“I don’t chase rainbows. I eat them.”
~ Anonymous

Nature’s Bounty

Isn’t that picture gorgeous? I can’t look at it without smiling. There’s a reason junk food companies add bright food coloring to fake food. Our eyes and bodies are drawn to the colors because in nature, they signal deep nutrition inside. In fact, each color contains a different type of nutrient for the body. That’s why it’s recommended we “eat the rainbow” every day.

If you’re following the paleo autoimmune protocol, some of the brightly colored vegetables are out during the elimination phase (nightshades, I’m looking at you!) But there are many AIP options still available, and I’ve included an abundance of choices below.

Fruits and vegetables are kind of like clothes when you’re doing laundry. They often contain more than one color, so when it comes to putting them in a category, it’s tricky! Similarly, their health benefits overlap also. For example, red isn’t the only color food that can help reduce inflammation, and blue isn’t the only color to benefit the brain. The idea behind “eat the rainbow” is to inspire us to expand the variety of fruits and vegetables we eat, because while some nutrition overlaps, every food also contains something unique. Don’t get obsessed with doing this perfectly. Instead, have fun with this list! Use it to bring more beauty and flavor to your plate, as well as nutrition to your body.

  1. Wow, thanks Eileen for these great lists! It is so easy to get in a ‘food rut’ and eat the same foods on a regular basis. Your article and these lists are a great reminder of the many food options available, and the many reasons for eating a varied diet. You’ve inspired me to seek out some new cooking ingredients.
