Health effects of soy protein

Abstract: Although soy protein is a plant protein, it has gradually attracted people’s attention due to its special amino acid content and special functional ingredients such as soy isoflavones. More and more clinical and experimental studies have confirmed that soy protein has a protective effect on the kidneys.

1 .With a low-fat diet, it helps to lower cholesterol

Studies have found that the consumption of soy protein can raise good cholesterol, inhibit the oxidation of bad cholesterol, remove junk fat on blood vessel walls, and improve blood vessel health.

In 1999, the US FDA (US Food and Drug Administration, an international medical review authority) issued an authoritative health statement: “Eating low-saturated fat and low-cholesterol foods containing 25 grams of soy protein every day can reduce the risk of cardiovascular disease. .”

Chinese residents’ dietary nutrition guidelines also specifically propose that we should pay attention to the intake of soybeans in our daily diet. People who have cardiovascular disease or have a tendency to develop disease should increase the intake of soy protein in their diet and reduce the intake of animal protein.

2 .Consistently eating it will help reduce the risk of certain cancers

People are more afraid of cancer than other diseases. Soy protein can reduce the risk of certain cancers. Studies have shown that eating soy protein food can reduce the incidence of breast cancer by 20%, reduce the incidence of prostate cancer by 35%, and reduce the incidence of gastrointestinal cancer by 30%. At the same time, it has a certain inhibitory effect on the occurrence of thyroid cancer.

3 .Unique sports nutrition value, it is a healthy food for dieters

Soy protein can help strengthen and maintain muscle mass, and can restore and relieve muscle soreness, redness and fatigue caused by exercise. It is a sports nutrition that reduces muscle soreness and fatigue and helps rapid recovery of physical strength.

As obesity is increasingly becoming a concern of modern people, compared with animal protein, soy protein can accelerate the use of stored fat in the body to provide energy, which is a very good healthy weight loss nutrition.

4 .Promote calcium absorption and utilization, improve bone health

Studies have found that large amounts of animal protein will increase the excretion of calcium by the kidneys. In a study conducted on 755 Japanese men and women, it was found that there was a significant proportional relationship between calcium excretion and animal protein intake, but this did not happen with soy protein intake.

The conclusion is: Compared with animal protein, soy protein does not increase calcium excretion, but promotes calcium absorption and utilization, prevents osteoporosis, improves bone density, and maintains bone health.

5 .Transport nutrients, enhance immunity and promote growth

Protein is the carrier and receptor of various nutrients such as calcium, iron and zinc, and can help the absorption and utilization of these nutrients. It can also enhance immunity and promote growth and development.

6 .Balance endocrine, alleviate related diseases

Lower the glycemic index of food, regulate glucose better than milk protein, enhance insulin sensitivity and promote glucose metabolism.

7 .Positive effects on the kidneys

Soy protein does not increase the burden of kidney metabolism (Kontessis, 1990). Soy protein can be accepted by patients with chronic kidney disease who require hemodialysis (stephenson et al., 2001). Soy protein is beneficial to the treatment and rehabilitation of type 2 diabetic patients with kidney disease.

Compared with casein, soy protein can reduce urine protein excretion more effectively, and the proteinuria excretion rate is inversely proportional to the plasma isoflavone level. The research suggests that in addition to essential amino acids, soy protein contains a variety of non-protein ingredients, such as soy isoflavones and soy peptides, which can improve kidney function and delay the progression of kidney disease.
