Even though they are called chestnuts, water chestnuts aren’t really nuts. Growing in marshes, ponds, paddy fields and shallow lakes, water chestnuts are aquatic tuber vegetables. They originate from Australia, Africa, Southeast Asia, Southern China, Taiwan, and several islands in the Indian and Pacific oceans. Water chestnuts are harvested once their bulbs turn dark brown.

Water Chestnuts Benefits

Water chestnuts are a store house of nutrients and have a number of health benefits.

1. Nutritious and low-calorie count

Full of nutrients, 3.5-ounces of raw water chestnuts contain:

  • Calories: 97
  • Fat: 0.1 grams
  • Carbs: 23.9 grams
  • Fibre: 3 grams
  • Protein: 2 grams
  • Potassium: 17% of the RDI
  • Manganese: 17% of the RDI
  • Copper: 16% of the RDI
  • Vitamin B6: 16% of the RDI
  • Riboflavin: 12% of the RDI

Being an impressive source of Fibre, water chestnuts contain Fibre which fulfils 12% of the daily Fibre recommendation for women and 8% for men. Water chestnuts are rich in Riboflavin that helps in reducing oxidative stress and eliminates inflammation of nerves.

2. High content of Disease-Fighting Antioxidants

Water chestnuts are rich in antioxidants, which are molecules that help shield the body against potentially damaging molecules known as free radicals. The accumulation of free radicals in the body can overwhelm the body’s natural defences and lead to an undesired state called oxidative stress.

Oxidative stress has been associated with higher chances of chronic diseases such as heart disease, type 2 diabetes and various types of cancers. Water chestnuts have an abundance of antioxidants known as catechin gallate, epicatechin gallate, ferulic acid, and gallocatechin gallate.

3. Lower Blood Pressure and Reduce the Risk of Heart Disease

Factors such as high blood pressure, high blood cholesterol (LDL cholesterol), strokes and high blood triglycerides increase the chances of getting heart disease.

Historically, water chestnuts have been used to treat conditions like high blood pressure because they are rich in potassium. Several studies conclude that diets rich in potassium lower the chances of stroke and high blood pressure — two of the major risk factors for heart disease.

Chilli Water Chestnut

Essentially an Indo-Chinese dish, Chilli Water Chestnut is pretty famous in India. It is made by deep frying water chestnuts and tossing them in an Indo-Chinese sauce. This sauce gives the water chestnuts a mouth-watering, spicy, umami flavour.

A resourceful root vegetable, water chestnuts have high water content. They are widely used in Indian and Southeast Asia cooking – either raw or cooked. Water chestnuts are called so because their shape is similar to that of a chestnut in shape along with a thin brown skin that covers its white flesh. 

Surprisingly, a water chestnut has almost the same potassium content as a banana!  Furthermore, water chestnuts also contain Fibre, vitamin B-6 and a small proportion of protein. The crunchy water chestnut has a mild sweetness that makes it a unique ingredient. 

The texture and taste of water chestnuts resemble that of a lotus root. Water chestnuts can be used to make lip-smacking dishes as they retain their crunchiness even after they are fried. After coating in a batter, water chestnuts are deep fried before being tossed in an Indo-Chinese sauce. Simple, yet delectable and an ideal appetizer.
