Potassium

Functions of potassium are fluid balance and nerve impulse transmission. Increasing potassium intake is associated with lower rather than higher blood pressure values. We absorb about 90% of the potassium we eat.

Low blood potassium is a life-threatening problem. Symptoms often include a loss of appetite, muscle cramps, confusion, and constipation. Eventually, the heart beats irregularly, which decreases its capacity to pump blood.

Sources of potassium are milk, potatoes, beef, coffee, tomatoes, orange juice.
