I like the whole food based diet; essentially buying fresh items simple ingredients. Stick to the meat and produce isles, maybe go to the butchers or bakery for local meat and bread, and a greengrocers for local veg. Make things like sauces from scratch. I enjoy cooking which helps. I believe that no matter what Scientists decide are good/bad for that particular year I'm going to be okay because it's simple, fresh, and rarely processed.
