Veggie burgers aren’t really as healthy as you may think them to be. Widely popular in India, veggie burgers (you won’t get beef burgers even in McDonald’s in India) include soy which is made of hexane. Hexane is an air pollutant which is a by-product of gasoline refining. This hexane isn’t really a good thing. An Apple factory worker died in 2010 because of hexane poisoning while he was using that substance to clean touchscreens of Apple devices.
