3. It has a strong lactation function, is rich in phosphorus and calcium, and is beneficial to children and pregnant women;
Scientists recently found that it helps to eliminate the "jet lag" caused by jet lag.
Nutritional components and health functions of black beans Black beans are also called fermented beans and black beans.
Black beans have the characteristics of high protein and low calorie, with black skin and green inside.
So what are the nutrients of black beans? Next, I'll take you to know about it.
Nutritional components of black beans
1, protein
Black beans have the characteristics of high protein and low calorie, and the protein content is as high as 45%.
Among them, high-quality protein is about 1/4 higher than soybean, ranking first among all kinds of beans, so it has the reputation of "king of beans".
Compared with protein's abundant meat, black beans are not inferior, even better. Its protein content is twice that of meat (pork and chicken), three times that of eggs and 12 times that of milk, so it is also called "vegetable protein meat".
2. Fatty acids
It was found that every 100g of black beans contained more than 12g of crude fat.
It is found that it contains at least 19 fatty acids, and the content of unsaturated fatty acids is as high as 80%, of which linoleic acid accounts for about 55.08%.
Linoleic acid, as an unsaturated fatty acid, is a very important essential fatty acid in human body and plays a vital role in regulating cholesterol metabolism. Only when cholesterol is combined with linoleic acid can it be transported in the body and metabolized normally.
When linoleic acid is deficient, cholesterol will combine with saturated fatty acids and deposit in the human body, leading to arteriosclerosis.
Therefore, linoleic acid has the reputation of "vascular scavenger".
3. Black bean ash
Ash is one of the six nutrients in food, and all kinds of inorganic salts needed by human body come from ash of food. Therefore, the content of ash can reflect the nutritional value of food from one aspect.
The composition and content of ash in different foods are very different, so ash is an indicator of the total amount of inorganic components in food.
The ash content in black beans is 4.47%, which is obviously higher than other beans.
Further analysis of the ash composition of black beans showed that zinc, copper, magnesium, molybdenum, selenium, phosphorus and other minerals and trace elements were relatively high.
4, vitamins
It is estimated that everyone can talk about the importance of vitamins to human health, and you can literally guess the general meaning of the word, vitamins-the elements that sustain life.
Black beans are rich in vitamins, especially vitamin E, which is as high as 17.36 micrograms per 100 grams of black beans.
Vitamin E is a fat-soluble vitamin and one of the most important antioxidants, which plays an important role in antioxidation and protecting cells from free radicals.
5, isoflavones
Isoflavone is a kind of flavonoids, which mainly exists in leguminous plants, so it is often called soybean isoflavone. Isoflavones are also called "phytoestrogens" because they are extracted from plants and are similar in structure to female estrogens.
Previous studies have confirmed that soybean is extremely rich in isoflavones, and experiments have found that the isoflavone content of black beans is more than that of soybeans.
6. Saponin
Saponin is a complex compound existing in plant cells and an active ingredient with important medicinal value.
Black soybean saponin has protective effect on DNA damage of genetic material.
Saponins also have a good effect of scavenging active oxygen. Its mechanism may be that saponins prevent the chain reaction of free radicals, inhibit the peroxidation of polyunsaturated fatty acids on biofilm, remove lipid peroxide products, stabilize cell membrane, inhibit the abnormal increase of calcium ion level in cell membrane system, and finally protect the integrity of biofilm and subcellular structure.
Health care function of black beans
1, lowering cholesterol.
In terms of nutrition, many studies today are not only related to isoflavones, but also to their particularly rich lecithin content.
Both of them also have anti-arteriosclerosis and cholesterol-lowering effects.
It should be that the lecithin content in beans is high.
Another problem with egg yolk is that soybean is the cheapest source if it is extracted from modern science.
2, kidney.
From the perspective of traditional Chinese medicine, what did our ancients actually know about black beans a long time ago? He thinks black beans are kidney-nourishing.
This kind of black is the true color of our kidneys, and this eye-catching is actually through tonifying the kidney.
We can supplement our liver blood indirectly through the filling of the kidney meridian, so that our eyes will become bright and beautiful after the liver blood is nourished.
Traditional Chinese medicine believes that the luster and moistening of human skin depends on the nourishment of our kidney qi, the filling and warmth of kidney qi and the moistening of kidney meridians.
We often eat black beans, which not only tonify kidney qi, but also tonify kidney yin.
This will delay the aging of our skin and reduce the appearance of wrinkles.
At the same time, eating black beans often can reduce chloasma and senile plaque caused by pigmentation, so black beans are good skin beauty products.
3, benefit the spleen.
Black beans belong to the kidney meridian, because they are sweet and enter the spleen meridian.
Entering the spleen meridian, he not only has the function of tonifying kidney, but also has the function of strengthening spleen.
Chinese medicine, if it strengthens the spleen, has the function of strengthening the spleen and benefiting qi.
Eating black beans often can improve people's qi, and black beans can also remove water.
For example, some of us have edema and swollen faces, and eating black beans for a long time can have a good diuretic effect.

The beauty effect of black beans can delay aging! Because black beans are rich in antioxidants-vitamin E, which can eliminate free radicals in the body, reduce skin wrinkles and achieve the purpose of beauty beauty.
Li Shizhen once said two things in Compendium of Materia Medica.
One is that he told a story about a man named Li Shouyu. He has a habit. He just gets up every morning and swallows 27 black beans. As a result, he is neither old nor old.
There is also a man named Zeng Quan. His habit is to eat 30 black beans after meals every day. As a result, when people get old, they think they are still like young people, so we say that black beans have the function of prolonging life.
Rehmannia glutinosa and black beans each have a handful of boiling water and rock sugar, which has the effect of nourishing blood and beautifying face.
Su Dongpo, a writer in the Song Dynasty, once recorded one thing in his book, that is to say, the scene of young girls fighting for black beans for beauty inside and outside the Beijing Palace was very vivid.
So Chinese medicine has long said that black beans are beautiful.
The nutritional value of black beans is 1, beauty beauty.
Black bean sprouts are rich in amino acids, carotene, vitamins B 1, B2, B 12 and other nutrients needed by human body. Black bean sprouts are also rich in soybean isoflavones, which have antioxidant and free radical inhibiting effects. Soybean isoflavones have estrogen-like effects, which can regulate the level of estrogen secretion in two directions, thus achieving the effect of beauty beauty.
2. Reduce blood fat.
Sterols from beans can inhibit the production of endogenous cholesterol and the absorption of exogenous cholesterol, increase the excretion of cholesterol, and thus reduce blood lipids.
3. lose weight.
When black beans germinate into black bean sprouts, the contents of carbohydrates and fats are greatly reduced, while the contents of vitamins and cellulose are greatly increased. Black bean sprouts can be regarded as a 4-star diet food, with low unit calories, and the fat content per 100g is less than1g.
Extended data:
Black beans have unique substances that ordinary foods do not have, and it is these unique substances that enhance the nutritional and health care status of black beans in beans.
Scientific research shows that black beans have the characteristics of high protein and low calorie, and their protein content is as high as 36%-40%, which is twice that of meat, three times that of eggs and 12 times that of milk.
It is rich in 18 amino acids, especially 8 amino acids necessary for human body, which is higher than the high protein standard stipulated by FDA.
Black beans also contain 19 kinds of oils, with unsaturated acid content of 80% and absorption rate of over 95%, which can not only meet the human body's demand for fat, but also reduce blood cholesterol.
Black beans basically contain no cholesterol, only phytosterol, which is not absorbed by human body, but can inhibit the absorption of cholesterol and reduce the cholesterol content in blood.
