The occurrence of breast cancer is related to many factors such as diet, genes, environment, and stress. For individuals, genes are established and the environment is relatively certain, the role of dietary factors in the prevention and improvement of breast cancer is particularly important.
What factors can prevent breast cancer or improve breast cancer prognosis?
1. Stay away from obesity
Obesity increases the risk of developing breast cancer and is also a poor prognostic factor for breast cancer. Controlling calorie intake is an effective way to deal with obesity. A low-fat, low-calorie diet structure has a positive impact on the prevention and treatment of breast cancer.
2.Vitamin D
Vitamin D can reduce the risk of breast cancer and can inhibit the growth of tumor cells, which has a positive effect on the recovery of breast cancer. Foods rich in vitamin D mainly include sea fish, animal liver, egg yolk, lean meat and skimmed milk.
3.EPA, DHA
EPA and DHA are both members of the omega-3 polyunsaturated fatty acid family. The content of fatty acids in breast adipose tissue is closely related to the occurrence of breast cancer, and dietary fat intake will affect the formation of fatty acids in adipose tissue. The current dietary habits of Chinese residents are dominated by the intake of ω-6 polyunsaturated fatty acids, and experiments have shown that the growth of breast cancer cells can be inhibited when the ratio of ω-3 and ω-6 polyunsaturated fatty acids is 1:1.
Therefore, for breast cancer patients and breast cancer susceptible people, they should increase the intake of ω-3 polyunsaturated fatty acids and eat more foods rich in ω-3 polyunsaturated fatty acids such as deep-sea fish.
EPA is the abbreviation of Eicosapentaenoic Acid and DHA is the abbreviation of Docosahexaenoic Acid.
DHA stands for Docosahexaenoic Acid. The two are the main components of fish oil, both belong to the ω-3 series of polyunsaturated fatty acids, is the body itself can not be synthesized but indispensable important nutrients, also known as essential fatty acids.
4.Reduce red meat intake
Excessive intake of red meat such as pork, beef and sheep can easily lead to excessive dietary calorie and fat intake, increasing the risk of breast cancer.
5. Drink alcohol in moderation
Excessive alcohol consumption can increase the risk of breast cancer and is not good for the prognosis of breast cancer. The stimulation of alcohol will promote the production of breast vascular tumors and affect the immune system, leading to abnormal secretion of estrogen and other hormones. Moreover, the metabolites of alcohol in the body can also promote the growth of breast cancer cells. Therefore, the amount of alcohol consumption should be controlled in daily life.
Five elements of a healthy breast cancer diet that you must know!
If eating a food can cure or prevent the occurrence of breast cancer, it is not a food, but a medicine. In order to ensure breast health, three meals a day should adhere to a low-fat, low-calorie dietary structure with a variety of small amounts, more vegetables and less meat, which can be summarized into the following five elements.
1, coarse and fine grains with food
Mixed grains (oats, buckwheat, brown rice, etc.) are rich in dietary fiber, which can reduce the incidence of breast cancer, but also reduce the absorption rate of fat in the diet, which also has a positive effect on weight loss.
2, fresh vegetables and mushrooms in large quantities
Fresh vegetables and mushrooms are not only rich in dietary fiber, but also rich in vitamins and plant compounds, which can effectively prevent the occurrence of cancer and inhibit the growth of tumor cells.
3.Adequate increase of deep-sea fish
Deep-sea fish is rich in polyunsaturated fatty acids such as DHA and EPA, but the current per capita daily intake of Chinese adults is only 37.6mg, which is less than 1/4 of the value recommended by the US Institute of Medicine, and is seriously deficient (the amount recommended by the US Institute of Medicine is 160mg/day).
Deep-sea fish including cod, sardines, salmon, tuna, swordfish, sea eel, yellowtail, pomfret, anchovy, etc.
4, soy products daily consumption
Soybeans and soy products contain phytoestrogens such as soy isoflavones, which can regulate the level of estrogen in the body in both directions, inhibit the growth of tumor cells, antioxidants and other effects, so do not refuse to eat soy products simply because of the estrogen-like substances in soybeans. The recommended daily intake of soybeans in the “Balanced Diet for Chinese Residents” is 30-50g. 40g of soybeans is equivalent to: 80g of dried soybeans, or 120g of northern tofu, or 240g of southern tofu, or 280g of lactic tofu, or 650g of soy milk.
5, a small amount of nuts for snacks
Nuts are the best part of the plant, containing unsaturated fatty acids, vitamins and minerals beneficial to the human body, the growth and development of women, enhance physical fitness, disease prevention has a very good role. Due to the high calorie content, it is recommended that moderate intake.
