You have an apple tree that produces 3 bushels of apples a year. At a normal rate of consumption you can eat 1 bushel before the apples start rotting. By the time you've consummed half the second bushel the rest are inedible. However if you dry them, can them, make them into cider/apple sauce/whatever, then you can consume all three bushels, albeit at a lower nutritional value compared to fresh, ripe apples. Processing foods reduces the nutritional value and the taste /demand, thus lowering the price point. It does allow for more efficient use of the produce and reduces wastage. Thus I can buy a bag of potato chips cheaper than I can buy a potato.
You can buy a bag of potato chips because the chip industry knows you cant eat just one, since they are covered in cooking oils and seasonings. Go ahead and cover a raw potato in the same and tell me it tastes better. It wont because that potato requires work and preparation to taste good. Were lazy as humans. The less we have to do for ourselves the better we think were doing for ourselves. In my family, we try to keep it as real as possible. We make a lot of our own foods from scratch. We make a lot of the ingredients to make the food from scratch too. Less waste that way which lowers our food bill. I do realize not everybody wants to or can do the same, but you can for sure strive to take care of yourself and not depend on the chemical companies to make our food.
Water is basically harmless but lots of people still drown, and you can die from drinking too much. At the kind of levels anybody consumes MSG at there's zero evidence to show it's harmful.
I think you mean lucky charms and cinnamon toast crunch. Those have Trisodium Phosphate. It's good stuff.
I saw a guy slightly bigger than that, climbing up the side of a cabover in Panama City one time. All I could think about was the dent in the asphalt the guy was going to make if that grab bar broke off the side.
