The Benefits of a Mediterranean Diet

    Over the decades, investigators have made a number of attempts to identify a diet that provides the most effective nutritional benefit, while promoting reductions in incidences of chronic diseases such as cardiovascular disease, diabetes, and certain neurological disorders. A recent meta-analysis indicates consuming a balanced diet comprised of vegetables, fruits, nuts, fish, dairy, and meat/poultry support a healthy lifestyle, and reduces the risk of cardiovascular mortality1, 2.  This type of diet also contains high levels of antioxidants reducing the presence of free radical oxygen species that can harm cells in the body. For this and other reasons, the Mediterranean diet is associated with reduced incidences for developing Parkinson’s and Alzheimer’s.

See chart below for the suggested components of the Mediterranean diet:

    Just to keep this post short, I will focus on the fat portion of the Mediterranean diet, which contains high levels of monounsaturated fat while having low amounts of saturated fat. That is a good thing, because not all fat is bad, our bodies need fat for lots of things; however, it’s harder for our bodies to breakdown saturated fats, so best to stick with mono or unsaturated fats. So, for all of you cooks out there, continue to use olive oil in your preparations. Also, extra-virgin and virgin olive oils, have high levels of those antioxidants I mentioned earlier. So, when you can pass on the butter, and stick to the olive oil!
