In recent years, the news has constantly covered the health benefits of the Mediterranean diet, a diet characterized by meals that use lots of fruits, vegetables, whole grains and healthy fats like olive oil. The Mediterranean diet is back in the news after a recent study found that it has the potential to delay the onset of Alzheimer’s disease. The study involved two groups of 70 participants. Half highly adhered to the Mediterranean diet for three years and the other participants adhered to a lower extent. After three years, the high adherers presented with fewer Alzheimer’s biomarkers. The researchers estimated that these changes would translate into a delay in Alzheimer’s onset by 1.5 to 3.5 years. These findings could indicate that a large part of Alzheimer’s development is diet-related. Since diet is largely in an individual’s control, we may be able to curtail disease development and help individuals age in a healthy manner through the promotion of a healthful diet.
