Question

why we should cut down intake of common salt in case of high blood pressure

Answer 1

Hey frnd !!

Eating too much salt is the biggest cause of high blood pressure - the more salt you eat, the higher your blood pressure will be.
It  makes your body retain water. If you eat too much, the extra water stored in your body raises your blood pressure. This can be a particular problem if you have high blood pressure. Also, eating too much salt may mean that blood pressure medicines, such as diuretics, don't work as well..
