The Rainbow Diet: How Eating Colorful Foods Boosts Your Health

The phrase “eating the rainbow” refers to consuming a variety of fruits and vegetables of different colors. We’ve developed palates that appreciate a succulent mango or a peppery radish, and we understand that these foods are our primary source of vitamins and minerals, and ultimately, energy. For those who are extremely short on time or travel a lot, we recommend supplementing with a good Greens powder. But when you look at your diet, are you getting enough variety?

What is the Rainbow Diet & Why is it Important?

The rainbow diet is a colorful and delicious approach to eating that emphasizes the importance of consuming fruits and vegetables in every color of the rainbow. Each color represents different phytonutrients and antioxidants that offer unique health benefits, from boosting heart health to improving brain function.

Eating a wide variety can help protect us from ailments and illnesses and keep us healthy in the long term. For example, the lycopene that makes watermelon appear red may also help prevent prostate and breast cancers. Similarly, the beta-carotene that gives carrots and sweet potatoes their orange hue helps keep our bones strong and our eyes healthy while boosting our immune systems.

The Health Benefits of Eating the Rainbow

Knowing how each color helps you look and feel your best is a great way to stay motivated to fill your plate with a variety of fruits and vegetables every day. Here’s a look at how eating from the rainbow is the best way to nourish our bodies with all of the nutrients we need:

Benefits of Red Foods

Eating the rainbow includes red fruits and vegetables. This means beets, pomegranates, and tomatoes, which protect the body from free radicals with antioxidants. Beets get their color from benatin, a phytochemical that’s thought to boost our immune systems. The juicy red jewels in a pomegranate are packed polyphenols, which protect the body from oxidative stress as well as cancers, coronary heart disease, and inflammation. If you’re taking part in our Clean Program cleanse, you can enjoy dried chile peppers in small amounts, which stimulate brain chemicals that curb hunger, and off the program you can add in tomatoes, which like watermelon, contain the cancer-fighting antioxidant lycopene.

Benefits of Orange Foods

Mangoes, sweet potatoes, and carrots all get their orange huge from beta-carotene, a carotenoid that supports healthy hair, skin, and eyesight. The inner flesh of mangoes is a brilliant yellowish orange, bursting with over 20 vitamins and minerals that help decrease our risk of colon cancer, improve our digestion, and strengthen our bones. In addition to preventing macular degeneration, the beta-carotene in sweet potatoes and carrots gives our skin a healthy glow by reducing damage caused by UV light, pollution, and other environmental hazards. Plus, some studies suggest that eating as little as one carrot a day may reduce wrinkles and other signs of aging.

Benefits of Yellow Foods

Yellow foods, including lemons and golden beets, are chock-full of beta-carotene, flavonoids, vitamin C, and zeaxanthin, all of which are important for keeping us healthy from our eyes to our internal organs. Lemons are a terrific digestive aid and have the unique ability to detoxify the body. We love drinking warm lemon water every morning to flush waste and toxins leftover from the digestive process. Similarly, golden beets are excellent at cleansing the body, specifically the kidneys.

Benefits of Green Foods

Most green foods, like kale, spinach, and broccoli, are considered superfoods because they’re so rich in antioxidants like carotenoids and flavonoids. These lush vegetables get their green pigment from chlorophyll, a powerful digestive aid that also assists with hormonal balance and detoxification. In addition to vitamins A, K, C, iron, and calcium, leafy greens are an excellent source of folate, which can reduce our risk of cardiovascular disease and memory loss. As if green foods weren’t impressive enough, they also contain phytonutrients that boost our immune systems and help protect us against cellular damage.

Benefits of Blue Foods

Researchers believe that anthocyanins, the compounds responsible for giving blue and purple foods their deep, rich color, reduce our risk for high blood pressure and cholesterol and harness the same UTI-fighting power as cranberries. It’s also proven that the darker the food, the higher the concentration of antioxidants. Thus, blue and purple foods like blackberries, figs, and purple cauliflower have amazing healing properties – and grains aren’t excluded. Black rice has been found to reduce liver damage incurred by excessive alcohol intake.

How the Rainbow Diet Improves Gut Health

Your gut health is crucial to your overall well-being, and the rainbow diet plays a key role in supporting a healthy gut. Eating a wide variety of colorful foods introduces diverse types of fiber and nutrients into your diet, which can help to reset your gut health.

Gut Microbiome Diversity

A diverse microbiome is key to a strong immune system, better digestion, and even mental health. By eating a colorful array of foods, you’re nourishing the beneficial bacteria in your gut, creating a more balanced and resilient system.

Fiber and Digestion

Each color of our fruits and vegetables provides different types of fiber, which aid digestion and help maintain regular bowel movements. The fiber-rich nature of these foods supports a healthy gut environment, reducing inflammation and improving digestive health.

Eat the Rainbow for a Healthier You

Eating the rainbow has numerous benefits to our health and wellbeing. From giving our skin a healthy and radiant glow, to protecting us from cancer, to detoxifying the liver, filling your plate with a variety of beautiful fruits and vegetables is the best way to ensure you’re getting the full spectrum of nutrients you need to thrive.
