PHILADELPHIA (CBS) – The Mediterranean diet is modeled after those who live on the Mediterranean.

People from this region are known for living long, healthy lives. The diet is rich in fruits, vegetables, olive oil, and fish. We know that it protects against conditions such as coronary artery disease, heart attack, high blood pressure, obesity, and even some forms of cancer.

Perhaps the most exciting news in recent years has come from Columbia University where it has been found that people who follow the diet have a lower risk of developing Alzheimer’s disease.

Those who followed the diet had a 68% reduction in developing Alzheimer’s. There will continue to be new studies but as we move on it is clear there are numerous reasons to favor this diet.
