Why Fried Food Is Not Good For Older Women?

Every year, stroke affects nearly 800,000 people in the United States. It is the 4th leading cause of death in the United States.

A stroke, also known as a cerebrovascular accident (CVA), is the loss of brain functions because the blood supply to the brain is disturbed. Both ischemia (lack of blood flow) caused by blockage or hemorrhage (leakage of blood) could cause a stroke.

In a paper published on March 1, 2012 in the ‘Annals of Neurology’, researchers from University of North Carolina found that older women who ate high amounts of transfer fats found in fried foods and baked goods were at a greater risk of stroke than women who ate less fatty diets.

Data was taken from a large study on eating habits of 87,025 post-menopausal women, who aged between 50 and 79. These women were generally in good health at the time of enrolment.

The findings showed that women who ate diets high in trans-fatty acids (6.1 grams a day) had a 39 percent higher risk of stroke due to a blocked artery than women who ate 2.2 grams of trans-fatty acids per day. However, researchers did not find any significant association between stroke risk and how much total fats women ate, or their level of dietary cholesterol. They also found that aspirin could help lower the risk of stroke among post-menopausal women.

While the availability and consumption of trans fat have declined in the United States as a result of banning by public health and legislation campaign for the use of trans fat in many fast food restaurants and in food preparation, trans fat has not completely disappeared.

Trans fat commonly occurs in foods because of partial hydrogenation, a food processing method in which a liquid vegetable oil is transformed into a solid fat. Trans fat can lower the good cholesterol (high-density lipoprotein, HDL) and raise the bad cholesterol (low-density lipoprotein, LDL). This could in turn raise the likelihood of getting hypertension (high blood pressure), heart disease and of course stroke.

As such, researchers suggested that older women should adopt a diet low in trans fat and should also take aspirin to help lower their risk of stroke, especially at the onset of menopause.

On the other hand, health experts not involving in the study argued that it is possible that women who ate a lot of trans fat were also unhealthy: the might have less physical activity, smoke and have higher level of diabetes. Therefore, they recommend these women should have a balanced diet avoiding trans fat and including healthy oils and daily physical activity. They believed this would help prevent stroke and other lifestyle related disease including heart disease and hypertension.

It‘s Only The Calories Count, Not Source!

There is undoubtedly that overweight and obesity can bring along many unwanted ailments including high cholesterol, hypertension (high blood pressure), heart disease, stroke and even certain types of cancer. People who are overweight or obese will start to adopt different kinds of diet plan to help them reduce weight.

Different diet plan will have their own specified proportion of fat, carbohydrates and protein. It seems, however, that weight loss does not really depend on the source of the calories.

Researchers from Pennington Biomedical Research Center in Baton Rouge, Louisiana reported on January 18, 2012 in the ‘American Journal of Clinical Nutrition’ that there were no differences in weight loss or the reduction of fat between 4 diets with different proportions of fat, carbohydrates and protein. It is adherence that matters. Those participants who adhered better lost more weight than those who did not.

As shown in earlier research, certain diets like those with very low carbohydrates work better than others though there has been no consensus among researchers.

Participants were assigned to 1 of the 4 diets: Average protein, low fat and higher carbohydrates; High protein, low fat and higher carbohydrates; Average protein, high fat and lower carbohydrates; High protein, high fat and lower carbohydrates. All the diets were designed to reduce 750 calories a day.

Their weight, fat mass and lean mass were checked after 6 months and again at 2 years after starting the diets. At 6 months, participants lose more than 4.1 kilos of fat and approximately 2.3 kilos of lean mass, though they regained some of these at the 2-year mark. Nevertheless, people who managed to adhere to their diet were able to keep a weight loss of more than 3.6 kilos after 2 years including a nearly 1.4 kilos loss of abdominal fat, a drop of more than 7 percent.

During the 2-year period, many of the participants dropped out and those who completed it did not have the diets exactly the same as what had been assigned.

For instance, all the 4 diet groups ended up getting about 20 percent of their calories from protein after 2 years. This was quite different from what the researchers had hoped for: 2 diet groups get 25 percent of their calories from protein and the other 2 groups get 15 percent of their calories from protein.

The findings suggested that all diet plans can work and it is adherence that can help the weight loss success. People should choose the diet that is comfortable for them.

More Women Are Affected By Heart Disease!

It is thought that heart disease is more common among men. But as what NIH (National Heart, Lung and Blood Institute) has announced, heart disease is the number one killer of women in the United States and it is also a leading cause of disability among women.

Heart disease, rather than breast cancer, has become the number one killer for women in Malaysia. The statistics provided by the Heart Foundation Malaysia (HFM) showed that 1 in 3 women died of heart disease while only 1 in 8 women died of breast cancer. In fact, heart disease is the major cause of death in government hospitals, which accounted for about 25 percent of all deaths.

In Goa, a state in India, 10 to 11 percent of the population is being hit by heart diseases. While heart disease is spread across the genders, women seem to be leading and this is a situation that has never prevailed in Goa. Initially, heart disease was restricted to the age group above 50 years but now people between 30 and 40 are diagnosed with heart disease.

According to cardiac experts, more women die of heart disease especially after menopause when the oestrogen level in their body changes. When one grows older, the risk of getting heart disease also rises. However, the latest trend does show that those below the age of 40 have also developed heart disease due to their unhealthy eating habits, smoking and alcohol consumption. Other modifiable risk factors include high cholesterol level, high blood pressure, diabetes, obesity and stress.

It is important that the younger adults should adopt a healthy lifestyle by avoiding alcohol consumption and smoking, having a balanced diet, exercising at least 30 minutes or getting for a brisk walk everyday and learning how to handle stress.

People could lower their high cholesterol risk factor by consuming low cholesterol food items and avoiding food high in animal fat like dairy products, egg yolk, coconut milk and seafood except fish. People should also consume less salt, sugar and oily food to lower other risk factors such as hypertension (high blood pressure) and obesity.

Sleep Enough To Prevent Weight Gain!

People become overweight or obese because of many reasons. For instance, they might eat too much foods rich in saturated fats or they consume more calories than their bodies require. Most importantly, they do not have enough physical activities.

Once a person becomes overweight or obese, he or she is at a higher risk of developing hypertension (high blood pressure), heart disease, stroke and Type-2 diabetes.

As revealed by previous studies, lack of sleep can also lead to weight gain. Inadequate sleep could raise the hormone ghrelin that signals when to eat, and reduce hormone leptin that tells to stop eating. People who do not have enough sleep have less leptin and more ghrelin. Such imbalance of hormones can drive people to keep on eating.

On June 13, 2011, researchers from Harvard Medical School and McLean Hospital in Belmont, Mass reported at a meeting of the Associated Professional Sleep Societies in Minneapolis, Minn that people suffering from sleep deprivation are likely to be attracted to high calorie foods because these foods provide a sudden but not sustainable burst of energy.

In a paper that was published in the ‘American Journal of Clinical Nutrition’ in May 2011, researchers from Uppsala University in Sweden found that sleep deprivation could slow down metabolism causing the body to use less energy. The European study showed that lack of sleep not only cause weight gain but also slow the rate at which calories are burnt.

The explanation is that a one night of sleep deprivation could acutely reduce energy expenditure in healthy men, which suggests that sleep can regulate daytime energy expenditure in humans. The researchers therefore argued that getting plenty of sleep might prevent weight gain.

In the study, 14 male university students went through a series of sleep conditions, namely curtailed sleep, no sleep, and normal sleep, over several days. Measurements were recorded for the changes in how much they ate, their blood sugar, hormone levels and indicators of their metabolic rate.

Analysis indicated that even a single night of sleep deprivation slowed metabolism the next morning, reducing energy expenditure for tasks like breathing and digestion by 5 to 20 percent, compared with the morning after a good night's sleep. The young men also had higher morning levels of blood sugar, appetite-regulating hormones such as ghrelin, and stress hormones such as cortisol after sleep disruption.

To help people get more sleep, experts’ advice is to try to go to bed an hour earlier each night, limit caffeine and alcohol, and try to exercise 5 to 6 hours before bed.

How Can Mothers’ Work Status Be Linked To Childhood Obesity?

Childhood obesity epidemic has long been a headache for most countries around the world. Obese children are likely to be fat as they become adults and they are therefore facing a higher risk of developing Type-2 diabetes, hypertension (high blood pressure), stroke and heart disease.

Many factors can lead to childhood obesity, and one of them is mothers’ work status. Researchers from Melbourne's Murdoch Children’s Research Institute together with the University of New England and the Australian National University carried out a study to find out whether the childhood obesity epidemic was linked to mothers' increased participation in the workforce. They published their findings on March 3, 2010 in the ‘Journal of Social Science and Medicine’.

The researchers examined the weight and lifestyle of some 2,500 children when they were 4 or 5 and again when they were 6 or 7. They revealed in their report that between 18 and 20 percent of children were either obese or overweight.

According to the findings, mothers who work part-time were more likely to have healthier children than those who worked full-time or who were not working at all. These children watched less television, ate fewer snacks and were more physically active. On the other hand, mothers with full-time jobs might not have enough time to encourage physically active play or prepare home-cooked meals.

Nevertheless, the researchers cautioned public that the findings might oversimplify actual situation. For example, stay-at-home mothers might be difficult to juggle family time when there is more than one young child at home.

While the study indicated that work status indirectly contributed to children’s lifestyle, some health experts argued that these things are controllable. Whether the mothers are working, they could still control how much television their child watches and what types of snacks they can eat. Others quoted parental distress, postpartum depression and lack of social support as variable that could account for children having less-healthy lifestyles.

More Pregnant Women Are Having Strokes!

It is unlikely that women would have stroke during pregnancy or shortly after giving birth. However, researchers from Centers for Disease Control and Prevention's Division for Heart Disease and Stroke Prevention in Atlanta, Georgia have spotted a big jump in such events over the past 12 years.

The findings, which were published on July 28, 2011 in ‘Stroke’ (Journal of the American Heart Association), showed that there was a total of 4,085 pregnancy related stroke hospitalizations in the United States during the period between 1994 and 1995, and that number rose 54 percent to 6,293 between 2006 and 2007. The data used in the study came from a large national database of 5 to 8 million discharges from 1,000 hospitals.

Some increase was expected, but the figures found in the findings indeed surprised the researchers. Overall incidence is still low as latest data indicated that just three-quarters of a percent of women in America had a stroke during pregnancy or within 3 months of giving birth.

One factor could be responsible for the rise is that more women are overweight when they become pregnant, which can raise the likelihood of complications from diabetes and high blood pressure. Nevertheless, it was wished that more research should be designed and carried out to find the cause of the rise.

Stroke risk is usually low for a relatively healthy person. As pregnancy by itself is a risk factor for stroke and more pregnant women already have some kind of risk factor for stroke like obesity, hypertension (high blood pressure), diabetes or congenital heart disease, the overall risk will simply be doubled.

It was also observed that doctors do not have enough guidance on the best medication for pregnant women, especially for those with an increased risk for stroke. This is because norms on clinical studies usually exclude pregnant women in clinical trials as most drugs pose a hazard to the unborn fetus.

The researchers suggested developing a comprehensive, multidisciplinary plan that would enable doctors and patients to follow guidelines that could accurately monitor and provide care before, after and during childbirth.

Another Cause For Children Obesity!

Childhood obesity is a serious issue as obese children are at a much higher risk of developing many chronic diseases including diabetes, heart disease, hypertension (high blood pressure), stroke and even certain types of cancer later in their life.

Sedentary lifestyle and unhealthy diet have been crowned as the main culprits responsible for childhood obesity. However, researchers from Temple University had recently found a new cause.

In a paper published in the ‘Journal of Pediatrics’, they reported that toddlers who still drank from bottles at age of 2 were 33 percent more likely than other children to be obese at the age of 5.

Of the 6,750 children studied, 1 in 5 was still using a bottle at the age of 24 months, either at night or all the time. For those who were long-term bottle users, roughly 1 in 5 was obese at the age of 5, comparing to about 1 in 6 that has been weaned earlier.

After looking into other factors that could affect a child's risk of obesity, including mother's weight, family income and education, and if the child had ever been breastfed, the researchers found that prolonged bottle-feeding by itself could induce a 33 percent increase in children's risk of obesity.

According to researchers, the bottle might be providing a source of comfort, rather than meeting nutritional needs. Nevertheless, the extra calories could be substantial. For instance, for an average 2-ear-old girl, an 8-ounce bottle of whole milk fed at bedtime would provide 12 percent of her calorie needs for the day.

Though the findings could not conclude long-term bottle-feeding is directly responsible for the increased risk of obesity, they did suggest that weaning babies around 12 month old could help prevent weight gain.

In fact, pediatricians already advise parents to wean their children when they are about 12 to 14 months old, or even earlier. This is mainly because extended bottle-feeding, especially overnight, is believed to boost the risk of cavities and might contribute to iron deficiency.

Why Should Junk Food Advertisements Be Banned?

Children obesity has been a headache for not only developed but also many developing nations. Overweight or obese children will have a higher risk of developing chronic diseases like hypertension (high blood pressure), heart disease, Type-2 diabetes and stroke later in their life.

Inadequate physical activity and unhealthy diet are the 2 main reasons identified by health experts that cause the childhood obesity. Children tend to watch long hours of television and eat a lot of junk foods.

In a paper published in June 2011 in the journal ‘Pediatrics’, researchers from the University of Liverpool in the United Kingdom reported that television advertisements for junk food really make children hunger for those treats, especially if they watch a lot of television.

A DVD featuring commercials for fast food and junk food seemed to stimulate the appetites for sweet and high fat fare for children aged between 6 and 13 years old.

The children involved in the study had a greater desire for sweet and fatty foods after viewing the junk-food advertisements compared to days when they watched advertisements for toys. This was especially true for those children who watched a lot of television (defined in the study as over 21 hours a week).

While children wanted more high carbohydrate, high fat foods after watching junk food advertisements, the effects of the advertisements were modest. The researchers argued that in real life, a lot of other factors like parents’ willingness to buy those junk foods could affect the choice of food for the children.

Exposure to television food commercials would enhance high television viewers' preferences for branded foods and increased reported preferences for all food items (branded and unbranded) relative to the low television viewers, according to the researchers.

Children nowadays watch television not only at home but also on their computers as well as mobile phones, which can add up to a lot of hours. There is no doubt that parents should limit the television time of their children, but of course with some help. This is because parents alone cannot counter the food companies who spend huge amount (about $2 billion) every year on fun and irresistible advertisements aiming at kids.

Perhaps it is time for legislation and any relevant authorities to step in!

How Is Waistline Linked To Stroke?

Cerebrovascular disease is a group of brain dysfunctions related to disease of the blood vessels supplying the brain, with hypertension (high blood pressure) being the most important cause. Results of cerebrovascular disease can include a stroke, or occasionally a hemorrhagic stroke.

In Taiwan, cerebrovascular disease ranked third in the 10 leading causes of death, showing stroke could be the immense threat for the health of Taiwanese.

Scientists have found the link between waistline and heart disease. But how about stroke, does it also has some connection with the waistline?

According to a study conducted by the Millennium Health Foundation (MHF) in Taiwan, a one-centimeter increase in waistline raises the likelihood of getting a minor stroke by 2 percent.

Minor stroke, also known as transient ischemic attack (TIA), is a condition showing stroke-like symptoms that generally last for just a few minutes and do not cause any lasting impairment. TIA is, however, a warning sign of possible serious and disabling strokes. Research showed that about one in 20 people who have a TIA will have a major stroke within a few days and one in 10 will have one within 3 months.

From the data collected and released in 2010 by MHF, among 40 percent of the people whose waistlines exceeded the standard range, 70 percent of men and 60 percent of women, had abnormal blood pressure that could possibly lead to stroke. Such result showed the existence of a strong positive correlation between waistline and possibility of getting a minor stroke.

When people enter middle age, they will have their waistline increased by around 10 cm on average, the increase in probability of suffering a minor stroke will therefore amount to 20 percent. Once a person suffers a minor stroke, the chances that he or she would get a severe stroke afterwards is 10 times that of a person without a prior minor stroke.

In order to prevent stroke, MHF suggests people should limit their waistlines to a maximum of 90 cm for males and 80 cm for females.

Another Way To Control Weight

Overweight and obesity are big headache for health experts around the world as these 2 conditions will likely raise a person’s risk of getting diabetes, high cholesterol, hypertension (high blood pressure), and eventually lead to heart disease or stroke. The medical cost involved can be a heavy burden for the governments.

In order to control body weight, one should watch the amount of food he or she eats. Numerous studies have looked at how the portion size can affect on the amount people eat. A new study, conducted by researchers from University of Utah, Salt Lake City, examined at how the bite size will influence the quantities ingested.

In their paper published in July 2011 in the ‘Journal of Consumer Research’, they argued that bigger bites lead to eating less, but only in restaurant settings.

The study was carried out in a popular Italian restaurant in the South-Western United States. 2 sizes of forks were used to manipulate bite sizes: a larger fork that held 20 percent more food than the fork usually used in the restaurant, and a smaller fork that held 20 percent less than the usual one. It was found that diners who used large forks ate less than those who used small forks.

Tables were furnished with either large fork or small fork over 2 lunches and 2 dinners in the restaurant. Servers, including one of the study's researchers, took customers' orders, and weighed the full plate of food that they had ordered before serving it to them.

Each plate was attached with a small sticky note written with details including weight and other information. At the end of the meal, every plate was brought back to the kitchen and weighed again. The results showed that diners who used the bigger fork ate less food than those who used the smaller fork.

Such theory, however, only worked in a restaurant setting. In another study conducted in the laboratory using also Italian food, researchers found that people who used big forks actually eat more. Hence, the study concluded that there are different motivations when people eat in a restaurant or a laboratory.

If you wish to control the amount you eat, perhaps you should ask for or simply bring along a big fork the next time you visit an Italian restaurant!

Can Olive Oil Prevent Stroke?

Olive oil is known to benefit heart disease patients.

Some clinical trials have found that Mediterranean diet, with olive oil as key ingredient, helps control some risk factors for heart disease, including high blood pressure, abdominal obesity and elevated levels of LDL (bad) cholesterol. Besides olive oil, Mediterranean diet also includes plenty of fruits and vegetables, whole grains, fish and moderate amounts of red wine. High olive oil intake is also linked to a lower risk of heart attack, and a longer lifespan among heart attack patients.

Recently, researchers from the National Institute of Health and Medical Research in Bordeaux, France even suggested that older people who ate olive oil have a lower risk of stroke than those who did not. Their paper was published on June 15, 2011 in ‘Neurology’, the medical journal of the American Academy of Neurology.

They followed 7,625 French people who aged 65 and above from 3 cities (Bordeaux, Dijon and Montpellier) for a period of 5 years. The participants were divided into groups according to their use of olive oil, ranging from people who did not use it at all to those who used it in dressing, cooking and on bread (classified as ‘intensive’).

During the period of study, there were 148 strokes. Those intensive users suffered stroke at a rate of 0.3 percent per year, comparing with just over 0.5 percent among non-users and 0.4 percent among moderate users.

After adjusting for factors like body weight, physical activity and overall diet, the risk of stroke for ‘intensive’ olive oil users were found to have 41 percent lower than that of those who never ate olive oil.

Based on the findings, it seemed that a new set of dietary recommendation should be issued to prevent stroke in people who are 65 and above. Olive oil can be an inexpensive and easy way to help older people prevent from getting stroke.

People should choose olive oil and other unsaturated fats over saturated fats that are found largely in meats and dairy and trans fats that were found in some processed foods such as crackers, cookies and chips.

Why People Have Hypertension?

Hypertension, more commonly known as high blood pressure, could lead to hardening of arteries (atherosclerosis) and development of heart failure. That is why it has long been regarded as a major risk factor for heart disease. According to World Health Organization (WHO), around a billion people worldwide, including more than 200 million Chinese, suffer from hypertension.

When the cause of hypertension can be identified, the condition is called secondary hypertension. Kidney disease is the highest risk factor for this type of hypertension. For majority of the hypertensive patients, the causes are not known, though several factors including smoking, high salt intake, stress, sedentary lifestyle, overweight or obese, high alcohol consumption, aging and genetics are believed to play an important role. This kind of hypertension is known as essential hypertension.

Recently, researchers from Beijing Chaoyang Hospital’s Cardiology Center identified a common virus known as human cytomegalovirus (HCMV) that could be responsible for causing hypertension. HCMV infects most adults but is repressed by the body’s immune system and rarely causes any symptoms. Their findings, which linked HCMV to essential hypertension, were published in August 2011 in the medical journal ‘Circulation’.

Such findings might present a new strategy for preventing and treating cardiovascular disease. However, the researchers pointed out that their research was still in its early stage and more tests with a wider scope of patients should be carried out. Once conclusive evidence of the relationship is obtained, better medical vaccines and remedies for hypertension could then be made available to treat millions of patients around the world.

Another recent study conducted by the Tulane University School of Public Health and Tropical Medicine in New Orleans found that hypertension plays a part in 2.3 million cardiovascular deaths in China each year. Among these victims, 1.3 million were premature deaths. This means that victims died before the age of 72 in men and 75 in women, the average lifespan in China in 2005.

What Are The Causes of Preeclampsia?

Preeclampsia is a medical condition in which a pregnant woman, who has previously had normal blood pressure, develops hypertension (high blood pressure) and has significantly high amount of protein in her urine. If this condition is not treated, it could lead to serious and even fatal complications for both the mother and the baby.

When one has preeclampsia, the only cure is delivery of baby. However, if this woman were diagnosed with the condition too early in the pregnancy, she and her doctor would face a dilemma. The baby needs more time to mature but the mother needs to have delivery to avoid serious complications to her and her baby.

Even if the mother and the baby survive, the mother could later have a higher risk of high blood pressure, heart disease, stroke and diabetes. Meanwhile, the baby is often born prematurely and can suffer complications later in life.

Researchers from Britain's Cambridge and Nottingham Universities announced that they have discovered a mechanism that raises blood pressure in preeclampsia and argued that their work might help the search for new drugs for hypertension. They also believed that they had deciphered the first step in the main process that controls blood pressure: release of a hormone known as angiotensin, from its source protein, angiotensinogen. Their findings were published in the journal ‘Nature’ in October 2010.

Drugs currently used to treat high blood pressure include ACE inhibitors that block the production of angiotensin or angiotensin receptor blockers (ARB), which prevents angiotensin from taking effect in the body once it is released. These drugs work well for standard hypertension but the pregnant women could not take these drugs because they are potentially dangerous to the developing baby.

The study, primarily focused on preeclampsia, also opened new leads for future research into the causes of hypertension in general. According to the World Health Organization (WHO), hypertension itself is the biggest risk factor for causes of death worldwide. Hypertension is also a risk factor for heart disease.

The cost of treating pregnant women with preeclampsia is estimated to be $45 billion a year in the United States, Europe, Asia, Australia and New Zealand. An estimated 75,000 women in developing countries die of it each year.

Chocolate Might Help You Lower Your Cholesterol!

Who does not like chocolate? People, especially ladies, tend to eat more chocolate when they were in bad mood. But many reports had linked eating chocolate to weight gain that might lead to many medical disorders including diabetes, heart disease, high blood pressure, and stroke.

In a paper published on May 26, 2010 in the American Journal of Clinical Nutrition, researchers from the Chinese Academy of Medical Sciences and Peking Union Medical College in Beijing argued that eating chocolate could help reduce the cholesterol levels. Their theory, however, only applied to people already had risk factors for heart disease and who consumed in modest amounts.

After analyzing 8 trials involving 215 people, they found that eating cocoa would reduce levels of low-density lipoprotein (LDL) or bad cholesterol by about 6 mg/dL and cut the total cholesterol by the same amount. Further analysis showed that only people who ate small amounts of cocoa (an amount containing 260 milligrams of polyphenols or less) had their cholesterol levels lowered, and no effect was shown in people who ate more.

Polyphenols are antioxidant compounds found in fruits, vegetables, chocolate and red wine. A 1.25-ounce bar of milk chocolate contains about 300 milligrams of polyphenols.

While healthy people did not benefit from consuming cocoa, people with heart disease risk factors like diabetes had their LDL cholesterol and total cholesterol level reduced by around 8 mg/dL each.

However, researchers suggested more rigorous randomized trials with longer follow-up should be carried out in future research so as to resolve the uncertainty about the clinical effectiveness.

In fact, several studies suggesting that chocolate might be good for the health had been conducted before. A study on 19,300 people, which was released in March 2010, suggested that people who consumed the most chocolate had lower blood pressure and were less likely to suffer stroke or heart attach over the next 10 years.

Is Video Game Really Bad For Children?

Video game, together with other screen-based entertainments like TV and DVD watching, as well as leisure time computer use, has long been accused as one of the culprits that cause children obesity.

Does this mean that children should be totally banned from playing video games? Researchers from Baylor College of Medicine might have a different perspective, as they believed video games could be used to encourage kids to eat healthier foods.

Their study, which was conducted in the United States, found that children who played certain video games increased the amount of fruit and vegetables they ate each day by around one serving. In the United States, nearly one in five 6- to 19-year-olds is obese. The findings were published on December 7, 2010 in the ‘American Journal of Preventive Medicine’.

The 2 video games used in the study were "Escape from Diab” and “Nanoswarm" designed by Archimage to change diet and physical activity behaviors to reduce the risk of becoming obese and diabetic. Archimage is a Houston-based visual arts studio using its experience in computer-based architecture to specialize in serious video game development for the medial research community.

“Escape from Diab” and “Nanoswarm” were designed as epic video game adventures that are comparable to commercial quality video games. A broad diversity of behavior change procedures was incorporated into the games, which can really motivate players to substantially improve diet behaviors.

Obese children are more likely to grow up to be obese adults, to suffer from many chronic diseases including diabetes, heart disease, hypertension (high blood pressure), stroke and fatty liver disease, and to die prematurely of any cause, as shown by numerous studies.

The finding is definitely a useful step towards fighting childhood obesity because increasing intake of fruit and vegetables could reduce the risk of obesity.

But, researchers also pointed out that while there was increased intake of health foods, children still failed to consume the minimum daily amount of fruit and vegetables recommended by doctors. What worrying them most is that children did not get enough physical exercise. According to health professionals, children should eat 5 servings a day of fruit or vegetables and get an hour of moderate to vigorous exercise.

Though serious video games hold promise, the researchers still felt that their effectiveness and mechanisms of change among youth need to be more thoroughly investigated.

Eat Less Fructose To Prevent Hypertension!

Dessert is usually a sweet course of dish served at the end of a meal. It includes cake, cookie, gelatin, pastry, ice cream, pie, and candy. Dessert is not only liked by children but also favored by many adults especially females.

Besides dessert, many of our daily diet can also be laden with excessive sugar. For instance, sugary or soda drinks are popular among teenagers and many young adults. Most of these sweetened drinks contained the popular high-fructose corn syrup (sometimes called corn sugar). Fructose can be found naturally in fruit and table sugar and that is why it is also called fruit sugar.

Well, lovers of sugary drinks and sugar-laden foods should pay attention to results of a study conducted by scientists from the United States, who reported that consuming a lot of foods and drinks sweetened with fructose might significantly increase the risk of developing hypertension (high blood pressure).

The study was published on July 1, 2010 in the ‘Journal of the American Society of Nephrology’ by researchers from the University of Colorado Health Sciences Center in Denver. They found increased rates of borderline high blood pressure for people who consumed at least 74 grams of fructose a day (about 4 bottles of soda).

American Heart Association (AHA) also warned that having too much sugar of any kind can cause people gain weight and this could in turn lead to diabetes, heart disease and stroke.

While scientists have yet to find out the exact reason why fructose would raise blood pressure, some experts suspected that fructose has the potential to reduce production of nitric oxide within the blood vessels.

Nitric oxide, which is known to relax the vessel, is supposed to lower blood pressure. But fructose reduces the production of nitric oxide and makes it difficult for the vessels to relax and dilate.

Meanwhile, fructose also raises uric acid in the blood that could raise blood pressure. Fructose can signal the kidneys to 'hold onto' more salt, and that can contribute to high blood pressure.

What Would Heart Disease Cost United States 20 Years Later?

Most people are aware that heart disease is a chronic disease and the cost of treating it can never be cheap. When the condition of a heart disease patient is serious enough that it cannot no longer be treated by medication alone, he or she might need to undergo heart by-pass surgery or even heart transplant. Though advancement of technology has reduced the medical cost substantially, the amount of money that patients need to pay is still considered huge for most people.

Heart disease is the number one cause of death in most developed countries including United States, where one in 3 people has some form of heart disease. Every year, 17 percent of the cost of medical care, which is about US$273 billion, is meant for heart disease.

A study published on January 24, 2011 in ‘Circulation’, a journal of the American Heart Association (AHA) estimated that the cost of treating heart disease in United States are expected to triple to US$818 billion per year by 2030.

Based on the current disease rates, an expert panel of AHA expanded the cost according to projections from United States census data about approaching shifts in the population. The researchers also assumed that there would be no new discoveries made between now and 2030 to stop the tide of heart disease.

As revealed by the panel, 36.9 percent of Americans have some form of cardiovascular disease such as high blood pressure, coronary heart disease, heart failure or stroke presently. The number of people affected would increase to 116 million or 40.5 percent. Patients with stroke and heart failure are expected to increase the most by about 25 percent.

Most heart disease, according to AHA, is preventable if people can stick to healthy diet and adequate exercises. Unfortunately, many people do not seem to follow such advice. Meanwhile many heart disease patients do not take their medications as directed or drugs are not optimally prescribed to them. All these can further raise the cost of treatment.

Women Benefit More In Certain Heart Disease Treatment!

Heart failure is a condition in which heart is unable to pump blood at an adequate rate or in adequate volume. In serious cases, heart failure patients could lose their life with cessation of heartbeat.

There are numerous reasons why one might develop heart failure, which can be sudden or happen gradually over a periods of time. Some common causes are heart attack, high blood pressure, defective valves in the heart, cardiomyopathies (diseases of the heart muscle), too much alcohol, and congenital conditions that one is born with.

Besides taking right mix of medications, heart failure patients could have their condition reversed if the heart valve is repaired or fast heart rhythm is controlled. In some cases, certain devices are used to help the heart beat and contract properly. For example, cardiac resynchronization therapy with defibrillator (CRT-D), which is a form of therapy for congestive heart failure caused by dilated cardiomyopathy, have been found to have remarkable benefits on appropriately selected patients with heart failure.

CRT-D can help guard against sudden death from irregular heart rhythm by using a specialized pacemaker to re-coordinate the action of the right and left ventricles in patients with heart failure. It can also help strengthen pumping action in patients with heart damage.

Researchers from the University of Rochester pointed out in their findings that CRT-D works twice as well in women. Their study, which was published on February 7, 2011 in the ‘Journal of the American College of Cardiology’, found that when using CRT-D, there was a 70 percent reduction in heart failure in women compared a 35 percent drop in men.

This is probably the first time in history of heart disease research that has credited a certain type of treatment that is more effective in women than in men. In the past cardiac studies, men and women generally received similar benefit from preventive medical therapy.

According to researchers, CRT-D works better in women because women tend to suffer from a different type of heart disease than men. The male participants in the study were more likely to have coronary heart disease while the female participants were more likely to suffer from non-ischemic heart disease.

Coronary artery disease, which is also known as ischemic heart disease, is a condition in which narrowed vessels restrict blood flow to the heart. Non-ischemic heart disease, on the other hand, is one that involves more generalized scarring of heart tissue.

Let Garlic Help You Lower Hypertension!

While garlic is widely used as a seasoning or condiment, it has also been used as a remedy for infections, digestive disorders and fungal infections. In fact, traditional Indian Ayurvedic medicine practitioners have been using garlic to prevent high blood pressure for centuries. Meanwhile, many past studies also linked it to prevention of cancer and heart disease, and reduction of blood sugar.

A 12-week trial involving 50 patients that was conducted by Australian researchers from University of Adelaide reported that people with hypertension (high blood pressure) who took 4 capsules a day of a aged garlic extract had their systolic blood pressure reduced by around 10 mmHg, as compared with those who were given a placebo. The findings were published in October 2010 in the scientific journal ‘Maturitas’.

A placebo is a sham or simulated medical intervention that is commonly used in medical research. It is given as control treatments and can be inert tablets, sham surgery and other procedures based on false information.

However, the researchers pointed out that garlic, if it is taken in any other way, for instance, raw, fresh or in powdered form, does not have the same effect. When fresh garlic is cooked, its ingredient that is responsible for lowering blood pressure simply disappeared.

Though this was not the first study to examine the beneficial property of garlic, it was the first study to assess the impact of aged garlic extract that was evaluated as an additional treatment to other high blood pressure drugs, as claimed by the researchers.

Hypertension is a risk factor for coronary heart disease, stroke, heart failure, kidney failure, peripheral vascular disease and many other medical conditions. Globally, about 1 billion people have hypertension, which also affects about 1 in 3 adults in the United States. If hypertensive patients can have their blood pressure normalized, the risk of getting heart disease and stroke could be reduced.

Nevertheless, as garlic has blood-thinning effect and might interact with many drugs, it is advisable for patients to seek advice from qualified health practitioners or doctors before taking any garlic supplements.

If You Quit Smoking, Others Will Just Follow!

Smoking is not a desirable habit since it will not only put smokers but also place non-smokers through second smoke at higher risk of getting many diseases including cancer, heart disease, hypertension (high blood pressure), and stroke. That is why many countries around the world including China have banned smoking in the public areas.

The influence among the social network could, however, also help smokers give up smoking immediately.

According to a paper published in the May 22, 2008 edition of the ‘New England Journal of Medicine’, if a person quit smoking, then this person’s spouse, best friends, colleagues and even the surrounding people who are not known very well to this person will just follow suit.

Researchers from Harvard Medical School analyzed relationships among some 12,000 people over 3 decades and found that a steady decrease in smoking over that period occurred in clusters. So if there is a change in the zeitgeist of this social network, the whole group of people who are connected but who might not know each other all quit together.

Zeitgeist means the spirit of the times or the spirit of the age. It is the general cultural, intellectual, ethical, spiritual within a specific group, along with the general ambiance, morals, socio-cultural direction, and mood associated with an era.

Researchers reconstructed the social networks of 12,067 individuals during a period between 1971 and 2003, recording major life changes such as marriage, death and divorce.

All the study participants also listed contact information for close friends, work colleagues and neighbors. Interestingly, many of those friends and colleagues had also joined the study. This enabled the researchers to observe a total of 53,228 families, social or professional relationships. Their findings showed that people quit smoking in clusters.

Over the 30-year period, the average size of each particular cluster of smokers within the entire network remains about the same but there are fewer and fewer of these clusters left as time goes on.
