When it comes to maintaining optimal health, we often think about vitamins and minerals, but one nutrient that doesn’t always get enough attention is lutein. This powerful carotenoid is best known for its role in promoting eye health and is also a key player in skin health, cognitive function, and more. In this comprehensive guide, we will explore what lutein is, why it’s so important, and which foods you should include in your diet to reap its benefits.
What is Lutein?
Lutein is a type of carotenoid, a pigment found in various plants that gives many fruits and vegetables their vibrant colors. It’s classified as a non-provitamin A carotenoid, which means it does not convert into vitamin A in the body. Instead, lutein functions primarily as an antioxidant, combating oxidative stress that can damage cells.
Found mainly in green leafy vegetables, lutein is concentrated in the macula of the eye, which is responsible for central vision. As we age, the amount of lutein in our body naturally decreases, which is why it’s important to include lutein-rich foods in our daily diet.
