Eating a Twinkie, for example, might make your mind happy, but does it make your body happy? What about your soul? Is your soul calling for the Twinkie? Let's be real with ourselves.
True happy food makes us happy in all realms of our Selves. It nourishes our mind-body-spirit. If it doesn't feed one of those human elements, that can we honestly call it happy food? I think not.
I'd rather be happy.
