Here’s how to slash sugar spikes from pasta — and make it healthier.
Scientists discover that cooling cooked pasta for 24 hours transforms its starch into a gut-friendly fiber that slashes blood sugar spikes.
When you cook pasta and then cool it for at least 24 hours, the starch molecules undergo a process called retrogradation. This molecular reorganization transforms digestible starch into "resistant starch," which functions more like fiber than a simple carbohydrate. Instead of being rapidly absorbed in the small intestine and causing a sharp rise in glucose, it travels to the large intestine where it feeds beneficial gut bacteria as a powerful prebiotic. This simple kitchen hack not only supports a healthy microbiome but also encourages the production of short-chain fatty acids that help reduce internal inflammation.
Beyond gut health, this transformation provides a significant advantage for metabolic wellness by slowing sugar absorption and improving insulin response. Perhaps most surprisingly, these health benefits remain largely intact even if you choose to reheat the pasta before eating. By simply planning ahead and refrigerating your noodles overnight, you can effectively lower the caloric impact of your meal while maintaining more stable energy levels throughout the day. This game-changing strategy allows you to enjoy favorite comfort foods while prioritizing long-term health and better blood sugar control.
