University of California researchers link fructose to obesity via fat absorption

Researchers from the University of California, Irvine, have identified a new mechanism linking fructose consumption to obesity. A study published in Science Advances suggests that fructose affects how the body absorbs fat, specifically involving the small intestine and its villi.

While fructose is naturally occurring in fruits and vegetables, the study focuses on the impact of high-fructose corn syrup, a common additive in processed foods. The findings indicate that the sugar may trigger a metabolic cascade in the small intestine that promotes weight gain, moving beyond the simple understanding of caloric intake.
