Salt Linked to Memory Decline in Older Men, Study Finds
A six-year observational study of over 1,200 older Australians found that higher salt intake was associated with a decline in episodic memory among men (not women). While not proving causation, researchers note that sodium-related vascular and inflammatory changes, including higher blood pressure and reduced brain blood flow, could contribute to memory aging. The study reinforces guidance to limit sodium (WHO recommends under 2000 mg/day) as part of a brain-healthy lifestyle, especially for older men.
