Isolate soy protein is a nutritional supplement that is useful for both athletes and people who want to diversify their diet with organic substances. It is distributed all over the world. In addition, soy isolate will appeal to vegetarians and people who are lactose intolerant. This universal product has not bypassed those believers who fast.
Soy protein isolate can be found in foods such as vegetable burgers, soups, power bars, breakfast cereals, and more. Since soy is a superfood, you can say isolated soy is good for you - right? But soy isolate is nothing but healthy, and can be downright dangerous. The reason has to do with how soy protein isolate is made.
Depending on who you ask, soy is either a superfood rich in protein and other nutrients, or a dangerous substance that will destroy your health. With such conflicting information, what should you think about soy? To help clear the air, here are some of the most popular myths and misconceptions about soy and the truth behind them.
During the day, a person needs to consume up to 2 grams of protein per 1 kilogram of weight. But in plant foods, the minimum content of macromolecular organic matter, therefore, during abstinence from certain foods, it is very difficult to restore the natural balance. The way out of the situation is soy protein isolate, about the effect of which on the body there are already myths.
Myth: Soy contains isoflavones, which can disrupt hormones.
This is the statement about soy that causes the most fear, especially among men. Anti-soy advocates say the isoflavones in soy, chemicals that are similar to estrogen, will cause estrogen-like effects and lower testosterone levels. You can often hear sufferers talking about how soy will shrink testicles, reduce sperm count and, if given to infants, may interfere with development.
Soy isoflavones can interfere with estrogen receptors, which is why soy is generally recommended to treat menopausal symptoms. But the soybean advocates are wrong here. They neglect to mention that there is more than one type of estrogen receptor in the body.
Soy Protein Myths
All the myths that have developed around the usefulness of soy protein have no scientific justification. And if you are told that soy lowers testosterone levels, you should not believe it. In addition, there is an opinion that this supplement is not completely absorbed in the body. This is possible if you use cheap soy protein isolates. Such a product will be absorbed only by 60%. Therefore, when choosing a nutritional supplement, you should choose only a quality product that will completely dissolve in your body.
Soy protein isolate for weight loss
In a meta-analysis of 50 treatment groups, researchers found that soy did not lower testosterone levels. However, soy is associated with numerous benefits for men. An analysis of 14 studies found that soy reduces the risk of prostate cancer.
Myth: Soy causes breast cancer.
This myth is also linked to concerns about soy isoflavones. Because soy acts on some estrogen receptors, people assumed it would have the same effect as estrogen supplements. But no study has ever found a positive association between breast cancer and soy isoflavones. Actually, it's true. Soy isoflavones may reduce the risk of breast cancer because they help regulate cell growth by blocking the negative effects of natural estrogen.
Plant proteins are said to have an amino acid composition that is not balanced. According to this myth, proteins from plant foods are incomplete. This is possible only in relation to other plant polypeptides. But this is not true if we are talking about quality soy isolate.
Cooking at home
You can make your own soy drinks using soy protein isolate, which can be purchased at any sports nutrition store. According to the standard 2 tbsp. l. additives are diluted in one glass of liquid. If you are using a weight loss product, you should pay attention to the calorie content. Athletes add fruits, nuts or oatmeal to vitamin mixtures. The result is a nutritious smoothie that helps the body recover from intense exercise.
Myth: Soy depletes nutrients from the body
It's easy to see where this myth comes from because soy contains anti-nutrients. Antinutrition is basically anything that blocks the absorption of nutrients. In the case of soy, the antinutrients are natural chemicals called phytates. Because phytates bind to certain minerals, they can prevent some iron, zinc, and calcium from being absorbed. The key word to note here is "some". You will still be absorbing significant amounts of these nutrients even when using phytic acid.
If you are using nutritional supplements for weight loss, then you should choose yogurts that contain a minimum of fat. You can use all kinds of fat-free products. But add nuts and bananas to vitamin cocktail Not recommended. For the basis of the recipe, you can take yogurt or kefir. You can prepare a cocktail in a few minutes. You will need soy protein isolate, the recipes for which are quite simple. Namely, 25 grams of food additives are mixed with juice or water for 180 ml. Remember that you should drink a drink half an hour before training and after training in the gym for 20 minutes. You should not abuse and take soy isolates constantly, it is better to do it cyclically.
The phytic acid in soy does not deplete nutrients from your body in any way. It is important to note that soy is very high in all of these nutrients that are supposedly blocked. So while you may not be absorbing all of the 8mg of iron found in a cup soybeans you still get a lot of iron.
Myth: Soy prevents heart disease.
Soy is considered a healthy food. it high content fiber, which can help lower cholesterol levels. Soy also promotes the production of natural chemical nitric oxide. Nitric oxide dilates blood vessels, which can reduce arterial pressure. However, simply adding soy to your diet will not prevent or cure heart disease. If you are not eating a healthy, well-balanced diet with low content saturated fat, then soy won't do you much good.
Useful properties of soy product
To useful properties The product should be attributed to the fact that soy protein isolates in their composition have a number of natural plant components. In addition, the food supplement increases the body's production of inorganic binary compounds of nitrogen and oxygen, which improve blood flow in the muscles, which has a beneficial effect on the general well-being of sports fans. Regular consumption of soy protein in combination with healthy eating has a positive effect on the overall metabolism. And also it minimizes the risk of developing heart disease, which is possible with a lack of oxygen.
How is soy protein isolate made?
If obesity causes heart problems, learn more about it. By definition, soy protein isolate makes up at least 90% of the protein from soybeans. Have you ever stopped and wondered how they separate protein from beans to isolate? The defatted soybeans are then soaked in ethanol or acidic water to remove carbohydrates and aromatics. The result is a substance that is 90% protein and can be added to foods to increase the protein content.
Not all soy isolates are made from hexane. It is also possible to make soy isolate using machines that extract oil from soy. Before you worry about the health risks of soy foods, know that foods made with whole soy — like tofu and tempeh — don't use hexane. All soybeans are produced for cooking.

What happens if all this hexane residue ends up in our bodies? The idea is that hexane floating around in oil refineries is dangerous to workers who can breathe it in. Yes, breathing hexane particles will probably be much worse than digestion. small quantities leftovers. And I have yet to find any research that looks at the health effects associated with hexane consumption. However, it is not encouraging that almost all of the studies that have found Negative consequences for health with soy products were conducted using soy isolates.

Although the sex hormone is often considered to be exclusively sex-specific, clinical evidence suggests that a balance of both hormones is needed, with testosterone predominating in men and estrogen predominating in women.
