“Vegetables and fruits are an important part of a healthy diet, and variety is as important as quantity. No single fruit or vegetable provides all of the nutrients you need to be healthy. Eat plenty every day. At least nine different families of fruits and vegetables exist, each with potentially hundreds of different plant compounds that are beneficial to health. Eat a variety of types and colors of produce in order to give your body the mix of nutrients it needs. This not only ensures a greater diversity of beneficial plant chemicals but also creates eye-appealing meals.”
