I am not sure if its a justifiable comparison, typically you don't end up with a food costs in the hundres of thousands or millions in the blink of second. It's not like you all of a sudden get a bill from Mickey D for someone showing a truckload of hamburgers down your throat.

I am not completely sure where you want to go with this argument. But as a Scandinavian I am very much comfortable with the state ensuring my access to health care, knowing I do not ever have to ever have to think about medical costs, health insurance or access to one of the better health care systems in the world for me or my family. We could very much bear the costs of having private health insurance, but its just one less (big) worry...

I do think that production of food is very much a state matter - and unless you knew taxes in the US today go towards ensuring safe and predictable production of food through i.e. agricultural subsidies. I would expect the state to ensure that the country have a viable and thorough plan to ensure food supplies.

Food production is heavily subsidized in the US because a free market would wipe out producers the second market conditions impact their profitability.
