Zeaxanthin is a powerful antioxidant that has been receiving a lot of attention lately due to its potential health benefits. In this article, we will explore what zeaxanthin is, where it’s found, its health benefits, and potential side effects. Furthermore, we’ll discuss how much zeaxanthin is needed to experience these benefits, as well as the best food sources for this important nutrient.
What is Zeaxanthin and Where is it Found?
Zeaxanthin is a naturally occurring carotenoid pigment that is found in various plant-based foods, particularly leafy greens, fruits, and vegetables. It is often found in conjunction with another carotenoid called lutein. In fact, zeaxanthin and lutein are the only carotenoids found in the macula of the human eye. The macula is the area of the retina that is responsible for high visual acuity and is affected by age-related macular degeneration (AMD).
Studies have shown that consuming foods rich in zeaxanthin and lutein can help reduce the risk of developing AMD. Some of the best sources of zeaxanthin include kale, spinach, broccoli, peas, and corn. Additionally, zeaxanthin can also be found in egg yolks and some types of seafood, such as salmon and shrimp. It is important to include these foods in your diet to maintain good eye health and prevent age-related vision loss.
The Health Benefits of Zeaxanthin
Zeaxanthin has been found to exhibit various health benefits in the human body. One of the primary benefits is its ability to support and protect eye health.
