Grapes are small, round or oval berries that grow in clusters on woody vines of the genus Vitis, and they are among the oldest cultivated fruits in human history, with origins tracing back to the Near East and Mediterranean regions. Grapes are widely consumed fresh as table fruit, dried into raisins, or processed into products such as juice, jam, vinegar, and especially wine, making them economically and culturally significant across many societies. Nutritionally, grapes are a good source of vitamins C and K, along with antioxidants and beneficial plant compounds like flavonoids, resveratrol, and quercetin, which are known for their potential to reduce inflammation and support heart health. Resveratrol, found particularly in the skin of red and purple grapes, has been studied for its role in protecting blood vessels, lowering LDL cholesterol, and promoting longevity-related mechanisms.

Grapes also contain natural sugars, primarily glucose and fructose, providing quick energy, along with dietary fiber that aids digestion. Their high water content helps with hydration, while their low to moderate calorie density makes them a healthy snack option. Grapes are grown in diverse climates worldwide, with major producers including countries such as China, Italy, and the United States, and they play a central role in agriculture, cuisine, and the global wine industry.
