You are what you eat is an old saying. It's no myth. Even though we can't see how the food we choose to eat effects our insides, we can feel it. Eating healthy makes you less tired, more alert, more confident, and even extends your life. By making good diet choices, you are overall much happier. Many times when eating something that is "junk" we feel guilty afterwards. Many people don't realize that even small substitutions can make their meal much healthier. Next time you pick up processed or fast food, think to yourself, do I want my body to be made up of this crap?
