Be careful! Women who drink more soy milk are more likely to develop breast cancer

　　For hundreds of years, Japan female breast cancer The incidence rate remains at 1/6 of American women, and the mortality rate is 1/3 of American women. The reason is that the soy diet plays a role that cannot be underestimated. Researchers at Georgetown University in the United States have proven through experiments that eating more soybeans can indeed prevent breast cancer, mainly due to the isoflavones contained in soybeans.

　　Soy isoflavones are an important type of phytoestrogens in soybeans. First of all, they can inhibit the activity of caseinate kinase that causes cancer cells. Secondly, they can control the proliferation of blood vessels on which cancer cells grow and slow down their growth. Thirdly, they can eliminate reactive oxygen species and play an antioxidant role. Finally, they can also regulate cell cycle, differentiation and apoptosis. Its estrogen-like effect can effectively reduce estrogen levels in the body, thereby reducing the occurrence of breast tumors.

　　As the only dietary source of soy isoflavones, soy protein can be consumed through tofu, soy milk, and soy milk.

　　However, researchers have also found that while soy isoflavones inhibit the growth of cancer cells, they can also become a "double-edged sword" if absorbed too much, making the amount of soy consumed every day very critical.

　　Preliminary data show that the optimal daily intake of isoflavones, which play a biological role in the human body, is 30-50 mg, which is equivalent to drinking at least one cup of 250 ml soy milk and eating 200-300 grams of soy products every day.

　　Although eating soybeans is indeed beneficial to the prevention of breast cancer, you should also pay attention to the way it is consumed. For example, it is best not to consume it in the form of powder. Generally speaking, unless you are really diagnosed with protein malnutrition or protein deficiency, it is enough to supplement soy isoflavones from your daily diet.

　　Nutritionists suggest that women with breast cancer risk factors should not consume large amounts of isoflavones or drink large amounts of soy milk for a long time. In addition, the protein in soybeans can hinder the body's absorption of iron. If soybeans or soybean products are consumed excessively, soybean protein can inhibit 90% of normal iron absorption, and people will suffer from iron deficiency symptoms such as fatigue and drowsiness in varying degrees. anemia symptom.

　　“Therefore, we should neither 'deify' soy milk nor talk about its discoloration. After all, long-term excessive intake will cause adverse effects. Most people will not have problems if they drink a small amount of soy milk normally. Adults can drink 1 to 2 times a day, 250 to 350 ml each time, and children can drink 200 to 230 ml each time. In general, soy milk is a good friend of mankind, but we should not overemphasize the special effects of a certain food, but should try to achieve a diverse and balanced diet. ”
