As is well known, people with poor digestion have many dietary taboos, such as chewing slowly and eating easily digestible foods. What I want to remind everyone is that for people with poor digestion, it is best to blanch vegetables before cooking.
This is because vegetables are plant-based foods. They have tough cell walls, rich in unsoftened fiber, and some vegetables contain certain anti-nutrients, such as oxalic acid, which all have a certain irritating effect on the digestive system. Therefore, even for vegetables that can be eaten raw, it is best for people with poor digestion not to eat them raw, such as lettuce and purple cabbage. After blanching, the fiber in vegetables is softened, and some anti-nutrients are also removed. In this way, the irritating effect of blanched vegetables on the digestive system will be reduced. In addition, cooking vegetables until soft and mashing them are also good ways for people with poor digestion to eat vegetables.
People with poor digestion should preferably choose cooking methods such as steaming, boiling, stewing, and braising, and should not process food with methods like frying and deep-frying.
