High salt diet could be damaging our brain

TOO MUCH IS TOO BAD.

Scientists at Weill Cornell Medicine in the US have found that the tiny crystals of salty goodness that we all love so much could be impeding blood flow to the learning and memory centres of the brain, leading to cognitive impairment and dementia. At least that’s the case with mice fed on a high-salt diet. The percentage of salt in their diet was as high as 8% but the study does raise questions about the connection between our gut and the brain. The good news, however, is that the damage caused by impaired blood flow is reversible, with normality setting in after four weeks of consuming a regular, healthy diet. For reference, the Heart Foundation recommends adults consume no more than 5g of salt per day.
