Too much sugar can't be absorbed by the body for a while, and the rest will ferment in the intestines and make the stomach uncomfortable.

Experts say that sweet potato not only has balanced nutrition, but also has little-known functions such as preventing sub-health, losing weight, bodybuilding and anti-cancer.
Sweet potato, also known as sweet potato, sweet potato, sweet potato and sweet potato, is an annual plant of convolvulaceae. It is a kind of health food with dual functions of medicine and food. Sweet potato contains dietary fiber, carotene, vitamins A, B, C and E, and more than ten kinds of trace elements such as potassium, iron, copper, selenium and calcium. The nutritional value is very high, and it is called nutrition by nutritionists.
Professor Zhang from the Health Room of Beijing University of Chinese Medicine said that eating sweet potatoes will not only make you fat, but also help you lose weight, keep fit, prevent sub-health, and relieve constipation and detoxify. Every100g of fresh sweet potato contains only 0.2g of fat, which generates 99 kilocalories of heat energy, about one third of that of rice. It is a good low-fat and low-calorie food, at the same time, it can effectively prevent sugar from transforming into fat, which is beneficial to weight loss and fitness. Sweet potato contains a lot of dietary fiber, which cannot be digested and absorbed in the intestine. It can strengthen intestine, enhance peristalsis, relieve constipation and detoxify, especially for senile constipation.
Zhang particularly emphasized that sweet potato is an alkaline food and the most rare, just like many fruits and vegetables. Generally, food is acidic, and the PH value of human body is 7.34, so eating sweet potato is beneficial to the acid-base balance of human body. Eating sweet potato can reduce blood cholesterol and prevent "modern diseases" such as sub-health, 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 Center for Oncology of Traditional Chinese Medicine, said that sweet potato is not only nutritious, but also ranks first among anti-cancer foods. There are many introductions in this document.
The list of 20 kinds of anticancer vegetables published by National Cancer Research Center of Japan is: sweet potato, asparagus, cauliflower, cabbage, broccoli, celery, sweet pepper, carrot, cauliflower, amaranth, shepherd's purse, kohlrabi, mustard, tomato, green onion, garlic, cucumber and Chinese cabbage, among which sweet potato ranks first. Japanese doctors found that the cancer inhibition rate of cooked sweet potatoes was higher than that of raw sweet potatoes through a dietary survey of 260 thousand people.
Medical workers in China investigated the hometown of centenarians in western Guangxi, and found that all the longevity elders here have a common feature, that is, they are used to eating sweet potatoes every day, even taking sweet potatoes as their staple food.
The anticancer mechanism of sweet potato is not very clear, and opinions vary. Androsterone, an active substance extracted from sweet potato in Philadelphia Hospital, USA, can effectively inhibit the occurrence of colon cancer and breast cancer. Another American university study found that there is a substance called dehydroepiandrosterone in sweet potato, which has a definite effect on preventing and treating cancer.
Professor Zhang from the Health Room of Beijing University of Chinese Medicine believes that sweet potato has a certain anti-cancer effect, but its anti-cancer "ability" should not be exaggerated, and it should be treated dialectically, because its mechanism of action is not completely clear, and the greatest role of sweet potato should be to lose weight, keep fit, prevent sub-health, relax bowels and detoxify.
Regarding the anti-cancer effect, Chinese medicine theory holds that it can reduce the accumulation of garbage and toxins in the human body because of its catharsis and detoxification. In this regard, Professor Song Santai, director of the Cancer Center of China Academy of Military Medical Sciences and deputy director of the Cancer Committee of the whole army, also believes that the mechanism and reasons of sweet potato anti-cancer have not yet been scientifically tested. Theoretically, it is speculated that it is rich in dietary fiber, which can relieve constipation and is beneficial to prevent cancers such as colon cancer.
It is also important to eat sweet potatoes correctly. Be sure to pay attention to steaming and cooking thoroughly, because the cell membrane of starch in sweet potato is difficult to digest without being destroyed by high temperature, and the gasification enzyme in sweet potato will cause discomfort after eating; Excessive or unreasonable consumption of sweet potato can cause abdominal distension, heartburn, pantothenic acid, stomachache and so on. So you shouldn't eat too much. It should be used with caution for those diagnosed by TCM as dampness blocking the spleen and stomach, qi stagnation and blood stasis.

Question 10: How long does it take to steam sweet potatoes? Benefits and taboos of eating sweet potatoes 1. Eating sweet potatoes is taboo.
Experts pointed out that it is best to eat sweet potatoes at lunch time. This is because after we eat sweet potatoes, the calcium contained in them needs to be absorbed in the human body for 4 to 5 hours, and the afternoon sunshine can just promote the absorption of calcium. But it is best to eat sweet potatoes before lunch, so that calcium can be completely absorbed before lunch, and it will not affect the absorption of calcium in other foods at dinner.
When we process sweet potatoes, we must steam them thoroughly, which will destroy the cell membrane of starch, because it is difficult to digest. In addition, if the gasification enzyme in sweet potato is not destroyed by high temperature, we will feel uncomfortable after taking it.
1, not suitable for eating sweet potatoes with black spots. Sweet potato black spot virus with black spots is not easy to be destroyed and killed by high temperature, and it is easy to cause poisoning, resulting in a series of poisoning symptoms such as fever, nausea, vomiting, diarrhea and even death.
2. Sweet potato should not be eaten with persimmon at the same time. The main component of sweet potato is starch. It will produce a lot of fruit acid after eating. If eaten with persimmon at the same time, fruit acid can condense with persimmon tannin and pectin to form gastrolith. If you eat too much, it should be at least five hours apart. If eaten at the same time, the sugar in sweet potato will ferment in the stomach, which will increase the secretion of gastric acid and precipitate and condense with tannin and pectin in persimmon to produce lumps. When the amount is serious, it can cause gastrointestinal bleeding or gastric ulcer. If you feel upset in the stomach, you must go to the hospital for gastroscopy to see if there is stomach bleeding or gastric ulcer.
3, sweet potatoes should be appropriate.
Sweet potato contains an oxidase, which easily produces a large amount of carbon dioxide gas in human gastrointestinal tract. Eating too much sweet potato will make people bloat, burp and fart. Sweet potato has a high sugar content. Eating too much will produce a lot of stomach acid, which makes people feel heartbroken.
Gastric acid strengthens the contraction of the stomach. At this time, the myocardium at the junction of stomach and esophagus is relaxed, and the acid in the stomach flows back to the feeding tube, and people spit out acid water. Too much sugar can't be absorbed by the body for a while, and the rest will ferment in the intestines and make the stomach uncomfortable.
So the popular sweet potato regimen is not suitable for everyone. If you have diarrhea after eating it, don't force it. Eating brown rice will have the same effect.
4, baked sweet potatoes do not eat skin.
Now roasted sweet potatoes is on sale in the street, and you can smell the sweetness of sweet potatoes from a distance, so sometimes you can't resist the temptation. The burnt skin of roasted sweet potatoes is welcomed by everyone, and many people eat it together. However, experts pointed out that it is best not to eat baked sweet potatoes together with the skin. Sweet potatoes contaminated by black-spotted bacteria are not easy to distinguish after baking, so don't eat black-spotted or burnt sweet potatoes, which may cause poisoning.

When eating sweet potatoes, it is best not to drink water while eating, or add a small amount of sweet potatoes to rice porridge to relieve gastrointestinal discomfort.
Third, sweet potato is a good food for patients with skin allergies:
Take more vitamin C, because the lack of vitamin C can easily make the skin rough and dry, leading to sensitive injuries such as dermatitis and peeling. Among the fruits and vegetables rich in vitamin C, pears and kiwifruit are better. Eating more can strengthen skin tissue and help fight against external sensitivity.
