Men who drink soy milk become more feminine

　　There are many opinions about soy milk in the market. For example, soy milk must be drunk fresh, and cold soy milk cannot be drunk. Drinking it will cause poisoning.； Men should not drink soy milk often. Drinking too much will cause female trend! Is that true? The reporter specifically asked nutrition experts.

　　1 Anecdotal opinion: Some people believe that soy milk is generally most nutritious when consumed within 2-3 hours. After that, the nutrients in soy milk will gradually decompose, and drinking it will easily cause bloating. diarrhea . Therefore, drink freshly ground soy milk!

　　Experts say: The third affiliated school of Sun Yat-sen University Hospital Bian Huawei, director of the Nutrition Department, said that currently, there is no evidence that the nutrients in soy milk will decompose after 2-3 hours. The sugars in soy milk will not turn into other substances, and calcium, iron, vitamins, etc. will not decompose under reasonable storage conditions. As for protein and fat, they will only cause bloating and diarrhea unless they go bad. This is a matter of food preservation safety, not decomposition.

　　Experts say that if it is freshly ground soy milk at home, it should be stored in the refrigerator at low temperature overnight, and it should be boiled again before drinking.

　　2 Anecdotal opinion: Soy milk must be drunk hot. Drinking cold soy milk will cause diarrhea.

　　Experts say: Soy milk is processed from soybeans. From a nutritional analysis, soybeans contain some anti-nutritional factors, such as trypsin inhibitors, lipoxygenase and phytoerythrocyte agglutinin. Drinking raw soy milk or uncooked soy milk may cause nausea, vomiting, stomach ache Gastrointestinal symptoms such as bloating and diarrhea, but these anti-nutritional factors can be eliminated by heat treatment. Therefore, raw soy milk must be boiled so that these harmful substances are completely destroyed before drinking. Therefore, it is not that you cannot drink cold soy milk, but that you cannot drink raw soy milk. Boiled soy milk is still safe to drink if it is cooled.

　　It should be noted that when soy milk is boiled to 80℃, a false boiling phenomenon will occur, and a lot of foam will be generated. At this time, many people mistakenly think that the soy milk has been boiled. In fact, it is necessary to continue boiling at this time. After boiling for another 3-5 minutes, the harmful substances in the soy milk can be completely destroyed.

　　3 Anecdotal opinion: Women should drink more soy milk to improve their beauty, while men should drink more soy milk to become more feminine!

　　Experts say: This view is based on the effect of isoflavones contained in soybeans. Soybean isoflavones have estrogen-like effects. Therefore, most people think that women eat beans and drink soy milk. skin Well, if men drink more soy milk, they may have a feminine tendency. Bian Huawei said that this is completely an incorrect inference.

　　First of all, although soybeans contain soy isoflavones, the content is not high and is far from enough to have a therapeutic effect. Therefore, the consumption of soybeans in daily life will definitely not lead to feminization in men. Used in adjuvant treatment of women disease Most of the time, purified soy isoflavones are used instead of soybeans themselves or soy milk.

　　The Chinese Nutrition Society believes that soybeans and soy products are rich in nutrients and have a variety of health benefits, especially for elderly It is a good food for cardiovascular patients. It is recommended that each person consume 40 grams of soybeans or soy products per day (equivalent to 4 taels of tofu or 800 grams of soy milk). This clearly shows that long-term consumption of soybeans and their products is good for male Both are beneficial and harmless to women.

　　Secondly, research shows that soy isoflavones can improve various menopausal symptoms, especially hot flashes and sweating symptoms. It has a similar effect to estrogen preparations, but it does not directly affect the level of estrogen in the relevant human body. In other words, the role of soy isoflavones in women is not to increase the amount of estrogen and improve symptoms of discomfort. Similarly, men who consume soy isoflavones will not have to worry about increased estrogen levels.

　　4. Anecdotal advice: Do not add brown sugar to soy milk, because the organic matter in brown sugar will combine with the protein in soy milk and form denatured precipitates that are harmful to the human body.

　　Experts say: In fact, brown sugar, white sugar or honey are all foods containing mainly disaccharides. There is no difference in principle. All three can be added. The key lies in the timing of addition. It is best not to add it when cooking soy milk. It is better to add it after it is cooled and ready to drink. Because during the heating process, the protein in soy milk can react chemically with sugar, producing substances that cannot be absorbed, resulting in a decrease in the nutritional value of soy milk.
