Omega-3 fatty acids status in human subjects estimated using a food frequency questionnaire and plasma phospholipids levels

摘要

BackgroundIntakes of omega-3 (n-3) fatty acids (FA) are associated with several health benefits. The aim of this study was to verify whether intakes of n-3 FA estimated from a food frequency questionnaire (FFQ) correlate with n-3 FA levels measured in plasma phospholipids (PL).
