Purple Produce: Discover the Health Benefits of Purple Fruits and VegetablesPurple – it was the favorite color of the Egyptian queen Cleopatra. In some cultures, the color purple symbolizes royalty. With such lofty connotations, it’s not surprising that the color purple means good things when you enjoy it naturally in foods. Next time you’re at a produce stand or farmer’s market, check out the rich array of purple that comes naturally from the soil. You’ll find richly-colored blueberries, blackberries, and grapes, but purple isn’t just the domain of fruits. In the veggie department, you’ll find red cabbage, eggplant, purple kale, beets, purple cauliflower, and turnips read for you to enjoy. What makes purple produce such a healthy choice for the dinner table?

The Cell Protective Power of Purple

Purple fruits and vegetables get their pleasing purple color from plant compounds called anthocyanins. In plants, anthocyanins attract pollinating animals that help the plant spread its seeds, but they also appear to have some pretty powerful health benefits in humans as well. Anthocyanins belong to a class of compounds called flavonoids, potent antioxidants that protect cells against damage and reduce inflammation.

According to James Joseph a neuroscientist at Tufts University, purple is the color to look for when choosing produce. One reason is anthocyanins accumulate in the brain and eye tissue where they may have benefits for brain and visual health. The retina is very metabolically active and susceptible to oxidative damage, and anthocyanins may offer some protection against damage.

Purple Fruits and Veggies: Other Reasons to Love the Color Purple

Brain and visual health isn’t the only reason to munch on purple. Research suggests that anthocyanins may reduce the risk of other chronic diseases such as heart disease, type 2 diabetes, and cancer, likely due to their anti-inflammatory effect. The results are particularly compelling for heart disease since anthocyanins not only reduce inflammation but lower blood pressure and cholesterol levels, all of which are risk factors for heart disease. In addition, anthocyanins also inhibit the growth of certain types of cancer cells and activate detoxifying enzymes in the liver that break down carcinogens.

Purple Produce and Obesity

If that isn’t enough, anthocyanins from purple vegetables and fruits may be good for your waistline too. A study carried out in 2010 found that adults who ate the most purple produce had lower BMIs and smaller waist circumferences. In mice, anthocyanins offer protection against obesity in mice fed a high-fat diet. Of course, eating veggies of all types are good for your waistline, but purple veggies may have additional benefits due to the large quantities of anthocyanins they contain.

How to Add More Purple to Your Diet

Despite the apparent health benefits, most people don’t get enough purple produce in their diet. Here are some simple ways to get more purple on your plate:

Add slithers of raw red cabbage to your next garden salad.
Make a purple smoothie using plain Greek yogurt, blackberries, and blueberries.
Sprinkle purple berries on your oatmeal in the morning.
Make coleslaw with red cabbage.
Look for purple cauliflower at the grocery store and use it in place of regular cauliflower.
Skip processed potato chips and make purple kale chips by sprinkling pieces of purple kale with olive oil and baking them until they’re crisp.
Have stuffed red cabbage rolls as a main course, and add red cabbage to soups and stews.

The Bottom Line?

The next time you’re at your farmer’s market or produce stand, think purple. It’ll make your plate more colorful and give you additional health benefits as well.
