Just 15 years ago, vegans were a rarity and it was virtually impossible to find vegan processed foods in supermarkets (at least foods which were labeled as such). Now, the ranks of vegans are growing. Depending on which poll you go by, 0.5% to 2.5% of the US population is vegan. So, it is no surprise that big business is stepping in to profit from the growing vegetarian demographic.
