Eating a Mediterranean Diet Associated with Lower Risk of Developing Type 2 Diabetes

A recent review performed a meta-analysis on studies within the last year to determine if consuming a Mediterranean-style diet had any influence on type 2 diabetes or not.

The 17 studies included in the review varied in nature in terms of their experimental protocols: 1 was a clinical trial, 9 were prospective studies,

and 7 were cross-sectional studies. Comparing studies with different experimental designs can be somewhat problematic, but there are ways to compare on a more broad scale.

Primary finding:

  • Sticking to a Mediterranean diet led to a 23% decrease in the risk of developing type 2 diabetes.
    • Even when controlling for region, general health status, and several other potentially confounding factors, this decrease in risk of developing type 2 diabetes was still seen.

While not a be-all end-all “cure” for type 2 diabetes, according to this meta-analysis, eating and maintaining a Mediterranean-style diet could provide some nutritional benefit to those wishing to prevent development of the disease.
