​A challenge to plant-based meat alternatives

Clamoring to sell a plant-based burger than can pass for meat? There may be good reason to be a late adopter. Amid the rise in demand for plant-based proteins, a number of industry experts have questioned the more processed options available. (Case in point: The Impossible Burger has been criticized for its inclusion of the ingredient heme, which Food Dive describes as an iron-containing molecule made by fermenting genetically modified yeast.) Further, an article published recently in the Journal of the American Medical Association by doctors, nutritionists and public health specialists advised that further research was needed to determine if plant-based meat alternatives designed to mimic the real thing were in fact as healthy and beneficial to the environment as they claim to be.
