A Mediterranean-style food regimen, together with diminished caloric consumption, reasonable bodily exercise, {and professional} help for weight reduction, could reduce the chance of kind 2 diabetes (T2D) by 31%, in accordance with a brand new examine co-authored by researchers at Harvard T.H. Chan Faculty of Public Well being.
The examine was printed on August 25, 2025, within the Annals of Inner Medication.

Prior analysis has linked the Mediterranean food regimen — which emphasizes excessive consumption of fruits, greens, entire grains, and wholesome fat, reasonable consumption of dairy and lean proteins, and little to no consumption of crimson meat — to higher well being outcomes, together with lowered threat of T2D by improved insulin sensitivity and diminished irritation.

Individuals ranged from age 55 to 75, have been obese or overweight, and had metabolic syndrome, however have been freed from T2D at baseline.
