We’ve all seen the commercials: Athletic shoes that tone your butt, junk food that’s billed as “whole grain” or “contains more calcium than a glass of milk,” diet systems that promise you an athlete’s body by just popping a few pills. The list goes on and on. And people keep snapping up these and other products looking for a quick fix. If you had just landed on Earth from another planet and all you had to go on was advertising, you’d think that we were the fittest, healthiest people in the Universe. But as we all know, we may very well be the unhealthiest and unfitteset people in the Universe.
