Eating more coarse food can prevent cancer

Experts pointed out that coarse food has not only become an essential nutrient for the body, but also can prevent a variety of cancers Coarse grains include corn, cereal and other complex carbohydrates rich in cellulose The cellulose content in these foods is very high, which can stimulate the gastrointestinal tract and promote defecation after entering the body, so as to reduce the absorption of carcinogens by the intestinal tract and prevent the occurrence of colorectal cancer The coarse grain is also rich in trace elements such as calcium, magnesium, selenium and a variety of vitamins, which can promote metabolism, enhance physique and delay aging Selenium is also an anticancer substance, which can be mixed with various carcinogens in the body and discharged from the body through the digestive tract In recent years, the lack of plant fiber in food is one of the important reasons for diabetes, cardiovascular and cerebrovascular diseases, cancer, and dietary fiber can prevent colon cancer, rectal cancer, intestinal diverticulosis and so on The anti-cancer principle of plant fiber lies in its role of "cleaning the intestinal tract" It can promote intestinal peristalsis, shorten the passage time of intestinal contents, and reduce the possibility of carcinogens being absorbed by human body In addition, protein, fat, sugar and other three nutrients excess is also a cancer promoting factor, resulting in obesity is often some of the causes of endocrine related cancer Research shows that high fiber diet in coarse grains can block the absorption of these three nutrients, reduce obesity and effectively prevent cancer All kinds of grain are originally the source of dietary fiber, but affected by the processing, especially the more refined the grain processing, the more loss of plant fiber, so we should eat some brown rice, coarse flour and other grains At the same time, experts remind that it is better to eat fresh coarse grains On the one hand, the nutrient content of fresh coarse grains is rich, on the other hand, fresh coarse grains are not easy to be polluted by aflatoxin.
