Sweet potato, also known as sweet potato, sweet potato, sweet potato, sweet potato, sweet potato and so on. It is an annual plant of convolvulaceae, and it is a kind of health food with both medicine and food. Sweet potato contains dietary fiber, carotene, vitamins A, B, C, E, and potassium, iron, copper, selenium, calcium and other trace elements 10. With high nutritional value, it is called the most balanced healthy food by nutritionists. Many girls who love beauty think sweet potatoes are sweet, and they are afraid that if they eat too much, they will get fat. Sweet potato not only won't get fat, but also can lose weight, keep fit, prevent sub-health, relieve constipation and detoxify. Every100g of fresh sweet potato contains only 0.2g of fat, which generates 99 kilocalories of heat energy, which is about 1/3 of that of rice. It is a good food with low fat and low heat energy, and it can effectively prevent sugar from transforming into fat, which is conducive to weight loss and bodybuilding. Sweet potato contains a lot of dietary fiber, which cannot be digested and absorbed in the intestine. It can stimulate intestinal tract, enhance peristalsis, relieve constipation and detoxify, especially for senile constipation.

In particular, sweet potato is an alkaline food, and like many fruits and vegetables, it is the most rare. General foods are acidic, such as grain, chicken, duck, fish and so on. 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 potatoes at the same time can reduce blood cholesterol and prevent "modern diseases" such as sub-health, cardiovascular and cerebrovascular diseases.

Eating sweet potatoes correctly is also particular. First, we must pay attention to steaming thoroughly. Because the cell membrane of starch in sweet potato is not destroyed by high temperature, it is difficult to digest. Moreover, the gasification enzyme in sweet potato will not be destroyed by high temperature, which will cause discomfort after eating. Second, it should be noted that excessive or unreasonable consumption of sweet potato will cause abdominal distension, heartburn, pantothenic acid, stomach pain and so on. Therefore, it is not advisable to eat too much. People diagnosed by TCM as dampness blocking the spleen and stomach and qi stagnation should eat carefully.

The disadvantage of sweet potato is the lack of protein and lipids, but today people are rich and no longer take sweet potato as their staple food, and their lack of nutrition can be supplemented by other diets. For example, eat milk and sweet potatoes at the same time, because milk is rich in protein and fat.

Enough is enough in everything. Eating too much is definitely not good.

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 and burp.

Secondly, sweet potato has a high sugar content. Eating too much will produce a lot of stomach acid, which makes people feel heartbroken.

The stomach is stimulated by acid and its contraction is strengthened. At this point, the myocardium at the junction of stomach and esophagus is relaxed, and the acid in the stomach flows back to the feeding tube, so people spit acid water.

At the same time, too much sugar can't be absorbed by the body for a while, and the rest will ferment in the intestines, which will also make the stomach uncomfortable.

Sure, it's no problem to eat two at a time.
