Soy lysolecithin counters high-salt diet-induced hypertension and cognitive impairment
High-salt (HS) intake is a major global health concern, closely linked to hypertension and growing evidence of cognitive and emotional decline. Although salt is a routine part of daily diets, long-term overconsumption can negatively affect both the cardiovascular system and the central nervous system, underscoring the need for practical dietary strategies to mitigate these adverse health effects.
High-salt diets are a significant global health issue, contributing to hypertension and cognitive decline. Soy lysolecithin, specifically LPC70, has been shown to mitigate these effects in mice fed a high-salt diet. LPC70 works by regulating prostaglandin (PG) signaling and arachidonic acid (AA) derived PG production, which are organ-specific processes.
In the kidney, LPC70 reduced enzymes involved in PG signaling (COX-2 and EP3), while in the brain, it restored expression of a neuroprotective receptor (DP1) and increased arachidonic acid-derived PGE2 and PGD2. These changes helped normalize maladaptive PG signaling and reduced hypertension, social deficits, and object-recognition memory impairment in the mice.
LPC70's ability to promote receptor-dependent PG signaling may make it a promising functional food ingredient for mitigating the negative health effects of high-salt diets, supporting cardiovascular and cognitive health, particularly in populations with high dietary salt intake.
