Fatty acid intakes in healthy adults quantified using a food frequency questionnaire compared with red blood cell membrane fatty acid content: A validation study
Self-reported intakes from the Australian Eating Survey food frequency questionnaire were in moderate agreement (ρ<sub>c</sub> = 0.20-0.60) with red blood cell membrane fatty acids. This questionnaire may be used as an indicator of self-reported long-term dietary fatty acid intake in Australian adults, with caveats for individuals reporting extreme intakes and consideration for evaluating the effects of endogenous synthesis of fatty acids. Future studies are warranted to replicate findings and strengthen translation to other sub-populations.
