We’re doing a short series on foods that boost eye health, and first of the list is leafy greens!
The antioxidants lutein and zeaxanthin, found in leafy greens, are significantly important nutrients for eye health, They are classed as caroteniods (a type of phytonutrient), which are present in the macula, the central part of the retina responsible for central vision. The macula also acts as a shield for the eye, protecting it from damaging light.
Both lutein and zeaxanthin have been linked to a lower risk of cataracts and macular degeneration, which is the leading cause of visual loss in those aged over 60. In a review led by Billy Hammond, professor of neuroscience and experimental physiology at the University of Georgia, a team of researchers described the identification of 600 carotenoids in nature, of which around 20 are present in the human circulation. Of those, only lutein and zeaxanthin are found in the eye.
The highest concentrations of lutein and zeaxanthin can be found in spinach, kale and brussel sprouts. So to help protect your eyes and keep your vision sharp, why not add more of these superfoods to your diet today!?
