Even if they don't provide us with calories, minerals are extremely useful for the organism. For example, did you know that it is iron that carries oxygen in the blood?
Calcium, on the other hand, is not only important to strengthen bones and teeth, but it also allows muscles to contract, and therefore it makes your heartbeat possible.
Sodium and potassium allow the transmission of electircal signals through nerves, sending messages along all your body.
And the health of teeth enamel depends from fluoride.
Basically without this small mine, our organism could not survive.
Although they are all necessary, only about 15 of these are particularly important and they must be taken through foods. And, like vitamins, minerals also need to be etane in small quantities, and a varied and balanced diet contains enough quantities.
If eaten in excess, they can have serious consequences. Too much iron, for example, causes a dangerous liver, pancreas and heart overload.
Minerals contained in foods of animal origin are absorbed by the organism faster than the ones found in vegetables.
