If potatoes are used as staple food, the loss of B vitamins, minerals and dietary fiber can be reduced, because potatoes are rich in dietary fiber, vitamins A, B, C and minerals, high-quality starch contains 16.5%, and there are a lot of lignin, which has high nutritional value for human body.

The loss of nutrients in the processing of potatoes will not be great. The rich starch can provide the calories needed by the human body and enhance satiety. It is known as the "second bread", and there are nutrients that the three staple foods do not have-carotene.

Disadvantages:

Potatoes are difficult to dehydrate and go bad easily if they are preserved as adults. The "deterioration" here is mildew on the one hand and germination on the other. Potato germination will produce a lot of solanine, which is a toxic substance. Therefore, if potatoes are not stored properly, it is easy to waste.

In terms of nutrients, potatoes are no problem as staple food, but the storage cost is high. Therefore, as ordinary people, if they can easily buy fresh potatoes, they can completely take them as staple food.
