Compare the two food is nutritious, as long as you compare the nutritional value and nutrient types and content of the two, it is easy to see. The following comparison:

A: black beans:

Black beans are comprehensive, rich in protein, vitamins, minerals, blood, water, wind, the effect of detoxification.

II: Soybean:

Soybeans are rich in protein and contain a variety of essential amino acids, which can improve the body's immunity;

The lecithin in soybeans can get rid of cholesterol attached to the walls of the blood vessels, preventing hardening of the blood vessels, preventing cardiovascular disease and protecting the heart.

When comparing the two, soybeans have a wider variety of nutrients than black beans, and the carotenoid content of soybeans (220 mcg) is much higher than that of black beans (50 mcg), and soybeans also have higher levels of vitamin A than black beans.

Finally, while the price of a food may be an indication of its nutritional value, it is not an absolute indicator. The amount of food, the degree of scarcity, sales, regional eating habits have a relationship, for example, South and North tofu in the nutritional value of almost no difference, just slightly different taste, but, in the South, certainly eat South tofu, and in the North, but also eat North tofu, which is caused by eating habits. And definitely not the south of the tofu is definitely better than the north of the tofu, and vice versa!
