Agave nectar is a highly processed liquid sweetener made from the agave plant's starch, but it's not a natural product. You're getting a concentrated dose of fructose, which can wreak havoc on your health. This isn't a sweetener, it's a sugar substitute designed to hook you.
Why trash
Marketed as 'natural' but processed like high fructose corn syrup — up to 90% fructose.
Try instead
Honey, maple syrup, or coconut sugar
