1, eat less sugar

The favorite "food" of cancer cells is sugar. Japan's book "How to Prevent Cancer" points out that when blood flows through a tumor, about 57\% of blood sugar will be consumed by cancer cells and become a nutrient to nourish it. According to the American Journal of Clinical Nutrition, as long as you drink two sweet drinks every day, the risk of pancreatic cancer will be 90\% higher than that of people who don't drink. Hao, director of the Department of Pancreatic Oncology of the Cancer Hospital affiliated to Tianjin Medical University and a member of the American Cancer Fund Research Association, said that it is best to eat less or no sugary food. It is generally believed that the sugar intake per person per day should be less than 50 grams.

Open the window for at least half an hour.

Few people know that in addition to formaldehyde, there is also a strong carcinogenic gas-radon and its daughters. It is usually hidden in granite, cement and ceramic tiles. It spreads indoors along the gaps in these places and enters the human body through the respiratory tract. After a long time, it will induce lung cancer. In fact, as long as the window is opened for half an hour every day, the concentration of radon can be reduced to the same as that outside. In addition, natural gas will also produce radon after burning, so when boiling water in the kitchen, it is best to open the window and close the door connected to the living room.

3. Eat with onions and garlic.

In China, the province with the lowest incidence of gastric cancer is Shandong, a big onion and garlic planting province. Cangshan County, Shandong Province is the first of the four counties with the lowest mortality rate of gastric cancer in the north of the Yangtze River, with an average of 6 kilograms of garlic per person per year. Experts pointed out that this is related to the antioxidant effect of allicin and its ability to reduce the content of carcinogen nitrite in human body. Studies have shown that people who eat more garlic will reduce the risk of gastric cancer by 60\%. Garlic can only be produced when it is crushed and fully combined with oxygen, and it is very unstable and will soon lose its effect once heated. So it's best to crush garlic and eat it raw, or chop it into garlic paste and put it in the cold salad.

Second, the key points of health care

1, nourish yin and pay attention to drink plenty of water.

In dry autumn and winter, the water evaporated through the skin every day is more than 600 ml, so it is very important to replenish water. An adult should drink at least 1500ml of water every day, and 2000ml in autumn can ensure the lubrication of lungs and respiratory tract.

Although it is recommended to drink more water every day for health, weight loss and beauty. Drinking a lot of water at a time without thirst will be counterproductive. When water exceeds the amount necessary for the body, the water content in cells will rise and swell. The worst result will be "water poisoning" and life-threatening. The correct amount of drinking water should be adjusted according to one's daily activities. Under normal circumstances, drink at least 1.5~2L of water every day. Control the water consumption at 1~2 cups each time.

2. Wear clothes to keep warm.

Some people are careless and didn't add clothes in time when it was cold; Some people wear less clothes and don't button their coats for beauty. Early in the morning and at night when the cold wind is strong, the abdomen is easy to catch cold. Especially for women with spleen and stomach deficiency and cold, once it is cold, they will have stomachache and diarrhea, which is a natural reaction of gastrointestinal tract. The best and most convenient way is to put on more clothes, especially to wrap your waist and abdomen tightly.

The first criterion for choosing winter clothes is to keep warm. Among many kinds of clothing materials, wool, chlorine fiber, acrylic fiber, silk and acetate fiber viscose cotton have the highest warmth retention, while nylon, polypropylene fiber and polyester are not suitable for keeping out the cold because of their high thermal conductivity. The more air the fabric contains, the better its warmth retention. Thick wool fabrics and silk contain a lot of air, so they keep warm well. In particular, the pores of wool fabrics are not straight through, which has better warmth retention.
