This 2012 review article examines the role of carotenoids—fat-soluble pigments found in fruits and vegetables—in cardiovascular health. Carotenoids, such as beta-carotene, lycopene, lutein, and zeaxanthin, possess antioxidant properties that can neutralize reactive oxygen species (ROS), thereby reducing oxidative stress—a key factor in atherosclerosis development. The review highlights that carotenoids may
This 2014 review evaluates the role of antioxidants in counteracting oxidative stress caused by ultraviolet radiation (UVR), a key factor in skin carcinogenesis. It explains how UVR leads to the generation of reactive oxygen species (ROS) that damage DNA, proteins, and lipids, accelerating skin aging and promoting cancer. The body’s
This systematic review evaluated the use of antioxidant supplementation—such as vitamins C and E, beta-carotene, selenium, glutathione, and N-acetylcysteine—in managing lung disease in individuals with cystic fibrosis (CF). While the review found a potential link between oxidative status and lung function, the evidence was limited by study variability, inconsistent outcomes,
