1. Do not consume in excess.
Everyone understands the principle that all things should be consumed in moderation, and even the best foods should not be eaten in large quantities. About ten beans or a cup of soy milk per day is sufficient.
2. Do not eat raw.
Substances in black beans that are harmful to the body, such as trypsin inhibitors, lectins, and goitrogens, can only be destroyed after being cooked. Therefore, do not eat raw black beans.
3. Do not consume on an empty stomach.
Black beans contain a large amount of fiber, which is difficult to digest. Eating them on an empty stomach can irritate the stomach and intestines.
