If there is one recurring ‘theme’ for my nutrition column each year, it’s my ‘Back to School’ piece in August.  Just about every year at this time, I try to impart some helpful hints for busy parents getting ready to send their kids to school.  This year, in honor of my ‘back to basics’ series inspired by the book Lessons in Chemistry, I’ll address childrens’ nutritional needs and how to meet them with common, packable foods.
