A large number of studies show that the long-term harm of cancer in developed countries lies in the diet with high calorie, high fat and high protein.
High calorie. The whole raw material composition of "foreign fast food" is characterized by high calorie. For example, the base material of bread is high-precision white flour, because of the high processing precision, most of the nutritional and health-care ingredients beneficial to human body are lost in raw wheat grains. According to the scientific theory that the nutritional value of flour is inversely proportional to the processing accuracy, the key physiological function of white flour in the base material of "foreign fast food" lies in the problem of "heat". The history of human nutrition shows that people who overeat for a long time are prone to coronary heart disease, diabetes, arteriosclerosis and myocardial infarction.
High fat. The frying process in "foreign fast food" moistens a lot of fat into food, which makes the fat content of food suddenly increase. The original fat content of potato was less than 1%, but the fat content after frying can reach about 40% due to the large expansion of potato. However, some animal fats in "foreign fast food" are mainly saturated fatty acids and contain more cholesterol, which is easy to deposit on the blood vessel wall, leading to arteriosclerosis and hypertension.
High protein. The prominent feature of "foreign fast food" is eating animal meat such as beef. Meat is characterized by high protein, high calorie and high fat. Excessive consumption has great side effects on human body, especially beef. Among the "three high" foods, beef consumption is a pollution source with great carcinogenic effect.
In recent years, the United States has vigorously promoted healthy foods: whole wheat flour, whole grains and soybeans, and introduced relevant management measures. However, the "three highs" fast food is still "repeatedly banned", mainly because the typical mode of "three highs" diet is in tune with the modern fast-paced life and can meet the consumption psychology of modern people.
The processing technology of "foreign fast food" is the fatal pollution source of American poisoning.
Known by American society as "the combination of Bernstein and Woodward", Nichols Fox's research results on food and toadstools once shocked the whole country. It makes the giant poison "E.coli O 157∶H7" a household name, and makes Americans more and more realize from "foreign fast food" that the garbage nature of "foreign fast food" such as hamburgers not only has the serious pollution consequences of obesity, hypertension, heart disease, diabetes and a series of cancers under the "three highs" food structure, but also the pollution of its production and processing technology. The pollution source is the processing technology of hamburger patties.
Nichols Fox's achievement reveals in great detail the disadvantages in the process of making "foreign fast food" patties: in order to ensure that the patties served are as fresh as possible, fast food restaurants generally stipulate that patties must be frozen in a low-temperature cabinet near the grill; When the hard frozen meat pie is sent to the hot metal grill, you can still hear the clang of ice colliding with metal ... because the chef has been using a certain part of the grill, where the temperature will drop due to constant contact with frozen meat. This means that the meat pie is not completely baked and the inside of the meat pie is not cooked. Under this process, it is difficult to completely eliminate the pollutants in the meat pie. For example, Escherichia coli O 157∶H7 was detected in meat samples from Ohio, and samples collected from Michigan and Oregon were of the same serotype as hamburger patties. Studies have shown that cattle are the hosts of Escherichia coli O 157∶H7, and beef or milk produced by cattle carrying this bacterium contains this bacterium, and its pollution is caused by cow dung. Especially before slaughter, cows are routinely kept in crowded cowsheds, with feces all over the floor, and then hungry for a day or so, hollowing out their intestines. This process is more conducive to the spread of pathogens. Development is to send a lot of beef from different sources into the meat grinder together, and then the germs in the infected meat will affect all the minced meat. In fact, beef and milk may be contaminated by this bacteria before and after slaughter and during milk production in slaughterhouses.
In the food safety investigation, it was found that the "Doll Box" fast food chain store, which caused serious poisoning, was seriously polluted by bacteria because of its inferior technology and its internal humidity just reached 1 10 Fahrenheit (350 Fahrenheit is about 177 Fahrenheit). As a result, more than a dozen States, such as Minnesota and Huasheng, have caused serious poisoning to American consumers. Fox survey results show that more than 200 large-scale poisoning incidents occurred in a short period of time. Family collective poisoning, adolescent collective poisoning, North Carolina day care center collective poisoning.
