Eat the Rainbow for Disease Prevention

Have you ever heard that carrots are good for your eyes? What is it about this crunchy vegetable that may help to protect vision?

Fruits and vegetables have a variety of health benefits for health and wellness. In addition to being low in calories and good sources of dietary fiber, vitamins, minerals, and water... the colors of fruits and vegetables also contain functional compounds that may help to prevent chronic diseases. These disease-preventing compounds, called "phytonutrients" or "phytochemicals", are found in the pigments of fruits and vegetables. They are the compounds that also give fruits and vegetables their signature colors. The orange color in carrots is beneficial for protecting vision!

Each color or pigment found in fruits and vegetables provides diverse disease-fighting properties as listed below. By eating the rainbow with fruits and vegetables, you can vary your colors and phytonutrients consumed to prevent a variety of diseases.

Increase your daily intake of fruits and vegetables from each sub-group below with a variety of fresh, frozen, canned, dried, and dehydrated fruits and vegetables. Canned fruits and vegetables can be made healthier by draining and rinsing them and/or choosing versions without added salt or sugar. How could you get more of these colors on your plate this week for preventative health?
