Do natural sweeteners like maple syrup affect insulin levels?

Yes, even natural sweeteners like maple syrup can raise insulin levels, impacting metabolic health.

What is the insulin index and how does it differ from the glycemic index?

The insulin index measures how foods affect insulin levels, while the glycemic index measures blood sugar impact.

Sweetener Shock: 'Healthy' Options Can Spike Insulin

Natural sweeteners, including maple syrup, honey, and agave nectar, are often promoted as healthier alternatives to regular sugar. However, health experts emphasize that their natural origin does not automatically equate to metabolic benefits. These sweeteners can still significantly impact insulin levels, a crucial factor for long-term health. Understanding the difference between the glycemic index and the insulin index is vital for making informed dietary choices.

The glycemic index measures how quickly carbohydrates raise blood sugar, while the insulin index assesses a food's effect on insulin release. Some foods with a low glycemic index, like agave nectar, can still trigger substantial insulin spikes. This is due to their high fructose content, which, similar to high-fructose corn syrup, can lead the body to store more fat and potentially contribute to weight gain and other health issues over time.
