Recent Progress on Fructose Metabolism—Chrebp, Fructolysis, and Polyol Pathway

Narrative Review

Human

2023 Apr 5

The study shows that the body can make its own fructose from sugar (glucose), and this process might harm the liver, even without eating fructose. This supports the idea that too much sugar in the blood can cause problems through this internal fructose production.

Similar Assertions

Eating fructose (like in sugary drinks) might be worse for your body than eating glucose (like in bread), because it can lead to more harmful fat buildup, insulin problems, and higher uric acid — all of which could increase your risk of heart disease.
