What is soya useful for the body of women and men

What are the advantages of soy for the human body? Initially, I would like to note the huge amount of protein in 100 g of the product. Vegetable protein differs from animal protein in that it does not contain cholesterol, and it is perfectly absorbed in the human body. Thanks to this feature, the grain is a great substitute for meat and fish, which is very important for vegetarians.

Here are a few more health benefits:

  • Soy is able to remove bad cholesterol. Lecithin helps in this. To feel the result, you need to consume at least 25 g of soy every day. Or it can be replaced with powdered soy protein, mixing it with oatmeal or stirring it with low-fat milk.
  • Due to the presence of polyunsaturated fats, dietary fiber, vitamins and minerals, the use of soy makes it possible to reduce the risk of cardiovascular diseases.

It is useful to know that the phytic acids contained in these beans help to make the treatment of heart and vascular diseases more effective. Use soy is recommended for rehabilitation after heart attacks, as well as for atherosclerosis, hypertension and coronary heart disease.

  • These beans protect against cancer. Isoflavones, phytic acids, and antioxidants prevent the development of cancer cells. They prolong the menstrual cycle and reduce the production of the hormone estrogen in the blood.

It is useful to know: soy can rightly be called an analogue of chemical drugs designed to fight cancer. The beans contain an organic substance called genistein. It acts as an antioxidant and antihelminthic agent. In its structure, the material is similar to the hormone estrogen. It interacts with estrogen receptors, stopping the development of prostate, colon, breast, ovarian, and endometrial tumors in the early stages.

  • The benefits of soy for women’s bodies is that it helps fight the symptoms of menopause, osteoporosis and hot flashes. Thanks to calcium and replacement of estrogens with plant components, a woman’s well-being is significantly improved.
  • Soy is very important for weight loss. Although the number of calories in it is quite large, eat a lot of grains still will not work, as it quickly saturates the body. In addition, its use begins to actively burn fat in the liver and improves metabolic processes, due to the presence of lecithin. This substance also performs the function of a choleretic drug.
  • The benefit of soy for men is that these beans are a source of proteins with anabolic amino acids. They protect against the destruction of proteins that are found in the muscles. And estrogens of natural origin help to increase muscle mass, which is very important for athletes.

What is harmful to soy for the body, and what are the contraindications to its use

What is harmful to soy for the body, and what are the contraindications to its useAnd now let’s look at what is often said in the media — what is harmful to soy. There are many theories on this subject, and some of them have been tested by scientists. For example, one theory is that frequent soy consumption can cause Alzheimer’s disease. Scientists have investigated this issue and found that men who used soy tofu for a long time had more mental disabilities.

It is also believed that soy acts as an oral contraceptive, and that it can subsequently cause infertility. Therefore, it can not be used by pregnant women. It is difficult to confirm or challenge these theories.

As for GMO, many claim that modified varieties are treated with a special poison called glyphosate. It eliminates weeds and, as some believe, remains in the beans and poisons the person. However, there have been many studies that have found that there is nothing to be afraid of.

Although it is difficult to draw unambiguous conclusions about genetically modified soy, it is worth remembering that the homeland of this modified product is America, where it has been used for 20 years. At the moment, the picture is as follows: almost every third child is obese, and many suffer from allergies. But there is no evidence that this is caused by modified products.

So, use soy or not, you decide. On the one hand, it has a positive effect on health, on the other-it can be dangerous for those who want to get pregnant, who suffer from diseases associated with the endocrine system, and who are in old age. But even if you are very fond of this product, use it in a moderate amount no more than three times for 7 days and no more than 150 g per day.
