This could take a dent or if sugar companies too. As such there weird probably be sanctions against you based on politicians and lawyers  paid by sugar companies, but it is a nice idea of a charity for the (ultimate) same of public health.  Just by potatoes and vegetable oil en masse and  give out free chips, with the option of free donuts. No one would need to pay money for those any more, and if it's large enough scale you could make junk food business go out of business.  Ooooh, if only I had billions of dollars. I'd corner  the shit out of the potato market
