The medical bills skyrocket, the antibiotics breed stronger germs and the kids sit in front of video games eating junk. It amazes me that folks who would never dream of running their car engines on anything but good fuel will put junk fuel in their bodies and expect them to run in peak condition. Then the public schools got into the act with soda and candy machines and too many kids are so sugared up they cannot sit still for more than five minutes, never mind learn. I saw an ad for a new cereal, some kind of miniature cookies and the thought of putting that in a child's stomach first thing in the morning turned my stomach. Just imagine eating all that sugar from the sugar bowl and imagine what that is doing to the body.
Sugar hops a kid up, then they crash, neither a good way to help the brain intake data and learning.
When I was a girl, we camped out and the forest was a veritable supermarket. As the early settlers traveled across the plains, many of them starved to death and all while the Indians ate well, off the land. Another thing my family did each Spring was to pick the first dandelions of the season, when they were tiny and tender. They were thoroughly washed and made into a salad, with the dressing a bit on the vinegary side. This acidic combination worked well to help the body to adapt for the warmer temperatures also.
