Discussion of the Mediterranean diet has been popular in the media for years.  The results of a multi-center study of the diet, the PREDIMED, were recently published in the New England Journal of Medicine.  There were 7,447 participants studied between 2003 and 2011.  Three diet variations were studied.  Mediterranean diet supplemented with olive oil,  Mediterranean diet supplemented with tree nuts (almonds, walnuts, and hazelnuts), and a low fat diet.  After five years the two Mediterranean diets showed a highly significant 30% reduction in the risk of suffering a cardiovascular death, a myocardial infarction or a stroke compared to the low fat diet.  This study runs directly contrary to the commonly held belief that low fat diets are better to protect the cardiovascular system.  It does suggest that the type of fats are important.

The Gallup Wellbeing Survey is an ongoing project tracking the health and wellbeing of Americans over time.  Part of what they track is self reported obesity, diabetes, and hypertension.  In summary, they are tracking metabolic syndrome.  It is very predictive for cardiovascular disease among other disease consequences.  The states with the highest rates of obesity were West Virginia and Mississippi with 33.5% and 32.2% respectively.  The lowest obesity rates were in Colorado and Massachusetts with 18.7% and 21.5% respectively.  The average rate is 26.2% for the US.  This is all self reported.  In general, the same high obesity states also had high rates of diabetes and hypertension.  Keep in mind that obesity, when self reported, is significantly underestimated.  

Obesity now surpasses smoking and alcohol abuse as a major health problem.  We are getting fatter and suffering the associated health consequences.
