To obtain the full health benefits of daily juicing, you should juice a wide variety of fruits and vegetables.  Luckily, nature helps us with a color code to pick what plants to use when juicing.  The different colors of fruits and vegetables provide a framework to give us good variety for maximum benefit.  Nature helps us by color coding our plant based nutrition sources.  Rainbow juicing allows you to use the color coding to your advantage when making your juice recipe.

The different color categories are  yellow/orange, green, red, white/tan and blue/purple.  The pigments arise from different micronutrients contained in the fruit or vegetable.   Here's a breakdown of each group showing what fruits and veggies are included, what beneficial compound causes the pigment, what are some other nutrients commonly found in each category and what are the health benefits.
