I remember once in junior high school, on a Friday, my mom came home from work and said to my brother and I, 'You know, between us, we have only 27 cents, but we have food in the refrigerator, we have our little garden out back, and we're happy, so we are rich.'

Whole foods like grains and beans release their sugar very, very slowly because of the fiber in them, and they don't give you a sugar rush. They feed your cells as needed, and as a result, you have loads of stable energy that powers you through the day.
