Vitamin A encompasses a group of unsaturated nutritional organic compounds critical for maintaining overall health. Many foods deliver the health benefits of vitamin A, such as sweet potatoes, kale, carrots, and broccoli, along with certain meats, poultry, fish, and dairy products. A deficiency in vitamin A can have adverse consequences that compound as you age.
Vitamin A can improve vision and keep your eyes healthy. It is a critical component of the rhodopsin molecule, which is activated when light shines on the retina. The National Eye Institute found that high levels of antioxidants such as vitamin A may reduce the risk of developing advanced age-related macular degeneration by about 25 percent.
