Mo’ meat, mo’ problems? That’s the premise of documentaries like Forks Over Knives, which explore the theory that animal-based and processed foods lead to degenerative disease and other health issues. The popularity of such films—coupled with a mass movement toward healthier eating—points to an overall trend: plant-based diets are hot. A 2012 Vegetarian Resource Group survey found that 7.3 million Americans are vegetarian, while 22.8 million others follow a vegetarian-inclined diet.
