A Detailed Explanation of the Benefits and Effects of Water Chestnut, Plus Its Nutritional Value and Ways to Eat It

The water chestnut, commonly known as matai or dili, is a corm-type vegetable that grows in paddy fields or shallow water. Its outer skin is purple-black, its flesh is pure white, and its texture is crisp and juicy with a sweet taste. It can be eaten raw as a fruit or cooked in dishes and soups. It is commonly seen in wet markets in the south and is a familiar ingredient on many family dining tables.

From a traditional perspective, the water chestnut is cool in nature and sweet in taste. In folk practice, it is often boiled with sugarcane, snow pear and the like; when the weather is dry and the throat feels uncomfortable, drinking a bowl of it is believed to clear heat, promote body fluids, soothe the throat and relieve dryness. Nutritionally, the water chestnut has a high water content and also contains dietary fiber and minerals such as potassium and phosphorus. It is low in fat and not high in calories, making it suitable as a supplement to the daily diet.

In terms of ways to eat it, the water chestnut is quite versatile. After peeling, it can be eaten directly as a fruit, or chopped and mixed into meat filling to add a fresh, sweet taste, or stewed in soup with pork ribs and corn. It is also uniquely flavorful when made into snacks such as water chestnut cake and water chestnut jelly. After cooking, its texture becomes somewhat softer and glutinous, making it more suitable for people whose stomach and intestines are sensitive to cold.

It should be noted that water chestnuts grow in the mud underwater, and their skins may carry bacteria or parasites. Before eating them raw, they must be washed clean and peeled; eating them cooked is safer. They are cool in nature, so people with weak and cold spleen and stomach or those prone to diarrhea should not eat too many. In addition, the water chestnut is only an ordinary food ingredient and cannot replace medication; when feeling unwell, one should still seek medical attention promptly.
