One indicator of intelligence is your level of dependency to instant self-gratification, yeah junkfood seems to taste good, though you feel like crap afterwards. Healthy food tastes great and makes you feel that way afterwards too.
When it comes to eating healthy most people think of dull, boring food that's green in color. In reality, most of the world's healthiest foods not only taste great, they also come in a vast array of vibrant colors. Many require little, if any preparation, yet provide you with the energy and stamina to get through the day. They are the ultimate fast food!
