The main component of bean jelly is starch, which belongs to polysaccharide. Starch can be decomposed in the body and converted into monosaccharide. If energy cannot be released effectively, it is likely to be converted into fat and gathered in the body, which is the obesity that most people are worried about. Moreover, when eating bean jelly again, the amount of oil used for seasoning is relatively large, which is also easy to lead to obesity.
