Frequently Asked Questions
Yes, but choose wisely. Avoid white rice completely. Choose brown rice, red rice, or basmati rice (all in moderation โ max 1/2 cup per meal). Better alternatives: quinoa, millets, or cauliflower rice.
Yes, but choose the right flour. Best: Jowar roti, bajra roti, ragi roti, or multigrain roti (no maida). Limit to 2 rotis per meal. Avoid plain wheat roti in large quantities.
In moderation. Bananas have GI 62 (medium). Eat only small, slightly green bananas (less ripe = lower sugar). Limit to half a banana at a time.
No! Jaggery is still sugar (about 85% sucrose). It raises blood sugar almost as much as white sugar. Avoid both. Use stevia or monk fruit if you need sweetness.
Limit strictly. Potatoes have high GI (78-85). If eating, eat small portion with skin (fiber), boiled not fried, and pair with protein and vegetables to slow absorption.
High protein + high fiber + low sugar. Examples: Vegetable oats upma + 1 boiled egg, moong dal chilla + mint chutney, ragi porridge + nuts, Greek yogurt + berries + flaxseeds.
