Mediterranean diet, some observational studies suggest that Mediterranean diet may be able to reduce the incidence of breast, and a recent randomized study published in jama suggests that Mediterranean diet with extra virgin olive oil is beneficial for breast cancer prevention, but because of the limitations of the study, long-term and extensive research is needed to confirm. The Mediterranean diet refers to a style of eating based on vegetables, fruits, fish, grains, legumes and olive oil in the countries of southern Europe, such as Greece, Spain, France and southern Italy, which are located along the Mediterranean Sea. The Mediterranean Diet Pyramid Reducing fat and red meat intake: Overweight, obesity and weight gain are all associated with postmenopausal breast cancer. A study in this year’s Journal of the National Cancer Institute showed that a high-fat diet increases the risk of breast cancer, most notably, high saturated fat intake increases the risk of receptor-positive disease, suggesting that saturated fat is associated with the etiology of receptor-positive breast cancer. According to a report released by the WHO International Agency for Research on Cancer on October 26, intake of processed meats can increase the risk of cancer in individuals to an extent comparable to that of smoking. Although it is mainly seen in rectal cancer, further research is needed to determine whether it is related to breast cancer. Intake of vitamins, minerals, and trace elements Intake of vitamin D: Studies have shown that high levels of vitamin D and calcium intake significantly reduce the risk of breast cancer in women, and that serum levels of 25-hydroxyvitamin D (25(OH)D) and breast cancer risk are significantly negatively correlated, while serum levels of the active form of vitamin D, 1α,25-dihydroxyvitamin D (1α,25(OH)2D ) levels were not associated with the risk of breast cancer. Women should take care to get enough vitamin D and calcium in their daily life through nutritious diet and more sun exposure to reduce the risk of breast cancer. Vegetables and fruits: There are related studies suggesting that broccoli may reduce the risk of breast cancer. Phytoestrogens and soy: Soy does not increase the risk of breast cancer, but may have its important role in breast cancer prevention. For breast cancer patients, soy can reduce the risk of recurrence and death. High-fiber foods: Studies have shown that a high-fiber diet may reduce the risk of breast cancer. Foods traditionally rich in fiber include bran, corn, brown rice, soy, oats, buckwheat, wild rice, celery, bitter melon, and fruits. Reducing alcohol intake reduces the risk of breast cancer, especially for ER+/PR+ invasive lobular carcinoma. Maintaining a healthy diet, although not specific for reducing breast cancer risk, is still very important for women. Good lifestyle habits are the cornerstone of good health!
