The positive effects of soy protein isolate on health

Soy protein isolate is obtained by removing soybean oil and water-soluble non-protein parts from dehulled soybeans using high technology. Its protein purity is extremely high and it is the main base material for protein powder foods that have become popular all over the world in recent years.

The main advantages of soy protein isolate are:

1.Compared with other proteins, it has the highest biological value for digestion and absorption in the body, and the digestibility of soy protein isolate is 93% to 97%;
2.It can effectively replenish immune cells in the body, produce antibodies for the immune system to fight bacteria and infections, and enhance the body’s disease resistance;
3.It can help the body create new tissue to replace damaged tissue, transport various nutrients to cells, and produce enzymes in the body, which helps convert food into energy. Protein is a necessary raw material for making enzymes in the body. Without enzymes, biochemistry cannot be carried out. reaction, it cannot be metabolized.
4.Soy protein is rich in essential amino acids, high in unsaturated fatty acids, and rich in nutrients. At present, the food industry around the world is extracting more protein from soybeans. Foods made with soybean protein have low fat and cholesterol contents and do not contain lactose, which can easily cause diarrhea.
5.Suitable for all kinds of people, especially people who are in sub-health, weak constitution and growth and development stages and need to supplement a lot of protein (such as people recovering from injury or surgery, as well as pregnant women, lactating women, developing teenagers, vegetarians and the elderly) etc.); it is also suitable to be made into health food and added to the meals of children, the elderly, dieters and various groups of people.

The positive effects of soy protein isolate on health mainly include:

1.Soy protein isolate can help reduce plasma cholesterol levels, which has been confirmed by a large amount of evidence. Consuming 47 grams of soy protein per day can reduce low-density lipoprotein (LDL) cholesterol, total cholesterol, and triglycerides in the blood without reducing high-density lipoprotein (HDL) cholesterol. For people with high cholesterol levels, as long as 25 grams of soy protein per day can have obvious effects. Since high plasma cholesterol is the main factor leading to heart disease and atherosclerosis, soy protein plays an important role in preventing and treating cardiovascular disease and ensuring heart health.
2.Soy protein isolate can prevent urinary calcium loss and help promote bone health. Animal protein is rich in sulfur-containing amino acids, which will accelerate the loss of calcium in the urine and lead to a negative calcium balance in the body. The content of sulfur-containing amino acids in soybeans is relatively low, and it causes the least loss of calcium in the urine among all high-protein foods. Animal experiments have proven that consuming soy protein can prevent bone loss, thereby reducing the risk of osteoporosis.
3.The intake of soy protein isolate has the effect of promoting kidney function. In experiments on animals suffering from kidney disease, it was found that the test group that consumed soy protein food had a higher survival rate and a lower degree of kidney damage. Some studies have pointed out that patients with kidney disease can achieve the same effect by consuming soy protein and protein-restricted foods. In other words, soy protein can be used as a relatively safe source of protein for patients with kidney disease.
4.Soy protein isolate can be used to regulate menstrual cycles in premenstrual women, an effect that may reduce the incidence of breast cancer. A long-term dietary study confirmed that people who eat a lot of soy foods have a reduced chance of developing breast cancer. Eating soy protein has shown positive effects in several aspects of health. The mechanisms of some effects are still under study. Experiments have found that soy protein and isoflavones are needed in some aspects.
