What are the benefits of eating potatoes to the human body?

Potatoes and other potato foods are rich in dietary fiber, which have been regarded as healthy foods since ancient times, and have recently attracted people's attention as anti-cancer foods.

In recent years, scientific research has found that potatoes contain a variety of ingredients beneficial to human body, and their edible value is getting higher and higher, which denies the traditional concept that potatoes are only high-starch foods and cannot be eaten more.

Folk therapy believes that potatoes can protect and strengthen mucous membranes. It is said that drinking raw potato juice or eating burnt potatoes is very effective in treating gastric ulcer and duodenal ulcer.

(1) Why can potatoes fight cancer?

This is because potatoes contain ganglioside, β-carotene, vitamin C, vitamin E, dietary fiber, phenols, phytic acid, chlorogenic acid and other anticancer components.

① Anti-cancer effect of ganglioside

Potato has a good anticancer effect, which has been confirmed by many experiments. Professor Doka's research report in Japan is one of them.

Which component of potato can prevent the proliferation of cancer cells? Professor Dogan believes that ganglioside in potato juice has anti-cancer effect.

② The anticancer effect of phytic acid.

Potatoes contain phytic acid, an important anticancer component.

Generally speaking, iron, copper and other metal components combine with other substances in the body to achieve a stable state after ingestion, which is harmless to the body. However, if there is no binding target, it will become a free radical (a component that forcibly takes electrons from other substances), leading to chain oxidation of cells, which may lead to the formation of cancer.

Phytic acid can inhibit the transformation of metal components into free radicals.

③ The anticancer effect of chlorogenic acid.

Potatoes are rich in chlorogenic acid (a polyphenol), which can prevent cell mutation, especially potato skin.

Cancer is caused by the sudden mutation of genetic factors in cells and the action of carcinogens. Therefore, it is of great significance to prevent mutation in the first stage.

Experiments in the United States also prove that potato skin has antioxidant effect.

(2) Effective ways to eat potatoes

Potato is a low-energy food. It takes 100g to generate 35 1KJ of heat (equivalent to 50g of rice). Like sweet potatoes, vitamin C is not easy to be destroyed during heating and cooking. It can be boiled, fried, and soup, and can be used in various dishes.

Among them, meat, carrots and onions can be stewed with potatoes, because carrots and onions are rich in antioxidant components, which can further enhance the antioxidant effect. Fried potatoes are not suitable for eating, because frying will increase the fat content and easily cause obesity, which should be avoided as much as possible.

In addition, if sweet potatoes and potatoes are eaten with skin, they can improve the anti-cancer effect, absorb vitamin C more effectively and experience the original taste of potatoes.

(3) Suggestions on potato consumption

Because potatoes are a kind of storage-resistant vegetables, they are easy to eat frequently. In view of its high starch content, don't eat too much every meal, so as not to affect the normal digestive function.
