This Common Fat Could Be Fueling Type 2 Diabetes, Researchers Warn

University of Barcelona researchers found palmitic acid and oleic acid have opposite effects on inflammation, insulin action, and cell health.

Palmitic acid was linked to harmful metabolic changes and higher insulin resistance risk, while oleic acid showed protective effects.

The review suggests fat quality, not just fat quantity, may matter for type 2 diabetes prevention and treatment.

Findings align with the potential benefits of Mediterranean, olive-oil-rich diets for metabolic health.
