Yam, I believe that everyone usually eats a lot of yam. It is a food with the same origin of medicine and food. In the “Shen Nong’s Herbal Classic”, yam is listed as the top quality tonic, With the reputation of “little ginseng”,has the effect of invigorating the spleen, nourishing the lung, nourishing the qi and strengthening the kidney.

Yam is indeed a high-quality and inexpensive “supplement” with rich nutrition, including a large amount of vitamins, minerals, amylase, polyphenol oxidase and other healthy ingredients .
At the same time, it also has medicinal value, because it contains yam polysaccharide, diosgenin and other ingredients.
As for yam, there is a saying that “the shape complements the shape”, mainly because of the diosgenin in it. If ingested, this substance can produce some stimulant effects.
Afterwards, some health articles began to hype that eating yam can stimulate sexual excitement, especially “iron stick yam”, which can be Complementary form, more and more exaggerated. But the efficacy of yam is limited, and everyone should look at it rationally.
As for yam to nourish the stomach, it is indeed possible.
Because the starch granules in yam are relatively small, the crude fiber content is low, easy to digest, and less irritating to the stomach , and yam can also promote the production of digestive enzymes, improve digestion speed, and is beneficial to gastrointestinal health.
In short, yam is a good thing, you can eat it properly at ordinary times, it is good for your health.
Second, eating yam is tonic, eating wrong is “gunpowder”
Although yam is good, it has certain effects, but the premise is that you have to eat it correct. Fan Zhihong, director of the Chinese Nutrition Society, said that eating yam correctly can benefit the body a lot.
1. Helps digestion
The content of amylopectin in yam starch is relatively Tall, easily digestible. Plus it also stimulates the digestive system to produce more digestive enzymes, which also helps promote digestion.
2. Improve immunity
Some studies have found that yam extract can improve the proliferation ability of immune cells, thereby improving the body’s resistance to digestive tract infectious diseases.
3. Protect the gastrointestinal tract
The texture of yam is relatively fine and coarse. The fiber content is also relatively small, which is less irritating to the gastrointestinal tract. Its unique mucin can also moisturize the gastric mucosa, protect the stomach wall and protect the gastrointestinal tract.
It can be seen that there are still many benefits of yam, and it can be eaten in moderation.
But it should be noted that not everyone is suitable for eating yam, such as:< /span>
Constipation: Chinese yam has the effect of regulating the spleen and stomach and stopping diarrhea, but it will aggravate the symptoms of constipation after eating;< /span>
diabetic patients: Because yam contains high starch content, too much intake can easily lead to blood sugar fluctuations;
renal insufficiency: Chinese yam contains a lot of potassium, too much intake can increase the burden on the kidneys ,Worse.
So, before eating yam, you must know whether it is suitable for you to eat, so as to avoid harming yourself by eating the wrong thing.
