The Study
The Dose-Response Effects of Consuming High Fructose Corn Syrup-Sweetened Beverages on Hepatic Lipid Content and Insulin Sensitivity in Young Adults
This study shows that when young adults drink more sugary drinks with HFCS, their liver fat goes up and their body handles sugar worse — and the more they drink, the bigger the effect. But because people weren’t randomly assigned to drink different amounts, we can’t say for sure that the HFCS caused these changes — other factors might be involved.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
Drinking soda-like drinks with lots of corn syrup sugar every day for just two weeks made young people's livers store more fat and their bodies less able to handle sugar—even if they were healthy before.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes, this matters—these changes are early signs of diabetes and fatty liver disease, even in healthy young people.
- 2At 25% of daily calories from sugary drinks: liver fat went up, insulin sensitivity went down, and blood sugar and lactate spikes after meals got worse.
- 3More sugar = worse results.
