As the ancients once said, “Food is the sky”, which fully illustrates that eating is the top priority in life. At the same time, people eating grains and cereals inevitably suffer from a variety of diseases. Doctors are concerned about diet, not only because disease comes from the mouth, but also because diet can prevent disease. Asian women are less likely to suffer from breast cancer than women in Western countries, and this is inextricably linked to diet. As the saying goes, medicine is better than food. So how can we prevent breast cancer from diet? 1. To develop good dietary habits. It is important to have a reasonable diet, reduce the intake of high-fat and high-calorie foods, especially fried foods and sweets, stay away from smoking and alcohol, and maintain a normal weight as much as possible. 2, pay attention to the collocation of coarse and fine grains. Coarse grains are rich in fiber, which can promote intestinal peristalsis to help detoxify the body and reduce the concentration of low-density cholesterol and triglycerides. 3, to eat more fresh fruits and vegetables. Fresh fruits and vegetables are rich in vitamins, minerals and dietary fiber, which can effectively help antioxidants and help the body resist various diseases including breast cancer, especially more cruciferous vegetables (including bok choy, cabbage, cauliflower, broccoli, etc.). Other foods including soy products, nuts, seaweed, garlic, etc. are good choices. It is important to eat about 500 grams of vegetables a day, and it is best to have more than 5 types, with some dark greens, carrots, mushrooms, beans, etc. This may be difficult for busy working people to do, as it is often difficult to ensure the intake of vegetables in the daily fast food, so it is better to prepare a little vegetable salad for yourself every day. Cancer prevention is a big issue, and diet is not a trivial matter, so please start to develop good daily habits from now on.
