This just may be the case if we look to a tiny Greek island with some impressive longevity statistics for guidance. A recent article on NPR detailed a tiny Greek island called Icaria where about 1 out of every 3 people live to the age of 90. They also seem to have much lower rates of cancer, heart disease and dementia.
It appears the people of Icaria are far from sedentary, walking daily to and from church or friends’ houses. Their diet seems to be more or less typical of the Mediterranean diet, in that they have high intakes of olive oil, fruits and vegetables. It also includes high amount of specific foods such as potatoes, goat milk, honey, and beans. They do not have as high a fish consumption as is usually found in the Mediterranean diet. But, they do have access to over 150 varieties of greens local to Greece and the authors state that these greens have ten times the antioxidants that red wine does.
What set this longevity hot spot apart from other areas of the world was their habit of drinking herbal tea at every meal. Apparently the teas that they drink are composed of diuretics. Diuretics work by flushing excess water and sodium from the body, thus lowering blood pressure. The authors felt this might be the mechanism behind the lower rates of heart disease.
