Black beans are the black seeds of the legume soybean (scientific name: Glycinemax(L.) merr). Black beans are also known as olive beans, black soybeans and so on. Black beans have high protein, low calorie properties, black skin, yellow or green inside.
Black beans like warmth, high temperature resistance, fertility temperature of 18 to 30 degrees, sowing method of propagation to large and full particles, color black shiny is better.
According to a study by Chinese scientists, black bean skin extract can improve the body's absorption of iron, and eating black beans with skin can improve symptoms of anemia.
Modern medical research has proved that the high content of unsaturated fatty acids in black beans has the effect of lowering cholesterol, softening blood vessels, and preventing arteriosclerosis and blockage. Japanese scientists have found that allowing patients with high blood pressure to drink black bean juice can significantly reduce blood pressure, and it has a certain effect on the treatment of diabetes, gray hair and allergies.
In short, black beans are of great benefit to senile diseases such as high blood pressure, heart disease, liver, and arteriosclerosis.
<h1>Black bean nutrients:</h1>
Black beans are rich in nutrients, containing proteins, fats, vitamins, trace elements and other nutrients, and at the same time have a variety of biologically active substances, such as black bean pigments, black bean polysaccharides and isoflavones.
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 soybeans, ranking first among all kinds of beans, so it has also won the reputation of "the king of beans". Compared with protein-rich meats, black beans are not only not inferior, but more superior, their protein content is equivalent to 2 times that of meat (pork, chicken), 3 times that of eggs, and 12 times that of milk, so it is also known as "plant protein meat".
2. Fatty acids
Studies have found that each 100 grams of black beans contains as much as 12 grams of crude fat. The test found that it contained at least 19 kinds of fatty acids, and the content of unsaturated fatty acids was as high as 80%, of which the linoleic acid content accounted for about 55.08%. As a kind of unsaturated fatty acid, linoleic acid is a very important essential fatty acid in the human body, which has a vital regulatory effect on cholesterol metabolism, and can only be transported in the body when cholesterol is combined with linoleic acid for normal metabolism. When linoleic acid is deficient, cholesterol will bind to saturated fatty acids and deposit them in the human body, leading to the occurrence of arteriosclerosis. Therefore, linoleic acid has the reputation of "vascular scavenger".
3, black bean ash
Ash is one of the six major nutrients of food, and all kinds of inorganic salts needed by the human body come from the ash content of food, so the amount of ash content can reflect the nutritional value of food from one aspect. The ash composition and content of different foods vary greatly, 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 significantly higher than that of other beans. Further analysis of the composition of black bean ash, can find a variety of minerals and trace elements, such as zinc, copper, magnesium, molybdenum, selenium, phosphorus, etc., and the content is relatively high.
4. Vitamins
The importance of vitamins to human health, it is estimated that everyone can say something, just from the literal can guess the approximate meaning of this word, vitamins - life-sustaining elements. Black beans are rich in a variety of vitamins, especially vitamin E containing up to 17.36 micrograms per 100 grams of black beans. Vitamin E is a fat-soluble vitamin that is one of the most important antioxidants and plays an important antioxidant role in protecting the body's cells from free radical poisoning.
5. Isoflavones
Isoflavones are one of the flavonoids, mainly present in legumes, so they are often called soybean isoflavones, because they are extracted from plants, similar to the structure of female estrogen, so isoflavones are also known as "phytoestrogens". Studies have long confirmed that the isoflavone content of soybeans is extremely rich, and some experiments have found that the isoflavone content of black beans is more than that of soybeans.
6. Saponins
Saponin is a compound with complex structure in plant cells, and it is also a plant active ingredient with important medicinal value. Black bean saponins have a protective effect on DNA damage to the genetic material. In terms of scavenging reactive oxygen species, saponins also have a good effect, the mechanism of which may be that saponins terminate the chain reaction of free radicals, inhibit the peroxidation of more unsaturated fatty acids on the biofilm, remove lipid peroxidation products, stabilize the cell membrane, inhibit the abnormal increase in the level of calcium ions in the cell membrane system, and finally achieve the effect of protecting the integrity of the biofilm and subcellular structure.
7. Polysaccharides
Black bean polysaccharides are one of the heroes who scavenge free radicals from the human body. Studies have found that black bean polysaccharides are non-reducing, non-starchy polysaccharides, which have a significant effect on scavenging free radicals in the human body, especially the scavenging effect on superoxide anion free radicals is very powerful. In addition, studies have found that the polysaccharide components in black beans can also promote the growth of bone marrow tissue, which has the effect of stimulating the regeneration of hematopoietic function.
8. Black bean pigment
Black bean pigment is one of the important biologically active substances of black bean, and the natural pigment prepared with black bean skin as raw material is called "black bean red pigment", referred to as "black bean red". Black bean red pigment can reduce the content of malondialdehyde (MDA), the final product of lipid peroxidation reaction, while increasing the content of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px), which means that black bean red pigment has obvious antioxidant effects.
<h1>Black beans: Ten benefits of the legume soybean:</h1>
1. Improve immunity
Black beans contain plant-based protein and are known as "plant meat". If the human body lacks protein, it will have symptoms of decreased immunity and easy fatigue. Eating black beans to supplement protein can avoid the problem of elevated cholesterol.
2, let people think smart
Black beans are rich in soy lecithin, which is one of the important components of the brain. Eating more black beans can help prevent Alzheimer's disease. In addition, the sterols in black bean lecithin can increase nerve function and vitality. At the same time, lecithin can emulsify and decompose oils and fats to accelerate metabolism. Promote fat degradation, protect the liver, prevent the occurrence of fatty liver and other diseases. And improve brain vitality, eliminate brain fatigue, improve learning and work efficiency.
3. Strong organs
Black bean lecithin can promote the absorption of fat-soluble vitamins and strengthen the body's tissues and organs. In addition, it can lower cholesterol, improve lipid metabolism, prevent and treat coronary artery sclerosis.
4. Improve efficiency
The protein in black beans can increase the excitatory and inhibitory functions of the cerebral cortex, improve learning and work efficiency, and also help alleviate depressed and depressed emotions.
5. Beauty and skin care
Black beans are rich in soy isoflavones, phytoestrogens that improve skin aging and also alleviate menopausal syndrome. In addition, Japanese researchers have found that the linoleic acid contained in black beans can effectively block the synthesis of melanin in skin cells.
6. Prevent cancer
Black beans contain protease inhibitors, and researchers at New York University in the United States have found that it can inhibit a variety of cancers, and the inhibitory effect on breast cancer is the most obvious.
7. Prevent oxidation
The soy saponins in black beans can scavenge free radicals in the body and have antioxidant effects. It can also inhibit the growth of tumor cells and enhance the body's immune function.
8. Reduce blood lipids
The plant cholesterol in black beans has the effect of lowering blood cholesterol. It competes with cholesterol in the intestines and reduces cholesterol absorption. While reducing the "bad cholesterol" in patients with hyperlipidemia, it does not affect the "good cholesterol" in the blood, and has a good lipid-lowering effect.
9. Prevention of deafness
Iron supplementation can dilate microvessels, soften red blood cells, ensure blood supply in the ear, and effectively prevent hearing loss. The content of iron and zinc in black beans is much higher than that of other foods, which has a certain effect on preventing deafness in the elderly.
10. Auxiliary pressure relief
American scientists have found that patients with high blood pressure consume too much sodium and too little potassium in their diets. The intake of high potassium foods can promote the excretion of excessive sodium in the body, which has the effect of assisting in lowering blood pressure. Black beans are rich in potassium, with potassium content of up to 1503 mg per 100 grams of black beans. Patients with high blood pressure often eat black beans, which is very helpful for timely supplementation of potassium in the body.
