Question: 1 / 400

Which nutrient lowers the insulin response to a meal?

Proteins

Carbohydrates

Sugars

Fiber

Fiber is the nutrient that significantly influences the insulin response to meals. When fiber is present in food, it slows down digestion and the absorption of carbohydrates. This gradual release of glucose into the bloodstream helps prevent sharp spikes in blood sugar levels, ultimately leading to a more stable and controlled insulin release.

High-fiber foods, such as fruits, vegetables, whole grains, and legumes, not only promote satiety but also enhance glycemic control. This is particularly beneficial for individuals who are looking to manage blood sugar levels, such as those with insulin resistance or type 2 diabetes. Fiber-rich diets help maintain balanced energy levels and can reduce the risk of metabolic issues over time. Therefore, incorporating fiber into meals can be a powerful strategy for managing insulin responses effectively.
