Potassium
Description
Potassium is an essential mineral that performs several vital functions in the body. Potassium and sodium are involved in maintaining the acid-base balance of the body and the fluids within the cells. Potassium is involved in the transmission of nerve impulses. It is also essential for muscle contractions, including those of the heart. Potassium plays a role in the activity of the kidneys as well as in the metabolism of carbohydrates.
In general, a diet rich in fruit and vegetables can cover the daily requirement of potassium (4.7 g).
However, in some countries it is not as simple as that, since the average daily intake of potassium in Canadians and Americans is insufficient, at only 2.3 g for women and 3.1 g for men.
All foods contain potassium, including fruits and vegetables: white beans (1g/100g), halibut (576mg/100g), potatoes (550mg/100g) and tomato puree (460mg/100g).
