When my girls were little and first learning about their food we used to talk about eating a rainbow of colors every day.

I had this great book, I Can Eat A Rainbow” by Annabel Karmel, that walked through each color of the rainbow, and in fun food-based animal images talked about the fruits & veggies that fit into each color group.

I even took this book to their preschool & kindergarten and gave little rainbow lessons to the children about how to choose healthy foods.

It was incredibly effective! My girls loved checking off their list of colors each day and would help me make decisions about what their snack or veggies at dinner would be based on what colors were left for the day.

We even made Rainbow Fruit Kabobs for birthday celebrations and gatherings.

It occurred to me that there’s no reason this method shouldn’t also work for grown-ups. Because the truth is we ALL need to be eating a rainbow of colors every day.

Plants are full of good-for-you fiber, vitamins, and minerals. But what’s even more exciting about plants are the chemicals in them that create pigment…or give the plant its color!

It is these chemicals that are being shown in research studies to reduce inflammation, kill cancer cells, and prevent diseases such as Diabetes, Heart Disease, Parkinson’s, Alzheimer’s, and more.

The Power of Color

These colorful plant chemicals are also known as phytonutrients and make up all the different nutrients in plants that don’t fall into the category of vitamin or mineral.

Plants produce these nutrients to protect themselves against environmental threats like pests, pollution, harsh growing conditions, or disease.

This is actually why organic fruits & veggies have been shown to have higher levels of phytonutrients in them. When a plant has to defend itself against pathogens (as is the case with organic food) this increases its production of chemicals to help fight off the disease or pest, which in turn increases its level of beneficial phytonutrients. (study)

And although most of us are familiar with the different vitamins and minerals we should be including in our diet, the same is not true for phytonutrients.

According to a 2009 phytonutrients report (from the National Health and Nutrition Examination Surveys), 8 out of 10 people in the US are falling short in virtually every color category of phytonutrients.

  • 69% are falling short in green phytonutrients
  • 78% are falling short in red phytonutrients
  • 86% are falling short in white phytonutrients
  • 88% are falling short in purple and blue phytonutrients
  • 79% are falling short in yellow and orange phytonutrients

Is this true for you?!

With just a little awareness & intentional meal planning we can change that.

Let’s take a look at each of the six color groups, why they are important, which foods fall into each category, and ideas to help you get more of those colors in your diet every day.

My Favorite Rainbow Recipes

It doesn’t have to be hard to get all your colors in each day. There are many yummy ways where you can get most, if not all, of your colors in just one meal. Here are some of my favorites.

A Checklist To Reach Your Goal

If digestion begins with your eyes, then make your plate as colorful as possible. Not only will this make your food more beautiful and appetizing, it will also improve digestion and your health!

The GOAL = 1+ foods from every color every day

This means at least 6 different colors plus 8-10 servings of fruits & veggies every day!

As with anything, it’s helpful to have a sense of what you’re currently doing.

Keep a journal for a few days and check off how many colors you’re typically getting.

  • Is there at least 1 food in each color group every day?
  • Are there some colors that you’re never getting?

Start with the ones you’re never, or rarely, getting. Refer to the examples above and start planning in ways you can eat more.

  • Can you add it to the meals you’re already doing?
  • Can you add it in as part of a snack or a dessert?
  • Can you try one of the Rainbow Recipes above?

Then move on to the colors you are getting in but not consistently.

  • Is there a way you could start bringing in that color every day?
  • How could you do more?

With just a bit of awareness, you’ll be surprised how easy it is to check off all of your colors each day. Your grocery cart will become more colorful. Your table and plate will become more colorful. You will be adding more beauty and variety to your meals while gaining the benefits from immune boosting, inflammation lowering, disease preventing phytonutrients!
