Recently published in the New England Journal of Medicine, the results were so strongly in favor of the Mediterranean diet that they actually stopped the trial early!The study involved both men (ages 55 to 80) and women (ages 60 to 80) who had either diabetes or three risk factors for heart disease. These typical heart disease risk factors included smoking, elevated blood pressure, elevated bad cholesterol (LDL) or low good cholesterol (HDL), being overweight or obese (BMI greater than 30) or a positive family history of early heart disease.QUIZ: How Healthy Is Your Body?The authors divided the participants randomly into three groups: Mediterranean diet + extra olive oil, Mediterranean diet + extra nuts and a control group (regular diet).

Maybe some olives, tomatoes, mozzarella cheese. Limit the processed foods, limit the extra sugar—and plan for an extended retirement in the lap of Mediterranean health and luxury.
