A high-salt diet in mice leads to cognitive issues and reduced synaptic protein levels due to changes in gut microbiota and short-chain fatty acid production.
Mice with gut microbiota from high-salt diet-fed mice show impaired memory and synapse function when placed on a regular diet.
Treatment with butyrate, a short-chain fatty acid, helps improve memory impairments in mice that were on a high-salt diet, highlighting the gut microbiome's significant role in cognitive health.
