Question

: if Potassium, Calcium, Sodium and Magnesium are metals. How are some foods rich/contain such metals?

Answer 1

Foods contain salts of those metals. That is, positively charged metal ions bound to negatively charged ions (usually chloride).

These ions are extremely important to the functioning of your body. The movement of sodium, calcium, and potassium ions is how your body generates electrical charges that allow for signals that control your nerves and muscles, for example.
