Eating "coarse": the lack of dietary fiber in food is one of the important reasons for the increase of cancer patients in recent years. The finer the processing, the more dietary fiber is lost. Foods rich in dietary fiber are: black rice, corn flour, naked oats flour, fresh corn, millet and other staple foods; Mushrooms, Flammulina velutipes, edamame, broad beans, water bamboo and other vegetables; Pomegranate, mulberry, pear, kiwi fruit, fresh jujube and other fruits; Black sesame, pine nuts, dried almonds, dried walnuts and other nuts.

Second, eat "light": eat less high-fat, animal protein foods, natural light fruits and vegetables are appropriate, and properly control salt intake. For meat lovers, the intake of red meat should be below 500 grams per week, and processed meat products should be eaten as little as possible; It is best to limit the intake of white meat to 50 ~ 100g per day and only eat it 2~4 times a week. Salt and salty food may increase the incidence of gastric cancer, and it is best not to exceed 5 grams of salt per person per day. Be especially careful of the "invisible salt" around you. For example, potato chips and instant noodles in supermarket food, braised dishes, stews and old duck soup that northerners like to eat in restaurants.

Eat "miscellaneous": to prevent tumors, you don't need any panacea or precious medicinal materials. The key is to have a balanced diet, not picky eaters, mix meat and vegetables, and avoid eating cold and hot. As long as it is properly matched, colored foods such as red, yellow, white, green and black are all "anticancer drugs". The American Association for Cancer Research makes it clear that it does not recommend any specific anti-cancer food, but suggests that more than two-thirds of the food in the diet comes from vegetables, fruits, whole grains and beans.

Eat less: Researchers have found that people who "eat enough at every meal" are more likely to develop cancer than those who "basically eat only eight meals". At the same time of overeating, if you drink and smoke, it will make your health worse. Esophageal cancer, gastric cancer, pancreatic cancer and other digestive system tumors are all related to this. If you want to eat "eight points full", try the following tricks:

Start eating when you feel a little hungry, and eat every meal at a fixed time to avoid eating too much and too fast after being too hungry;

Make sure to eat for at least 20 minutes, because it will take 20 minutes for the brain to receive the signal of satiety;

Use a small spoon instead of chopsticks, chew more than 30 times per meal to slow down;

Eat more crude fiber foods that increase satiety, such as beans and konjac;

Serve a little less at a time, or use shallow dishes and transparent tableware.

Eat "rotten": except fresh fruits and vegetables, all other foods should be cooked thoroughly. An Italian study found that carotene, lycopene and lutein are not afraid of cooking at all, but they can protect the body from cancer cells more than raw food. Especially carrots and tomatoes, broccoli and cruciferous vegetables rich in carotenoids. Taking broccoli as an example, it is ideal to heat it to 60℃, which can maximize its anticancer activity and reduce the risk of esophageal cancer, gastric cancer, lung cancer, gallbladder cancer and skin cancer.
