I love rainbows. And not just because I am an astronomer, even though the colors of the spectrum are extremely important to astronomers. For me, the rainbow is more than a conveyor of information about the Universe. It is a source of beauty.
I do not see rainbows very often. Maybe one or two per year in recent memory. I remember a very beautiful rainbow I saw at the beginning of autumn this year as I was sitting in a restaurant eating dinner. I had a front row seat for seeing that spectacular display!
And hanging in my windows at home I have some glass ornaments, so occasionally there is a rainbow spectrum which sends a splash of color across my wall.
So with my love of rainbows, I was delighted to find that I could apply the rainbow to my eating habits. One of the principles put forth in the book Food As Medicine by Dr. Dharma Singh Khalsa is that I should EAT A RAINBOW EVERY DAY.
What does this mean? Well, nutrient dense foods are colorful foods. [I have been hearing that for several years -- from nutritionists, from my chiropractor, from my acupuncturitst.] So, to eat a rainbow every day means to eat red, orange, yellow, green blue, and violet foods every day. And that means fruit and vegetables.
So now I shop for color. Tomatoes, raspberries. Carrots, oranges. Pineapple, squash. Lettuce, broccoli. Blueberries and more blueberries. Blackberries, plums. And I eat for color. I remember to eat more fruits and vegetables with this simple reminder to eat a spectrum of color every day. It's a fun, beautiful way to approach nutrition and health.
Of course I would much prefer to see a rainbow in the sky every day, but if I can't see one, then at least I can eat one!!!
