High-Salt Diet Increases Alzheimer’s Risk- Study 0

We know that consuming high salt food is not good for the heart. It is linked to blood pressure, hypertension and cardiac problems. Now, a new study has found that a diet high in salt can even be harmful to the brain health, thus increasing the chances of chronic neurodegenerative conditions like Alzheimer’s disease.

According to the study, published in Nature Neuroscience, eating too much salt can lead to an increased risk of Alzheimer’s disease. As per the researchers, foods that are high in salt causes an inflammatory immune response that cuts the supply of oxygen to the brain and harms neurons. This causes mental and behavioural problems in people.

For the purpose of the study, the researchers fed the mice eight to 16 times their normal salt intake, and within three months time, the mice became demented.

“After about three months, the mice became demented. Mice are very curious and they like to look for new things, and so over time the mouse lost the ability to identify a normal object,” said the lead study author Constantino Iadecola.

Interestingly, once the mice were taken off their salty diets for four weeks, their brain scans showed normal blood flow and healthy endothelial function. The reversal of brain health indicates that healthy lifestyle changes will bring back our body to normalcy.

Recommended Salt Intake Limit

It is advisable that people should not consume more than 5 grams of salt a day.
