Research shows that the Mediterranean diet is more effective than low-fat diets in lowering participants’ blood pressure, cholesterol levels, and blood sugar levels. The Mediterranean diet is characterized by high intake of fruits, vegetables, legumes, cereals, fish, and unsaturated fatty acids (mostly olive oil); low intake of saturated fats, meat and poultry; low to moderately high intake of dairy products (mostly cheese or yogurt); and a regular but moderate intake of alcohol (primarily wine) with meals. It has also been shown to reduce the risk of Alzheimer’s Disease.
