Food is a right not a want so why does it cost so much

We pay hundreds of dollars every month to feed families of as small as two and three people, but why? Supply and demand are not causing this issue. In fact more food is thrown away by grocery stores than what is bought and consumed because of how much it costs. Everyone fairly well knows food is something we need in order to gain the energy necessary for basic life functions, so why are we paying so much for it? We are saying to every man woman and child you can only eat healthy if you can afford it. This is wrong! Our tax dollars go to several things we did not ak for them to go to, so let's make a real change. I propose our tax dollars go into a program that makes it to where nobody has to pay for necessary foods. Sure the candies and sodas should cost something we have to earn, but if it is something we need like meat, fruit, vegetables and grains we should have the right to at least a set amount of that food instead of watching it get thrown away by the thousands of pounds every year.
