Many agave nectar products contain up to 90 percent fructose, and high levels of blood fructose have adverse effects on health.Continue Reading
Long-term insulin resistance eventually impairs the body's ability to metabolize glucose, explains Jamerson. If untreated, insulin resistance combined with high blood sugar can cause prediabetes and then Type 2 diabetes.

However, agave nectar is not considered a healthy alternative to regular sugar by many health experts. As of 2015, not enough studies have been conducted to support the health benefit claims of agave nectar.

Due to its sweetness, it is possible to use a small amount of agave nectar for many recipes.Learn more about Side Effects
