Can eating American fast food often cause cancer?
I know hamburgers, French fries and fried chicken. Many people like to eat "foreign fast food", but "foreign fast food" has five hazards to health. Foreign fast food is an energy bomb. The biggest disadvantage of "foreign fast food" is that there is too much meat and too little food. There is a big meat pie in the hamburger, but there is only a lettuce leaf and a thin tomato. "Foreign fast food" drinks contain a lot of sugar, and "French fries" made of fried potatoes increase the calories of adults, which not only destroys vitamins, but also contains the toxic substance acrylamide. A "foreign fast food" can provide everyone with about one day's calories and fat. Nutrition requires that the ideal proportion of food calories should be: 60% from carbohydrates, 25% from fat, 12%- 15% from protein. In addition, it also requires low sodium (6-8 grams of salt per person per day), low sugar and high dietary fiber (20-30 grams per person per day). According to this standard, we can find that "foreign fast food" has three characteristics: high calorie, high fat and high protein; Three lows: low in minerals, vitamins and dietary fiber. If you eat fast food for three meals a day, it is roughly estimated that the total calorie intake can reach 3005 kilocalories, which is much higher than the daily calorie demand of middle-aged men of 2700 kilocalories and middle-aged women of 2000 kilocalories. There is a term in nutrition called "fat-heat ratio", and the normal standard is 20%-30%. Too high fat-heat ratio index and too low work are not good for health. The fat-calorie ratio index of "foreign fast food" is quite high, such as sandwich 52%, cream 90% and ice cream 52.9%. The calories provided by fat in "foreign fast food" reach 1440 calories, accounting for 48% of the total calories, which greatly exceeds the standard of 30%. In addition, the salt content in "foreign fast food" is high, and high sodium will induce hypertension. It is precisely because of the serious imbalance of fast food nutrition that international nutritionists call "foreign fast food" junk food and "energy bomb", and regular intake of these foods will induce obesity. "Foreign fast food" is addictive. American research shows that "foreign fast food" such as hamburgers, French fries and potato chips will cause changes in the endocrine system of the eater, making it difficult for people to control their food intake. People who eat "foreign fast food" for a long time, with the increase of weight, the body's resistance to leptin, a hormone, increases. It is leptin that can send signals to the brain to coordinate people's eating behavior. After eating "foreign fast food", the resistance to leptin makes it difficult for people to control their diet. The results of this study show that the obesity caused by eating "foreign fast food" cannot be simply attributed to the fact that obese people have no self-control, but that "foreign fast food" has a certain degree of addiction. The Swedish Food Safety Authority found that the brown skin on hamburgers, French fries, potato chips, roast pork and fruit desserts, as well as fried and fried foods contain a lot of acrylamide. Acrylamide can cause gene mutation, damage the central and peripheral nervous system, and induce benign or malignant tumors. Food cooked by western cooking methods such as frying, roasting and frying will produce acrylamide, a carcinogen. According to statistics, 30%-40% of food-related cancers are related to acrylamide. Experts believe that this discovery explains the high incidence of tumors in western countries. The International Center for Research on Cancer has listed acrylamide as a possible carcinogen for human beings. The World Health Organization stipulates that acrylamide should not exceed 1 mg per kilogram of food. According to the determination, acrylamide in American fast food chips is about 100 times higher than the specified standard. A packet of ordinary potato chips is 500 times over the standard. Recently, the US Food and Drug Administration also detected acrylamide in peanut butter, baby teething cake with black olive and plum juice and chocolate biscuits. Acrylamide was also found in fried chicken pieces. There are dangerous hydrogenated fats in "foreign fast food". Shortened oil and margarine used in making "foreign fast food" are hydrogenated fats made from natural vegetable oil, with a content of about 38%. 199 1 year, Professor Weidert, a nutritionist at Harvard University, pointed out that long-term consumption of trans fatty acids will affect the endocrine system of human body and have potential harm to health. "Foreign fast food" is mostly fried and baked food, and hydrogenated fat is widely used. Epidemiological studies show that the intake of chlorinated fat is directly related to the onset of heart disease and diabetes, and the intake of chlorinated fat also affects the content of cholesterol in blood. Professor Wecht of Harvard University concluded that "hydrogenated fat is worse than saturated fat" and "foreign fast food" can induce precocious puberty in children. American fried chicken is easy to cause precocious puberty and obesity in children, and the increase of obese children in China is related to this. It is reported that the endocrinology department of Tianjin Children's Hospital has treated some parents who took their children to treat precocious puberty. Some children's voices, breast development and physiological menstruation have changed when they were five or six years old. Once a mother came to see a doctor with her son who was less than six years old. The doctor found that the child has a secondary sexual characteristic, which is a manifestation of precocious puberty. The mother felt very wronged, saying that she never made up for her children blindly at ordinary times, and even took medicine very carefully. Asked about the child's diet, the mother said that the child likes fried chicken very much and eats it almost every day. The doctor's diagnosis is that the child has a serious partial eclipse, unbalanced nutrition and a large intake of high-calorie junk food, leading to precocious puberty. American parents call for "driving fast food out of campus". Some European cities are not allowed to build fast food restaurants in the city center, but the poor are prone to obesity. People at the bottom of American society are the most prone to obesity because they eat a lot of "junk food"-double sandwiches, chicken burgers, extra-large pizzas, large packages of fried potato chips and so on. American congressmen, consumer associations and parents believe that "obesity, like smoking, has become a public health problem" and call for "driving fast food out of campus". Some European cities also have regulations prohibiting the construction of fast food restaurants in busy city centers to reduce the temptation and harm of fast food to residents. The British medical community believes that the main reason for obesity and overweight in Britain is that there are too many "junk foods" in the market, and it is suggested that a "obesity tax" be imposed on hamburgers, carbonated drinks and cream cakes. Some members of the Chinese People's Political Consultative Conference (CPPCC) also called for limiting the development of "foreign fast food", and should also widely publicize that "fried, fried, baked and barbecued fast food is harmful to health". It is suggested that fast food enterprises be required to post a warning that "this kind of food is unhealthy" in a conspicuous position to remind consumers. Chinese cooking at low temperature is safer. The staple foods in China, such as steamed bread, rice and noodles, are cooked at about 100 degrees, far below the baking temperature. Chinese food is fried for a short time, and the instantaneous high temperature makes the temperature inside the food lower. This combination of high temperature and low temperature cooking method not only ensures the loss of food nutrients, but also meets the needs of food surface sterilization. At the same time, low-temperature cooking reduces the oxidation of oil, eliminates the generation of acrylamide, and makes dishes delicious and refreshing. Therefore, we should keep the traditional domestic eating habits and eat less "foreign fast food".
