GI Index — Grains and Cereals

Glycemic Index of Indian Grains — The Complete Table

The glycemic index of Indian grains varies enormously — from white rice at GI 72 to parboiled rice at GI 38. Understanding the glycemic index of Indian grains you eat every day is one of the most impactful pieces of nutrition knowledge an Indian can have, because small grain substitutions can make a significant difference to daily blood sugar patterns.

Glycemic Index of Indian Grains — Complete Table

Food GI Value Category Notes
White rice (boiled) 72 High GI India’s most consumed grain
Brown rice 55 Low GI (borderline) Slightly lower glycemic index than white
Parboiled rice (ukda chawal) 38 to 45 Low GI Lowest glycemic index rice — underrated
Basmati rice (white) 50 to 58 Low to Medium GI Lower glycemic index than regular white rice
Whole wheat chapati 62 Medium GI Standard roti
Maida roti / naan 75 High GI Refined flour — high glycemic index
Multigrain atta roti ~52 Low GI Lower glycemic index option
Oats (rolled) 55 Low GI Best low glycemic index breakfast option
Oats (instant) 66 Medium GI Processing raises glycemic index
Bajra (pearl millet) roti 54 Low GI Excellent low glycemic index grain
Jowar (sorghum) roti 53 Low GI Another excellent low glycemic index option
Ragi (finger millet) 68 Medium GI Often assumed low GI — actually medium
Foxtail millet 50 Low GI One of the lower glycemic index millets
Poha (flattened rice) 70 High GI Common breakfast — high glycemic index
Idli 77 High GI High glycemic index despite fermentation
Dosa (plain) 67 Medium GI Better than idli; pair with sambar
Upma (semolina) 66 Medium GI Semolina is medium glycemic index
White bread 75 High GI Refined flour — high glycemic index
Multigrain bread 52 Low GI Much lower glycemic index than white bread
Cornflakes 81 High GI Highest glycemic index breakfast option

Parboiled Rice — The Lowest Glycemic Index Rice in India

The glycemic index of parboiled rice (ukda chawal) is 38 to 45 — dramatically lower than regular white rice at 72. Parboiled rice is a staple in Tamil Nadu, Andhra Pradesh, and Bengal and is one of the most underrated low glycemic index grains in India. Parboiling changes the starch structure of the rice in a way that significantly slows digestion, hence the much lower glycemic index. If you eat rice daily, switching to parboiled rice is the single highest-impact dietary change you can make for your glycemic index intake.

The Idli Glycemic Index Surprise

The glycemic index of idli is approximately 77 — firmly high GI. Many people assume fermentation lowers idli’s glycemic index significantly. In reality, fermentation improves digestibility and nutrition but does not dramatically reduce the glycemic index response. Pairing idli with sambar — which is high in protein and fibre — helps moderate the overall meal glycemic index considerably. Always eat idli with sambar, not just chutney.

Ragi Glycemic Index — The Misconception

The glycemic index of ragi (finger millet) is approximately 68 — medium GI, not low GI. Ragi is widely promoted as a health food and assumed to have a low glycemic index. While ragi is genuinely nutritious — high in calcium and iron — its glycemic index of 68 places it in the medium category. People specifically managing their glycemic index intake should be aware that ragi is not a low GI food.

How to Lower the Glycemic Index of Rice at Home

Cooked rice that has been cooled and then reheated has a meaningfully lower glycemic index than freshly cooked rice. Cooling converts some digestible starch into resistant starch, which slows glucose absorption. Yesterday’s reheated rice is genuinely lower glycemic index than freshly cooked rice — a simple, zero-cost way to reduce your daily glycemic index intake from rice.

Best Low Glycemic Index Grain Choices for Indians

The best low glycemic index grain choices for Indians are: parboiled rice (GI 38 to 45), foxtail millet (GI 50), basmati rice (GI 50 to 58), jowar roti (GI 53), bajra roti (GI 54), rolled oats (GI 55), and multigrain atta roti (GI approximately 52). Switching from regular white rice to parboiled rice is the biggest single improvement available to most Indians.
