The present results suggest that SPM, the dominant phospholipid in milk, plays an important role in neonatal gut maturation during the suckling period.
Lactoferrin can solubilize over ,** molar equivalents of iron, and is expected as a natural iron solubilizer for food products and nutraceuticals from the viewpoints of bioavailability, safety, and productivity. To investigate the availability of iron solubilized by lactoferrin (FeLF) in humans, we recruited thirteen volunteers with serum hemoglobin values below +-g/dl blood and/or ferritin levels below ./ ng/dl serum and served them a supplement containing FeLF (1./ mg of iron) every day for twelve weeks. Significant increases in blood hemoglobin (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and serum ferritin concentrations were observed during the FeLf supplementation period. The hemoglobin level of three anemia subjects improved significantly during the period of FeLf supplementation, and, conversely, decreased after discontinuation of the supplementation. No side e#ects attributable to FeLf supplementation were observed either during or after the supplementation period. Thus, the results suggest that FeLf could be a useful food product for iron fortification to prevent anemia without the risk of toxicity often encountered with general iron supplementation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
