Last January, as one does, I pledged to eat better. Not one to phone it in, I adopted a meal plan with almost every vice crossed off the list. I blame Instagram, which was where I first spied the hashtag #Whole30, along with hundreds of iPhone-perfect images of delicious-looking food. If I ate nothing but whole, unprocessed foods for 30 days, the Whole30 program promised, I would have less bloating, fewer cravings, better sleep and more energy.
