In your latest WDDTY (vol 14 no 10), mention is made on page 7 of the Mediterranean diet. However, oregano is not included.
Studies by scientists at the US Department of Agriculture examined the antioxidant activity of different herbs and discovered that oregano was particularly high in antioxidants. They linked that with the lower rates of heart disease in Italy and Greece where this herb is widely used. Could it be that it is this herb rather than other ingredients of the Mediterranean diet which is instrumental? - Hans Lobstein, Brighton
