Black beans belong to soybean food, and their nutritional value is higher than that of familiar soybeans. The nutritional value of black beans is mainly reflected in the nutritional components contained in black beans. The health-preserving function of black beans can be specifically divided into the following categories:
1 Supplementing protein and protein is self-evident. If the human body lacks protein, its growth and development will be affected, and its immunity will also decline. The content of protein in human body is second only to that of water, but although the material conditions have improved now, many people lack protein.
The staple food is the main food source in protein, but the protein contained in the staple food is semi-complete protein, and the protein needed by the human body also needs one-third to one-half of the high-quality protein. Although meat food also contains protein, some people don't like meat. At this time, you can choose soybean food, and black beans are a good choice.
The content of protein in black beans is relatively high, about 35%, which is higher than that of protein in meat. As for steamed bread and rice, they are no match for black beans. When making steamed bread, if you add some black bean powder or soybean milk and flour made of black beans, the steamed bread is not only delicious, but also the content of protein will increase.
2 There is a problem with the stability of blood lipids, and the body will gradually have more problems. Hyperlipidemia is one of the killers of coronary heart disease and one of the pathogenic factors of cerebrovascular disease. Many problems caused by hyperlipidemia can not be ignored. There are many reasons for hyperlipidemia. Friends who love meat may have hyperlipidemia.
Cholesterol only exists in animal foods, and plant foods do not contain cholesterol. Soybeans contain no cholesterol, and black beans also contain no cholesterol. Moreover, black beans also contain a substance called phytosterol, which plays an important role in stabilizing blood lipids. Phytosterol can compete with cholesterol in intestine, reduce cholesterol absorption, effectively reduce the "bad" cholesterol content in blood of hyperlipidemia patients, without affecting the "good" cholesterol in blood, and has a good lipid-lowering effect on hyperlipidemia patients.
Black beans are the best among soybean foods. If you eat soybeans regularly, you don't have to worry about cholesterol, and the food source of phytosterols is also guaranteed. This is also good news for patients with hyperlipidemia.
3 Supplementing soybean isoflavones Soybean isoflavones have the reputation of phytoestrogens, and the content of soybean isoflavones in black beans is not low. In the book "Reference Intake of Dietary Nutrients for China Residents 20 13", it is proposed that premenopausal women should consume 2 1 mg of soybean isoflavones every day, and postmenopausal women should consume 55 mg of soybean isoflavones every day to minimize the risk of female breast cancer.
Some people may worry that children who eat black beans will have precocious puberty and dare not let them eat black beans. In fact, although black beans contain soy isoflavones, daily intake will not lead to precocious puberty in children. Children's daily intake of soybean isoflavones should be controlled within 50 mg. As long as you don't eat black beans, you don't have to worry about precocious puberty.
As for the problem that men are black beans, let alone soybean isoflavones, there is no tolerable maximum intake of soybean isoflavones at present. And men often eat black beans, which is also good for their health.
Dietary fiber supplement Dietary fiber is one of the seven nutrients needed by human body, and it has many benefits to human health. If you want to lose weight, you can't live without dietary fiber. Dietary fiber can increase satiety, reduce food intake, control weight and lose weight. At the same time, dietary fiber can absorb water and expand, promote gastrointestinal peristalsis, reduce the retention time of feces in the intestine, promote fecal excretion, and prevent constipation and colon cancer.
Dietary fiber is indispensable for diabetics. Dietary fiber can form a diaphragm in the intestine, block the absorption of sugar and fat in the intestine, delay the increase of blood sugar after meals, help the human body stabilize blood sugar, and play an important role in controlling blood sugar. The skin of black beans contains dietary fiber. Black beans can be made into soybean milk or ground into black bean powder to retain dietary fiber.
The nutritional value of black beans is not only the above four aspects. To obtain the health care function of black beans, it is a good choice to drink a cup of black bean milk every day!
