The weather changes cold. Many people will come to roast or steamed sweet potatoes with hot trench. Some people are used to peel them before eating them, while some will be eaten together. What benefits or effects does sweet potato skin have on human body? The Japanese media website "Hint-Pot" asked the nutritionist and the museum Ayumi Wakan to tell everyone the nutritional value of sweet potato peels and the things to pay attention to when eating them.
In addition to being rich in dietary fiber, sweet potato peels also include "green acid" and "anthocyanins", which have antioxidant effects and can help humans adjust their physiological functions.
Among them, "green acid" is a natural polyphenol compound, which is found in large quantities in coffee beans and is also a common ingredient in fruits and vegetables. Green acid, as an antioxidant, can inhibit the rise of blood sugar after meals, promote fat burning, and become a health care product in the hearts of many health care workers.
Everyone is familiar with the effects of anthocyanins. In addition to protecting the eyes, they also have anti-inflammatory effects. People who want to supplement anthocyanins can choose more red sweet potatoes and purple sweet potatoes. In addition, blueberries, beets, tomatoes and other fruits and vegetables also contain anthocyanins.
Nutritionists also compare the differences in nutritional ingredients of sweet potatoes with peeled skin and no peeled skin according to the Japanese food standard ingredient list.

You can find that sweet potato peels do not have too much heat and carbohydrate, but they contain a lot of dietary fiber, which is good for health when consumed in a suitable amount. However, too much dietary fiber will cause digestive difficulties. It is best for children and people with weak stomachs to peel before eating, or not to eat too much at once.
Nutritionists also remind that most of the sweet potatoes on the market have undergone cleaning procedures, but it is best to clean them with water before cooking, and use a brush to remove dents caused by buds on the epidermis. There will be more dirt in the head. If you want to take the skin and eat them, you must carefully handle them.
