What the study showed, in plain terms

Published in 2013, this source examined food sources, absorption and nutrient metabolism. It examined Food-frequency estimates linked to nutrient-composition databases. The source describes 188147 Multiethnic Cohort participants aged 45-75.

Estimated choline and betaine intakes varied by sex and ethnic group; database matching made population-level intake analysis feasible.

Many food values required matching or imputation; intake estimates cannot establish causality.

Key findings

  • Estimated choline and betaine intakes varied by sex and ethnic group; database matching made population-level intake analysis feasible.
  • The recorded outcome domains were Dietary betaine; Ethnic variation; Measurement methods.

What this study can and cannot tell us

  • Many food values required matching or imputation; intake estimates cannot establish causality.
  • Source basis: Indexed abstract and bibliographic data. Missing method details, funding information or participant denominators are not inferred.
