”Vegetables and fruits contain various vitamins and other nutrients that play a great role in fighting cancer, but they cannot provide us with protein.” “Therefore, we should eat less high-fat and high-protein foods and more fruits and vegetables to establish a good dietary structure, and strive to minimize the damage to the human body with a balanced intake of various nutrients.” The U.S. Department of Agriculture has created a “pyramid” food structure for the treatment of colorectal cancer. The bottom of this “pyramid” consists of various grains, pasta and rice, the middle of the tower is vegetables and fruits, the top of the tower is meat, poultry, aquatic products, eggs, beans and dairy products, and the tip of the tower is high-fat food. In fact, this is exactly the traditional recipe in China, and is also a more scientific diet with structure. Due to the different genetic factors of individuals, different people have different chances of getting cancer under the same external environment. For those who have a family history of cancer, a scientific and reasonable diet with structure becomes more important. There is a lesson in “chewing and swallowing slowly” When eating, we should pay attention to “chewing and swallowing slowly”. “Chewing slowly” can not only help us taste the delicious food, but also effectively prevent and treat cancer. Xiao Wenhua told reporters that people can produce salivary enzymes such as oxidase and peroxidase in the process of chewing, and these salivary enzymes can kill carcinogens when they enter the body. Some medical doctors believe that the higher incidence of cancer among middle-aged and elderly people is related to their poor chewing ability, and believe that cultivating good eating habits, chewing slowly, and chewing each mouthful of rice 30 times can help eliminate carcinogens in food. In addition, “chew slowly” can also effectively prevent overheated food from entering the esophagus. “The nerve cells of the esophagus are less sensitive to ‘heat’ compared to the nerve cells of the mouth, so when we swallow overheated food, we don’t feel hot, but in fact it’s still very hot. Thus our esophagus and stomach mucosa will be scalded and inflamed, and then there is a risk of cancer.”
