Functional implications of maternal intake of flaxseed and its by-products during pregnancy and lactation on offspring

Abstract

Purpose The purpose of this review of the literature is to provide data about flaxseed intake during pregnancy and/or lactation and its effects in the offspring from birth to adulthood. Design/methodology/approach This review includes up-to-date information from evidence-based sources on flaxseed intake and its by-products, during pregnancy and lactation and its effects on male and female offspring, from post-weaning until adulthood. Topics included are effects on body mass; glycaemic metabolism; lipid profile; blood pressure and aortic structure; reproductive system and brain tissue. Findings The main effects of flaxseed or its by-products were observed in the cardiovascular system, where a lipid profile improvement and minor aortic remodelling were noticed, and in the cerebral development, where greater n-3 PUFA incorporation in the brain was detected. Originality/value The research done in this study, to understand the offspring response that were early exposed to the flaxseed components during pregnancy and lactation, may be the first step toward guiding future strategies for recommending the use of this seed during the offspring’s perinatal period.
