When eating fruits and vegetables, even removing just a little of the skin results in a large amount of food waste. If waste disposal is bothersome, eating the skin as is can be an option. Fruits and vegetables are also rich in nutrients in their skins.

It is better to eat apples with the skin on. The dietary fiber pectin in apple skin helps promote smooth gastrointestinal movement and prevents constipation. The anthocyanins that give the skin its red color are rich in antioxidants that protect the body's health from active enzymes, and they also have the effect of strengthening lung function. Apple skin also contains ursolic acid, which helps prevent obesity and regulate blood sugar levels. There is no need to peel the skin; simply cut off the stem end before eating. This is because pesticides often remain on the stem.

It is also recommended not to discard the skin of the kabocha squash. The skin of the kabocha squash is rich in antioxidants and phenolic acids that are not found in the flesh. Phenolic acids help prevent aging and improve blood circulation, aiding in the prevention of cardiovascular diseases. You can steam the whole kabocha squash with the skin on, or collect the skin separately, dry it for about 3 to 4 days, and then brew it into tea. Not only the skin but also the seeds of the kabocha squash are highly nutritious. Pumpkin seeds contain calcium and magnesium, which are beneficial for growing children and the elderly who need to strengthen their bones, nerves, and muscles. Wash them thoroughly, dry them, peel off the skin, and then eat.

Carrots are rich in beta-carotene, which is good for eye health and vision protection. Since beta-carotene is 2.5 times more abundant in the skin than in the core of the carrot, peeling the carrot results in loss of nutrients. The beta-carotene inside carrots is a fat-soluble vitamin, so its absorption is higher when eaten with oil. Therefore, it is best to slice the carrot with the skin on and stir-fry it in oil. Polyacetylenes, an antioxidant substance, are also abundant in the skin. They help regenerate cells, slow down skin aging, and eliminate inflammation in the body.

It is also better not to peel sweet potatoes unnecessarily. The anthocyanins in the sweet potato skin help eliminate active oxygen in the body. Consuming the skin, which is rich in dietary fiber, can also promote smooth bowel movements. If you dislike eating boiled sweet potatoes with their tough skin, you can cut them into small pieces while still raw and add them to salads.

Among apples, carrots, sweet pumpkins, and sweet potatoes

The only thing I don't eat is sweet potatoes.

I ate a sweet potato with the skin on once, right when it was warm.

Except for eating, it was a bit difficult to do anything else.

Although there are nutrients beneficial to the skin,

I don't think sweet potatoes will work.
