It Is Food Choice That Make You Fat!

What you eat is what you get! Unhealthy eating can cause people to develop chronic diseases including Type-2 diabetes, high cholesterol, heart disease and stroke.

Many people believe eating less and exercise more can achieve good health! But in reality, this seems to be too simplistic because researchers from the Harvard School of Public Health found that slight changes in eating habits, like eating an extra serving of potato chips or fries each day, could raise a person’s weight over the years.

After examining data on diet and lifestyle of 3 large studies including more than 120,000 nurses and health professionals from around the United States over a period of 20 years, the researchers argued that overall food choice appears to have the strongest link to how much a person gains weight.

While the United Nations praising potato as a good source of Vitamin-C, several B Vitamins and Minerals, including iron, potassium, phosphorus and magnesium, the researchers reported on June 22, 2011 in the ‘New England Journal of Medicine’ that people who ate an extra serving of French fries every day gained an average of 1.5 kilos over a 4-year period. Those who consumed on an extra serving of potato chips daily gained an average of 770 grams every 4 years, and an extra serving of potatoes prepared in any non-chip form was found to contribute to an average weight gain of 590 grams over 4 years.

Similar results were seen in people who consumed extra sugary drinks (0.45 kilos) and unprocessed meat (0.43 kilos) and processed meat (0.42 kilos).

On the other hand, people ate more of certain foods like yoghurt, vegetables, fruits and whole grains, did not gain weight. Over the period of 4 year, people who ate an extra serving of vegetables each day lose 0.1 kilos. Similar results were discovered in people who ate extra serving of yoghurt (0.37 kilos), fruit (0.21 kilos) and nuts (0.26 kilos).

In conclusion, the study found that quality of food is more important than quantity to prevent long-term weight gain, and that small lifestyle changes did make the difference between staying slim and becoming overweight.

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!

Weight Loss Could Help Ward Off Diabetes!

Insulin resistance sometimes combined with absolute insulin deficiency cause Type-2 diabetes to develop. Insulin resistance is a condition in which cells cannot use insulin properly. Type-1 and gestational diabetes are the other two main types of diabetes.

Of the many risk factors identified for Type-2 diabetes, obesity, sedentary lifestyle and unhealthy eating habits are somewhat associated with weight gain. High cholesterol, high blood pressure, family history and genetics, and increased age can also raise the likelihood of getting Type-2 diabetes.

A study conducted by researchers from Johns Hopkins University in Baltimore found that Type-2 diabetes could possibly be reversed if obese diabetics go for a weight-loss surgery. Their findings published on August 16, 2010 in the medical journal, ‘Archives of Surgery’ indicated that 75 percent of obese diabetics who had undergone weight-loss surgery (bariatric surgery) could actually stop taking diabetes medications within 6 months of their operation.

Researchers carried out one of the few studies examining how surgery can affect health cost in Type-2 diabetics by analyzing insurance claims data from 2,235 patients who underwent bariatric surgery during a 4-year period.

The results showed that among the diabetic patients who had bariatric surgery, only one quarter were still taking diabetes drugs 6 months later. In fact, the number kept falling: 12 months after the surgery, less than 20 percent of patients were taking medications and 24 months after surgery, only 15 percent were still been prescribed with medications.

It has long been known that diabetes and obesity can rarely be reversed once they are developed. This is definitely good news for obese Type-2 diabetics since the need for chronic medications can be eliminated and the overall medical cost could be reduced too. More importantly, this can greatly reduce the risk of developing heart considering the fact that diabetes is a risk factor for heart disease.

Nevertheless, it seems that bariatric surgery would be the only solution that most of the obese diabetics can opt for in order to substantially reverse both obesity and Type-2 diabetes, at least for the time being until experts can find a successful non-surgical methods.

Why Mango Should Be In Your Diet List?

Who wants to be overweight? If this question is asked, it is quite sure that no one would raise the hand and say yes. The reason is simple. Overweight and obesity would bring along many undesired medical disorders including heart disease, high blood pressure (hypertension), stroke and Type-2 diabetes.

Overweight people, with a few exceptions, would try every means to lose the extra weight they have. They will either adopt weight management program that incorporates exercise and diet or take some products that could help lose weight.

Among the many weight-loss products available, researchers from Cameroon's University of Yaounde found a product, originated from West Africa, which could help overweight or obese people lose weight and stabilize cholesterol levels. It is a fruit called irvingia gabonensis, also known as African mango. Their findings were published on March 25, 2009 in ‘Lipids in Health and Disease’.

In the study, a test group of 102 overweight adults was given either extracts of the fruit or a placebo 2 times a day over a period of 10 weeks. The individuals’ diet and levels of activity were not changed.

At the end of 10 weeks, people who consumed fruit extract had a significant weight loss, a total of 12.5 kilos (or 28 pounds), while those who were in the placebo group showed no change in their weight. Participants taking the extract also had reduction in LDL (bad) cholesterol and nominal improvements in their blood sugar levels.

According to the researchers, the fruit extract helps bodies become more sensitive to lepitin, which is a hormone excreted by the body to control fat storage, especially in the midsection. As many overweight or obese people are resistant to lepitin, the fruit extract helps their bodies to overcome such resistance thus resulting in weight loss.

While some side effects like excess gas, sleep problems and headaches were reported among some participants in the fruit extract group, such side effects were also reported similarly in rate among participants in the placebo group.

Though scientists have suspected that Africa mango has the ability to help trim excess weight, this was the very first clinical study showing its true effects. It is hoped that the new findings would inspire some larger clinical studies to be implemented to further confirm the benefits derived.

What Cause The Diabetes Epidemic in Southeast Asia?

Junk food refers to food that is high in calories but low in nutritional content, according to the definition by Merriam-Webster. For decades, health experts have blamed junk food for causing obesity epidemic, especially among the youngsters.

On July 7, 2010, Australian and Vietnamese researchers from Sydney's Garvan Institute of Medical Research warned that the growing popularity of Western junk food is the culprit responding for the diabetes boom across Southeast Asia.

The study showed that about 11 percent of men and 12 percent of women in Vietnam’s Ho Chi Minh City had Type-2 diabetes without even realizing it, in addition to the 4 percent of people who had already been diagnosed with diabetes. Their findings were based on testing a random sample of more than 2,000 people including 721 men and 1,421 women.

Being the most common form of diabetes, Type-2 diabetes is a medical disorder that is caused by high level of sugar and fat in the diet and inadequate exercise. If a patient with Type-2 diabetes were not getting timely treatment, he or she would face a higher risk of developing many complications including heart disease, kidney failure, limb amputation and vision loss.

In recent years, dietary patterns have been altered dramatically in Vietnam, particularly in cities that have become more westernized. Fast food outlets are available everywhere. This is rather sad because while developing countries are facing hunger and poverty, they are also affected by Western lifestyle diseases without adequate health resources to deal with.

Since similar study carried out in Thailand supported the link, the researchers are confident that their findings could be extrapolated to other parts of Southeast Asia including Cambodia, Laos, Malaysia and Singapore.

Meanwhile, the researchers have also developed a simple risk assessment for diabetes, using blood pressure and waist-to-hip ratio. Hopefully, this can help doctors detect those who are most likely to have diabetes.

An Interesting Proposal For Fast Food Restaurants!

Health experts have long regarded fast food as unhealthy because its high salt and high fat contents are responsible for causing regular patrons of fast food restaurants become overweight and obese.

As we are all aware, overweight or obesity is the root of many other complications including high cholesterol, Type-2 diabetes, heart disease, high blood pressure and stroke. Therefore, many fast food restaurants have already started to alter their recipes making them looked “less unhealthy”. For example, some have lowered the salt contents while others might add in more vegetables.

Lately, health professionals had proposed an interesting idea to the fast food restaurants. Researchers from the National Heart and Lung Institute at the Imperial College London suggested in the April 2010’s issue of the American Journal of Cardiology that fast food restaurants should give away free cholesterol-busting statins drugs together with their burgers and fries to their customers as a way to offset the possible heart disease risks caused by the food.

Statins, a family of cholesterol-lowering medications including Crestor and Lipitor, are currently available only by prescription. They have been famous of its ability to lower the amount of unhealthy LDL cholesterol (bad cholesterol) in the blood. Numerous studies have also shown that statins are very effective in preventing a heart attack.

According to the researchers, taking a statin tablet could help reduce the increased risk of developing heart disease because of the high fat content in a medium-sized cheeseburger and a small milkshake.

I am sure many of us would not find the new idea convincing. Even some health professionals are skeptical about the proposal and they caution that one should not take the suggestion literally.

In defending their proposal, the researchers used car seat belt as metaphor. They argued that people are advised to fasten their seat belts while traveling in car because of the increased risks to their health when driving or sitting in a car. Likewise, some people do eat unhealthily so they should be given some drugs to offset the possible bad effects.

Nevertheless, they did admit that statins could not eliminate all the unhealthy effects of burgers and fries. Therefore, the best way to stay healthy is still to avoid fatty food.

If You Do Not Want To Have Stroke, Start Walking

Stroke is a disease that affects the arteries leading to and within the brain. It is the third largest cause of death in the United States. A stroke occurs when a blood vessel to the brain is either blocked or bursts (hemorrhage).

A person who has a stroke might not able to move one or more limbs on one side of the body, to understand or formulate speech, or to see one side of the visual field. Being a medical emergency, stroke can cause permanent neurological damage, complications and even death.

Obviously, one should strive to keep stroke away!

A study conducted by researchers from Harvard School of Public Health in Boston revealed that women can lower their stroke risk by walking. They reported on April 6, 2010 in the American Heart Association (AHF) journal “Stroke” that women who walked briskly had a 37 percent lower risk of stroke than those who did not walk, and women who walked at least 2 hours a week at any pace had a 30 percent lower risk.

Previous studies have already shown that physical activity reduces the likelihood of getting stroke, the new study looked at what kind of exercise might be most beneficial for women.

About 39,000 female health workers aged 45 or older enrolled in the Women’s Health Study were involved in the study. The women were periodically asked about their physical activity. During the 12 years of follow-up, 579 of them had stroke. Age, aspirin use, smoking and other factors that could affect stroke risk were taken into account.

While the study also examined vigorous activities such as running, swimming and biking in addition to walking, no link between these vigorous activities and a reduced stroke risk was found. According to the researchers, it is possible that there were insufficient number of women in that group to show a difference, and it is also likely that moderate activity is better at lowering blood pressure, which is a strong risk factor for stroke.

Besides high blood pressure, risk factors for stroke include heart disease, Type-2 diabetes, and obesity.

Why Long-Term Weight Loss Is Not Desirable?

The obesity epidemic has been a pressing issue for the world as overweight or obesity would bring about many medical disorders including diabetes, heart disease, high blood pressure and stroke. The consequence is huge amount of health expenses would be required to cover these diseases.

Naturally, no one would like being overweight or obese and if someone makes a statement like “weight loss is always beneficial, and weight gain is always harmful”, I am quite certain that not many people would raise their hands to object.

However, a paper published in the International Journal of Obesity on September 7, 2010 by researchers from Kyungpook National University in Daegu in South Korea revealed that long-term weight loss might release into the blood industrial pollutants, which is linked to diseases such as Type-2 diabetes, coronary heart disease, hypertension, periodontal disease and rheumatoid arthritis. These hazardous compounds are normally stored in the fatty tissues, but when fat breaks down during weight loss, they get into the blood stream and can reach vital organs.

After studying concentrations of 7 such compounds in blood of 1,099 participants in the United States, they found that those who lost weight over 10 years had the highest concentrations of the compounds, known as persistent organic pollutants (POPs), compared to those who gained or maintained a steady weight.

The findings totally opposed to the overwhelming data showing attaining a healthy weight is good for preventing many diseases. When a study that goes against the common sense, it would naturally arouse doubts or even opposition from other health professionals.

Some of them feared that overweight or obese people might use such findings as an excuse to stop trying to reduce their weights through healthy diet and exercises, while others suggested people should figure out if the study seems sound and applies to the average population.

In fact, even the researchers themselves acknowledged that further studies are required to establish the link between long-term weight loss and health problems.

Is Vegetable Really Good for Diabetics?

According to World Health Organization (WHO), diabetes affects more than 285 millions people worldwide, of which 4 million people of them will die every year by 2010. The number could rise up to 438 millions by 2030 with the increasing obesity rate.

Type 2 diabetes, being the commonest form of diabetes, has swiftly spread from wealthy to the fast-developing countries because of the fatty, sugary diets and sedentary lifestyles.

While nutrition and exercise are important in the prevention of such disease, the dispute on ‘which foods work best and why’ continues. This is because only few good quality studies were carried out to explore such issue.

Recently, researchers from the University of Leicester, central England found that eating more spinach and other green leafy vegetables could actually reduce the risk of Type-2 diabetes. Their findings were published in the British Medical Journal (BMJ) on August 20, 2010.

6 studies involving 220,000 people were reviewed to explore the link between fruit and vegetable consumption and Type-2 diabetes. The results showed that eating one and a half extra servings (106 gm) of green leafy vegetables reduce the risk of diabetes by 14 percent, while eating more fruit and vegetables combined had negligible impact.

Researchers could not explain why leafy vegetables have such protective effect, though they suspected it is probably because of the high antioxidants such as Vitamin C and magnesium found in green leafy vegetables.

As such, they suggested more investigation should be carried out to confirm their findings. Other health experts also felt that it was too early to isolate green leafy vegetables and regard them alone as a way to reduce the risk of getting Type-2 diabetes.

Meanwhile, the researchers as well as other experts in the field urged people to continue consuming 5 portions of fruit and vegetables a day, which would benefit people in the prevention heart disease, stroke, some cancers and obesity as well as Type-2 diabetes.

The National Diet Nutrition Survey showed that, although fruit and vegetable intake has increased over the past decade, only a third of men and women eat the recommended five-a-day in 2008/09.

Would Vitamin Help Diabetics?

For people who are unable to get adequate amount of vitamins and minerals from their diet, taking vitamin supplements could be a feasible alternative to help them meet their nutrition requirements. The elderly, strict vegetarians, people on low-calorie diets and those that are malnourished are some good examples of this type of people.

How about diabetics? Would vitamin help control their condition? Most health organizations associated with diabetes do not advocate using vitamins. In fact, they usually warn against using large doses of vitamins or supplements, which could possibly cause adverse side effects.

In April 28, 2010 edition of the Journal of the American Medical Association (JAMA), researchers from the University of Western Ontario and the Robarts Research Institute in London, Ontario reported that patients with diabetic nephropathy would suffer rapid deterioration of the kidneys if treated with high doses of Vitamin B. Moreover, these patients are likely to face a higher risk of heart attack and stroke than patients who took a placebo.

Diabetic nephropathy is a progressive kidney disease because of longstanding diabetes mellitus, and it is a prime indication for dialysis in many Western countries. Even with the many treatments available right now, about 40 percent of the 21 million Americans who have diabetes still develop diabetic nephropathy.

Prior observational studies have shown that there is an association between high concentrations of plasma total homocysteine and the risk of developing diabetic nephropathy, retinopathy, and vascular diseases, including myocardial infarction and stroke. B-Vitamin therapy using folic acid, Vitamin-B6 and Vitamin-B12 is known to be capable of lowering the plasma concentration of homocysteine.

With an aim to developing a new approach to treatment, the researchers conducted a study to see if B-Vitamin therapy would actually slow progression of diabetic nephropathy and prevent vascular events in 238 patients with Type-1 or Type-2 diabetes. Meanwhile, the placebo-controlled trial was carried out at 5 university medical centers in Canada between May 2001 and July 2007.

Patients were prescribed with single tablet of B-Vitamins with folic acid (2.5 mg/d), Vitamin-B6 (25 mg/d), and Vitamin-B12 (1 mg/d), or matching placebo. After an average period of 31.9 months, patients with Vitamin-B were found to have a faster rate of reduction of kidney filtering and so the kidney function, as compared with those on a placebo course. For patients with the diabetic nephropathy, the risk of heart attack and stroke were also higher than those who took placebo.

Women Should Walk to Lower Their Stroke Risk!

Having adequate physical activity such as brisk walking can help prevent heart disease. The recommendation by the American Heart Association for adults is to do 2-and-a-half hours a week of moderate-intensity or 75 minutes a week of vigorous aerobic activity or a combination of both.

Recently, a group of researchers from Harvard School of Public Health in Boston found that women could actually reduce their risk of stroke by walking. Published on April 6, 2010 in the American Heart Association journal Stroke, the findings reported that women who said they walked briskly had a 37 percent lower risk of stroke than those who did not walk. For those women who walked at least 2 hours a week at any pace had a 30 percent lower risk of stroke.

Previous studies have already reported physical activity decreases stroke risk. For example, a study by the Harvard School of Public Health reported in 2000 in the Journal of the American Medical Association that physical activity, including walking, provided a significant reduction in stroke risk. The new study, however, took a step forward to focus on the kind of exercise that might be most beneficial for women.

About 39,000 female health workers who were 45 and older were involved in the study known as Women’s Health Study. The women were asked about their physical activity at the start of the study (1992-1995) and periodically reported their activities thereafter. During the 12-year period, it was found that 579 of them had stroke.

In addition to walking, the researchers also examined other vigorous activities such as running, swimming and biking. However, no link was found between those vigorous activities and a reduced stroke risk.

This could be due to insufficient number of women in that group to show a difference or moderate activity could be better at lowering blood pressure, as explained by the researchers.

While the study was observational with self-reported data, the research team did control well of other risk factors including age, aspirin use and smoking that could affect stroke risk. The researchers were happy to find that moderate activities are powerfully effective in cutting the stroke risk.

Stroke is the third leading cause of death in the United States, after heart disease and cancer. Besides high blood pressure, heart disease, Type-2 diabetes and obesity are also risk factors that could lead to stroke.

Is There A Faster Cheaper and Painless Way To Test Diabetes?

Diabetes, if not managed or treated with care, could easily lead to serious medical conditions including blindness, heart disease, high blood pressure, kidney disease, nervous system disease, stroke and amputation.

In order to diagnose whether a person is having diabetes or pre-diabetes, doctors usually use a fasting plasma glucose (FPG) test to measure blood glucose in that person who has not eaten anything for at least 8 hours. Sometimes, an oral glucose tolerance test (OGTT), which measures blood glucose after the person fasts at least 8 hours and 2 hours after the person drinks a glucose-containing beverage, might also be employed.

For diagnosis of diabetes (not for pre-diabetes), a random plasma glucose test is used. The test, also known as casual plasma glucose test, measures blood glucose of a person at any time without regarding when this person last ate.

Here comes the so-called Wrinkle Test, which is considered as a faster and cheaper method to diagnose if a person has diabetes. The Wrinkle Test can identify a disorder in the sensors on a person’s skin and was developed by researchers at the National University of Singapore (NUS) and the National University Hospital (NUH).

Carrying out the test is fairly simple. Apply a local anesthetic as cream on the fingers of the person being tested. If the skin does not wrinkle after some time, then this person must has a nerve fiber disorder that could be caused by disease like diabetes.

The results of the test are compared against a scale of between zero and 4. Zero indicates there is no wrinkling and is a sign that the constriction of blood vessels is being impaired. Studies have shown that wrinkling is caused by a constriction of blood vessels. A patient with a small nerve fiber disorder, which disrupts the constriction, would have fewer wrinkles.

Though many diseases could actually cause a disorder on the small nerve fibers on the patients’ skin, diabetes is the most important cause because almost half of the diabetic patients in Singapore suffer from some kind of the disorder.

Nevertheless, Wrinkle test is surely not the only way to identify nerve fiber disorders. In fact, nerve disorder could be diagnosed by removing a skin sample, which was then sent to laboratory for testing. And it usually takes between 1 to 2 weeks before results can be known.

Can Resistance Exercise Really Help Those With Type-2 Diabetes?

When a person is diagnosed with diabetes, his or her body would have problem making or using insulin. Insulin is required for moving glucose (blood sugar) into cells, where it is stored and later used for energy.

An estimated 24 million people in the Untied States have diabetes, with 90 percent of them are diagnosed as Type-2 diabetes, which typically develops after the age of 45. And, it could be the result of unhealthy lifestyle habits.

The glucose levels found in patients with Type-2 diabetes are high because of insulin resistance and relative insulin deficiency. Insulin resistance means that fat, liver, and muscle cells do not respond normally to insulin. As such, blood sugar does not get into cells to be stored for energy.

Once sugar fails to enter cells, abnormally high levels of sugar will accumulate in the blood stream. This will often trigger the pancreas to produce more and more insulin, but can never be enough to keep up with the body's demand.

Diabetes is already a chronic disease by itself. If it is not managed appropriately, it can surely place patients at a higher risk of developing other serious complications including heart disease, blood vessel disease, kidney failure, nerve diseases and even blindness and amputation of legs.

In September 2007, a paper published by Canadian researchers in the Annals of Internal Medicine showed that Type-2 diabetics, who exercised regularly, could have better blood-sugar control, especially if they did aerobic exercises as well as lifted weights.

According to most doctors and health experts, exercise is another powerful way to reduce blood sugar, in addition to strict diet control and medication. In general, exercise would help diabetics reduce insulin resistance by allowing cells in the body to have a higher uptake of glucose in the blood stream. This certainly would improve blood sugar control.

Besides aerobic exercise, Type-2 diabetics are advised to perform resistance training at least 3 times a week. Resistance training is one that includes exercises conducted using weights, weight machines or elastic bands. Its purpose is to improve strength by slowly and progressively overloading the muscles over a series of exercise sessions.

Nevertheless, diabetics should be aware of some risks in overdoing exercise. The most common one is patients might experience low blood sugar after drastic exercise. As such, patients should have their blood sugar checked before and after performing their exercise.

Meanwhile, patients with diabetes over long period of time, or kidney, eye or feet complications from diabetes might encounter problems when exercising. So, it is better to consult a physician before starting to engage any training program.

Is The Number of Young Diabetics Rising in Asia?

Diabetes mellitus, more often referred to as diabetes, is a condition in which the body does not produce enough or properly respond to insulin. Being a hormone produced in the pancreas, insulin has the function of enabling cells to absorb glucose and turning it into energy. When a person has diabetes, the glucose will accumulate in the blood and this will eventually lead to various complications. For instance, diabetes has been identified as a risk factor for heart disease.

There is no doubt that diabetes has turned into a global problem. It is expected that the number of victims will grow from 240 million in 2007 to 380 million in 2025.

In Europe and North America, overweight and obesity have long been thought to lead to Type-2 diabetes. However, a study, published on May 27, 2009 in the Journal of American Medical Association, reported that the number of diabetics is rising in Asia affecting those who are relatively young and less likely to be struggling with obesity, unlike in the West.

Based on the figures from the International Diabetes Federation, more than 60 percent of diabetics will reside in Asia, the fastest growing region in the world. Countries with low- and middle-income will face the hardest hit. The number of diabetics will grow from 40 million to nearly 70 million in India; 39 million to 59 million in China; and 3.8 million to 7.4 million in Bangladesh.

While the trends of diabetes could be influenced from genetic makeup and cultural differences to smoking and degrees of urbanization, the most startling result was still related to body mass and age.

Despite lower obesity rate, the waistlines of Asian population keep expanding as a result of rapid economic development, changing diets and more sedentary lifestyle. Expanding waistline is considered to be harmful to diabetes. This is because fat around the abdomen stores excess energy and releases chemicals that control metabolism and use of insulin.

Although people across Asia generally have lower body mass index (BMI), which is the ratio of weight (kg) divided by the square of height (cm), they can have a similar or even higher chance of developing diabetes, according to the study.

The Number of Diabetics Rises In Europe!

According to IDF (International Diabetes Federation), diabetes affects 246 million people worldwide and the figure is expected to rise to some 380 million by 2025.

People should never treat diabetes lightly because it could lead to fatal consequences. Diabetics might have symptoms such as frequent urination, thirst, unexpected weight loss, extreme hunger, and frequent fatigue. If the blood glucose is too high, they can develop comatose.

If the blood sugar level is not controlled effectively, diabetes can lead to blindness, neuropathy (damage to nerves), and even lower-limb amputations. Patients, who also have hypertension (high blood pressure), can have a higher chance of getting kidney failure. Meanwhile, one should not forget that diabetes has been a known risk factor for cardiovascular and heart disease, too.

A study, published on May 28, 2009 in the British Journal ‘The Lancet’, revealed that incidence of Type-1 diabetes in children aged below 5 in Europe is expected to double and those aged below 15 will increase by 70 percent by 2020 over the 2005 levels.

Based on diagnosed cases between 1989 and 203, the researchers warned that the trend will be highest in the former Communist countries of Eastern Europe. The dramatic increase could be attributed to genes as well as the modern lifestyle habits.

In general, there are 2 types of diabetes, namely Type-1 and Type-2 diabetes. Type-1 diabetes generally begins during childhood and early adolescence. The immune system destroys cells in the pancreas that make insulin, and this does cause the glucose level in the blood to rise dangerously. Insulin is the hormone, which breaks down glucose into other forms of energy.

A mix of genetic vulnerability and environmental factors, such as increases in weight and height, less exposure to early infections in childhood and delivery by caesarean, might cause such disorder, according to health experts.

On the other hand, Type-2 diabetes occurs when there is insufficient insulin or cells become insensitive to the insulin that is produced. It is closely linked to chronic obesity, resulting from sedentary lifestyles and the consumption of sugary and fatty foods. The number of Type-2 diabetics is far more than Type-1 diabetics.

How Can Recession Obesity Affect The American Children?

In 2008, a study published in the Journal of the American Medical Association (JAMA), reported that nearly 32 percent of American children were overweight and 16 percent were obese.

Meanwhile, between 1980 and 1999, the obesity rate had tripled and this no doubt had created an epidemic. Poor diet that is heavy on fat and sugar with little consumption of fruits and fresh vegetables, and lack of exercise were blamed to be responsible for such phenomenon.

Obese children not only have a higher chance of becoming obese adults but are also at a higher risk of developing heart disease, high cholesterol and Type-2 diabetes.

Now, there is another possible force, which in the opinion of researchers, will help increase the obesity rate. Researchers from Duke University argued that the prevailing economic downturn would probably put American children at risk of ‘recession obesity’.

‘Recession obesity’ is a term for unhealthy side effects of people who lose their jobs and health insurance, then drop their gym memberships, delay medical treatment, and eat cheaper but less healthy meals. As fast food is cheap and filling, its consumption is on the rise during the economic downturn. The researchers fear that parents would substitute for their children fast food, high carbohydrate and high sugar-content food for healthy food. This would surely cause an uptick in the rate of overweight children and adolescents.

After analyzing dozens of indicators, the researchers compiled the 2009 Child Well-Being Index. The index tracks how American children are faring socially, emotionally, in terms of education and health. It aims to assess how American children are faring today, comparing their current situation with the past. They also project what these children might face in the future. This year’s index includes a special report on the impact of the current recession on the American children.

Is Calorie-burning Fat Just a Myth?

Have you ever heard about “calorie-burning fat”? If not, you may wonder does it really exist or just a science fiction.

In reality, adults do have small blobs of metabolism-regulating “brown fat”, which scientists believe it exist only in babies and children. Such finding was announced in a study conducted by researchers from the Joslin Diabetes Center in Boston, Massachusetts.

The paper, published on in April 9, 2009’s issue of The New England Journal of Medicine, revealed that the brown fat or so-called good fat differs from white fat that makes up most body fat in such a way that the brown fat is active in burning calories and using energy. They also showed that the brown fat subsisted in adult humans and demonstrated, for the first time, that it is metabolically active.

According to the study, brown fat may have a role in regulating body weight metabolism. Therefore, by stimulating brown fat growth to control weight and improve glucose metabolism, the researchers believe that obesity, Type-2 diabetes and other metabolic disorders could be treated. Meanwhile, higher levels of brown fat might also help protect against obesity linked with aging.

By analyzing a database of 1,972 patients who had nuclear (PET) or X-ray (CT) imaging scans during a 3-year period for a variety of reasons, the researchers discovered that significant brown fat deposits in 7.5 percent of female patients and in over 3 percent of male patients. Most of the brown fat deposits were found in the patients' necks.

In the study, the tissue of 2 patients showing brown fat concentrations in their necks were tested and it was found that the cells had the protein UCP-1, which is unique to brown fat.

The study also found that the amount of brown fat presence depends on a variety of factors like age, glucose levels and, most importantly, level of obesity. For example, younger and thinner patients who had normal blood glucose levels had more brown fat, while brown fat was more active in cold weather as it helps in burning energy to produce heat.

It has been known that obesity, Type-2 diabetes and other disorders associated with obesity or overweight could eventually lead to heart disease. Such new discovery not only helps treat people with obesity but also helps them prevent heart disease.

Obesity Cannot Be Blamed for Bad Health?

Obesity or overweight has long been linked to medical disorders like diabetes that could eventually lead to heart disease, hypertension (high blood pressure), stroke, or kidney disease. Evidence also showed that certain types of cancer are associated with weight gain.

The evidence linking obesity to diabetes and cardiovascular disease is very strong and it is known that Type-2 diabetes seldom occurs in people who are not obese or overweight.

Based on the standard set by the World Health Organization (WHO), a person who has a body mass index (BMI) of above 25 is considered overweight and those with BMI exceeding 30 are obese. BMI is defined as weight in kilos divided by the square of height in meters.

However, not all health experts agree on the arguments mentioned above. Instead, a minority of health experts, who are termed as the obesity contrarians, argue that there is no data proving why being fat would be dangerous. To them, being obese is not as severe a threat as is thought. They felt that the obesity epidemic has been absolutely been exaggerated.

A political science professor even claimed that there is no good causal connection between obesity and bad health. According to his opinion, blaming obesity for diabetes and heart attacks is like blaming lung cancer on bad health rather than on smoking. He explained that since other factors such as diet, exercise or genetic predispositions towards diseases are harder to measure than weight.

Other skeptics also criticize the over-projection on the rise in obesity. For example, the British government warns that nearly half of the Britain’s population will be obese by 2050. The skeptics believe that these projections are not based on good evidence because those who are obese are often lumped together with those who are overweight. To them, people, who are overweight, may be perfectly healthy.

It is true that people, who are thin, can get diabetes, hypertension, stroke and even heart disease while people, who are fat, are apparently healthy. Nevertheless, until health experts could derive sound evidence to prove that obesity is definitely bad for health, there will still be some obesity contrarians out there to advocate otherwise.

Not-As-Sweet Drinks Might Prevent People From Being Obese or Overweight!

In United States, there are more than two-thirds of the population is either overweight or obese. Being obese or overweight, one is subject to a higher risk of developing heart disease, diabetes, high blood pressure (hypertension), stroke and even certain types of cancer.

With evidence that shows that sugary drinks are an important contributor to the epidemic of obesity and Type-2 diabetes in United States, nutrition experts urged soft drink makers to invent and market a new range of semi-sweet drinks that would help Americans free from reliance on sugary beverages.

A study by Harvard researchers on 90,000 women even found that women who drank more than 2 servings of sugary beverages each day had a nearly 40 percent higher risk of getting heart disease than women who rarely drank such drinks. The findings were published in the April 2009 issue of the American Journal of Clinical Nutrition.

On April 20, 2009, nutrition experts proposed a new category of reduced-calorie beverages containing no more than 1 gram of sugar per ounce. In other words, the proposed drinks contain about 50 calories, which is about 70 percent less sugar found in a typical soft drink. Furthermore, they should not have artificial sweeteners such as aspartame and saccharine.

Among the current available range of drinks, a 20-ounce (590 ml) bottle of soda contains nearly 17 teaspoons (255 ml) of sugar and 250 calories (1.05 kj).

It is hoped that with the new drinks, the present American norm could be shifted back to a lower expectation of sweetness so that people would adjust their palates, especially the younger population. Statistics show that 4 out of 5 children and 2 out of 3 adults drink sugar-sweetened beverages on any average day.

However, such proposal seem not welcome by the food and beverage makers, who blame people seldom or not exercise at all and argue that people should responsibly choose to eat snack foods.

Can Diabetes Be Prevented and Even Cured?

Type-2 diabetes is usually caused by overweight or obesity. Being a diabetic, he or she is at a much higher risk of getting high blood pressure, kidney failure, and even heart disease.

According to the statistics released by the diabetes association, nearly 57 million people in the United States are pre-diabetic and 18 million have been diagnosed with diabetes. Meanwhile, there are almost 6 million Americans, who have diabetes, but they are not aware of it. About 90 to 95 percent of diabetics are classified as Type-2 diabetes, which is closely related to obesity.

Generally, when a person is diagnosed as pre-diabetic, he or she would not really bother because technically, he or she would not be classified as diabetic just because of a slightly higher than normal blood sugar level.

A 55-year-old woman Jane (not her real name) in Dallas was diagnosed as pre-diabetic by her doctor who advised her to lose 3 kilograms through changing her lifestyle and diet. Nevertheless, this did not really alarm her even her sister had died of diabetes.

9 months later, she was confirmed having Type-2 diabetes. By then, she was shock and took the advice from her doctor seriously. On a regular basis, she exercised and her weight had slimmed down. More importantly, her blood sugar level fell back to normal and healthy range without taking any diabetes medications.

In fact, the medical community is expressing its interest in diabetics like Jane who manage to get their blood sugar under control, either escaping the need for drugs or improving enough to keep away from the medication. The task force from American Diabetes Association will focus on this group of patients to see if they can be considered cured.

The future is definitely not promising with one study had estimated that 1 of every 3 children born in the United States in the year of 2000 will eventually develop diabetes. On the other hand, a diabetes prevention study had revealed that daily exercise for 30 minutes and a 5 to 10 percent loss in body weight could actually reduce the risk of getting diabetes by nearly 60 percent and it is more effective than medicine in delaying its onset.

Though some health experts do admit diabetes could be prevented with diet and exercise, they also stressed that this is a one-way road and there is no turning back! Other doctors caution that for some diabetics, lowering of blood sugar may be temporary. If they later on experience stress, weight gain or any other factors, their blood sugar would surely be push back to the unhealthy level.
