Ground beef patties and carbonated drinks are no good for health, that I'd readily agree. However for Mc, I can't really fault their buns, fries and fillets. How else do you cook these stuffs? Fry them of course. Nobody's asking you drink the oil too. You can boil, steam or bake potatoes too, but they'd be still the same starchy stuff. Having a little residual oil from cooking or well, frying, can't kill anybody unless that body already have a chronic problem to begin with. Everybody uses cooking oil to, well, cook!
