Toor dal has a glycemic index of 22. Moong dal has a glycemic index of 25–28. Chana dal has a glycemic index of 8–11. These are among the lowest GI values of any food on earth — lower than steel-cut oats, lower than quinoa, lower than most vegetables. Yet we treat dal as a side dish to rice, when it is arguably the most nutritionally sophisticated element on the thali.
The protein picture
India's 500 million vegetarians get most of their protein from dals. Toor dal provides 21–23g per 100g. Moong provides 23–24g. Urad dal provides 24–25g. Combined with rice — which provides the amino acids (particularly methionine) that legumes lack — dal-rice creates a complete protein matching meat in amino acid proportions. This is not a coincidence of Indian cuisine; it is a nutritional technology developed over millennia.
“The combination of dal and rice is not tradition for its own sake. It is precision nutrition — two incomplete proteins that together make one complete one.”
The folate dimension
Toor dal carries 568µg of folate per 100g — among the highest of any commonly eaten Indian food. Moong dal contains 625µg (sprouted). India's traditional meal pattern of dal twice daily provides a substantial portion of the recommended 400µg/day of folate without anyone consciously thinking about supplementation. This is why traditional Indian diets, despite being predominantly plant-based, show good pregnancy outcomes when maintained.
- Add a tadka of mustard oil + cumin + turmeric to any dal — the fat improves absorption of fat-soluble vitamins.
- Squeeze lemon over dal just before serving — this doubles available iron from the meal.
- Moong dal khichdi (with rice and ghee) is the Ayurvedic hospital food — complete protein, low GI, easily digested.
- Sprouted moong provides even more folate and destroys phytic acid — a nutritional upgrade from cooked moong.
