There is no doubt that Morgan Spurlock's test is too extreme, as very few people consider fast food as their only food. Therefore, some people also point out accordingly that as long as it is not consumed all the time or every day, it will not do much harm to the human body.
"This view is incorrect!" Li Qingtian, director of the Chinese Nutrition Society, pointed out in an interview with the reporter that foreign fast food belongs to the typical "three high" (high calorie, high fat, high protein) food, such a dietary structure in nutrition is absolutely unreasonable. "Foreign fast food food types are no more than so few, we can analyze one by one." Li Qingtian will be foreign fast food according to the type of food to be categorized as a detailed explanation.
"The first big killer is fried food. French fries and other fried food is the culprit of cardiovascular disease. Especially french fries are high-fat food, potato original fat content of less than 1%, but because of the potato expansion of large, deep-fried up to about 40% of the fat content. Fried food high temperature, will produce benzopyrene and other carcinogens. Deep-frying also destroys food vitamins and denatures proteins. Barbecued chicken wings and other barbecued foods contain a large amount of 'triple quadruple benzo(a)pyrene' (the first of the three major carcinogens), which will lead to protein charring and denaturation (aggravating the burden on the kidneys and liver). One study says that 1 fried chicken leg is equal to the toxicity of 60 cigarettes."
"The white flour in the burger base is a refined food, and the focal physiological effect on the body is the production of calories. Human nutrition history shows that long-term too refined food people, easy to cause coronary heart disease, diabetes, arteriosclerosis and myocardial infarction. Since the burger contains a lot of cream and only one or two pathetically small slices of lettuce or pickle are sandwiched in, it is very high in fat and extremely low in vitamins."
"The problem of salt is also not something we can ignore." Li Qingtian pointed out that McDonald's has also been "blacklisted" by Britain's Times newspaper because of its excessive salt content. The World Health Organization suggests that the daily salt intake per person should not exceed 5 grams, and our nutrition experts suggest that it should not exceed 10 grams. "If you eat too salty for a long time, it will not only induce cardiovascular and cerebrovascular diseases, but also cause gastritis, peptic ulcer and other diseases."
"Carbonated drinks in foreign fast food can be considered an accomplice." Li Qingtian added. Cola and other carbonated drinks contain phosphoric acid, carbonic acid, will take away the body's calcium, and contains too much sugar, there is gas, there is not much nutritional value, drinking a sense of fullness, affecting the main meal. Many children refuse to eat properly for this reason. Cone and other frozen dessert food containing sugar, cream, very easy to cause obesity, high sugar content will also affect the main meal.
Professor Zhao Lin, a nutrition expert at the General Hospital of the Chinese People's Liberation Army, also pointed out that hamburgers and French fries can cause hormonal changes in the body, which can make the eater addicted, making it difficult to control the amount of food eaten. The study also found that hamburgers, French fries, fried potato chips, pancakes, roast pork, fruit desserts on the brown crunch, cookies, cakes and other foods contain large amounts of acrylamide. Acrylamide is known to be a natural by-product of high-temperature frying, baking or roasting of carbohydrate-rich foods. Acrylamide can cause genetic mutations that can damage the central and peripheral nervous system and induce benign or malignant tumors. Experts believe that this finding explains the high incidence of tumors in Western countries. The World Health Organization (WHO) stipulates that acrylamide should not exceed 1 mg per kilogram of food. But acrylamide levels in French fries currently sold by McDonald's and KFC are about 100 times higher than that standard, and an ordinary bag of fried potato chips exceeds the limit by about 500 times, as do acrylamide levels in bread, cakes and cookies.
Zhao Lin also pointed out that the hydrogenated fat (shortening, margarine) commonly used in foreign fast food is even more harmful than saturated fat. He told reporters that the Harvard University School of Public **** Health Department of Nutrition director Walter Willett published a paper as early as 1991, clearly pointing out that foreign fast food and other use of hydrogenated fats on human health potential hazards. Hydrogenated fats are commonly found in both fried and baked foods in fast food. Willett said, "Controlled diet studies of the effects of fats on blood cholesterol and epidemiologic studies of the relationship between intake of hydrogenated fats and the chances of developing heart disease and diabetes have shown that hydrogenated fats are worse than saturated fats."
