Bananas (1 Medium (7 Inches To 7 7/8 Inches Long)) and Idli (1 Piece)

Reduce the banana portion to half a small banana, and eat it only after a meal rather than on an empty stomach.

Pair banana or idli with protein and fat, such as eggs, tofu, plain Greek yogurt, or natural peanut butter, to slow absorption.

Limit idli to a smaller serving and add a larger portion of sambar with extra non-starchy vegetables such as spinach, okra, cabbage, or cauliflower.

Choose berries, apple, pear, or orange as a lower-spike fruit alternative to banana; keep portions moderate.

Take a 10–20 minute easy walk soon after eating, especially after meals containing idli or banana.

Track your glucose response to different portions and meal combinations, since preparation, ripeness of banana, and individual response can vary.
