IMHO the fact that living without food has been possible for some humans does not men that food is no the n.1 top priority to the rest of the world.
I was puzzled by reading that food is just waste and does not build anything in the human body. I do not believe this to be true.
Yes, junk food is just waste, and most people are overating, too. but good food seems to be the key to build healthy bodies.
Any breathairiaan out there to answr the question thoroughly?
