Scientists Warn: Popular Sweetener Linked to Dangerous Metabolic Effects

A new review in Nature Metabolism says fructose may pose a distinct metabolic risk compared with glucose.

Researchers argue fructose can promote fat storage, lower cellular energy, and contribute to metabolic disorders.

Both dietary fructose and fructose produced inside the body were cited as possible drivers of obesity, insulin resistance, and metabolic syndrome.

The findings could shape future guidance on sugar intake and prevention strategies for diabetes and cardiovascular disease.
