There are fat as a result of

In the South Pacific island nation of Tonga, Nauru and the Federated States of Micronesia on the island of Kosrae, cheap instant noodles and fried chicken have to replace the traditional fish and taro has become the common people of choice for the table. In Mexico, 105 million of 40% of the population living in poverty, but the 2 / 3 of the population belong to the obese population.

As a high-calorie "junk food" the birthplace of the United States is still the country to highlight the problem of obesity, 2 / 3 of Americans over weight. The development of science and technology to speed up the production, processing and marketing aspects of the operation, so that high-calorie food production plant to spread rapidly worldwide. Cheap delicious high-calorie food more readily available, the increase in the global obesity epidemic.

"International Working Group on Obesity" policy director Neville Rigby said: "In particular, developing countries have to bear the burden of obesity trends. We are even seeing young people in India are obese. This is a universal problem. It has become completely The global epidemic. Is in fact infectious diseases. "

Reduce the amount of exercise also contributed to the increasing problem of obesity one of the important factors. People spend more time inside the car, in front of the TV and computer.

"The telephone, automobile, computer-dependent people from out of fear of hunger after the freedom," Imperial College London, Professor Stephen Bloom said, "but this had a negative impact."

The human appetite for the 21st century "new enemy"

"I think people's attention has been eating and breathing in the range between," Bloom said. However, without the restraint of appetite caused by the consequences of more of a concern.

According to statistics, the world's nearly 1 / 3 of deaths and cases of obesity, lack of exercise and smoking-related. Individual cases, the number of obese people who are born premature death Bi Changren 5 to 8 years.

Each year, the world's 300 million people die of obesity-related type 2 diabetes. Such cases usually lead to heart disease and kidney failure, the current number of patients has reached 154 million, more than the number of HIV infections. According to the World Health Organization predicts the next 25 years, the figure could double.

Obesity may increase the risk of heart disease. WHO data show that the global total of 17,000,000 people die of heart disease and other diseases of the circulatory system, the total number of deaths 1 / 3. In most countries, died of a heart attack in the case reached the working age group of adults to be even more common.

The Earth Institute at Columbia University study found that Brazil, China, India, South Africa, 30 to 59-year-old crowd of heart disease death rate is twice as the United States, Russia is higher than 5 times.

"The United States" is a curse?

New Zealand's Otago University nutrition professor and an expert on global obesity Jimu Man said: "If there should be criticized in the United States, and that is to the world's output of food industry of the United States have too much capacity around the U.S. government decision-making. The United States has become a Kinds of very complex factors, the role of a disease. "

Some experts believe that although the United States to Coca-Cola, McDonald's and other "junk food" and beverages as well as their way of thinking to sell to the world, but it should not therefore to blame all the world's obesity trend "of the United States." Neville Rigby said: "We see the United States is not just a social phenomenon, but a group of cross-border phenomenon." Jimu Man also believes that the ability to resist the United States and the concept of eating food, after all, a matter of personal choice .

In the face of the spread of obesity trends, some countries have taken measures to resist. For example, Singapore has strengthened the school sports activities to bottled water instead of soft drinks. Brazilian government ordered an increase in school lunches in the proportion of fruits and vegetables. International Diabetes Institute Paul Zimmet said, to help people buy health food and exercise to strengthen, most of the limited government action. Professor Stephen Bloom said: "If we can control the current obesity trends, it would be the cause of public health is an important achievement."

Obesity and immunity

"Know thy enemy and know, Baizhanbudai" This is a very famous ancient military terms, were not sick, their own defense and the ability to identify very well the immune system is often said.

Immunity is the body's immune system to identify "their" and "non-self" components, and exclusion of the physiological functions of heterogeneous material. Abnormal body can produce its own role in the organization of the injury, which has three main functions, namely: the role of defense, that is, anti-infective immunity, had the role of strong performance for the allergy; machine to maintain a balance in the body, such as the removal of old or damaged cells damage, Over the role of strong performance for autoimmune; immune supervision, that is, the removal often occurs in the body of abnormal cell variants, when the weakened role, such as the elderly prone to cancer. Obese people on the face of it very sturdy, and it is a matter of fact, "there are only empty table." Immune function in obese people do?

You will see in the daily lives of obese people susceptible to cold, but not easy to quickly turn for the better; obese people with asthma after exercise will Shishi; subcutaneous fat people often play "pimple." All of this shows that obese people's defense system problems, low immune function.

Obese people can change the lower immune function, depends entirely on how to lose weight. Resistance is the human immunodeficiency virus, bacteria and toxins into the body of a defense, foreign bodies swallowed by the macrophages, to attack foreign bodies and the formation of antibodies and T cells, B cells shared. Ichiro Kono was obese boys on the team before the weight loss and weight standards of comparison, the phagocytes engulfed foreign body's ability to lower than normal 20%, T cell capacity was 30% lower, but the weight loss, the macrophage is the ability to swallow and standards The same group, T cell function also returned to normal.

Obesity increase the human immunodeficiency help to avoid infection, and enhance physical, the best way to lose weight or cure disease.
