Abstract
High salt (HS) intake induces hypertension and cognitive impairment. Preventive strategies include against dietary supplements. Soybean lecithin is a widely used phospholipid supplement. Lysolecithin is important in cell signaling, digestion, and absorption. This study aimed to investigate the effects of lysophosphatidylcholine containing >70% of the total phospholipids (LPC70), on hypertension and cognitive impairment induced in mice by HS intake. Mice were provided with HS solution (2% NaCl in drinking water) with or without LPC70 for 12 weeks. Blood pressure, cognitive function, and inflammatory response of intestine were determined. Hypertension and impaired object recognition memory induced by HS intake were implicated with increased inducible nitric oxide synthase in the small intestine and tau hyperphosphorylation in the prefrontal cortex. LPC70 treatment prevented cognitive impairment by suppressing inducible nitric oxide synthase and tau hyperphosphorylation. LPC70 may be valuable as a functional food component in preventing HS-induced cognitive impairment.
