In addition to fruits and vegetables, which of the following can be a source of antioxidants?

Red wine is often recognized as a source of antioxidants due to the presence of compounds like resveratrol, flavonoids, and tannins, which are believed to provide health benefits. These antioxidants help combat oxidative stress in the body, potentially reducing the risk of chronic diseases. The fermentation process of wine, especially red wine which is made from the whole grape and retains more of its skin, allows for a higher concentration of these beneficial compounds compared to white wine or other beverages.

In contrast, caffeinated beverages typically do not have significant antioxidant properties, dairy products are not known primarily for their antioxidant capacity, and while processed foods may contain various substances, they often lack the concentrated beneficial antioxidants found naturally in items like red wine. This makes red wine a more favorable option when considering sources of antioxidants beyond fruits and vegetables.
