunate that a household without a diabetic is a rare scene. Well, that’s the sad part. So, is zucchini good for diabetics? Yes, the good part is, zucchini can help.

Non-starchy foods like zucchini can fill you up and aid diabetes treatment.  And the dietary fiber, which zucchini is replete with, can delay glucose absorption and help the patients with type 2 diabetes.  A German study states that insoluble fiber (which zucchini has a good amount of) can be very much effective in preventing type 2 diabetes.  Another study indicates the efficacy of insoluble dietary fiber that has shown to reduce diabetes risk.

Higher fiber intake is also associated with a lower risk of metabolic syndrome, which is one of the factors contributing to diabetes.  According to the University of Maryland Medical Center, soluble fiber can improve glucose tolerance in diabetics. Zucchini contains both soluble and insoluble fiber, by the way.

  1. Helps Lower Cholesterol

Zucchini is one of the few foods that are free of cholesterol, and hence you can include it in your cholesterol-lowering diet.  Soluble fiber has been found to interfere with cholesterol absorption. This helps lower the bad cholesterol or LDL in the blood.

  1. Helps Improve Asthma

In one Iranian study, the high levels of vitamin C in zucchini were thought to even cure asthma.  The anti-inflammatory properties of zucchini also contribute to asthma treatment.

Along with the vitamin C, zucchini also contains copper that is far more effective in treating asthma.

One Finnish study has found the benefits of vitamin C in treating not only asthma attacks, but also bronchial hypersensitivity — a characteristic of asthma.

  1. Protects Against Colon Cancer

The fiber in zucchini is the most important reason it can help in the treatment of colon cancer.  The fiber does multiple things – it absorbs the excess water in the colon, retains enough moisture in the fecal matter, and helps it to pass smoothly out of the body. Though precise knowledge about the subtypes of fiber (soluble or insoluble) in this aspect is important, dietary fiber as a whole has been linked to a reduced risk of colorectal cancer.

As per a Los Angeles study, dietary fiber plays a vital role in regulating the normal intestinal functioning and maintaining a healthy mucus membrane of the intestine. Though the exact amount of fiber and the type is still not clearly known, an expert panel from the study had recommended a fiber intake of 20 to 35 grams per day to prevent colon cancer.

The lutein in zucchini may also reduce the risk of colon cancer.

  1. Enhances Digestion

According to a report published by the University of Rhode Island, green fruits and vegetables, like zucchini, promote healthy digestion.  You can have zucchini as an after-meal snack – simply shred some carrots and zucchini on a quick bread or muffins and relish the taste and health benefits.

In fact, the late Henry Bieler (a prominent American physician who championed the idea of treating disease with foods alone) used to treat digestive issues in his patients with a pureed soup broth made from zucchini.   The dietary fiber in zucchini adds bulk to your diet and aids digestion. However, ensure you introduce fiber in your diet gradually. Increasing dietary fiber in your diet too quickly can lead to bloating, abdominal cramps, and even gas.

It has been found that dietary fiber forms the major components of foods that have low energy value, and hence are of particular importance, especially when it comes to dealing with abdominal issues.  If you are suffering from digestive issues, simply including zucchini in your meal might do the trick. It has been found that the addition of fiber in bread, cookies, breakfast cereals, and even meat products was found to have desirable results.

Zucchini contains both soluble as well as insoluble fiber. The insoluble fiber, also known as ‘the regulator’, accelerates the passage of water through the digestive tract. This reduces the time available for harmful substances to come in contact with the intestinal walls.

Seek out all-natural sources of fiber, and not just zucchini alone. If you are purchasing fiber-rich foods from the supermarket, there is but one ground rule – a good source of fiber is one that has at least 2.5 grams of fiber per serving. Foods having more than 5 grams of fiber per serving are excellent.  Anything lower than 2.5 grams could just be a waste of money.

  1. Lowers Blood Pressure

If you walk down a random street and pick any person you first see, chances are they might be (or is likely soon to be) suffering from high blood pressure.  We are so stressed about everything in life that blood pressure issues have become inevitable…almost.

With zucchini by our side, there is hope for natural relief.  Zucchini, being rich in potassium, is one of the preferred foods to combat hypertension.  Surprisingly enough, zucchini has more potassium than a banana.

Potassium is vasoactive, meaning it can affect the diameter of blood vessels. And hence, the blood pressure as well.  In a London study, potassium supplementation was linked to lowered blood pressure levels.  Though the study talks about certain conflicting results in pertinence to oral potassium supplementation, potassium was never shown to elevate the blood pressure levels.

As per another New Orleans study, potassium intake is mandatory to combat hypertension, especially when the individual is unable to reduce his/her sodium intake.  In addition to controlling blood pressure, potassium also lowers the heart rate and counters the harmful effects of sodium.

According to the National Academies Press, the adequate intake of potassium for adults is 4.7 grams per day.  Echoed by the World Health Organization, this dosage of potassium had the greatest impact on blood pressure levels.  However, dosing might vary depending on the overall health of an individual. Hence, consult your doctor for further details.

So, why is potassium so important with respect to lowering blood pressure? Because the nutrient is one of the principal electrolytes in the human body.  It is required in proper balance with sodium, in a ratio of 2:1. The junk foods we so very lovingly consume every other day have higher levels of sodium than potassium. Which is why they contribute to high blood pressure like no other. Zucchini is a good source of potassium. A medium-sized fruit offers 512 milligrams of the nutrient, which roughly equals 11% of your daily need.

  1. Slows Down Aging

Anti-aging is a big market today – a multi-billion dollar industry. You probably wouldn’t have to contribute much to that segment if you have zucchinis in your kitchen.

Zucchini is a good source of the antioxidants lutein and zeaxanthin. These two carotenoids exhibit powerful anti-aging properties.  They protect the cells of the body and the skin from free radical damage, which may otherwise lead to premature aging. Lutein and zeaxanthin have also been found to lighten the skin and improve its health.

In a study, lutein was found to prevent cell loss and membrane damage.  It also has photoprotective properties that protect the skin from UV damage. Zucchini is also rich in beta-carotene, the low levels of which were found to increase mortality risk in older men.

The riboflavin in zucchini maintains the health of the skin, hair, nails, and mucus membranes. It slows down aging by boosting athletic performance and preventing age-related memory loss and other related conditions like Alzheimer’s disease.  In one study, riboflavin was found to prolong the lifespan of fruit flies – indicating a similar possibility in human beings.

Zucchini, as we have seen, is rich in vitamin C. According to a South Korean study, the vitamin was found to decelerate aging in human heart cells.  Also, vitamin C is found in high levels in the skin layers, and the concentration shows a decline when we age.  Hence, intake of vitamin C appears to be a logical solution to slow down the signs of aging.

  1. Strengthens Bones And Teeth

Green vegetables and fruits, like zucchini, promote stronger bones and teeth,  The lutein and zeaxanthin in zucchini keep the bones and teeth strong. In addition, they also strengthen the blood cells.  Zucchini also contains vitamin K, which contributes to stronger bones.

Magnesium is another nutrient abundant in zucchini.  Most of the body’s magnesium resides in the bones, which helps build strong bones and teeth.  Magnesium also works along with calcium to improve muscle contraction.

The folate in zucchini also protects the bones, as does beta-carotene. Studies show that the body converts beta-carotene into vitamin A, which contributes to bone growth.

Zucchini contains phytochemicals such as indoles, which, according to Rutgers Cancer Institute of New Jersey, maintain strong bones and teeth.  Similar findings have been published by the California Department of Public Health.

  1. Helps Balance Thyroid And Adrenaline Function

Zucchini is rich in manganese, a mineral that promotes the optimal functioning of the thyroid gland.

  1. Helps During Pregnancy

Dark green vegetables are a must during pregnancy, and zucchini is one of them. In the nine months of pregnancy, consuming zucchini offers adequate B-complex vitamins that help maintain the energy levels and mood.

Zucchini is rich in folic acid that has shown to reduce the risk of certain birth defects,  like spina bifida – baby’s spinal chord doesn’t develop properly –  and anencephaly – the absence of a major portion of the brain.  As per a Canadian study, over 50 countries that have fortified their food staples with folic acid saw a dramatic decrease in neural tube defects in pregnant women.

One more reason folate is beneficial to pregnant women is its ability to aid in the production of red blood cells in the body.  This also helps lower the risk of developmental problems in the baby during pregnancy.

It is important to keep in mind that folic acid (or folate) works best when taken before getting pregnant and during the first trimester.  As women need additional folic acid during pregnancy, it is advisable to take a folic acid supplement as well.  Around 400 mcg of folic acid per day is recommended for women in this aspect.

Another reason zucchini is good for pregnancy is its magnesium content. As per an Italian study, magnesium is very important for women with an elevated risk of gestosis or premature labor.

  1. Good For Babies (And Kids)

Diarrhea is one common problem amongst most kids over one year of age. Oh yes, there are medications. But changes in the diet can also help. Bland foods work well in this case, and peeled zucchini can do wonders.

Mashed zucchini can also be a good addition to your baby’s diet.  Since it is soft and bland in taste (and since it comes replete with nutrients), your baby will be able to consume it easily.   NOTE: Never leave a baby alone when he/she is eating. Keep the portions small. And avoid those foods that he/she can easily choke on – these include everything that is hard to chew.

There is likely no need to emphasize the negative effects smoking can have on pregnant women. But, what if a woman has been a smoker for a long time before getting pregnant and just can’t give the habit up? In one Portland study, the intake of vitamin C has been found to prevent lung problems in babies born to pregnant smokers.  Zucchini, being rich in vitamin C, can help in this regard. By the way, this doesn’t mean it is okay to smoke during pregnancy. It simply isn’t.

In another Denmark study, the deficiency of vitamin C was found to impair brain development in infants.  In fact, the importance of vitamin C for infants was discovered way back in the early 1900s.

Studies conducted then stressed the significance of vitamin C in preventing scurvy in infants.  Dr. F.R. Klenner, between 1948-49, cured polio in children with vitamin C, and vitamin C only.  Of course, polio is nearly eradicated today. Both show how important vitamin C has been in the improvement  of population health.

  1. Helps Prevent Gout

Zucchini’s vitamin C grabs the spotlight, yet again. One study has linked vitamin C intake with a lower risk of gout in men.  It achieves this by lowering serum uric acid levels via a process called the uricosuric effect. The vitamin was also found to prevent not just gout, but numerous other urate-related diseases as well.

You can also intake zucchini to complement your gout treatment, especially if your treatment isn’t working well. As with every health concern, dosage is important, so talk to your doctor.

Though gout generally affects men over the age of 40 or anyone with a family history of the disease, it can occur anytime to anyone. It is caused by the excessive build-up of uric acid in the body, leading to its accumulation in tissues in the form of needle-shaped crystals. Apart from taking zucchini and other foods rich in vitamin C, something as simple as drinking 6 to 8 glasses of water daily can prevent gout.

  1. Promotes Prostate Health

When it comes to men’s health, zucchini is one of the vegetables that is often overlooked, but its phytonutrients greatly benefit the prostate.  The high carotenoid content of zucchini also associates it with a reduced risk of prostate cancer.

We have seen that zucchini is rich in beta-carotene and vitamin C. Both of these nutrients, as per a study, were found to be positively associated with prostate cancer.  Vitamin C reduces oxidative DNA damage and hampers the growth and ability of prostate cancer cells.

Lutein is also found in zucchini. As per a report published by the University of California San Francisco, lutein intake is inversely associated with prostate cancer.

Dietary fiber has been found to bind with carcinogens and eliminate them from the body. It also has the ability to prevent prostate cancer progression, and phytonutrients protect the cells from damage.  Both of these healthful compounds are abundant in zucchini, making it a powerful weapon to combat prostate cancer.

  1. Aids Collagen Formation

As we have seen, zucchini contains riboflavin, whose deficiency was found to affect the maturation of collagen.   The vitamin C in the squash plays a major part in the synthesis of collagen, which, as we know, is quite important to maintain the health of joints, cartilage, skin, and blood vessels.  The vitamin also protects the body from cellular damage.  In addition to collagen, vitamin C also helps in the production of elastin, both of which are essential for radiant and healthy skin.

A few other nutrients contribute to collagen formation, like potassium, zeaxanthin, and folate.  Zucchini is replete with these.

  1. Helps In Skin Hydration

Zucchini hydrates the body (and the skin) and helps it deal with the summer heat.

The lutein in zucchini encourages skin health by reducing inflammation responses. But how does that promote skin hydration? Well, here’s the science behind it. When the skin is exposed to sunlight, lutein reduces the inflammation response. This means the sunlight will cause less damage to the skin, and that means less damage to the moisture barrier of the skin as well.  And the result? Well hydrated skin.

Zucchini is 95% water.  This translates to hydrating the skin well. Keep in mind  only about 20% of our daily water intake is met through foods. Hence, it is also important we drink 8-10 glasses of water every day as skin cells need water to function at their best.

  1. Improves Brain Functioning And Memory

Green foods, especially zucchini, are rich in folate and are excellent for brain health.  Folate also helps in the production of DNA and RNA, the body’s genetic material. The nutrient, apart from improving mental health, also enhances emotional health.

The deficiency of folate is linked to megaloblastic anemia, which results in weakness and fatigue. Increased folate intake has been linked to reduced risk of dementia and Alzheimer’s disease in women.

Also, our brain is 75% water. When there is adequate water in your system, you will be more focused, think quick, and also display greater creativity. More importantly, sufficient water efficiently delivers nutrients to your brain and aids toxin removal. This results in enhanced concentration and mental alertness.  Zucchini, apart from being rich in water, also contains vitamin C, zinc, and omega-3 fatty acids – all of which largely contribute to brain health.

Though not very rich in iron, zucchini contains the nutrient in acceptable amounts. As per a study, early iron deficiency can lead to permanent neurobehavioral problems despite diagnosis and treatment.  Early iron deficiency can even affect the brain’s physical structure. Iron is also important for producing myelin, the fatty sheath that coats the brain’s nerves and accelerates brain communications.

  1. Promotes Hair Growth

Zucchini, being rich in zinc, promotes hair growth.  The vitamin C in zucchini can help heal dry and splitting hair.  It also makes your hair strands strong and supple.  Lack of vitamin C can result in the enlargement of hair follicles, which might eventually stall hair growth.

  1. Enhances Immunity

The vitamin C found in zucchini is an active form of ascorbic acid that boosts the immune system, and it does this in several ways. First, vitamin C helps develop the body’s T cells (a type of white blood cell) into functional T cells that defend against diseases. It also helps you produce more immune cells. The antioxidant properties of vitamin C also prevent cells from dying due to inflammation. The RDA of vitamin C is 90 mg in males and 74 mg in females.

Low levels of vitamin C are linked to increased risk of infection. In fact, high levels of vitamin C are frequently recommended for HIV-positive individuals to enhance their immunity.

In a Switzerland study, vitamin C and zinc were found to enhance immunity, so much that they had even improved the health of patients suffering from certain immune-deficient diseases like malaria and diarrhea.

Potential Side Effects Of Consuming Zucchini

  1. Digestive issues

Zucchini might cause digestive issues in people suffering from Irritable Bowel Syndrome (IBS). In such a case, consume it with caution, or avoid it altogether.  Bitter zucchini might also cause stomach cramps, diarrhea or both,

  1. Allergies

Zucchini might cause allergies in individuals who are sensitive to it. These include nausea, pruritus (severe skin itching), and certain kinds of oral allergies.

  1. Alzheimer’s

Yes, this can be contradictory to what was covered earlier in the article. Iron does help prevent brain ailments. But studies suggest that too much of it can cause neurological conditions like Alzheimer’s.  Though iron is not abundant in zucchini, it still is better to consider its effects.

  1. Excessive beta-carotene

Since zucchini is a very good source of beta-carotene, this could be a concern for certain individuals. Large doses of beta-carotene might be inadvisable for pregnant and lactating women, people who smoke, people who have been exposed to asbestos, and individuals who have undergone angioplasty.

Beta-carotene might also interact with medications – especially those used for lowering cholesterol and other medicines like niacin.

How much of zucchini is too much?

These side effects need not worry you unless you happen to take zucchini in excess. It sure is a super-food, yet there is conflicting information about just how much is too much, so please consult your doctor for more guidance.

 Zucchini – Tips For Selection And Storage

How to select zucchini

Zucchini is usually picked and sold even before it matures. Hence, the seeds and skin are tender, and you can cook it even without peeling. The zucchini must be clean and blemish-free. You must be able to pierce the skin easily with your fingernail.

Also, ensure the zucchini you select is small to medium in size – no more than 6 to 8 inches, and free of pricks and cuts. Some say it is better if it has one inch of stem attached.

How to store zucchini

Zucchini must be stored in a refrigerator. Remember to wrap it tightly.

If you want to freeze zucchini, choose the one with tender skin. Wash and slice it and scald for 3 minutes. Cool and drain and then pack it in a freezer container. You can also freeze shredded zucchini, provided you do it immediately.

If you are planning to grow zucchini in your backyard, you must remember that it grows best when surrounded by mulch, which keeps the soil moist. You also need to add two inches of water every week for the plant to thrive.

How To Prepare Zucchini

  1. As a healthy snack

Simply take raw zucchini sticks or slices and enjoy them with your favorite dip. You can also pack them in your lunchbox for a healthy afternoon snack.

  1. Mashed Zucchini

Wondering what to use as a side dish for your meal? Zucchini! Steam it and mash it. You can then puree this with other root vegetables and serve. Much better (and healthier) than mashed potatoes!

  1. Grilled Zucchini

Who said only meat can be thrown on the grill? Slice zucchini into 1/2-inch thick disks, or cut the zucchini lengthwise, and brush them with cooking oil.  Season as you desire, and grill right on the grate.

  1. Stuffed Zucchini

Pretty simple: Cut the zucchini lengthwise and scoop out the insides. Fill the empty zucchini cups with chopped vegetables, meat, and cheese. Bake for about 40 minutes at 375° F, or until they turn golden brown. Serve while hot.

  1. Use in salads

Make your salad healthier by slicing in zucchini.

Can you eat zucchini skin?

In fact, you should, as zucchini is 95% water. Most of this water is found in the flesh – which means most of the nutrients are found in the skin. Peeling the skin deprives you of vitamins C and K, fiber, potassium, antioxidants, and the other nutrients. Eating zucchini without the skin is almost like drinking plain water – only that you would be chewing in this case.

How To Make Zucchini For Baby

Zucchini can be wonderful for babies. It has a mild flavor. It is soft to chew, and it offers super nutrients.

But, remember this – zucchini, particularly because of its skin, can cause a bit of stomach upset in some individuals. Hence, you must wait till your baby is eating stage 2 foods, which would happen when (s)he is around 8 months old.

In case your child is prone to stomach upsets, peel the zucchini before cooking and observe how your child receives it. If things are alright, try with the skin the next time.

Here is how you can cook zucchini for your child:

  1. Select a zucchini with a firm and shiny skin. It must be free of bruises and any other visible damage. Keep it unwashed in a plastic bag and store it in the refrigerator (until you are ready to cook it, which would usually be up to 4-5 days).
  2. Divide the zucchini widthwise into half. Prepare the zucchini one half at a time. You can keep the second half back in the refrigerator until you want to use it next time.
  3. Slice the end of the zucchini. Wash it thoroughly under a stream of cold water.
  4. Cut it into thin slices.
  5. Fill a saucepan with cold water and bring it to a boil.
  6. Add the sliced zucchini to it. Once the water boils, decrease the heat to medium.
  7. Keep boiling the zucchini until it turns tender – this should take about 10 minutes.
  8. Drain the water and transfer the boiled zucchini into a food processor. Process it until it is completely pureed. You can add a little cold water if it appears too thick.
  9. Wait till the puree cools before you feed it to your little one. You can store the leftovers in a sealed container in the refrigerator for up to 2 days.
  10. You can prepare the other half of zucchini in a similar way.

As always, it is best to consult your baby’s pediatrician before introducing new foods in his/her diet.

Conclusion

Celebrate the  end-of-summer with the super food zucchini . Try grated zucchini in cookies and bread for added moisture, or, stuff between tortillas for a simple veggie quesadilla.  Packed with beneficial nutrients, including Vitamins C and A, potassium, folate, and fiber, zucchini contributes to a healthy heart by decreasing the risk of stroke, reducing high blood pressure, and lowering cholesterol. Get maximum benefits by eating either raw or cooked zucchini and feel free to eat the skin– it’s edible.

Top Health News | Stress at Work Could be Harming Your Heart

Job strain could be harming your heart

Published
Individuals with high-strain jobs are more likely to develop atrial fibrillation, which is a common heartbeat disorder that can significantly raise the risk of stroke.

 

This was the conclusion of a new Swedish study on work stress, now published in the European Journal of Preventive Cardiology.

The researchers define “high-strain jobs” as those that are “psychologically demanding” but give job-holders little control “over the work situation.”

Examples include bus driving, nursing, and working on assembly lines.

Previous studies have linked work stress to coronary heart disease, but whether there is also a link to atrial fibrillation (A-fib) is less clear.

According to first study author Eleanor I. Fransson, who is an associate professor of epidemiology at Jönköping University in Sweden, A-fib “is a common condition with serious consequences and therefore it is of major public health importance to find ways of preventing it.”

A-fib and consequences

A-fib affects millions of people in the United States. It occurs when the upper two chambers of the heart (the atria) beat abnormally and disrupt blood flow to the lower two chambers (the ventricles).

The condition, which can be temporary or permanent, raises the risk of stroke. A person with A-fib has a four to five times higher risk of having a stroke than a person without it.

As well as irregular heartbeat, individuals with A-fib might also experience: chest pain, palpitations (a fluttering or pounding sensation in the heart), shortness of breath, feeling lightheaded, and “extreme fatigue.”

However, some people with A-fib may have no symptoms and not even realize that they have it.

Each year in the U.S., A-fib is responsible for over 750,000 hospital admissions and contributes to 130,000 deaths. Deaths in which A-fib is a contributory or primary cause have been increasing for the past 20 years.

The costs associated with A-fib are substantial. Overall, the burden in the U.S. amounts to $6 billion per year. The average annual medical bill for treating an individual with A-fib is $8,705 higher than for those without it.

Demands-control model

To assess work stress, Prof. Fransson and team used a measure of job strain that is based on the job demands-control model. It is one of the “most widely studied” models of work stress.

It is based on the idea that the effect of job demands on the strain that people experience is “buffered” by the amount of control that they have over their work.

For their study, the researchers used a Swedish questionnaire based on the model. It comprises five items on job demands and six on control.

The questions ask, for example, whether the individual:

  • has “to work very hard or very fast”
  • experiences conflicting demands in the job
  • has enough time to complete tasks
  • has to complete lots of repetitive tasks
  • is able to decide which tasks to do and how to do them

Link between job strain and A-fib

The researchers used data on 13,200 individuals who constituted a “representative sample of the working population” of Sweden. They were recruited in 2006, 2008, and 2010 to take part of the Swedish Longitudinal Occupational Survey of Health (SLOSH).

None of the participants had A-fib — or a history of the disorder — when they joined the study. Neither did they have a history of heart failure or heart attack.

They were all employed, and they all completed a battery of questionnaires when they entered the study. These were sent out by post and included the usual demographic questions plus others about health, lifestyle, and work.

The study followed the group for a median of 5.7 years. Using national registers, the researchers identified 145 cases of A-fib during this period.

Analysis of the SLOSH data — after adjusting for age, gender, and education — showed that job strain was linked to an almost 50 percent raised risk of A-fib.

The risk stayed the same when the team further adjusted the results to take into account the effect of exercise, smoking, blood pressure, and body mass index (BMI).

Stress, heart health, and the amygdala: Links explained

Published
That long-term stress is linked to cardiovascular disease is not breaking news. However, despite the well-known connection, exactly how the two are coupled has been difficult to pinpoint. Two studies published this week provide new insight.

 

Psychological stress carries with it a wealth of ills. In fact, excessive stress is known to contribute to a range of conditions, including hypertension (high blood pressure), ulcers, asthma, and irritable bowel syndrome.

It also has a well-documented impact on heart health. Some of this negative influence could be due to coping mechanisms – such as drinking alcohol or smoking tobacco – but there also appears to be a direct link between elevated stress levels and heart complaints.

Although this relationship is common knowledge to medical researchers and laypeople alike, the exact physiological processes behind it have remained difficult to unpick.

How can an emotion that is constructed in the brain influence the physical health of the heart?

While the link between stress and heart disease has long been established, the mechanism mediating that risk has not been clearly understood.”

Dr. Ahmed Tawakol, lead author

Studies in animals have found that stress increases the manufacture of white blood cells in bone marrow. This, in turn, leads to an increase in inflammation. How this fits into the full picture is yet to be understood.

Stress, inflammation, and heart health

Researchers from Massachusetts General Hospital (MGH) and Icahn School of Medicine at Mount Sinai (ISMMS) in New York designed a double-pronged investigation to gain insight into this fascinating question.

The results, published this week in The Lancet, provide new information regarding the links between cardiac health and psychological stress.

Dr. Tawakol’s paper describes two studies that aimed to combat the same problem in a similar way. The first study, conducted at MGH, analyzed positron emission tomograph (PET) and computed tomography (CT) scans of nearly 300 individuals. The scans utilized a radiopharmaceutical called fluorodeoxyglucose (FDG), which can simultaneously measure activity in the brain and the level of inflammation in arteries.

All participants were healthy at the time of the scan and had information in their medical records of at least three additional clinical visits within the following 5 years.

The second study was carried out at the Translational and Molecular Imaging Institute at ISMMS. This smaller study involved 13 participants with a history of post-traumatic stress disorder (PTSD). The researchers assessed their current levels of perceived stress and carried out FDG-PET scans.

In the larger MGH study, 22 participants experienced a cardiovascular event – such as stroke, angina, or a heart attack – during the follow-up period.

Dr. Tawakol and his team were able to show an association between the likelihood of a cardiac event and a specific part of the brain: the amygdala, a region known to be involved in emotional processing.

Stress and the amygdala

High levels of activity in the amygdala at the start of the study were associated with an increased risk of experiencing a cardiac event. Even after adjusting for other cardiovascular risk factors and atherosclerosis, the association was significant. The link became even stronger when the analysis only took into account more serious cardiac events.

They also showed that activity in the amygdala could predict the timing of the events. Higher levels of activity at baseline were associated with the occurrence of cardiac events sooner in time.

Greater activity levels in the amygdala were also associated with increased metabolism in regions of the body responsible for creating blood cells (bone marrow and spleen) and an increase in arterial inflammation.

The results from the smaller ISMMS study add weight to the MGH findings. Participants’ stress levels were, again, significantly associated with activity in the amygdala and arterial inflammation.

This pioneering study provides more evidence of a heart-brain connection, by elucidating a link between resting metabolic activity in the amygdala, a marker of stress, and subsequent cardiovascular events independently of established cardiovascular risk factors. We also show that amygdalar activity is related to increased associated perceived stress and to an increased vascular inflammation and hematopoietic activity.”

Zahi A. Fayad, Ph.D., co-senior author

Further research will help to deepen our understanding of the so-called amygdala-bone marrow-arterial axis. In the future, medications that target this mechanism may be useful for controlling or minimizing cardiovascular disease. The findings also underscore the importance of addressing stress in order to reduce health risks.

As Dr. Tawakol says: “It would be reasonable to advise individuals with increased risk of cardiovascular disease to consider employing stress-reduction approaches if they feel subjected to a high degree of psychosocial stress.”
