A comprehensive review of eggs, choline, and lutein on cognition across the life-span

Since the choline and xanthophyll carotenoid lutein found in eggs are implicated with influencing human cognitive function, Wallace (2018) critically evaluates the impact of eggs, choline, and lutein on cognition across the life-span. This review reports that although choline and lutein is seen as vital in brain and neurological development during the first 1000 days post-conception, data on its effects during childhood, adulthood, and on age-related cognitive decline is limited. Lutein is in fact being increasingly suggested to be capable of affecting cognition across the life-span and if taken sufficiently during mid- to late adulthood can help delay the progress of age-related cognitive impairment. This review provides a summary of the current pertinent peer-reviewed literature and identifies gaps in research. Macular pigment optical density (MPOD) is highlighted as a reliable and consistent biomarker for brain lutein levels and possibly for clinically assessing cognitive status.

A fat to forget: Trans fat consumption and memory

This 2015 study analyzed the data from the 1999-2005 UCSD Statin Study (involving 1018 adult men and non-procreative women aged ≥20 without diagnosed diabetes, CVD, or extreme LDL-cholesterol) to determine a possible association between dietary trans fatty acid (dTFA) consumption with word-memory. “Recurrent words” tasks helped assess word memory, while the participants’ estimated daily dTFA […]

Obesity and overweight conditions place fifth on the list of causes of preventable deaths across the world. Being overweight is implicit in negative overall health due to several factors, including enhanced inflammatory conditions and cognitive derangements. Previous evidence postulates the presence of a vicious cycle where obesity leads to enhanced inflammatory activity that results in […]
