Overview of the health benefits of yam

Yam is a kind of food that has the same origin as medicine and food. It is rich in active ingredients such as mucin, amylase, and polyphenol oxidase. It has the effects of strengthening the spleen and stomach, nourishing the kidneys and replenishing essence, moistening the lungs and relieving coughs. Modern research has also found that it helps regulate blood sugar and enhance immunity. This article will analyze the health value of yam from the perspective of traditional Chinese medicine theory and modern science, and list related products for reference.

1. Strengthen the spleen and stomach, aid digestion and absorption

The mucin in yam can protect the gastric mucosa, and amylase and polyphenol oxidase can promote digestion. "Compendium of Materia Medica" records that it "reinforces kidney qi and strengthens the spleen and stomach", and is especially suitable for people with weak spleen and stomach. Clinical observation shows that long-term consumption of yam can improve symptoms such as loss of appetite and abdominal distension. For example, Tongrentang's "Yam Poria Granules" are formulated with this formula to help regulate gastrointestinal function.

2. Tonify the kidneys and strengthen essence, improve sub-health

Traditional Chinese medicine believes that yam enters the kidney meridian and has a certain effect on alleviating the soreness and weakness of the waist and knees and frequent nocturia caused by kidney deficiency. Its rich saponins and amino acids can regulate endocrine. Zhang Jingyue, a physician in the Ming Dynasty, recommended yam combined with wolfberry to nourish the kidneys. Modern products such as "Jiuzhitang Liuwei Dihuang Pills" contain yam ingredients and are targeted at people with kidney yin deficiency.

3. Assist in sugar control and metabolism regulation

The dietary fiber and chromium in yams help delay sugar absorption and are beneficial for diabetics. A 2020 study in "Chinese Food and Nutrition" pointed out that yam polysaccharides can improve insulin sensitivity. Some brands such as "Jiangzhong Brand Yam and Barley Paste" are specially designed for blood sugar management, but please note that they cannot replace drug treatment.
