Aspartame from artificially-sweetened soft drinks can linger in the digestive tract for 2 hours or more after ingestion, triggering insulin secretion long after the sweetener is swallowed. This, in turn, can cause blood glucose to drop resulting in appetite surges that nullify the alleged weight management benefits of the widely popular artificial sweetener. That’s the conclusion of a new study by Brasilian researchers who looked at the effects of aspartame-sweetened drinks, compared with regular sucrose-sweetened drinks, plain water, and water containing sweeteners. The findings have important implications for people who believe they’re doing their health a favor by choosing “no-calorie” aspartame-sweetened products. scales.
