Agave nectar is a sweetener that is often marketed as healthy. However, agave nectar is not as healthy as some people think. It is a highly refined sweetener that is extremely high in fructose.
High amounts of fructose from added sweeteners (not whole fruit) can be absolutely disastrous for health.
The truth is, agave is even higher in fructose than other sugars.
Whereas table sugar contains 50% fructose, and high fructose corn syrup around 55%, agave nectar is 85% fructose.
Alternatives: Stevia and erythritol are healthy, natural and calorie free.
