What are the benefits of soy protein isolate
Abstract: The intake of plant protein and animal protein should be basically the same, half each. Generally, plant protein has a higher content than animal protein, and has a wide range of sources and a large daily intake. And in the process of processing and production, the cost and technology are relatively easy and cheap.

The Chinese Nutrition Society’s recommendations for protein intake: 70-90g/day for adults; an additional 20g per day for pregnant women and an additional 25-30g per day for lactating mothers. World Health Organization (WHO) recommendations: 140g for men and 106g for women.
Both animal protein and plant protein are composed of amino acids, but their quality is different (depending on the content and ratio of essential amino acids). The human body has 8 kinds of amino acids that must be taken from food, which are called essential amino acids.
The quality of animal protein tends to be closer to the needs of the human body (after all, human beings are also an animal), and the absorption rate is higher, which is called high-quality protein or complete protein. And plant protein often lacks 1-2 kinds of essential amino acids (it does not mean that they are not at all, but the content is low, which is quite different from what the human body needs).
The intake of vegetable protein and animal protein should be basically the same, half each. Generally, plant protein has a higher content than animal protein, and has a wide range of sources and a large daily intake. And in the process of processing and production, the cost and technology are relatively easy and cheap.
As we all know, protein is hydrolyzed into amino acids by digestive juice, and amino acids are absorbed to produce protein needed by human body. Vegetarians can obtain healthy and strong bodies without supplementing animal protein, such as the monks of Shaolin Temple. Animal protein does not exist in the food sources of herbivores, but they tend to have larger bodies, such as dinosaurs, elephants, camels, cows, horses, and so on.
People often think that if animal food is not supplemented, malnutrition will be caused, which will induce a series of health problems. But facts have proved that this view is wrong. In addition, the latest scientific research in the United States shows that adults who grow up eating milk are far more likely to have allergies than adults who grow up breastfeeding.
Soybeans (including yellow soybeans, black soybeans, green soybeans, and edamame) are one of the few common plants rich in high-quality protein. In addition to methionine (matched with methionine-rich cereals to complement each other), the rest are essential The ratio of amino acids is in line with the needs of the human body, and the absorption rate is close to meat. Other non-animal foods rich in high-quality protein include quinoa and yeast. Soybeans are rich in high-quality protein like animal foods, but also contain milk and eggs. The nutritional characteristics (rich in calcium and phospholipids).
The protein content of soy protein isolate is more than 90%, there are nearly 20 kinds of amino acids, and it contains essential amino acids. It is rich in nutrition and does not contain cholesterol. It is one of the few varieties of plant protein that can replace animal protein.
Benefits and functions of soy protein isolate
With a low-fat diet, it helps to lower cholesterol
Cardiovascular disease is the number one killer of adults. The most direct cause is excessive intake of cholesterol in the diet. Studies have found that consuming soy protein isolate can reduce the concentration of cholesterol in the serum, increase good cholesterol, and inhibit the oxidation of bad cholesterol. , Remove junk fat on the blood vessel wall, improve blood vessel health. In 1999, the U.S. FDA 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. The Chinese residents’ dietary and nutrition guidelines also specifically propose that we should pay attention to the intake of soybeans in our daily diet. People who already have cardiovascular disease or those who are trending should increase the intake of soy protein isolate in their diets and reduce the intake of animal protein.
Consistently eat it, which helps 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 can 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%, reduce the incidence of prostate cancer in men by 35%, and reduce the incidence of gastrointestinal cancer by 30%. It also has a certain inhibitory effect on the occurrence of thyroid cancer.
With unique sports nutrition value, it is a healthy food for athletes and 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 relieves muscle soreness and fatigue, and helps to quickly recover physical strength. 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 healthy weight loss nutrition.
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 of 755 Japanese men and women, it was found that there is a significant proportional relationship between the amount of calcium excretion and the intake of animal protein, but intake Soy protein does not have such a situation. The conclusion is that compared with animal protein, soy protein does not increase calcium excretion, but instead promotes calcium absorption and utilization, prevents osteoporosis, improves 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, and can help the absorption and utilization of these nutrients. It can also enhance immunity and promote growth. Soy protein isolate is also beneficial to alleviate the number of hot flashes and the degree of reaction during menopause, and calm emotions.
The nutritional value of soy protein isolate
High protein: Whether for vegetarians or ordinary people, soy protein isolate powder is the perfect high-quality protein supplement.
Low-fat: For weight loss people who need a low-calorie diet, replacing part of the protein in the diet with soy protein not only reduces the intake of cholesterol and saturated fat, but also achieves a balanced nutritional intake.
Increase calcium: Soy protein can prevent urinary calcium loss, promote bone health, and reduce the risk of osteoporosis.
Lower cholesterol: Studies have shown that taking 25g of soy protein daily can effectively reduce the content of total cholesterol and low-density lipoprotein cholesterol in the human blood, thereby reducing the risk of heart disease.
No uncomfortable reaction: Soy protein isolate powder removes the original nutritional inhibitor trypsin inhibitor in soy, so you don’t need to have indigestion, flatulence and other uncomfortable reactions.
