## Summary

This review pulls together evidence showing fructose does more than add calories. It triggers a chain reaction: uric acid buildup, mitochondrial stress, and fat storage signals that affect the liver, kidneys, pancreas, gut, heart, lungs, and brain. The damage traces back to how fructose is processed differently than glucose, depleting cellular energy and driving inflammation. Animal and human studies both point to fructose overload as a metabolic disruptor across nearly every organ system.

## Practical Takeaway

This review suggests limiting excess fructose intake may help protect multiple organs beyond the liver.
