Liver cancer is one of the most dangerous cancers to human health, and most patients with liver cancer will die within one year of contracting the disease. According to the World Health Organization, there are 430,000 new cases of liver cancer each year, with 3/4 of them occurring in Southeast Asia (including China, North Korea and Japan). The occurrence of liver cancer is related to poor dietary habits. 1.Eating carrot citrus The protective effect of vegetables and fruits on liver is produced by the interaction between vitamins, minerals, fibers, etc. in them. Green leafy vegetables, carrots, potatoes and citrus fruits have the strongest preventive effect. Dr. Jing Dong suggests that you should eat five or more kinds of vegetables and fruits every day, including a glass of juice in the morning, a piece of fruit in the morning and afternoon, and two or more servings of vegetables at the main meal, so that the total intake is about 400-800 grams a day, which can reduce your risk of liver cancer by 20%. 2.Drink tea Southern Fujian people love to drink tea, which is good for preventing liver cancer, especially Tieguanyin, which is common in Southern Fujian, and Longjing before rain is also good. 3.Eating dairy products Medical research proves that if one consumes dairy products, including milk and yogurt, under the condition of controlled drinking, the chance of developing liver cancer will be reduced by 78%. At present, children have developed the habit of consuming dairy products, but not many adults consume dairy products, it may be improved. 4, three bamboo shoots, namely bamboo shoots, lettuce and asparagus. Experts suggest that eating more of these three foods on a daily basis can reduce the incidence of liver cancer, and they are also delicious. ”4 do not eat”: 1, do not eat moldy food in spring, food is very easy to mold. Therefore, food should be properly stored and discarded once moldy, especially soybeans, peanuts, sweet potatoes, sugar cane, etc., should not be consumed again. In addition, peanut oil should also not be stored for a long time, if found to produce harsh taste should not be eaten. Otherwise, not only the taste is bad, but more importantly, it will lead to cancer. 2, do not eat or eat less pickles pickles, pickles, salted fish and other pickles refreshing appetizing, the next hot weather, appetite is not good, many people prefer to pickles next meal. But the pickles contain a higher amount of nitrosamines, experimental evidence related to the occurrence of liver cancer, it is best not to eat or eat less.

If moldy peanuts are used for drinking, the possibility of inducing liver cancer will be even greater. 4, animal and vegetable oils should not be consumed after deterioration of stale oils contain malondialdehyde, a chemical component that can generate polymers and react with proteins and deoxyribonucleic acid in the body, causing the structure of proteins to mutate, resulting in the loss of normal function of the cells of mutated proteins and transformation to initial cancer cells. In addition, malondialdehyde polymers prevent the replication of DNA and accelerate the aging process in humans. Therefore, animal and vegetable oils should not be stored for too long, and oils that have deteriorated and produced a harsh taste should not be consumed. The food made by frying with harsh oil not only tastes bad, but more importantly, it can cause cancer and shorten the life span of people.
