Four years ago, when I was something of a YouTube health celebrity, I was on top of the world and . . . the diet pyramid. I ate the cleanest, most nutritious diet on the planet or so I thought. A raw-food vegan diet . . . not only pure in its contents but also pure in its intention. With this type of diet, you eat straight from the earth, only as nature intended. I ate kale salad, raw nut butters, goji berries, raw chocolate, and dehydrated flax crackers. I drank green smoothies, green juice, wheatgrass, and hemp milk. I even tried a fruitarian diet . . . I thought about food from the moment I woke up until the second I fell asleep . . . I was an addict in search of the purest dope raw, vegan, organic food . . . I was headed down a path of self-destruction.
