Purple has long been regarded as the color of royalty. It’s rich and prodigious.
This translates to the food world, with blueberries and acai being labeled as “superfoods” and an increasing amount of plants being bioengineered to have this special hue.

I can’t deny that purple is an amazingly beautiful color, but does its reputation hold true when it comes to our health? Let’s explore.
What You’ll Learn
What Makes Fruits and Vegetables Purple?
Fruits and vegetables get their colors from different phytochemicals. These compounds, made within the plant, also give them their taste and smell.
Anthocyanins are phytochemicals that give off a deep red, purple, or blue hue, and you’ll find these in many types of produce, including blueberries, cranberries, red cabbage, and plums. They also color many types of flowers.
Other types of phytochemicals can also give produce rich colorful hues. Beets get their color from betalains. Red grapes are colored by anthocyanins, but also contain resveratrol, a phytochemical with its own distinctive advantages
Whoa – that was a lot of big words. The takeaway is this: plants make their own special chemicals that allow them to have unique colors and flavors.
Farmers can also use selective breeding to make certain foods colorful. You may have seen different colored carrots or cauliflower in grocery stores. While the standard commercially available cultivars don’t grow this way, special cultivars can provide additional phytochemical benefits.
Health Benefits of Eating Purple Foods
When we eat a variety of colorful plants, all of these phytochemicals act as antioxidants in our bodies. This is why foods with a high concentration of them (I’m looking at you, blueberries and pomegranates) often get a reputation for being superfoods.
Antioxidants combat free radicals in our bodies. Free radicals can cause direct damage to our cells, so you can see why counteracting them is potentially beneficial. Antioxidants prevent the harmful effects of free radicals, and may work to protect our bodies against certain cancers and cardiovascular diseases.
Should You Eat More Purple Foods?
With all of these potent antioxidant benefits, it seems that it’s a good idea to include more colorful foods in your diet. Increasing our intake of these foods is definitely beneficial to overall health.
Let’s not get it twisted, though. While these foods offer remarkable advantages, so do other colors of fruits and vegetables!
Yes, you should eat more of them, but also more orange, red, yellow, green, and white plant-based foods. No single food is a superhero, coming to save your diet.
