1. Prevention of arteriosclerosis

Black beans can provide 37 1 calorie per100g, and protein accounts for 36-40%. It is a kind of high-quality plant protein, which is easy to be digested and absorbed by human body. In addition, phytosterols contained in black beans can compete with sterols in other foods for absorption, thus accelerating the excretion of sterols in feces and avoiding excessive accumulation of cholesterol in the body.

2. Anti-aging

Black beans are rich in vitamin E, anthocyanins and isoflavones, and have antioxidant capacity. Vitamin e can capture free radicals and become a protective layer to prevent oxidation in vivo and in vitro. Therefore, black beans can be used in a healthy diet for specific diseases. According to the current human research, taking 40 grams of roasted black beans every day can delay the oxidation of low-density lipoprotein (bad cholesterol).

Prevention of constipation

Black beans contain 5% crude fiber and oligosaccharides, which not only helps intestinal peristalsis, but also eliminates flatulence and toxins in the body and improves constipation.

Taboo of black beans:

First, people with cold constitution (such as cold limbs, cold pain in waist and legs, diarrhea and loose stool). ), eating black beans will aggravate symptoms and even cause other diseases.

Second, people who are taking various drugs. The detoxification of black beans comes from the combination of black bean protein and other components with organophosphorus and heavy metals to form precipitation. However, these detoxification components will also react with the related components of drugs, thus reducing the efficacy.

Third, the elderly, children (children's food) and people with weak constitution. Because the content of protein in black beans is more than that in chicken, macromolecular protein (protein food) needs to be converted into small peptides and amino acids (amino acid food) under the action of enzymes before it can be absorbed by human body.
