The Health Effects of High Sodium

August 10, 2013 by HealthyFamilies BC


HealthyFamilies BC is committed to providing British Columbians with the information they need to make healthy lifestyle choices.

We recommend reduction of dietary sodium as a key factor in healthy eating to reduce the incidence of high blood pressure, stroke, heart disease and kidney disease.

Some recent scientific reports have raised questions about the role of sodium and population health.These recent studies demonstrate the need for ongoing research in this area but do not provide enough evidence to change current thinking and practice about limiting sodium intake.

Heart Health

About one-third of people are sensitive to sodium. Eating too much sodium can cause high blood pressure, stroke, heart disease and kidney disease. Over time, high blood pressure can damage blood vessel walls. It can also strain the heart and eventually weaken it. High blood pressure is the leading preventable risk factor for death around the world. It is often called a "silent killer" because it has no warning signs or symptoms. You can't see it. You can't feel it. But the good news is that you can control it.

DID YOU KNOW? High blood pressure or hypertension affects 1 in 5 Canadians. It's the number one risk factor for stroke and a major risk factor for heart disease.

Check Your Blood Pressure

Be sure to have your blood pressure checked every two years by your family doctor or other qualified health care provider. If you have high blood pressure, you can reduce it by lowering your sodium intake little by little each day.

Kidney Health

Eating a diet high in salt intake results in high blood pressure and can also cause kidney disease. As a result you are unable to rid your body of excess fluids and wastes. Over time loss of your kidney function means that you will need to restrict certain foods and possibly require dialysis or a kidney transplant.
