Sweet potato was named the best food champion

What magical powers does Little Sweet Potato have to become a "champion dish"? According to experts, sweet potatoes are not only balanced in nutrition, but also have little-known effects in preventing sub-health, weight loss, bodybuilding and anti-cancer.

Sweet potatoes, also known as sweet potatoes, white potatoes, sweet potatoes, etc., are annual plants of the Convolutes family and are a healthy food that can be used as medicine and food. 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.

Professor Zhang Hude from the Health Care Office of Beijing University of Chinese Medicine said that eating sweet potatoes will not only not gain weight, but can lose weight, build body, prevent sub-health, and relieve constipation and detoxification. Every 100 grams of fresh sweet potatoes contains only 0. 2 grams of fat produce 99 kilocalories of heat, which is about 1/3 of rice. It is a good low-fat and low-calorie food. 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. They can stimulate the intestine, enhance peristalsis, relieve constipation and detoxify, and have a good effect on elderly constipation.

Professor Zhang particularly emphasized that sweet potatoes are alkaline foods. Like many fruits and green vegetables, they are the most rare ones. 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.

Professor Lin Hongsheng, director of the Oncology Department of Guang 'anmen Hospital of China Academy of Traditional Chinese Medicine and deputy director of the National Traditional Chinese Medicine Oncology Medical Center, told reporters that 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. Medical workers in my country once conducted a survey into the hometown of centenarians in western Guangxi and found that the long-lived elderly people here have a common characteristic, which is that 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. Professor Zhang Hude from the Health Care Office of Beijing University of Chinese Medicine believes that sweet potatoes have certain anti-cancer effects, 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 placed on weight loss, bodybuilding, prevention of sub-health, laxative and detoxification.

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. In this regard, Professor Song Santai, director of the Cancer Center of the Academy of Military Medical Sciences of China and vice chairman of the Military Oncology Professional Committee, also believes that no scientific experiments have been done on the mechanism and reasons of sweet potatoes 'anti-cancer. Theoretically, it is speculated that it contains rich dietary fiber. It can relax the intestines and relieve constipation, and is beneficial to preventing cancer such as colon cancer.

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: Tian Tian)
