Barley vs Oats

Before oats became the poster child of healthy eating in India, there was barley. Or more specifically, barley water.

For many Indians who grew up in the 1980s and 90s, barley water was not a wellness trend but a household remedy. It appeared during hot summers, fevers, upset stomachs, and doctor-advised “light diets.”

Known locally as jau, it has been part of Indian food traditions for centuries, especially in Rajasthan, Punjab, Haryana, and parts of the Himalayan region. Long before oats became the face of “healthy breakfast food,” barley was already being used in rotis, porridges, sattu-like drinks, soups, and even temple offerings.

Yet somewhere along the way, it lost the spotlight to shinier imported grains and aggressively marketed breakfast cereals.

Barley is generally lower (28) on the glycemic index than oats (59), so it tends to raise blood sugar more slowly. Barley is rich in fibre, especially beta-glucan, which supports heart health, digestion, and blood sugar control. It is filling, affordable, and remarkably suited to India’s climate.

Common types of Barley:

Hulled barley like Brown Rice is the less processed form: only the tough inedible outer hull is removed, so it keeps more bran and nutrients and is considered a whole grain. 

Pearl barley like White Rice is more processed: the hull and most or all of the bran layer are removed, which makes it cook faster but lowers fiber and nutrient content.

In plain terms

• Hulled barley: chewier, nuttier, slower to cook, more nutritious.
• Pearl barley: softer, lighter, faster to cook, less fiber.

For drinking as barley water

If you want the drink to be more “whole grain” and nutrient-rich, hulled is the better pick. If you want something quicker and smoother, pearl is easier.

Barley water is usually safe in normal food amounts, but grinding it can make it stronger and heavier.

Ground barley exposes more surface area, so water can pull out more of the soluble material faster. If you drink it unstrained, you keep more of the suspended fiber, which is one reason barley water is often linked with digestion and fullness. The drink becomes murkier and may feel heavier than barley boiled whole.

Lightly crush the barley, boil it, then strain if you want a lighter drink.

Main precautions

• Gluten: barley contains gluten, so avoid it if you have celiac disease or gluten sensitivity.
• Digestive upset: a more concentrated drink, especially from ground barley, can cause gas, bloating, constipation, loose stools, or stomach discomfort in some people.
• Allergy: some people may be allergic to barley or other cereal grains.
• Blood sugar: barley may lower blood sugar, so people on diabetes medicines should be careful and monitor levels.
• Before surgery: barley can affect blood sugar control, so it may need to be stopped ahead of surgery.

Barley’s unique mix of fiber and compounds supports digestive health and has a pleasant, nutty chew when cooked. It is great for traditional Indian recipes like vegetable dalia or khichdi.
