US News and World Report ranks fad and other diets annually. And every year for the past five years running, the Mediterranean diet came out on top.

The Mediterranean Diet isn’t a great diet compared with the truly healthiest diet in history, the Spartan Diet, simply because it’s vague about ingredient quality. But, like the Spartan Diet, it calls for olive oil and an emphasis on plant foods, it will always be healthier than whatever fad diets the nutrition industry comes up with.

The Spartan Diet is technically compatible with the Mediterranean Diet, but it differs in the Spartan Diet’s much higher standards for food types and food quality, cooking and baking methods, stronger emphasis on fermented foods and other details.
