Water chestnut, also known by many other names such as Chinese water chestnut, ground chestnut, and Chinese water chestnut, is a tuber that is not only used to prepare traditional dishes such as sweet soups and stir-fries, but it is also a commonly used medicinal herb in traditional medicine due to its cooling properties and digestive support.
Water chestnuts, scientifically known as Eleocharis dulcis Burm.f, are a type of tuber belonging to the sedge family. They commonly grow in wetlands in Asia, Africa, and some islands in the Pacific and Indian Oceans. Although not particularly flavorful, water chestnuts are highly nutritious due to their aquatic growing environment.
Water chestnuts are very low in calories and provide potassium, fiber, and antioxidants that are beneficial for cardiovascular health, digestion, and many other bodily functions. Water chestnuts can be eaten raw, juiced, or used in stir-fries without raising blood sugar levels.
From the perspective of traditional Asian medicine, water chestnuts are considered cooling, helping to reduce heat and support the body in hot and humid climates. Modern studies also show that water chestnuts have anti-inflammatory properties, contributing to weight control and improved overall health. Thanks to their high water content, they help create a feeling of fullness, provide hydration, and are suitable for people living in hot environments or engaging in a lot of outdoor activities.

2. Benefits of water chestnut
Here are four notable health benefits of water chestnuts:
2.1. Water chestnuts help protect cardiovascular health.
A diet rich in potassium is associated with a 24% reduced risk of stroke and helps control high blood pressure. Water chestnuts – a natural source of potassium – contribute to regulating sodium levels in the body, reducing the risk of heart disease and improving blood circulation.
According to information posted on the Toi website, not only the flesh but also the peel of water chestnuts contains antioxidants that can fight inflammation, help protect arterial walls, and regulate cholesterol levels. People with high blood pressure may significantly benefit from adding water chestnuts to their daily diet, especially when their diet is high in salt.
Water chestnuts are also naturally low in sodium, offering a double benefit: helping to limit water retention and supporting blood pressure regulation. Eating sliced water chestnuts daily is a simple way to reap these benefits.
2.2. Eliminating free radicals and reducing inflammation
Water chestnuts contain antioxidants such as catechins and flavonoids, which are known for their ability to eliminate free radicals – factors linked to arthritis, heart disease, and chronic illnesses.
Studies show that water chestnut extract has strong free radical scavenging capabilities and reduces inflammatory cytokine levels, thereby supporting the reduction of swelling and systemic inflammation. The peel of the water chestnut contains the most potent antioxidant compounds, helping to protect cells, limit damage, and reduce oxidative stress – one of the causes that accelerate the aging process.
Thanks to this effect, water chestnuts become a good choice for people with arthritis or inflammatory bowel disorders. The antioxidant compounds in water chestnuts can be absorbed by the body when eaten raw or boiled, and studies have noted a reduction in the accumulation of H₂O₂ (hydrogen peroxide) in cells. H₂O₂ is a type of reactive oxygen species (ROS) that the body produces during metabolism. At low levels, H₂O₂ participates in several normal physiological activities. But if H₂O₂ accumulates too much, it causes oxidative stress, damaging cells, promoting inflammation and aging, and even being linked to chronic diseases.
When consumed with green vegetables, the anti-inflammatory effects of water chestnuts are further enhanced.
2. 3. Supports digestion and relieves constipation
Water chestnuts have a low FODMAP index, making them friendly to people with irritable bowel syndrome (IBS). They don't cause bloating because they contain few indigestible carbohydrates. The fiber in water chestnuts helps nourish beneficial bacteria in the gut, contributing to improved digestive health.
Soluble fiber acts as a "binding agent" for cholesterol, helping to link digestive function and cardiovascular health. Water chestnuts also help retain water in the intestines, soften stool, and support smooth bowel movements, reducing discomfort.
In traditional medicine, water chestnut juice is used to enhance the function of the spleen and help improve appetite in both children and adults. Scientific observations also show that water chestnuts help the colon function more efficiently, making them a suitable food for controlling constipation without causing weight gain.
2.4. May support weight management.
Thanks to its low calorie content but high water content (about 90%) and fiber, water chestnuts create a feeling of fullness quickly, helping to limit food intake. This is especially beneficial for people on a weight-loss diet.
The fiber content in water chestnuts helps stabilize blood sugar, curb sudden hunger pangs, and reduce cravings for high-energy foods. With their crunchy texture, water chestnuts can be a healthy snack, replacing alternatives like potato chips.
The potassium in water chestnuts also supports the elimination of excess fluid from the body, contributing to healthy weight management. Studies show that a high-fiber, low-calorie diet improves energy metabolism and supports long-term weight maintenance.
Water chestnuts can be added to salads, stir-fries, or dishes with lots of vegetables, increasing the volume of the dish without increasing the total calorie count.
Furthermore, water chestnuts are known to possess anti-cancer properties, capable of inhibiting tumor growth. At the same time, water chestnuts help combat oxidative stress – a factor linked to the development of type 2 diabetes and many other chronic diseases.
