In 1999, the US FDA issued an authoritative health statement: Eating foods low in saturated fat and cholesterol containing 25 grams of soy protein per day can reduce the risk of cardiovascular disease. The dietary nutrition guidelines for Chinese residents also specifically propose that we should pay attention to the intake of soybeans in our daily diet. People with pre-existing cardiovascular disease or those who are developing should increase the intake of soy protein isolate and reduce the intake of animal protein in their diet.
Consistent consumption can help reduce the risk of certain cancers
Although a large number of people die from cardiovascular disease, people in general are more afraid of cancer. Soy protein may reduce the risk of certain cancers. Studies have shown that eating soy protein food can reduce the incidence of breast cancer in women by 20%, the incidence of prostate cancer in men by 35%, and the incidence of gastrointestinal cancer by 30%. At the same time, it also has a certain inhibitory effect on the occurrence of thyroid cancer.
With unique sports nutritional value, it is a healthy food for athletes and dieters
Soy protein can help build and maintain muscle mass, as well as restore and relieve muscle soreness, redness, and fatigue from exercise. It is a sports nutrition that relieves muscle soreness and fatigue and helps to recover quickly.
Today, obesity has increasingly become a concern of modern people. Compared with animal protein, soy protein can promote the secretion of glucagon and accelerate the use of stored fat in the body to provide energy. It is a very good nutrition for healthy weight loss.
Promote calcium absorption and utilization, improve bone health
Studies have found that a large intake of animal protein will increase the excretion of calcium by the kidneys. In a study of 755 Japanese men and women, it was found that there was a significant positive relationship between calcium excretion and animal protein intake, but intake This is not the case with soy protein. The conclusion is that compared with animal protein, soybean protein does not increase calcium excretion, but promotes calcium absorption and utilization, prevents osteoporosis, increases bone density, and maintains bone health.
Transport nutrients, balance endocrine
Protein is the carrier and receptor of various nutrients such as calcium, iron and zinc, which can help the absorption and utilization of these nutrients. It can also enhance immunity and promote growth. Soy protein isolate is also beneficial to relieve the number and degree of hot flashes during menopause, and to calm emotions.
How is animal protein different from soy protein?
Animal protein is rich in a variety of essential amino acids and is an important source of high-quality protein, but the food source of animal protein is also rich in fat and cholesterol, which is an important reason for the high incidence of various chronic diseases in modern people.
Soy protein is the only “complete protein” from plant sources. The so-called “complete protein” means that it can provide the human body with all-round essential amino acids, and the ratio of these amino acids is also in a good balance, which can meet the health needs of the human body.
Speaking of this, we also need to understand the concepts of the following terms, because there are many kinds of proteins also derived from soybeans, such as soybean flour, soybean protein concentrate and soybean protein isolate, and they are very different.
Soybean meal: Made from whole-fat soybean meal ground into a powder. Soy flour is the least refined of the three main soy protein ingredients.
Soy Protein Concentrate: A processed product that removes most of the sugar but retains most of the soy fiber. The processing of soy protein concentrate affects the retention of many of its bioactive components.
Soy protein isolate: It is the best in soy protein processing to retain the healthy active ingredients of soy. The soybean protein isolate separated by special technology has a complete range of amino acids, and removes the ingredients that are not conducive to absorption and health in soybeans such as inhibitory protein factors and purines. The biological potency is the same as that of eggs and milk, and the quality is better than that of beef. Soy protein isolate is the most essential part of the protein processing process.
What kind of protein is high-quality protein?
If the human body is compared to a house, protein is the building block of a house and an important material basis for all tissue cells in the body. Therefore, protein as a raw material must be of high quality.
Three criteria for selecting high-quality protein: PDCAAS=1, high protein content, low fat and low cholesterol. Different food sources of protein, because of their different types and proportions, have different digestion and absorption rates in the human body. Therefore, nutrition scientists like to use PDCAAS to measure the digestibility and absorption rate of protein. Only when the PDCAAS is close to 1 or equal to 1, can it be awarded the honorable title of high-quality protein.
