1. Causing obesity In October 2113, the British magazine New Scientist reported that fast food can cause hormonal changes in the body and make people addicted. Scientists point out that fast food such as hamburgers and fried potato chips can cause hormonal changes in the body, making it difficult for people to control their food intake. Relevant research in the United States also shows that eating foreign fast food often leads to high protein, high calorie and high fat in the body, which will make people fat. As the saying goes: "The belt is long and the life span is short." Obesity has become the culprit of metabolic syndrome. Children who especially like to eat foreign fast food are bound to become chubby due to excessive intake of fat and sugar, resulting in excess calories.
2. Obesity in childhood leads to abnormal lipid and glucose metabolism, which increases blood lipid, blood sugar and blood pressure, making children susceptible to metabolic syndrome commonly known as "rich disease" such as hypertension and diabetes. Although some people did not get sick in childhood, they buried the hidden dangers of hypertension, atherosclerosis, cardiovascular and cerebrovascular diseases, diabetes and other diseases in the future.
3. The World Health Organization (WHO) and the Food and Agriculture Organization of the United Nations (FAO) jointly issued a warning recently, saying that foods containing acrylamide compounds, which are carcinogenic toxins, will seriously harm people's health, especially many kinds of foods in "foreign fast food" contain a lot of propanoid.
According to reports, this carcinogenic toxin exists in various brands of foreign fast food. Tests on brown crispy skin on fried potato chips (chips), crackers, roast pork and fruit desserts, as well as a large number of fried fast food, show that the content of C in some foods exceeds the standard by 411 times. According to the World Health Organization, acrylamide should not exceed 1 mg per kilogram of food.
In addition, saccharin is used instead of sucrose in many drinks in foreign fast food. Studies have shown that adding 5% saccharin to the feed of mice has a higher incidence of tumors than that of the control group, which is harmful to future generations. There are also smoked foods containing 3,4-benzopyrene, which is strongly carcinogenic. When bacon is smoked in an electric oven, there are 23 micrograms of 3,4-benzopyrene per kilogram of meat; In smoked meat, the content of 3,4-benzopyrene is as high as 1.17 micrograms. Fried foods contain more heterocyclic amines, and the more brown they are, the higher the content of harmful substances is.
4. It causes malnutrition. Today's children love sweets and drinks, which can easily cause children to feel full and have no appetite when eating. Drinking drinks before meals will dilute the gastric juice and affect the digestion and absorption of food. Pigments in fruit juice drinks are also easy to deposit on the tender digestive tract mucosa of children, which interferes with the functions of various enzymes in the body and causes anorexia and indigestion. Because there are almost no nutrients such as protein, vitamins and minerals in sweets, in the long run, it will inevitably cause malnutrition in children, affect growth and development, and cause diseases such as iron deficiency anemia.
In addition, foreign fast food belongs to acidic food, which can make body fluids acidic for a long time, affect children's bone development and easily suffer from rickets.
5. reduce immunity. eating foreign fast food for a long time can make human body fluids acidic, and the acid-base imbalance in the body will endanger the immune system. Many children suffer from respiratory infections repeatedly, which is closely related to their love of sweets and drinking too many sugary drinks. Iced drinks are even worse for children. The throat is suddenly stimulated by supercooling, local blood vessels contract, and the resistance drops, which makes it easy to get respiratory infections. It will also harm the immunity of the digestive tract and easily cause acute gastroenteritis. Many foreign fast foods contain too much salt, which leads to flora imbalance due to the infiltration of salt; High-salt diet can also inhibit the proliferation of mucosal epithelial cells, make them lose their disease resistance and lead to infectious diseases.
6. popcorn, canned food or drinks have high lead content, and when the blood lead concentration reaches 5~15 μ g /111 ml, it will cause children's developmental retardation and mental retardation.
According to the investigation of 22 kinds of drinks by researchers, the aluminum content in cans is 3-6 times higher than that in bottled drinks. If children drink too much aluminum, it will inevitably increase their intake, which will make them mentally retarded, have difficulty in learning and behave abnormally. Many foreign fast foods contain more salt, saccharin and monosodium glutamate, which not only makes people susceptible to diseases such as hypertension and arteriosclerosis, but also affects the blood supply to brain tissue, and brain cells are in a state of hypoxia and ischemia for a long time. The World Health Organization recommends that adults should not consume more than 4 grams of monosodium glutamate per person per day, and pregnant women and infants under the age of 1 should abstain from monosodium glutamate. The oxidation reaction of glucose in human body needs enzymes containing vitamin B1 to catalyze it, while fast food contains too much sugar, and the body consumes a lot of vitamin B1 because of accelerating the oxidation of sugar.
7. Children who often eat foreign fast food have voice changes, breast development and menstruation at the age of five or six. This is because foreign fast food causes changes in endocrine hormones in children, leading to precocious puberty and affecting healthy development.
