Eat the Rainbow: How Eating a Diverse Range of Colorful, Whole Foods Impacts Your Health
Updated: Jan 2
Have you ever heard the term 'Eat the Rainbow'? I love this concept because it reminds you of how important it really is to eat a diverse and colorful range of fruits and vegetables in order to maintain optimal levels of health. You get the most nutritional benefits from foods that are whole, vibrant and alive. And, the nutritional benefits that you get by eating those foods allows you to benefit in the form of abundant energy, optimal health and longevity.
What gives fruits and vegetables their colors?
Phytonutrients are biologically active compounds that are responsible for the way a food looks, smells and tastes. They are connected with a food's nutritional value and have a major impact on all of the body's systems helping to promote health and prevent disease. They are the chemicals that are essential to the body's nourishment.
Think of phytonutrients as nature's pharmacy. Foods with phytonutrients have antioxidant properties that help fight free radical damage caused by toxins and stress that can damage cells and tissues. They can help decrease the risk of cancer, diabetes, dementia and heart disease.
The pigments found in fruits and vegetables have been categorized into 4 groups of phytonutrients: Anthocyanins, Betalains, Carotenoids, and Chlorphylls. Check out the amazing benefits of each of these groups and learn how you can get more of these amazing nutrients in your diet.

Eat the Rainbow!
It is so important for the health of your body and diversity within your gut microbiome to eat a wide variety of foods in all different colors every day. Try to think of many different ways that you can eat all colors of the rainbow.
Here is an example of how you can include a variety of fresh, whole-foods in all colors in one day:
Breakfast: Smoothie with banana, spinach and blueberries (carotenoids, chlorphyll, anthocyanin)
Lunch: Black bean burgers topped with arugula and tomato with a side of beets (anthocyanin, chlorphyll, carotenoids, betalain)
Afternoon Snack: Grapefruit with a cup of cottage cheese (carotenoids, healthy fat)
Dinner: Baked eggplant over quinoa and diced orange bell pepper (anthocyanins, carotenoids, complete protein)
Tips to increase your intake of phytonutrients:
Try a new fruit or vegetable every week. Go to your farmer's market or the organic produce section in your supermarket and pick something out that you have never tried before. Look up a recipe or the best way to eat it and experiment with your new find.
Spice up your food. Herbs and spices are a great source of phytonutrients.
Double your typical serving of vegetables.
Eat a salad a day with different, fresh ingredients as much as possible.
Add vegetables to your favorite entrees.
Start the day off right. Add fruit to your oatmeal and veggies to your eggs.
Phytonutrients are not stored in the body so it is best to eat foods that are rich in them regularly.
Take some time to examine your eating patterns and plan your meals ahead when focusing on trying new foods and recipes. By choosing a rainbow of fruits and vegetables, you are making sure that you are getting a variety of these very important phytonutrients and providing yourself with optimal nutrition for a healthy, energized and vibrant future.
