The Mediterranean diet is everywhere these days. In fact, according to the U.S. News & World Report, this is the seventh year in a row that the MedDiet was awarded the number one slot for "Best Diets Overall"—and for good reason. If you're game to see what all the hype is about, we have you covered with 10 of the best Mediterranean diet foods to buy at Costco so you can add them to your shopping list pronto.
