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, and 3/4 of them occur in Southeast Asia (including China, North Korea and Japan). The occurrence of liver cancer is related to poor dietary habits, for which experts have proposed four principles of eating and not eating. 1.Carrot citrus The protective effect of vegetables and fruits on the liver is produced by the interaction between the vitamins, minerals, fibers and so on. 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 of about 400-800 grams a day can reduce your risk of liver cancer by 20 percent. 2.Drink Tieguanyin People in southern Fujian love to drink tea, Dr. Dong said, 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, etc., on a daily basis with controlled drinking, the chances 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, eat more “three shoots” three shoots, namely bamboo shoots, lettuce and asparagus. Experts suggest that eating more of these three kinds of food everyday can reduce the incidence of liver cancer, and they are also delicious. 1. Do not eat moldy food In spring, food is very easy to moldy. Aflatoxin in moldy food is a liver cancer causing substance, the shortest time required for cancer is only 24 weeks, so food should be properly stored, once moldy, should be immediately discarded, 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 appetizing, the next hot weather, appetite is not good, many people prefer to pickles next meal. But 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. And remember, must be pickled through before eating. Once the cells of stomach are injured, the toxic substances in food will be easily absorbed by stomach, which will easily cause alcoholic hepatitis, damage the detoxification function of liver and even cause alcoholic cirrhosis, which is a risk factor of liver cancer. If moldy peanuts are used to drink, the possibility of inducing liver cancer will be even greater. Dr. Dong suggested that adult men should not drink more than the amount of alcohol per person per day.
