When it comes to yam, the first thing many people think of is medicinal stew. Nutritionist Wang Zhengwei said that yam is not only a supporting role in health-preserving dishes, but is also known as a "low-key super food" in nutrition. It has a fine texture and dense taste, and is rich in protein, polysaccharides, oligosaccharides and minerals, which can help the gastrointestinal tract and stabilize the immune system. It is an ideal choice for daily maintenance for seniors, office workers and busy modern people.

Mucus protein protects the gastrointestinal tract and reduces irritation and discomfort

One of the nutritional highlights of yam is that it is rich in "mucus protein". Wang Zhengwei pointed out that this natural substance can form a protective layer on the gastrointestinal mucosa and reduce the stimulation of the intestinal wall by foreign food or gastric acid. For people who frequently suffer from acid reflux, bloating, or gastrointestinal discomfort, moderate intake of yams can relieve discomfort and promote digestion. In addition, yam has a soft texture and is easy to digest, making it very suitable for the elderly and those with weak chewing abilities.

Polysaccharides enhance immunity Strengthen body protection

In addition to protecting the stomach and intestines, yam can also strengthen immune function. The polysaccharides contained in it can activate immune cell activity and help the body resist foreign pathogens. Wang Zhengwei mentioned that mucus protein can promote protein absorption, make full use of nutrients, and further enhance physical strength and repair power. For office workers who often work overtime, are stressed, and don’t get enough sleep, yam is a good food that can stabilize immunity and replenish energy.

And yam contains natural oligosaccharides, which have a "prebiotic" effect and can become a source of nutrients for intestinal beneficial bacteria. Long-term intake can promote the balance of intestinal bacteria and improve constipation, bloating and other problems. Intestinal health is closely related to immunity and epidemic prevention capabilities, and can even affect emotional stability and sleep quality. Therefore, eating yam regularly can not only make the gastrointestinal smoother, but also indirectly improve overall health and mental state.

Rich in potassium ions, it helps stabilize blood pressure and cardiovascular health

For modern eaters, excessive sodium intake is a common problem. Yams are rich in potassium ions, which can help the body excrete excess sodium and balance blood pressure. Wang Zhengwei suggested that moderate consumption of yam can reduce the risk of edema and hypertension, and is also helpful for cardiovascular health. Especially for those who eat out for a long time or who prefer heavy flavors, adding yam to their dishes can not only reduce the impact of sodium in the diet, but also supplement additional trace elements.

Natural antioxidant substances delay aging and fatigue

Yam contains both vitamin C and polyphenolic compounds, both of which have antioxidant capabilities and can neutralize free radicals and slow down cell aging. Wang Zhengwei said that for people who use computers for long periods of time, use their eyes too much, or work under high pressure, yam can help reduce oxidative stress and maintain physical vitality. In addition, its natural viscous ingredients help moisturize the skin and make the complexion better, achieving both health and beauty from the inside out.

Diabetics should note that portion control is the most important thing.

However, although yam is rich in nutrients, its main component is still starch, so it needs to be taken in moderation. Diabetic patients or those who need to control blood sugar should consider yam as part of their staple food and replace rice or noodles in appropriate amounts to avoid blood sugar fluctuations. Wang Zhengwei recommends consuming about half a bowl to a bowl (about 60 to 100 grams) per meal, paired with high-fiber vegetables and high-quality protein to make blood sugar rise more steadily.

If you want to maximize the nutrition of yam, you can cook it with chicken, tofu, seafood or green vegetables. Dishes such as yam chicken soup, yam tofu stew, stir-fried yam and seasonal vegetables are all healthy choices that are both delicious and nutritious. When cooking, avoid excessive frying or high-sugar seasoning to retain the original nutritional value of yam. Steaming, stewing, and boiling are all ideal cooking methods.

A healthy companion for all ages, making eating more secure

Yam is not just a "health food for the elderly", it is actually suitable for consumption by all ages. Wang Zhengwei pointed out that for growing children, it can replenish energy and help digestion; for office workers, it can relieve stress and maintain immunity; and for the elderly, it can help protect the gastrointestinal tract and stabilize blood pressure. From intestinal tract to cardiovascular, from immunity to anti-aging, yam silently protects health.
