The Claim
Fructose intake is associated with reduced expression of hepatic insulin receptor and IRS2, which impairs insulin signaling independently of weight gain or total caloric intake.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Eating too much fructose—like the sugar in soda and candy—might mess up how your liver responds to insulin, even if you don’t gain weight or eat more calories overall.
