Why does the body need vitamins and minerals?

If the body receives adequate vitamins and minerals It will help in making the body's immune system work effectively. Because vitamins and minerals play an important role in helping increase white blood cells and create antibodies. But when the body does not receive enough vitamins and minerals to use, it causes the immune system to work inefficiently, including making it easier for the body to pick up various germs and viruses.
