Which formula considers both the glycemic index and the carbohydrate content to assess food's impact on blood sugar?

Glycemic Load is the concept that combines both the glycemic index of a food and its carbohydrate content, providing a more comprehensive assessment of foods’ effects on blood sugar levels. The glycemic index reflects how quickly a food causes blood sugar to rise, while glycemic load quantifies this effect by taking into account not only the type of carbohydrate but also the amount of carbohydrate in a serving. This means it offers a clearer picture of a food's actual impact on blood glucose levels relative to typical serving sizes.

For instance, a food with a high glycemic index might not significantly affect blood sugar if consumed in small amounts. Glycemic load addresses this by calculating the total carbohydrate content and providing a score that allows individuals to better manage their blood sugar levels through informed food choices.

The other options, such as caloric load, nutritional score, and insulin index, do not integrate the glycemic response with carbohydrate content in this way. Each of those concepts has its focus, but they do not specifically relate to assessing the combined effects of glycemic index and carbohydrate content on blood sugar levels as glycemic load does.
