Sweet potatoes contain dietary fiber, carotene, vitamins A, B, C, E, and more than 10 trace elements such as potassium, iron, copper, selenium, and calcium. They have high nutritional value and are called the most balanced nutritional health food by nutritionists. Many girls who love beauty feel that sweet potatoes are very sweet and are afraid that they will gain weight if they eat too much.

Eating sweet potatoes will not only not gain weight, but can lose weight, build body, prevent sub-health, and relieve constipation and detoxification.

At the same time, it can effectively prevent sugar from turning into fat, which is conducive to weight loss and bodybuilding. Sweet potatoes contain a large amount of dietary fiber, which cannot be digested and absorbed in the intestine.

Sweet potatoes are alkaline foods. Like many fruits and green vegetables, they are the most rare. General foods are acidic, such as grains, chickens, ducks, fish, etc., while the pH value of the human body is 7. 34, so eating sweet potatoes is beneficial to the body's acid-base balance. Eating sweet potatoes at the same time can lower blood cholesterol and prevent "modern diseases" such as sub-health and cardiovascular and cerebrovascular diseases.

Sweet potatoes are not only nutritious, but also rank first among anti-cancer foods. There are many introductions to this literature. The "ranking" of 20 anti-cancer vegetables released by the National Cancer Research Center of Japan is: sweet potatoes, asparagus, broccoli, celery, sweet peppers, carrots, golden flowers, amaranth, shepherd's purse, kohllum, mustard greens, tomatoes, green onions, garlic, cucumber, Chinese cabbage, etc., among which sweet potatoes rank first.

Moreover, Japanese doctors found through a dietary survey of 260,000 people that the cancer suppression rate of cooked sweet potatoes is higher than that of raw sweet potatoes. A survey of the hometown of centenarians in western Guangxi found that the long-lived elderly people here have a common characteristic, that is, they are accustomed to eating sweet potatoes every day and even use them as a staple food.

The mechanism of sweet potatoes fighting cancer is not very clear, and there are many theories. For example, some reports say that the Philadelphia Hospital in the United States extracted an active substance-desandrosterone from sweet potatoes, which can effectively inhibit the occurrence of colon and breast cancer. Another American university study found that there is a substance called dehydroepiandrosterone in sweet potatoes, which has a certain effect on preventing and treating cancer. Sweet potatoes have a certain anti-cancer effect, but the "ability" of sweet potatoes to fight cancer cannot be exaggerated and must be treated dialectically, because its mechanism is not yet fully clear. The greatest effect of sweet potatoes should also be in weight loss, bodybuilding, prevention of sub-health, laxative detoxification and other aspects.

Regarding the anti-cancer effect, traditional Chinese medicine theory believes that it is due to its laxative and detoxification, which can reduce the accumulation of garbage and toxins in the human body. Scientific experiments have not been carried out on the mechanism and reasons of sweet potatoes 'anti-cancer. Theoretically, it is speculated that it is rich in dietary fiber, can relax the intestines, treat constipation, and is beneficial to preventing colon cancer and other cancers.

There are also special considerations when eating sweet potatoes correctly. First, we must pay attention to steaming and boiling them thoroughly. Because the cell membrane of starch in sweet potatoes is not destroyed by high temperature, it is difficult to digest. Moreover, the gasifying enzyme in sweet potatoes is not destroyed by high temperatures and will cause discomfort after eating. Second, it should be noted that when eating sweet potatoes too much or unreasonable, it will cause abdominal distension, heartburn, pantothenic acid, stomach pain, etc. Therefore, it is not advisable to eat too much. People with dampness obstructing the spleen and stomach and stagnation of qi in traditional Chinese medicine should eat with caution.

The shortcoming of sweet potatoes is their lack of protein and lipids. However, today, people are rich and no longer use sweet potatoes as a staple food. The nutrients it lacks can be completely replenished through other diets. For example, eat milk and sweet potatoes at the same time because milk is rich in protein and fat.

According to ancient documents such as "Compendium of Materia Medica" and "Compendium of Materia Medica","Compendium of Materia Medica", sweet potatoes have the effect of "replenishing deficiency, replenishing strength, strengthening spleen and stomach, and strengthening kidney yin", making people "live longer and have fewer diseases". It can also replenish the middle, balance the blood, warm the stomach, fatten the five internal organs, etc. Contemporary "Chinese Materia Medica" says: "Sweet taste, calm nature. Return to the spleen and kidney meridians." "Strengthen the middle and regulate the blood, replenish the qi and promote the body, widen the stomach, and relieve constipation. Indications for spleen deficiency edema, sore swelling, intestinal dryness and constipation." (Editor in charge: Yang Miao)
