Protein in soybeans

Protein in soybeans

Protein in soybeans, protein is a complex organic compound, the old name "prion". There are many protein-rich foods around us, such as soybeans, soybeans are one of the protein-containing foods, so you know how much protein in soybeans

Protein in soybeans1

The protein content of soybeans is about 40%.

Soybeans contain about 20% fat, about 40% protein, but also rich in vitamins, soybean nutrition is comprehensive and rich in content, which is 2 times higher than the protein content of pork, is 2, 5 times the egg content. Protein content is not only high, but also good quality. The amino acid composition of soy protein and animal protein is similar, in which the amino acids are closer to the ratio of human needs, so it is easy to be digested and absorbed.

Nutritional value of soybeans:

1, through the guide stools: The soluble fiber contained in soybeans can be used to not only pass stools, but also reduce the cholesterol content;

2, lowering the sugar, lowering the fat: Soybeans contain a substance that inhibits pancreatic enzymes and has a therapeutic effect on diabetes. Saponins contained in soybeans have an obvious hypolipidemic effect, at the same time, can inhibit weight gain;

3, soybean isoflavones is a structure and estrogen similar to estrogen, with estrogenic activity of the phytoestrogens, can alleviate the symptoms of female menopausal syndrome, delayed aging of women's cells, so that the skin to maintain elasticity, nourish the face, reduce bone loss, promote bone The main reason for this is the fact that it can be used to reduce the risk of cancer and to improve the quality of life of women.

4, enhance the immune function: yellow soybeans are rich in protein, contains a variety of essential amino acids, can improve the body's immune system;

5, to prevent vascular sclerosis: lecithin in the soybean can be removed from the cholesterol attached to the wall of the blood vessels, to prevent vascular sclerosis, to prevent cardiovascular disease, protect the heart. Prevent cardiovascular disease, protect the heart. Lecithin in soybean also has the role of preventing the liver from accumulating excessive fat, thus effectively preventing and controlling fatty liver caused by obesity.

A soybean protein content is how much

Soybeans are high-protein food, every 100 grams of soybeans containing protein 35,1 grams (35,1%), is the most protein-rich grain crops. Other grain crops, such as wheat (Longmai) for 12, 0%, rice for 7, 4%, corn (yellow) for 8, 7%, millet for 11, 6%, raising wheat for 9, 3%, oats for 15%, sorghum rice for 10, 4%, far inferior to soybean. Soybean products, such as dry basis calculation, the protein content will reach 50% or more, and animal food, so known as "plant meat".

Second, soybean other nutrients

1, soybean's 'fat content

soybean fat 16, 0%, some varieties of up to 20% -25%. Soybean oil is mostly composed of unsaturated fatty acids oil, in addition to providing the body with essential calories, but also very good nutritional health effects. Unsaturated fatty acids constitute soybean oil is mainly oleic acid, linoleic acid, linolenic acid and a small amount of arachidonic acid, of which linoleic acid is an essential fatty acid. The so-called essential fatty acids, is necessary for the body, the body can not be synthesized, must be food intake of polyunsaturated fatty acids. Soybean oil has a linoleic acid content of 50 to 8 percent, which meets the needs of human health.

2, soybean trace element content

soybean is also rich in inorganic salts and trace elements, especially calcium, phosphorus, potassium content. In addition, there are iron, sodium, magnesium, manganese, zinc, aluminum, etc., the traditional tofu production using brine (magnesium chloride), so the tofu in magnesium, chlorine content is also very high, these elements have important physiological functions.

The content of vitamin e in soybeans is about 18, 90 mg / 100 grams, far more than all cereals. Vitamin e is able to fight infertility, antioxidant, maintain the integrity of red blood cells, regulate the body dna biosynthesis, dietary vitamin e is the main source of soybeans.

Protein in soybeans3

A, which food protein content

1, animal food protein content

Livestock

Livestock protein content in 10% to 20%

between 10% and 20%, most of which is found in the muscle tissue. Beef and lamb have higher protein amounts, up to 20%; pork is lower, with an average protein content of 13.2%.

Poultry meat

Poultry meat has a protein content of about 16% to 20% protein content, comparable to red meat. Among them, chicken meat has the highest content, followed by goose meat, duck meat is relatively low. If you want to lose weight, don't eat the skin, the fat is all in the skin.

Fish, shrimp, crab, shellfish

Fish, shrimp, crab, shellfish and other aquatic products, protein content of 15% to 22%, and the fat content of fish is less, mainly composed of polyunsaturated fatty acids, polyunsaturated fatty acids in marine fish (such as EPA and DHA) can lower blood lipids, to prevent atherosclerosis

Eggs

Egg protein is almost the most ideal protein in natural food, almost completely digested, absorbed and utilized by the body, their protein content is 14.8%.

Milk

is a nutrient-rich food, the protein content of about 2.8 to 3.4%, its amino acid content and proportion of human needs, digestibility of up to 98% to 100%, is in addition to eggs the best complete protein.

2, plant protein

beans

Beans and their products are generally in the protein content of 20% to 40%, of which the soybean protein content of up to 30% to 40%, and the quality of better.

In addition to protein, soybeans are also rich in unsaturated fatty acids, calcium, potassium, and vitamin E, as well as soy isoflavones, phytosterols, soybean oligosaccharides and so on, can prevent osteoporosis, improve the symptoms of female menopause, reduce the incidence of cardiovascular disease.

Vegetables and fruits

Vegetables and fruits are extremely low in protein (generally no more than 2%), but vegetables and fruits are rich in vitamin C and minerals such as calcium, sodium, potassium, magnesium and other elements, as well as a certain amount of carbohydrates, mainly sugar, starch, cellulose and pectin.

Nuts

In addition, nuts also contain protein, but also rich in fat, especially containing omega-3 fatty acids, as well as iron, zinc, calcium, magnesium and other minerals, vitamin E, B vitamins, as well as polyphenols and so on phytochemicals, nuts inside the dietary fiber is also quite rich, moderate intake of nuts There are benefits to blood lipids and cardiovascular health.
