New research suggests that aspartame, a common artificial sweetener, might increase the risk of heart disease by causing insulin levels to spike. A study with mice found that aspartame led to fatty deposits in arteries, which can contribute to heart attacks and strokes. Aspartame is found in many low-calorie diet products like sodas and desserts because it's much sweeter than sugar and used in smaller amounts.
The study, published in Cell Metabolism, shows that aspartame doesn't just cause a temporary increase in insulin but can keep insulin levels high over time. This prolonged high insulin can lead to insulin resistance, a major risk factor for Type 2 diabetes and heart disease. While aspartame is marketed as a healthier alternative to sugar, its impact on insulin and inflammation might suggest otherwise.
Experts now recommend being cautious with aspartame, especially for those at risk for heart and diabetic health issues. Although aspartame is considered safe in moderation, these new findings point to possible long-term risks from regular use. Until further studies are done, sticking to a diet with fewer artificial sweeteners and more whole foods might be a safer choice.
