Soy protein has recently been a fairly popular nutritional supplement. It is often recommended by nutritionists. But any protein is especially popular with athletes.
It is worth noting that not everyone considers the soybean option effective. After all, its biological value is very small. In contrast to soy, there is whey protein and a whole egg. They are something that is preferred by athletes who need to gain weight.
Soy protein. Harm
Due to some of the disadvantages of this dietary supplement, it is completely avoided. The reason for this is the insufficient content of methionine in it, which is a sulfur-containing acid. This component plays a very serious role in maintaining human immunity. Thanks to methionine, glutathione is also produced. It, in turn, is an important antioxidant. This substance performs a number of significant functions:
- Protects body cells from harmful compounds, and also removes them;
- Prevents cholesterol oxidation.
In this regard, we can conclude that soy protein is less effective and beneficial for the body in terms of maintaining the immune system.
There is also an opinion that this supplement not only does not lower blood cholesterol, but, on the contrary, increases it. And this is a threat to the occurrence of atherosclerosis. This applies to soy protein if it is not further enriched in methionine.
This is not the only negative of such a protein. In addition to everything, it contains dangerous components that can interfere with normal digestion. They also slow down the body's absorption of essential and very important nutrients. So, these components are:
- Lectin. This plant substance is very dangerous for human health. Its use can lead to damage to the stomach and intestines.
- Protease. An enzyme that is actively involved in the digestion of all proteins. At the same time, it significantly disrupts the function of other enzymes that help to absorb nutrients and proteins.
- Estrogen. These substances inevitably lead to the formation of fat.
Soy protein. Advantages
After the negative sides, it seems that soy can’t even have anything positive. However, this is not at all true. Many harmful substances that a food supplement contains are removed during the manufacturing process. In this case, the protein is saturated with methionine. This allows you to add value to such a product.
In the course of numerous studies, it was found that soy protein has the ability to reduce the number of cancer cells that are dangerous to human life. Often, doctors even prescribe the use of this supplement as one of the treatments for cancer.
Recommended protein (soy) is also for patients with problems of the cardiovascular system. The fact is that the risk of heart disease, the use of this supplement significantly reduces. At the same time, there are no effects on the reproductive system of the body.
Scientists have long established the fact that soy protein has a beneficial effect on the thyroid gland, restoring its normal functioning. Taking this supplement helps to increase the production of thyroid hormones. And this property is unique.
Soy Protein
For many, the dilemma is whether it is worth taking this supplement or not. After all, it is harmful on the one hand, and on the other, it has many positive aspects. The answer is very simple. You can consume a small amount of such protein. Nutritionists even recommend using no more than 30 g of product per day.
And most people mix 2 different proteins, benefiting from one and the other together. Moreover, today there is no reason to believe that the use of several types of protein simultaneously leads to the loss of their properties.
It is standardly recommended to take 30g of soy protein per day diluted with a warm liquid. For such an amount of additive, 300 ml of milk or plain water is enough.
