Everyone needs salt in their diet to keep their body functioning, but too much salt is damaging in many ways. Excessive salt in the blood causes the kidneys to store up more fluid so that it can dilute blood as it passes through the organs. This can also alter the sodium-potassium balance in the kidneys and reduce kidney function overall.
Sodium also increases urinary calcium, which can cause kidney stones – especially in people with already high blood pressure. This is common in those who maintain high-salt diets. Most of your salt intake comes from sodium that is already in the food you’re cooking. Avoid adding extra salt to your dishes whenever possible.
