Recently, many investigations have shown, the incidence of colorectal cancer is associated with the change of people's life style quietly increased. In a lot of influence factors, diet plays an important role. There is evidence that, in cancer patients, about 40% of the patients due to improper diet causes, including colorectal cancer.
Improper diet is a prominent characteristic of the heat, animal fat and cholesterol, excessive intake of dietary fiber and vitamins, such as the apparent lack of, as well as in the high calorie intake and accompanying movement too less. While maintaining an ideal body weight in the prevention of colorectal cancer: the first step.
Animal fat: cause of colorectal cancer.
Whether the international research or our data showed high animal fat diet resulted in high risk factors of colorectal cancer. The causes may include:
1, many carcinogens are fat-soluble, then dissolves in fat. Therefore, from the dietary intake of animal fat and more dissolution and absorption of carcinogens, the greater the risk of;
In 2, a diet high in fat may increase the intestinal bile acid secretion, the latter on intestinal mucosa has potential stimulation and damage. If the term in this stimulation and damage, may induce tumor cell generation, resulting in colorectal cancer.
Dietary recommendations:
1, eat or not to eat a diet rich in saturated fat and cholesterol, including: butter, lard, chicken oil, fat, fat, animal offal, fish, squid, cuttlefish, egg yolk, and palm oil and coconut oil;

3, do not eat or eat less fried, fried food;
In 4, moderate consumption of monounsaturated fatty acids in foods, such as olive oil, such as tuna;
In 5, during the cooking process, avoid the animal food and vegetable oil ( including excessive heating cooking temperature and heating time is too long).
Dietary fiber: the prevention of colorectal cancer by force
The dietary fiber is a plant that is not of human intestinal digestive enzyme hydrolysis and direct access to the components of e.. Numerous evidence, increasing dietary fiber intake can significantly reduce the incidence of colorectal cancer. The reason might be that dietary fiber has strong water absorption, can increase fecal volume, so that the debris forming, conducive to defecation. This can not only shorten the stool in the gut retention time, reduce carcinogen and intestinal wall contact, reduces intestinal carcinogens in concentration, thus reduce the occurrence of the risk of colorectal cancer. In addition, studies have shown that increased, soluble dietary fiber intake may also reduce
animal fats and cholesterol absorption, this also to a certain extent reduces the morbidity of carcinoma of large intestine opportunity.
Dietary recommendations:
In 1, the daily added dietary fiber30 g;
2, eat more fiber-rich foods: konjac, soybean and its products, fresh vegetables and fruits, such as algae;
3, in the maintenance of the staple of the same premise, using part of whole grains instead of flour and rice;
Vitamins and trace elements: action cannot small inspectVitamins and trace elements is to maintain the body's normal life activities of essential nutrients.
Although, with fat, protein and carbohydrate compared, they need a smaller quantity, itself does not produce heat, but they are in the prevention and cure of the role but can not be belittled. Many scientific studies show that, vitamin A, carotene, vitamin C, vitamin E, selenium and other trace elements in the prevention of malignant tumors have a potential role in.
Dietary recommendations:
1, pay attention to the supplement of fresh fruits and vegetables, especially carrots, peppers, tomatoes, rape, balsam pear, orange, orange, watermelon, strawberry and so on, to supplement the carotene and vitamin c;
In 2, moderate consumption of walnuts, peanuts, dairy products, meat, seafood, vitamin E supplementation;
3, pay attention to the uptake of malt, fish, mushrooms are rich in trace elements of selenium in food;
4, if due to various reasons, it is difficult to guarantee the food intake, but right amount vitamin and mineral supplement mixture;In addition to the above four points, in the diet should also pay attention to:In 1, the diversification of food, a single food model can not meet the needs of a variety of human nutrition;2, pay attention to natural and fresh food, do not eat moldy, smoked, baking, curing, hot food;3, such as drinking, drinking alcohol in moderation, not;
4, do not drink coffee and tea;
5, proper use is now considered a potential anti-cancer food, include: mushrooms, onions, garlic, asparagus, kiwi fruit. latin dance shoes
