Sodium (Na)

Why do we need sodium?

Sodium is a major mineral, which along with potassium, is needed to control your blood pressure and the water balance in the cells of the body. It also helps in muscle contraction and sending nerve impulses. The amount of sodium in the body fluids is controlled by the kidneys.

Sources of sodium

Sodium is found in table salt, soy sauce, bread, cheese, bacon, ham, fruit, crisps and sweets.

What happens if I eat too much?

Too much sodium can result in high blood pressure which increases the risk of strokes and coronary heart disease. It is also a factor in Oedema ( fluid retention ), and kidney stones. The more sodium you have, the more potassium you need to contradict its effects.

What happens if I don't eat enough?

Sodium deficiency is unlikely, but if it does occur symptoms include thirst, cramps, fatigue and weakness.

How much should I have?
