First, compare macro nutrients. Compared with the two, potatoes have higher calories, but the protein content of potatoes is relatively high. Moreover, sweet potato has a high sugar content, so it tastes really sweet.

As far as micronutrients are concerned, both potatoes and sweet potatoes can provide important trace elements for the human body. It should be noted that potatoes and sweet potatoes are staple foods. Eating too much will increase calorie intake, which will make you fat in the long run. No food is born with the effect of "losing weight" or "gaining weight". Losing weight or gaining weight depends on "how much to eat" and "how to eat". Eat one medium-sized potato or sweet potato at a time.

Don't eat staple food at the same time, and avoid the combination of baked sweet potato+noodles or shredded sweet potato+rice.

Potatoes contain a high amount of potassium in vegetables, and at the same time, compared with other staple foods (wheat, corn, etc. ), the phytic acid content in potatoes is less, which will not affect the absorption of iron and zinc (details can be found through the hyperlink on how to eat iron supplement).

Sweet potato is a big family of vitamin A. When it comes to vitamin A, we always think of carrots. In fact, the vitamin A content of 1 medium-sized sweet potato is equivalent to two carrots, which can meet the recommended amount of vitamin A for an adult all day. At the same time, there is quite a lot of vitamin C in sweet potato.
