Bean varieties are extremely rich, and they can be categorized into many types by color, such as red beans, mung beans, soybeans, black beans, and more. Today, the editor will introduce you to the health benefits of black beans.
Health Benefits of Black Beans
1. Preventing Arteriosclerosis
Every 100 grams of black beans can provide 371 kilocalories of energy, with protein accounting for 36-40%, which is high-quality plant protein that is easily digested and absorbed by the human body. Fat accounts for 15%, mainly consisting of unsaturated fatty acids (oleic acid, linolenic acid), which can promote the metabolism of cholesterol in the blood. In addition, the plant sterols contained in black beans can compete for absorption with sterols from other foods, accelerating the excretion of sterols in the feces and preventing excessive cholesterol from accumulating in the body. In animal studies, rabbits with hypercholesterolemia that consumed black beans showed a greater improvement in the degree of vascular embolism compared to those that consumed soybeans. Recent preliminary research has confirmed that roasted black beans can reduce the concentration of triglycerides in human plasma by 23%.
2. Anti-Aging
Black beans are rich in vitamin E, anthocyanins, and isoflavones. These components have antioxidant capabilities. Vitamin E can scavenge free radicals, becoming the outermost protective layer against oxidation in the body. The red anthocyanins released from the black bean seed coat can eliminate free radicals in the body and exhibit better antioxidant activity in an acidic environment (when gastric acid is secreted), thereby enhancing vitality. Isoflavones have been proven to have various physiological functions, such as preventing osteoporosis, preventing cancer, and providing antioxidant effects. Therefore, black beans can be used in health-preserving diets for specific diseases. According to current human studies, consuming 40 grams of roasted black beans daily can delay the oxidation of low-density lipoprotein (bad cholesterol).
3. Preventing Brain Aging
The unsaturated fatty acids in black beans can be converted into lecithin in the human body, which is the main component of brain nerves. Among the minerals contained in black beans, calcium and phosphorus both have the effect of preventing brain aging and sluggishness, and are beneficial for brain health and intelligence.
4. Beauty and Hair Care
Black beans are also rich in B vitamins and vitamin E, which are nutritional components needed for skin care and beauty. In particular, their high content of pantothenic acid also helps to keep hair from turning white.
5. Preventing Constipation
Black beans contain 5% crude fiber and oligosaccharides. They not only help intestinal peristalsis, allowing gas and toxins to be smoothly expelled from the body and improving constipation, but the oligosaccharides also promote the proliferation of bifidobacteria, thereby improving the intestinal flora environment and having a regulatory effect on the intestines.
In fact, eating black beans regularly can effectively help people maintain their health. These five major benefits—preventing constipation, enhancing beauty and hair care, preventing brain aging, preventing arteriosclerosis, and anti-aging—are the protective effects that regular consumption of black beans has on the body. Therefore, for those who want to strengthen their bodies through health-preserving methods, they should eat black beans regularly as a food.
