Health Benefits

The muscadine grape is truly a nutritional powerhouse. Like most berries and richly colored fruits and vegetables, the muscadine is a rich source of polyphenols. The skins are particularly rich in the polyphenolic compound resveratrol, which has been studied for its antioxidant benefits in numerous diseases, including cancer and heart disease.

Muscadine Nutrition Facts

One serving of grapes is about 1/2 cup, or 16 grapes. That amount of muscadines has:

  • 55 calories
  • 0.78 grams of protein
  • 0.45 g of fat
  • 13.37 g of carbohydrate
  • 3.37 g of fiber
  • They are also about 84 percent water.

They are fat free, cholesterol free, sodium free, an excellent source of manganese, and a good source of fiber.

Muscadine Polyphenols

Polyphenols from foods are widely studied to support the function of brain, heart, liver, joints, muscle recovery, and other organs. As antioxidants, they support the body’s cellular function and recovery from normal metabolism, and reduce oxidative stress and inflammation associated with many disease states. The highest concentration of these healthful phytonutrients are in the skins and seeds of the grapes

Muscadine’s polyphenols include both resveratrol and ellagic acid, two antioxidants that are found in red wine, pomegranate and berries. Resveratrol is a well-researched antioxidant that is shown to extend lifespan in animals, act on mitochondria to improve metabolic function, and possess a number of beneficial activities when consumed.  Ellagic acid and gallic acid, plus the polyphenolic tannins from which they are derived during ripening and processing, are potent antioxidants that have metabolic, anti-inflammatory and anti-cancer activities.

Muscadines also contain flavonoids such as anthocyanins and quercetin, which give muscadines their purple-red or yellow hue respectively, and have been. Scientific studies, such as cell culture studies, animal models, and human clinical trials, show that anthocyanidins and anthocyanins possess antioxidative and antimicrobial activities, improve visual and neurological health, and protect against various non-communicable diseases. Quercetin is a more powerful antioxidant than vitamin C, vitamin E, or beta carotene.
