Resveratrol in the Mediterranean Diet

• Grape Skins and Red Wine
• Resveratrol is a polyphenol and phytonutrient found primarily in the skins of red grapes.
• Because red wine is fermented with the grape skins for a longer period compared to white wine, red wine is the primary alcoholic source of resveratrol in the Mediterranean diet.

• Nutritional and Biochemical Context
• Antioxidant Properties: Resveratrol acts as a potent biological antioxidant, helping to neutralize free radicals and reduce oxidative stress in tissues.
• Cardiovascular Support: Within the context of the Mediterranean diet, moderate consumption of red wine contributes to cardiovascular health by supporting healthy endothelial function and circulation.
• Synergistic Effects: The health benefits of the Mediterranean diet come from the synergy of all its components, including fresh produce, healthy fats like olive oil, and various polyphenols working together, rather than any single nutrient in isolation.

• Important Considerations
• Moderation is Essential: Excessive alcohol consumption negates potential health benefits and introduces significant health risks.
• Alternative Sources: For individuals who do not consume alcohol, resveratrol and related bioflavonoids can also be obtained directly by eating fresh red grapes, purple grape juice, blueberries, and cranberries.
