Stimulating Effect of Red Beetroot (&i&Beta vulgaris&/i&) Juice, Fractioned by Membrane Ultrafiltration, on Iron Absorption in Chicken Intestines

摘要

Iron deficiency is one of the leading risk factors for disability and death worldwide. Targeted iron supplementation with pharmaceuticals is widely used, but oral iron salt ingestion often causes side effects—nausea, vomiting, abdominal pain. The present study demonstrated that red beetroot juice (RBRJ) contains a compound or compound complex with the ability to specifically stimulate duodenal iron absorption, shown in experiments in vitro , in situ and in vivo . The effect does not depend on juice sugar and ascorbic acid concentration. Fractionated RBRJ impact on iron absorption is dose dependent. This phenomenon is described for the first time.
