Lutein is an important carotenoid tied to optimal brain and eye health. Currently, no Reference Daily Intake (RDI) is established for lutein, leaving a gap in awareness around this critical nutrient. Registered dietitian nutritionists should understand the concerns about excess blue light from digital devices, LED lights and sunlight, and the role of lutein as part of the "internal sunglasses" protecting photoreceptor cells. Research supports a role for lutein in slowing the progression of age-related eye diseases. Emerging research extends beyond eye health, with benefits tied to cognitive function and brain health across the lifespan. Higher brain levels of lutein are related to better cognitive function in preadolescent children and young and older adults. The session will conclude by translating the science to registered dietitian nutritionists by providing guidance on how to incorporate food sources of lutein into the diet. Additionally, the differences in supplemental lutein sources will be discussed.
