The level of sodium in the body is regulated by the [[renin-angiotensin-aldosterone system]] (RAAS) and by [[anti-diuretic hormone]] (ADH). <section end="clinical biochemistry" /> | |||

Too much sodium in the diet increases the risk of cardiovascular disease. Most people today eat much more sodium than is recommended. | |||
