Water chestnuts benefits might not be the first thing that comes to mind when shaking up your diet, but for home cooks and health-focused readers, these crunchy aquatic vegetables deserve a second look. If you’ve ever wanted a unique ingredient that’s low in calories, high in fiber, and surprisingly versatile, water chestnuts check all the boxes. For a deeper look at their nutritional breakdown, take a peek at our Water Chestnuts: Benefits, Nutrition, and Risks resource.
1) Crisp, Low-Calorie Goodness
One of the biggest surprises about water chestnuts is how they manage to stay crunchy even when cooked. This crispness is attributed to ferulic acid—a naturally occurring compound that helps preserve texture. According to 1, water chestnuts are around 74% water yet deliver a solid dose of vitamins and minerals.
A 100-gram serving has only 97 calories, making it a smart pick for anyone hoping to keep mealtime interesting without piling on extra energy intake. That same 100-gram portion provides about 584 milligrams of potassium, plus valuable nutrients like manganese and copper 1. Combined with their mild taste, water chestnuts are an effortless add-on for meals that need a nutritious crunch.
Even better, they offer more bang for your buck than many high-calorie snack foods. You can munch on them raw, just like you would a crisp apple slice, or toss them in a variety of dishes without losing their signature texture.
2) Helpful Ally for Weight Management
Because they’re low in calories yet provide decent amounts of fiber, water chestnuts can be an ally if you’re monitoring your weight. Fiber adds bulk to your diet and can prompt a greater sense of fullness, which may mean fewer temptations to overeat. This strategy aligns well with what dietitians often recommend for appetite control.
They also have virtually no fat and roughly 24 grams of carbohydrates per 100-gram serving, which is modest compared to many other starchy vegetables 1. Adding water chestnuts to soups, stir-fries, or salads is a simple way to keep meals satisfying without going overboard on calorie intake. If you’re curious about additional ways to manage water weight or minimize bloating, consider these strategies for curbing unwanted water weight.
The beauty of water chestnuts is that they require little prep. You can peel and slice them raw for a crunchy snack, or buy them pre-peeled and canned for a hassle-free kitchen staple.
3) High Antioxidant Content
When it comes to antioxidant properties, water chestnuts pack more benefits than many realize. They boast compounds such as ferulic acid, gallocatechin gallate, and epicatechin gallate—all of which help the body combat damaging free radicals 1. Over time, free radicals can lead to oxidative stress, which contributes to aging and various health issues.
The peel contains a notable concentration of these protective antioxidants, though the flesh remains a viable source too. According to 2, introducing antioxidant-rich foods—like water chestnuts—into your diet may provide an added layer of defense for your cells.
In practical terms, these antioxidants can support your overall well-being in much the same way as those found in popular superfoods. While more research is always helpful, many nutrition experts point to antioxidant-rich items as crucial players in keeping the body functioning optimally.
4) Heart-Friendly Nutrients
Low in sodium and brimming with potassium, water chestnuts have a favorable nutrient profile for heart health. Potassium is linked to smoother blood pressure regulation, and higher potassium intakes have been associated with a reduced risk of stroke 2. Dishes that include water chestnuts can be especially helpful if you’re watching your salt intake.
The antioxidants in water chestnuts also shield cells from oxidative stress, which may indirectly support cardiovascular well-being 1. Because water chestnuts are low in saturated fat, they align with heart-friendly dietary guidelines that focus on lean protein, whole grains, fruits, and vegetables.
If you’re looking to keep your blood pressure in check by staying hydrated, you can also review topics such as the link between dehydration and blood pressure to make informed decisions about overall health.
5) Supports Digestive Health
The fiber found in water chestnuts, about 3 grams per 100-gram serving, can play a significant role in promoting healthy digestion 3. Foods rich in fiber not only encourage regular bowel movements but also help maintain a diverse community of beneficial gut bacteria.
Another health perk is their classification as a low FODMAP food in many cases 2. Low FODMAP foods may be gentler for individuals managing issues such as irritable bowel syndrome. When combined with other gut-friendly choices, water chestnuts can help keep your digestive tract on the right track without sacrificing flavor or variety.
Additionally, some research points toward prebiotic-like effects, suggesting that water chestnut extracts might encourage the growth of beneficial bacteria in the long term. While research is ongoing, the possibility makes these aquatic veggies even more appealing.
Potential Concerns & Precautions
Water chestnuts are generally well-tolerated. However, they can trigger sensitivities in rare cases. If you notice unusual bloating or GI discomfort, consider talking to a healthcare professional.
Also, keep in mind the difference between water chestnuts (Eleocharis dulcis) and chestnuts from trees—these are not the same food. Double-check product labels when you’re trying something new.

As with any food, it’s best to rinse canned versions before cooking or eating to reduce sodium if you’re aiming to keep blood pressure levels in a healthy range.
How to Use Water Chestnuts
Water chestnuts bring an appealing crunch to a number of meals, whether raw or cooked. If you’re looking for specific preparation ideas, here are a few options:
- Raw Slices: Peel and slice them for a crisp snack, or add the slices to salads for extra texture.
- Stir-Fries: Toss them into vegetable or meat-based stir-fries near the end of cooking to keep the crunch intact.
- Dips and Sauces: Blend finely diced water chestnuts into dips or salsas for extra crispness.
- Soups and Stews: Add them to soups for a surprise bite that doesn’t overwhelm the flavor.
- Low-Carb Substitute: Use thin slices in place of crackers or bread for small toppings at appetizer stations.
In many Asian cuisines, water chestnuts are a popular textural component for dumplings or spring rolls. You can also find water chestnut flour in specialty stores, often used in gluten-free baking or as a thickener for soups and gravies.
