How Different Cooking Methods Change the Glycemic Index of Indian Foods

The way you cook Indian food can change its glycemic index quite a bit. Boiling, steaming, roasting, frying, and even storing food after cooking can all affect how quickly starch turns into glucose in the body. That means the same ingredient may behave very differently on your plate depending on how it is prepared.

Boiling and steaming are often better than deep frying because they usually preserve more water and can increase the amount of slowly digestible starch in some foods. For example, common Indian wheat products like dalia and chapati can have a lower glycemic impact than fried options such as poori, especially when they are freshly cooked and not overloaded with oil. In rice, cooking style also matters: one study found microwave-cooked basmati rice had a lower GI than rice cooked in a rice cooker.

Deep frying can make foods more calorie-dense and may reduce resistant starch, which can lead to a faster glucose rise. This is why foods like puri, bhatura, pakora, and fried snacks are more likely to spike blood sugar than boiled or lightly roasted versions of similar ingredients. Even when the ingredient is the same, the cooking method can change the body’s response.

Cooling cooked foods can also help. Stored wheat products showed more resistant starch and a lower glycemic response compared with freshly prepared ones in one study. That is one reason why leftover rice or cooled starch-based foods may sometimes raise blood sugar more slowly than freshly cooked versions, though portion size still matters.pubmed.ncbi.nlm.nih

For daily eating, the best approach is to choose gentler cooking methods more often. Boil, steam, roast, or lightly sauté when possible, and pair carbs with protein, vegetables, and fiber to slow glucose absorption. A simple meal of chapati, dal, and sabzi is usually more blood-sugar-friendly than a meal of fried breads and potato-heavy sides.
