As early as 1930, researchers discovered that low-fat diet can prevent breast cancer.
At that time in Asian countries, fat provides only the total daily calorie intake of less than 20%, while the Western countries, fat intake of up to 40% of total daily calories, accordingly, the Asian countries the incidence of breast cancer are generally higher than Western countries are several times lower. And when low-prevalence countries in the region’s population immigrated to Western countries, along with the changes in eating habits, the incidence rate will gradually become and Western countries. Animal experiments have proved that when exposed to the same cancer-causing factors, high fat diet low-fat diet in mice of small rodent breast cancer were more.
Studies have shown that fat intake and the level of estrogen. From the high fat diet to a low-fat diet, the cytoplasm within a few weeks of estrogen receptor level will drop. There are a number of studies have shown that low-fat diet and avoiding obesity, breast cancer patients can prolong survival. So, pay attention to a balanced diet for the prevention of breast cancer has important practical significance.
First of all, it should be a reasonable diet. Different foods contain different types and quantities of nutrients. Variety of food per day should be diversified, with meat and vegetables, often exchange can ensure adequate nutrition, while avoiding the excess heat to control the fat, in particular the control of animal fat intake. Generally speaking, the calories provided by fat accounted for 20% of total calories diet to 25%. High-fat foods such as fatty meat, butter, duck and so on, make excessive caloric intake, causing obesity. The obesity is a risk factor for breast cancer-induced, it should be controlled, while conducting regular appropriate physical activity and physical activity can enhance physical fitness, burn calories and help weight loss.
Second, it is appropriate to eat with the anti-cancer effects of food. Epidemiological survey showed that eating soy can reduce the probability of breast cancer, tofu, dried tofu and other soy products are rich in quality protein, unsaturated fatty acids, inorganic salts and so on. Some experts pointed out that if intake of soy products a day of total quantities of food from 2% to 4%, it will play a protective effect on health. 1 to 3 boxes a month to eat tofu, the risk of breast cancer can be reduced by 50%. It should also be eating more fresh vegetables and fruit.
Of different vegetables, fruits, the nutritional composition and content is not exactly the same, shall be held alternately eating, vegetables, fruits, not only rich in vitamin C, carotene, inorganic salts and dietary fiber, also contain flavonoids, indole and aromatic iso – sulfur cyanide and so on, they all have a role in tumor suppression. Added iodine, selenium and other trace elements, optional water-rich fish, shrimp, oysters, jellyfish, garlic, onion, tomato, shepherd’s purse, kelp, mushrooms and a variety of dried fruits, appropriate more sun, can contribute to the body to produce more Active Vitamin D.
Do not eat, or eat with a carcinogenic or induced carcinogenesis food. Such as salted, smoked, fried and roasted food, during processing will generate some may have a carcinogenic effect or induced cancer substances, such as increased nitrite content in salted foods; smoked, fried and direct fire on the grill in a small food may have ring aromatic hydrocarbon polymers, such as benzopyrene category; cigarette burn can have a carcinogenic effect of nitro-compounds. Epidemiological survey found that passive smokers are more likely to suffer from breast cancer, persons with a history of passive smoking than those without the risk of disease is much greater, therefore, should avoid active and passive smoking.
