Summary
This narrative review, published in the Journal of the American College of Nutrition (JACN) in 2010, synthesises evidence on choline as an essential nutrient, covering its biochemical functions, recommended intake levels, and principal dietary sources. The paper likely highlights that choline is critical for liver function, brain development, and methyl group metabolism, and that many individuals — particularly pregnant women — do not meet recommended adequate intake levels. It serves as a foundational reference for understanding choline's nutritional importance and the public health implications of widespread insufficiency.
UK applicability
Although the paper is likely framed around US dietary reference values and food supply data, its core biochemical and nutritional findings are directly applicable to UK populations and are relevant to UK dietary assessment given that choline has historically been absent from UK nutrient intake surveys and food composition databases.
Key measures
Adequate intake values (mg/day); dietary choline intake estimates by population group; choline content of food sources; biomarkers of choline status (e.g. plasma choline, homocysteine)
Outcomes reported
The paper reviews choline's physiological roles, dietary requirements across life stages, common food sources, and the health consequences of inadequate intake. It likely reports on population-level shortfalls in choline consumption relative to established adequate intake levels.
