What natural antioxidants work well against different free radicals? Research shows that plant-based (botanical) antioxidants can provide broad-spectrum protection against these radicals. However, plant sources of antioxidants seem to “specialize.” A botanical source (such as blueberry, tomato, cocoa, or green tea) generally has high concentrations of a particular family of antioxidant compounds (such as anthocyanins, carotenoids, proanthocyanidins, or flavonoids). These compounds tend to perform better against some radicals than others.
Here are some general guidelines:
Proanthocyanidins (PACs)—superoxide anion and hydroxyl

New research published in Journal of Agricultural and Food Chemistry, reported that University of California, Los Angeles (UCLA) researchers were able to identify four additional carotenoids in the California Hass avocado, which had not been quantified until this study. In addition, the researchers reported that the total carotenoid concentrations were greatest in the dark green flesh of the avocado closest to the peel. Carotenoids are a class of phytonutrients. Phytonutrients are thought to help prevent many chronic diseases.
