Think about the colors of the rainbow when buying fruits and vegetables. Buy as many different colors as you can. The more colors, the healthier you'll be eating.
When I go to the grocery store, I think of the colors of the rainbow. Roy G Biv was taught by my Home Ec teacher to remember the rainbow R-red, o-orange, y-yellow, G-green, B-blue, i-indigo and violet. Fruit and vegetables are similar. Get as many as possible.
