Prevention and Control of Type 2 Diabetes by Mediterranean Diet: A Systematic Review
July - 30 - 2010
Adopting a Mediterranean diet may help prevent type 2 diabetes and may improve glycemic control and cardiovascular risk for those who already have diabetes, researchers have found. Investigators reviewed 17 studies that assessed a Mediterranean diet's effect on type 2 diabetes. Two large prospective studies report an 83 percent and 35 percent, respectively, lower risk of type 2 diabetes in healthy people or in post-infarct patients who had the highest adherence to a Mediterranean diet. Five randomized controlled trials have compared a Mediterranean diet with other common diets on glycemic control in type 2 diabetes patients. A Mediterranean diet showed greater improvement of fasting glucose and HbA1c levels, ranging from 7 to 40 mg/dl for fasting glucose, and from 0.1 to 0.6 percent for HbA1c. None of the trials reported that a Mediterranean diet led to worsening of glycemic control. Two controlled trials also demonstrated that post-infarct patients, including those with diabetes, saw cardiovascular benefits when adhering to a Mediterranean diet.
