Systematic review of the evidence for a relationship between DHA and maintenance of normal brain function and normal vision

(July 2016)

Executive summary

FSANZ has conducted a systematic review on dietary deficiency of DHA and the maintenance of normal brain and vision functions. In doing this review, FSANZ has followed the requirements of the Application Handbook and of Schedule 6 of Standard 1.2.7 - Nutrition, Health and Related Claims, for the required elements of a systematic review.

FSANZ identified five case studies in which seriously ill patients received DHA. However, none of these studies assessed any aspect of brain or vision functions after the intervention.

Due to the lack of suitable human studies of DHA and maintenance of normal brain and vision functions, FSANZ regards the two relationships that are the subject of this review as being 'non-assessable'.
