I found this article Agave Nectar: Good or Bad? by Kristen Michaelis from Food Renegade. She goes into great detail about why we should avoid agave nectar, a rather popular sweetener alternative. It turns out it's not a natural sweetener and isn't so different then high-fructose corn syrup. She also delves a little into why we should avoid fructose. Take a minute or two to read it and check out the website. There are a lot of great articles to read.
