8 Surprising Facts About Concord Grapes
Talk about purple power -- the pigment that gives Concord grapes their distinctive hue is responsible for the (super) fruit's super powers. Here are some, er, grape reasons to add more purple produce, including Concord grapes, to your shopping cart:
They may improve your health. Purple may be the color of royalty, but purple-hued foods signify improved health. One study found that Americans who eat purple and/or blue fruits and veggies (Concord grapes, blueberries, plums, eggplant) had smaller waistlines, lower blood pressure and reduced markers of inflammation compared to those who didn't eat purple/blue foods.
They provide benefits similar to red wine. Many of the beneficial polyphenols found in Concord grapes are the same as those present in red wine. Hundreds of studies conducted over decades show that these natural compounds promote cardiovascular health.

They're nutrient-rich. About 19 Concord grapes (one handful) contain around 30 calories and equal 1/2 cup or one serving of fruit. And, if you're sipping 100 percent grape juice, you're scoring the same beneficial polyphenols of the fruit because the beverage is made from the skin, seeds and flesh of Concord grapes. Cheers to that!
They contain compounds that fight free radicals. While human clinical trials are limited, mounting laboratory, animal-model and other types of research studies suggest that purple foods, such as Concord grapes, blueberries and plums, can neutralize free radicals that can cause DNA damage when left unchecked.
They relax your arteries. Relaxed arteries are considered healthy arteries. Two decades' worth of research shows that Concord grapes and 100 percent grape juice are good for the heart and help maintain clean and flexible arteries that improve blood flow. This is thanks to the potent polyphenols in the super fruit.

They help keep your mind sharp. Concord grapes, grape juice and red wine may also help maintain grey matter as you age. That means an improvement in cognitive function and a reduced risk for declines in memory, due to the beneficial cardiovascular and anti-inflammatory properties, according to laboratory, animal model and small human clinical trials.
They're natural performance-enhancers. Studies on antioxidant supplements suggest a reduction in markers for inflammation among athletes. One small human clinical trail that included 12 adult runners reported that those who supplemented their diet with purple grape juice had improved endurance.

They may help boost immunity. One study of 85 middle-aged adults found that those who were given 100 percent grape juice daily for nine weeks (in the absence of eating any other blue/purple foods) had an increase in a certain type of immune system cell compared to those who drank a placebo beverage.
