What is a health risk associated with high sodium intake?

High sodium intake is closely linked to high blood pressure, also known as hypertension. When there is an excessive amount of sodium in the bloodstream, it can cause the body to retain water, which increases the volume of blood in circulation. This increased blood volume puts greater pressure on the walls of blood vessels, thereby raising blood pressure. Prolonged high blood pressure can lead to significant health issues, including an increased risk of heart disease, stroke, and kidney disease.

The other options either suggest benefits that are not associated with high sodium intake or do not relate to health risks. Increased vitamin absorption, improved muscle recovery, and better hydration are not outcomes of high sodium consumption and can even be negatively impacted by excessive sodium levels. Thus, the association of high sodium intake with high blood pressure is a well-established health risk.
