USA News has re-ranked the world's best diets according to their panel of nutritionists, and the Mediterranean Diet comes in at #1 overall!
Things I like about it from what I've read is that it's really more about diet adjustments rather than sticking to any strict regimes. That, and you're encouraged to drink a glass (but only one) of red wine with a meal.
There's a guide here which comes with a free printable shopping list (attached) and a bit more information.
Hardest part for me will be trying to eat more fish and seafood. It's something I usually do and am not the biggest fan of the stuff. Plus, it can be quite pricey.
Thoughts?
