In the realm of traditional Indian fasting foods, water chestnut flour—known as singhada atta in Hindi—holds a special place. Celebrated not only for its ease of digestion but also for its rich nutritional and medicinal properties, this humble flour has been used for centuries as a vital ingredient during vrat (fasting) and upvaas (religious fasts).

Ayurveda, the ancient Indian system of medicine, extols water chestnut flour as a powerhouse of minerals and alkalis, making it a treasure trove of nourishment that supports overall health.

What is water chestnut flour?

Water chestnuts are aquatic tubers harvested from the roots of a plant called Trapa natans. These crunchy, white tubers grow in fresh water lakes and ponds and are widely consumed across Asia.

When dried and ground, they form water chestnut flour—a gluten-free, light, and easily digestible flour that has gained popularity not just in fasting rituals but also among health-conscious individuals today.

Nutritional Profile

According to Ayurvedic scholar Acharya Balkrishna, water chestnut flour contains approximately 22% more mineral salts and alkaline elements than buffalo milk.

This remarkable mineral content includes essential elements such as potassium, magnesium, iron, and calcium. These minerals play a key role in maintaining the body’s electrolyte balance, supporting nerve function, and strengthening bones.

Moreover, the flour is low in fat, cholesterol-free, and contains a good amount of dietary fiber. This makes it an excellent choice for those seeking to manage their weight, improve digestion, and maintain a balanced blood sugar level.

Health benefits backed by ayurveda and modern science

Ayurveda highlights several medicinal properties of this flour. It is said to have shita (cooling) properties, which help balance pitta dosha (the fire element responsible for metabolism and inflammation in the body). Its natural alkalis help neutralize acidity and soothe the digestive tract.

Here are some notable health benefits attributed to water chestnut flour:

Blood Sugar Regulation: The fiber content slows down the absorption of sugars, making it beneficial for those managing diabetes or at risk of blood sugar spikes.

Heart Health: The high potassium content aids in controlling blood pressure, reducing strain on the heart, and supporting cardiovascular health.

Anti-inflammatory Effects: Regular consumption may help reduce inflammation associated with arthritis (gathiya), ulcers, and other chronic inflammatory conditions.

Digestive Health: Its alkaline nature helps maintain stomach pH balance and prevents acidity and ulcers.

Hydration and Detoxification: Water chestnuts are composed mostly of water, making the flour hydrating and helpful in flushing out toxins from the body.

Traditionally, water chestnut flour is a staple during fasts, especially in Hindu culture, because it provides energy without breaking the fast’s dietary rules (which exclude grains, lentils, and other staples).

It is often mixed with water or milk to make pancakes (singhare ke atte ka cheela), dumplings, or even sweets.

While water chestnut flour is generally safe and beneficial for most people, those with specific allergies or sensitivities should introduce it gradually. Also, because of its high fiber content, excessive consumption may cause digestive discomfort in some individuals.
