💡 Cool & Reheat
Cooked-and-cooled starches form resistant starch, which resists digestion and reduces the glycemic response. Refrigerate and reheat before eating — the effect persists.
💡 Half Portion, Full Satisfaction
A half serving significantly reduces the glycemic load. Use it as a side, not the main event, and bulk up your plate with vegetables.
💡 Balance Sodium
Pair with low-sodium foods throughout the rest of your day. Fresh herbs and spices can replace salt as flavoring.
