When eaten, agar will not be absorbed by human body, and it has the function of moistening intestines and relaxing bowels. It is suitable for diabetic patients and can also be used to lose weight. It is generally extracted from marine plant watercress, so it has no side effects. But it is often used as a culture medium in the laboratory, but it is actually one thing. I feel that the agar used in our laboratory is the same as that used in the kitchen. If you eat, try to buy that kind of food packaging. Don't worry. Also, agar is also called bean jelly.
