What are phytonutrients, and why "eat the rainbow"?

The pigments that give fruit and vegetables their bright colours — as well as herbs, spices and whole grains — are naturally occurring plant compounds called phytonutrients.

How much per day

  • Eat a balanced diet with at least 5 servings of colourful fruit and vegetables a day
  • The guide states this helps you get the nutrients you need, along with phytonutrients from your food

Remember: "eat the rainbow"

  • Each fruit and vegetable has its own pigments and phytonutrients
  • So eat many kinds of fruit and vegetables, in good amounts and in many colours

An idea from the guide

  • Combine several fruits, such as red apple, blueberries, grapes and orange
  • Toss them together in a vegetable or fruit salad
