Plant carotenoids are the primary dietary source of provitamin A worldwide, with β-Carotene as the most well-known provitamin A carotenoid. Carotene is the substance in carrots, pumpkins and sweet potatoes that colours them orange and is the most common form of carotene in plants. Absorption of β-Carotene is enhanced if eaten with fats, as carotenes are fat soluble.
