1. It promotes the misguided notion that saturated fats are bad for you.

Like the U.S. food pyramid, the Mediterranean diet vilifies saturated fats. Things like red meats and eggs, according to the diet, should be eaten sparingly. Saturated fats, however, have been wrongly blamed for the epidemics of heart disease and obesity. In reality, these healthy animal fats are necessary and very good for you.

2. It encourages eating many grains.

Bread, pasta, rice, potatoes and other grains are emphasized in the Mediterranean diet. Never mind that these are the exact items (along with vegetable oils and sugars) that have significantly contributed to heart disease, diabetes and obesity spiraling out of control in the United States. A small portion of people, perhaps one-third, can thrive on a diet like this one that encourages whole grains. But what about the rest of us? 

You can read my other article on insulin to find out if you are someone that needs to avoid many or most grains.

3. One diet could never be right for everyone.

You have an individual nutritional type that dictates which foods are healthy for you. Those foods may or may not be the same ones that are healthy for your spouse, your neighbor or your best friend. So while a carb nutritional type may do very well on the Mediterranean diet, a protein type would feel lousy because there simply isn’t enough red meat and fat to sustain them.
