Colon cancer incidence and mortality in our country, although lower than gastric cancer, esophageal cancer, lung cancer and other malignancies, but in recent years, with the improvement of living standards, changes in diet, and its incidence is rising year by year. Such as Guangzhou, the incidence of colon cancer in men of various types of cancer ranks fifth in incidence in female cancer ranked fourth. The incidence is growing at over 2% per year rate of increase. Experts believe that the incidence of colon cancer with a poor diet have a great relationship. If large intake of high animal protein, high-fat, plant cellulose is a serious lack important cause of rising cancer, colon cancer prevention should start with Science Diet.
Eat foods rich in vitamin D and calcium foods
The researchers found that a daily diet drop into more than 150 international units of vitamin D in colorectal cancer incidence by only a small amount of vitamin D intake by half, while the daily intake of about 1,200 milligrams of calcium for more than just the incidence of colorectal cancer equivalent to 625 mg of calcium intake less than one quarter of a day. So scientists have concluded that calcium intake and the risk of colorectal cancer was negatively correlated with vitamin D has the potential anticancer effects. Since calcium with high affinity for lipids, can be combined with long-chain fatty acids in the intestinal tract and secondary bile acids, lipids reduce damage to cells and prevent mutation of intestinal epithelial cells. Therefore, the role of antagonist with trigger fat diet on colon cancer. Vitamin D-rich foods such as cod liver oil, liver, egg yolk. Calcium-rich foods such as dairy products, shrimp, beans, green vegetables, sesame, seaweed, seaweed and so on.
Eat more foods rich in folic acid
H-r acid is a B vitamin. The study found that increased dietary folate intake, increased serum levels of folic acid can significantly reduce the incidence of colon cancer. The researchers also found that, with respect to the election ends of the colon and rectum cancer, increased intake of folic acid to reduce the incidence of colon tumors proximal to more significant role. Experts recommend adult daily folic acid supplement of 400 micrograms or more. Folate-rich foods are animal liver, eggs, beans, yeast, green leafy vegetables, fruits, nuts and so on.
Eat foods rich in selenium
Selenium is a trace element has anticancer effects of foods high selenium content and high blood selenium levels in areas of breast cancer, colon cancer, prostate cancer and leukemia prevalence is very low. Some scholars in the control study found that selenium and placebo, 200 micrograms a day of selenium supplements can make to reduce the incidence of colon cancer by 58%. In addition, higher blood selenium concentrations are rarely found more than one centimeter in diameter tumor. Selenium is glutathione peroxidase active ingredient. The enzyme with anti-peroxidation function to prevent lipid peroxidation, thereby protecting the cell membrane damage from harmful reactive oxygen free radicals, maintain the integrity of cell structure and function. Selenium-rich foods include seafood, animal liver, meat, and grains grown in selenium-rich soil, nuts and so on.
Eat foods rich in fiber
After analysis by experts found that diet, intake and the incidence of colon cancer was negatively correlated with dietary fiber, intake of more than 35 grams of fiber each day, can reduce the incidence of colon cancer of 40%. Further study found that a lack of food, fiber can reduce the amount of stool, bowel movement slows down, so the concentration of carcinogenic substances in the intestine increased carcinogenic effects of intestinal mucosal wall of prolonged prone to colon cancer. Fiber-rich foods such as whole grains cable, beans, vegetables, and fruits.
Eat high-fat foods
The study found a high incidence of colon cancer in high-fat diet for its characteristics, and low prevalence countries were lower fat content of the diet. High-fat diet can cause stool acid metabolites (deoxyribonucleic acid, lithocholic acid), cholesterol metabolism (steroids and steroid ketone) and p-glucuronidase activity increased bacteria or carcinogens such or tumor promoters, may lead to colon cancer. So eating too much fat, directly or indirectly related to colorectal cancer. Chinese residents in recent years to improve living standards, the large increase in fat intake, Beijing, for example, per capita daily intake of more than 50 grams of cooking oil, and the Chinese Nutrition Society recommended intake is 25 to 30 grams and therefore To prevent intestinal cancer, we must first control the fat, eat high-fat foods.
Eat broccoli also can prevent colon cancer
Cruciferous family of vegetables are rich in vitamins, such as broccoli contains vitamin C than oranges contain vitamin C, minerals and dietary fiber content a lot. Additionally, cruciferous vegetables in a variety of potent antioxidants that can help us eliminate pollution, to accelerate its detoxification process.
They also contain natural chemicals called glucosinolates are, and to get rid of toxins, including carcinogens. One study showed that three times a week to eat cruciferous vegetables can reduce the risk of colon cancer by 60%. Therefore, to enhance resistance to disease, improve the body's ability to detoxify, eat at least three times a week, "Ten cauliflower."
Some people believe that cruciferous vegetables rich in plant fiber is difficult to digest, so it is "off the table outside", in fact, once you have a good cooking methods, as these vegetables are easily digested stomach.
The best way is to tender fried processing, such as short steaming, stir quickly fried or steamed to retain nutrients in vegetables, fiber also helps to break down, making it easier to digest. When steaming fried, add a small amount of oil in the pan, stir fry vegetables for a minute, then add a little water, or water, soy sauce and lemon juice mixed spices, cover, about 3 minutes to steam.
Calcium foods can prevent colon cancer
Calcium not only improve osteoporosis, but also to prevent colorectal cancer. This conclusion is not groundless, Memorial Sloan - Kettering Cancer Center researchers have had colon cancer, colorectal cancer risk population survey found that awareness of dietary calcium by 2 to 3 months, the rate of cell division slows down the gut, reducing intestinal cancer.
In this regard, experts pointed out that a combination of calcium can be absorbed and fatty acids in the intestine, bile acids and other carcinogens; calcium also affects cell biochemical reactions, the regulation of cell growth, and thus play a role in the prevention of intestinal tumors. Moreover, research has shown that daily intake of more than 412 mg of calcium from the diet, intake of at least 800 milligrams of calcium from calcium products in women suffering from colon cancer risk reduction of 46%. Therefore, we can say that the amount of calcium, to some extent, be able to withstand colorectal cancer.
