Short-term High Dietary Fructose Intake had No Effects on Insulin Sensitivity and Secretion or Glucose and Lipid Metabolism in Healthy, Obese Adolescents

Randomized Controlled Trial

Human

2008 Mar

The study looked at what happens when obese teens eat more fructose for a week without changing their total calories, and found no negative effects on blood sugar or fat levels—just like the claim says.
