Agave NectarSweetener
Agave nectar is ~70–90% fructose by composition (vs sucrose's 50% and high-fructose corn syrup's 55%). Low glycemic index is a fructose artifact — fructose bypasses insulin-mediated metabolism and is preferentially shuttled to hepatic de novo lipogenesis. Chronic high-fructose intake is associated with hepatic steatosis, insulin resistance, and adverse lipid changes (Stanhope 2009 RCT). The 'natural' / 'healthier than sugar' marketing positioning contradicts the metabolic profile. Per brand voice: this is a clearer case than most of marketing-vs-science divergence.

Composition is proprietary and not disclosed — 'Natural Flavors' can include several hundred different compounds depending on the target flavor profile, including hexane-extracted constituents and proprietary carrier solvents.
