SYDNEY, April 15 (Bernama-Xinhua) -- A diet high in salt may accelerate memory decline in men, Australian research reveals, highlighting the importance of dietary choices in supporting brain health, reported Xinhua.
The study found that higher sodium intake may impair episodic memory, which enables people to recall personal experiences and past events, such as where you parked your car or your first day of school, said a statement from Australia's Edith Cowan University (ECU) released on Wednesday.
Measuring baseline sodium intake and cognitive decline of 1,208 participants over 72 months, researchers found that men with higher sodium intake experienced faster episodic memory decline, while no link was seen in women.
While sodium serves several physiological functions and is inextricably linked to the maintenance of the body, high sodium consumption has consistently been associated with an increased risk of cardiovascular events and high blood pressure, according to the study published in Neurobiology of Aging.
Lead researcher Samantha Gardener from ECU said that while the molecular mechanisms behind the process were not yet understood, it was thought that high sodium intake could contribute to inflammation in the brain, damage to blood vessels, and reduced blood flow to the brain.
