Grapes are a major source of several phytochemicals like flavonoids, polyphenols, anthocyanins, proanthocyanidins, procyanidins, and stilbene derivative resveratrol. Whole grape juice would contain all these phytochemicals.

As would be expected, grapes are rich in carbohydrates; although, a lot of it is dietary fiber.

They have been found to possess antioxidative, anti-inflammatory, antimicrobial, cardioprotective, hepatoprotective, and neuroprotective properties (Nassiri— Asl et al., 2009 and Nassiri –Asl et al., 2016). However, the phytochemical composition of grapes varies greatly among different varieties (Jun Yang et al., 2012).

Research has shown that the health-promoting antioxidant properties may be influenced by harvest time, pre-processing ethylene treatment of grapes, and juice thermal pasteurization (Genova et al., 2016)

Flavonoids found in red wine are said to help lower LDL (bad cholesterol). AHA does not recommend the consumption of wine, as contrary to popular belief, it doesn’t reduce the risk of heart diseases.

If the choice is between whole grape juice and red wine, my vote would be in favor of whole grape juice. Provided, of course, if you are not pre-diabetic.
