Two important nutrients for brain health and cognition are found in eggs: choline and lutein. Choline plays a role in early brain development during pregnancy and infancy, particularly in areas of the brain that are used for memory and learning. Lutein has long been associated with eye health but research has discovered lutein’s role in cognition as well. For example:
- Researchers at the University of Illinois published two studies looking at the relationship between brain lutein, as measured using a non-invasive eye test called Macular Pigment Optical Density (MPOD), and cognition in children. They found that MPOD concentration was positively associated with academic performance.
- The American Medical Association (AMA) House of Delegates recommended the addition of choline to prenatal vitamins because of its essentiality in promoting cognitive development of the offspring.
- There is evidence that infants exposed to higher levels of maternal choline (930 mg/day) during the third trimester have improved information processing speed during the first year of life, an indicator of cognition and intelligence.
