Water chestnut, also known as elephant yam, is a type of aquatic tuber that grows in wet environments such as swamps, ponds, marshes, and paddy fields. This tuber is widely present in countries in Southeast Asia, continental Africa, Australia, and numerous islands in the Pacific and Indian Ocean regions.
The exterior of the water chestnut is covered by a brown, hard shell, while the inner flesh is white, crisp, and contains a lot of water, giving it a refreshing sweet taste. Water chestnuts can be eaten immediately after peeling or used as an ingredient in various cooking recipes such as stir-fries, desserts, cakes, or added to salads. Although water chestnuts are an essential part of Vietnamese cuisine, not everyone is aware of the health benefits they bring.
In traditional Asian medicine, water chestnuts are highly regarded for their multiple uses, such as detoxification, liver cooling, digestive system enhancement, hemostasis, alcohol detoxification, and diuretic effects. They are also used to treat heat-related illnesses such as mouth ulcers, diarrhea, and support the treatment of cardiovascular and diabetes-related diseases. These benefits have been studied and confirmed by modern medicine.

Blood pressure reduction and heart disease risk
Heart disease is recognized by the CDC as a leading cause of death worldwide, with high blood pressure, increased cholesterol levels, and stroke being contributing factors.
Studies have shown that a potassium-rich diet can help reduce this risk, especially reducing blood pressure and preventing strokes. Water chestnuts, with their high potassium content, emerge as a beneficial natural food source. Incorporating water chestnuts into regular meals can help control blood pressure and reduce the risk of heart disease.

Improving digestive health
In every half cup of water chestnuts, you will receive about 1.9g of fiber, contributing to 7% of the recommended daily fiber intake. According to recommendations from Mayo Clinic, men under 50 years old need about 38g and women need 25g of fiber daily. Men over 51 years old need about 30g, while women of the same age need about 21g. Fiber has important benefits in stimulating intestinal peristalsis and supporting the growth of beneficial bacteria in the intestines to avoid constipation.
Notes when using water chestnuts
Water chestnuts are safe and non-toxic. However, due to the cool nature of water chestnuts, they may not be suitable for people with cold constitutions or those who have conditions such as cold hands and feet, and are prone to catching colds. For diabetic patients, it is advisable to prioritize consuming natural water chestnuts without adding sweeteners to control blood glucose levels.
