Phytoestrogens, while they can be found in fruits and vegetables, are not classified as antioxidants. Instead, they are plant-derived compounds that mimic estrogen in the body and have a different primary role related to hormone balance and regulation. In contrast, beta-carotene, flavonoids, and quercetin are well-established as types of antioxidants. Beta-carotene, for instance, is a precursor to vitamin A and helps combat oxidative stress. Flavonoids are a diverse group of phytonutrients known for their antioxidant properties, contributing to the overall health benefits of consuming fruits and vegetables. Quercetin is specifically recognized for its powerful antioxidant effects and anti-inflammatory properties. Each of these compounds plays a significant role in protecting cells from free radical damage, underscoring their classification as antioxidants.
