Dietary Flaxseed as a Strategy for Improving Human Health

Mihir Parikh et al. Nutrients. 2019.

Abstract

Flaxseed is a rich source of the omega-3 fatty acid, alpha linolenic acid, the lignan secoisolariciresinol diglucoside and fiber. These compounds provide bioactivity of value to the health of animals and humans through their anti-inflammatory action, anti-oxidative capacity and lipid modulating properties. The characteristics of ingesting flaxseed or its bioactive components are discussed in this article. The benefits of administering flaxseed or the individual bioactive components on health and disease are also discussed in this review. Specifically, the current evidence on the benefits or limitations of dietary flaxseed in a variety of cardiovascular diseases, cancer, gastro-intestinal health and brain development and function, as well as hormonal status in menopausal women, are comprehensive topics for discussion.

Keywords: cancer; cardiovascular; diabetes; flaxseed; functional food; menopause; microbiome; nutraceutical.

Individual values of systolic blood pressure at baseline or after 6 months of dietary supplementation with a placebo (A) or 30 g of milled flaxseed per day (B). Baseline systolic blood pressures in the placebo group were 143.5 ± 2.88 at baseline and 144.8 ± 3.33 after 6 months (n = 36). Baseline systolic blood pressures in the flax group were 146.6 ± 3.37 at baseline and 136.5 ± 3.53 after 6 months (n = 41). Results are obtained from Rodriguez-Leyva et al, 2013 [5].
