Water chestnuts contain no cholesterol, making them suitable for people with heart diseases.


According to the study, water chestnuts contain flavonoids, such as anthocyanin, isoflavones, and flavonols, with potent antioxidant activities. These antioxidants protect your cells from free radical damage linked to various chronic diseases; they can also inhibit the α-glucosidase enzyme.

Water chestnuts may be effective against several types of cancer. According to the study, flavanoids can effectively block the growth of these cells [1].

Non-starch polysaccharides

According to research, water chestnuts are high in non-starch polysaccharides, contributing to antioxidation. Besides, insoluble non-starch polysaccharides are effective laxatives, such as cellulose and hemicellulose. These compounds can lower plasma cholesterol levels while also helping to normalize blood glucose and insulin levels, making these polysaccharides a part of dietary plans to treat cardiovascular disease and Type 2 diabetes [2].


Water chestnuts have a high total phenolic content. Gallocatechin gallate, epicatechin gallate, and catechin gallate are the main phenolic compounds in water chestnuts. They also contain anthocyanins, proanthocyanidins, and isoflavones in low amounts.

These compounds have potent antioxidant properties and have been shown to protect against free radical-related diseases such as CVD and cancer [1].


Puchiin is a bacteriostatic substance found primarily in water chestnuts. It has been known for a long time and is considered the second plant-derived antibacterial substance after penicillin.

Puchiin has potent antibacterial properties and functions similarly to penicillin in aiding immune function. Although puchiin has been reported for a long time, the qualification and quantification of antibacterial activity-contributed components remain limited [1].


Water chestnut consumption daily significantly reduced total and LDL ("bad") cholesterol levels. According to the study, water chestnuts contain brassicasterol, coprostanol, and beta-sitosterol. Beta-sitosterol can lower blood cholesterol levels because it competes with cholesterol absorption in the body [1].


Water chestnuts are alkaline. The pH value of water chestnuts falls from 6.7 to 8.2. The acidity of water chestnut can also be measured by looking at its potential renal acid load or PRAL value. Water chestnuts have a PRAL value of -10, making them an alkaline-promoting food. The lower this number is, the more alkaline the food produces inside the body.

Health checks

Low in Cholesterol
 ⓘ Dietary cholesterol is not associated with an increased risk of coronary heart disease in healthy individuals. However, dietary cholesterol is common in foods that are high in harmful saturated fats.
No Trans Fats
 ⓘ Trans fat consumption increases the risk of cardiovascular disease and mortality by negatively affecting blood lipid levels.
Low in Saturated Fats
 ⓘ Saturated fat intake can raise total cholesterol and LDL (low-density lipoprotein) levels, leading to an increased risk of atherosclerosis. Dietary guidelines recommend limiting saturated fats to under 10% of calories a day.
Low in Sodium
 ⓘ Increased sodium consumption leads to elevated blood pressure.
Low in Sugars
 ⓘ While the consumption of moderate amounts of added sugars is not detrimental to health, an excessive intake can increase the risk of obesity, and therefore, diabetes.
