答案     Minerals
    Minerals are non-organic substances which contain the element carbon. / But they are vital for good health / and have many key roles to play in the body. / Minerals needed daily are present in almost all cells of the body. /
    Acute imbalances of the daily needed minerals can be potentially fatal. / On one hand, mineral shortages may lead to health problems / such as failure to thrive in babies and an increased risk of heart disease. / On the other hand, taking in too many dietary minerals can also harm the body. / For example, too much calcium in the blood / may cause vomiting, loss of appetite and irregular heart rate. /
