The study found a significantly higher incidence of breast cancer among Chinese women who immigrated to the United States. This phenomenon of increased incidence to post-immigration levels after immigrating from a low incidence country to a high incidence country suggests that these changes are more likely due to life circumstances than genetic factors. Let’s learn how to improve nutritional patterns and reduce breast cancer risk today! 1. Increase intake of dairy products, calcium, vitamin D and lactose A 16-year follow-up cohort study conducted by Myung-Hee Shin on 3482 women suggested that for postmenopausal women, intake of dairy products, calcium and vitamin D were not statistically associated with breast cancer risk; however, dairy products, especially low-fat or nonfat milk or dairy products, could reduce the risk of breast cancer in premenopausal women. However, dairy products, especially low-fat or nonfat milk or dairy products, can reduce the risk of breast cancer in premenopausal women. 2. Moderate consumption of tea, decaffeinated coffee and coffee The results of various studies on whether tea, coffee and decaffeinated coffee consumption increase the incidence of breast cancer are inconsistent. The Fagherazzi team conducted an 11-year prospective cohort study of 67,703 French women, and the results showed no correlation between the intake of these three beverages and the occurrence of breast cancer. Another prospective cohort study of 85,987 U.S. women over 22 years showed that tea and decaffeinated coffee intake were not associated with breast cancer risk, and that heavy coffee consumption in postmenopausal women reduced breast cancer risk. A Meta-analysis of Chinese women showed that regular tea consumption and regular exercise significantly reduced the incidence of breast cancer. 3.Increase the intake of soy products A study conducted by the University of Southern California Preventive Medicine on the intake of soy products found that a high intake of soy products during adolescence and adulthood can reduce the incidence of breast cancer in Asian Americans. 4.Increasing the intake of fruits and vegetables, fish and cereals Ataollahi analyzed the nutrition and health behavior of breast cancer patients and healthy women in her center, showing that the diet structure of breast cancer patients is not balanced compared with healthy women, and the intake of fruits and vegetables, fish and cereals is significantly lower than healthy women, suggesting that a healthy and balanced diet structure is important for breast cancer prevention.
