Why don't young people like to eat fat?

Fat meat contains a lot of fat, and there is no special enzyme for digesting fat in saliva and gastric juice. Only the pancreas can secrete, and bile needs to be released to soften the fat, so that it can be digested.

Some people are not used to eating fat, so this function of his pancreas is underdeveloped. When he eats fat, because there is no enzyme, a large amount of fat accumulates in the intestine, blocking the digestive tract, causing feedback from the digestive tract nerves and nausea.
