31 Jul 2018 --- Impossible Foods has received a no-questions letter from the US Food and Drug Administration (FDA), validating the unanimous conclusion of food-safety experts that its key ingredient – “heme” – is safe to eat. Impossible Foods makes meat directly from plants and the company uses science and technology to create wholesome, nutritious food, restore natural ecosystems and feed a growing population sustainably, thus with a much smaller environmental footprint than meat from animals.
