1. Eat more “white meat” and be cautious about taking supplements. According to statistics, more than 40% of adult women in China have different degrees of breast disease, and many of them do not have timely examination and treatment, which eventually leads to the development of breast cancer. In addition to regular checkups, you should also start your daily life, especially in terms of diet, to protect your breast health. 2. Do not eat palm oil and animal fat oil. To stay away from breast cancer, you’d better give up eating palm oil and animal fat oil, the fatty acids in these fats are mainly saturated fatty acids; in addition, don’t use hydrogenated processed oil or reuse fried vegetable oil, both of which will contain trans fatty acids. Saturated fatty acids and trans fatty acids are not good for breast health. 3, chicken, fish and other “white meat” is better. It is best for housewives to buy no or less bacon and bacon, and to cook without frying, deep-frying or baking, because these meats and cooking methods increase the risk of breast cancer. In addition, compared with beef, lamb, pork and other “red meat”, chicken, fish and other “white meat” are better sources of protein. Seafood such as sardines, tuna and shrimp not only provide protein, but also contain the trace element selenium. Selenium is commonly used as an antioxidant and has a significant anti-cancer effect. 4. Moderate intake of soy products. Some studies have pointed out that pre-menopausal women who consume a moderate amount of soy reduce the risk of breast cancer by 50%. Some studies also believe that if the consumption is too large (such as beans more than 100 grams per day), it will increase the burden of estrogen metabolism in the body. So how much is the “right amount”? The available evidence shows that a daily intake of 35 grams-60 grams of beans is appropriate. 5, eat cruciferous vegetables. Cruciferous vegetables such as wild mustard, cabbage, cabbage, broccoli, radish, mustard, etc. contain antioxidants, which can protect the body’s cells from free radical damage, but also help us eliminate pollution, speed up their own detoxification process, which helps to fight cancer. The top five vegetables with antioxidant effects are: garlic, cabbage, spinach, broccoli, and red bell pepper. In addition, asparagus, garlic, mushrooms, etc. also contain selenium, which has anti-cancer effects. 6.Eat more fruits. Fruits are rich in vitamin C. Vitamin C is also a common antioxidant. The top five fruits with antioxidant effects are: strawberries, plums, oranges, red grapes, kiwi. 7, appropriate intake of dairy products. A study involving more than 88,000 women showed a negative correlation between breast cancer risk and intake of low-fat dairy products, calcium (mainly from dairy products) and vitamin D in pre-menopausal women. This means that premenopausal women consuming low-fat dairy products may prevent breast cancer. According to the above study, it is recommended that pre-menopausal women should preferably drink skimmed dairy products, and post-menopausal women can drink any kind of dairy products. 8. Do not eat too much sugar. The kitchen at home should store less sugar, and usually eat less, especially white sugar. Eating too much sugar will increase fat, and being overweight will increase the risk of breast cancer in women. Oxford University has done the Million Women Study, postmenopausal women with a body mass index BMI ≥ 30 have a significantly increased risk of breast cancer. Obesity appears to be a manifestation of imbalance in fat metabolism, but the essence is an imbalance in the body’s internal environment, which will affect the body’s natural ability to fight tumors. Experts suggest that sugar can be consumed through fruits, vegetables and grains. 9. Be cautious about taking supplements. Many women often consume royal jelly, propolis, snow clams and placenta in order to maintain their beauty, but these supplements contain estrogen and it is best to eat less of them, otherwise they will increase the risk of breast cancer.
