Water Chestnut Nutrients
A half-cup of water chestnuts contain 10 percent of the daily value of each of the following: potassium, copper, B6 and manganese. Other nutrients in water chestnuts include thiamine, riboflavin, vitamins C and E, magnesium, phosphorus and zinc, according to Self Nutrition Data. Each of these minerals play a role in your overall health. Vitamin B6 supports healthy brain and immune system function, while thiamine and riboflavin help your body convert food into energy. Your heartbeat maintains a steady rhythm with the help of potassium, while copper aids in red blood cell production. Manganese helps build bones and also aids in metabolizing carbohydrates and cholesterol, says Harvard Medical School.
Low-Calorie Choice for Diets
Water chestnuts have only 60 calories in one-half cup, probably due to their high water content, so you don't have to worry about eating a little more of this nutritious vegetable if you are counting calories. Choose water chestnuts for a healthy low-calorie snack while sticking to your diet.
Fiber for Healthy Digestion
With 1.9 grams of dietary fiber, water chestnuts supply 7 percent of your daily value per half-cup serving. Men younger than age 50 need 38 grams of fiber each day, and women under age 50 should consume 25 grams, according to the Mayo Clinic. Men older than 51 years of age should aim for 30 grams, while women the same age should try to get 31 grams per day. Fiber is not only necessary for maintaining bowel health; it also helps lower cholesterol levels, assists in weight loss, helps stabilize blood sugar and lowers blood pressure.

Antioxidants to Fight Free Radicals
Water chestnuts have antioxidant characteristics due to a number of compounds they contain. One of these antioxidants is called ferulic acid, says Healthline. Ferulic acid has shown an effect on neutralizing free radicals involved in chronic diseases. This was proven by a 2016 test-tube study that investigated the anti-tumor activity of ferulic acid in breast cancer. Results of the study, published in Oncology Reports, found that ferulic acid helped to not only suppress the growth, but kill breast cancer cells, too.
Another natural antioxidant in water chestnuts is flavonoid. Flavonoids have also shown to have free radical-scavenging activity and disease-fighting capabilities. A 2016 Journal of Food Science study used Chinese water chestnut peel extract to conclude that water chestnut extract has an anti-tumor and antioxidant effect and helps to scavenge nitrates.
