This is so true. I'm a pretty optimistic person normally but when I really started to think about food in a holistic way, things changed. I learned what foods made me feel good, or frumpy and down right tired. Its take more than one meal but try eating clean eating for 3 days and see how your mood shifts. Do it for a week and notice your energy lift. Do it for a month and see physical changes in your hair, face, and skin (and you might lose a clothing size too.). Try it for a life time and NO ONE can kick you to the curb!
