Eat the Rainbow!

CenterLight Dietitian Kaitlyn Hempfling recently spoke on CenterLight’s Facebook page about how eating a variety of colorful foods can help us live healthier. In this blog post, she explains how vibrantly colored foods can add needed nutrition to our diet.


WHY IS EATING COLORFUL FOODS IMPORTANT?

Antioxidants give fruits and vegetables their color, and each color has its own nutritious benefits. The more vibrant the color is, the more antioxidants a fruit or a vegetable has.


Why can colorful foods help make us healthier?

It’s because antioxidants protect our cells from free radicals.

Free radicals are produced when your body breaks down food or in certain situations when you are exposed to smoke or radiation. They play a role in diseases such as heart disease and cancer.

Plant-based foods such as fruits, vegetables, herbs and spices, whole grains and nuts are the best sources of antioxidants. And since different antioxidants have different colors, it’s very important to eat the rainbow!

Remember that no one color is more beneficial than another, which is another reason why you should incorporate as many colors in your diet as you can. Also, in some foods such as apples, peaches and eggplants, the majority of the antioxidants are in the skin. I recommend to try to avoid peeling these items to get the most benefits.


Benefits of each color

Katherine D. McManus, MS, RD, LDN from Harvard Health also spoke about the benefits of each color of the rainbow in the foods we eat, such as:

Red

strawberries

Red fruits and vegetables are rich in lycopene, which can help protect against prostate cancer, heart disease, diabetes and lung disease. Examples of red foods include apples, strawberries, tomatoes, cherries, beets, red grapes, red onions, raspberries and watermelon.


Orange and Yellow Foods

corn

Orange and yellow foods are rich in beta carotene. Beta carotene is converted into vitamin A in your body, which helps to support healthy eyes, skin, teeth and bones.

Orange and yellow foods also help support inter-cellular communication, which is good because it can help prevent heart disease and some cancers.

Examples of orange and yellow foods include carrots, sweet potatoes, orange and yellow peppers, oranges, cantaloupe, corn, winter squash, pineapple, tangerine, mangoes and bananas.


Green

green foods

These foods are rich in chemicals that inhibit the action of cancer-causing compounds, called “carcinogens.” They also have vitamin K, which is essential for our blood health and bone health.

Examples of green foods include leafy greens such as spinach, kale, swiss chard, avocado, kiwi, green tea, green herbs, brussels sprouts, broccoli, asparagus and artichokes.


Blue and Purple Foods

These foods have something called anthocyanins, which are powerful antioxidants that have anti-aging properties. They help your memory, and can help lower high blood pressure.

You can find this in blueberries, blackberries, grapes, raisins, eggplant, plums, lavender, figs, prunes and purple cabbage.


White and Brown

White and brown foods have anti-tumor properties.

You can find this in onions, cauliflower, garlic, leeks, parsnips and mushrooms.


HOW to make your diet more colorful

  1. Try to have different colors in each meal that you eat. For example, if you’re having potatoes as your starch for lunch, try to add broccoli as a side.

  2. When you’re doing your grocery shopping, take a second to look at your cart and be mindful of the colors you see. If you find that you’re only buying one or two colors, think about where you can make substitutions. For example, if you always get a bag of potatoes, consider buying a bag of tri-colored potatoes instead. If you always buy apples and oranges when you shop, consider varying what fruits you get weekly—perhaps a banana this week and blueberries next time.

  3. Add fruits and vegetables to foods you already love to cook or prepare. For example, if you’re cooking pasta, consider adding spinach or other ingredients into the dish. This will not change the taste but will add nutrients to your diet.

  4. Make your own smoothies. A basic smoothie can consist of frozen fruits, low fat Greek yogurt or milk and water all blended together. You can great creative and add in different fruits, vegetables, nuts and seeds. You can even try to add foods you don’t usually eat, since it will be blended with the rest of the flavors in your smoothie. Seeds like chia seeds or ground flax seeds can also be added, which will not change the taste but will add nutrients.


I hope you are able to learn something from these simple tips, and that you’ll start adding more colorful foods to your diet!
