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. / They can ensure our internal systems function efficiently. / Without minerals, the body would not be able to build new tissues, / regulate body processes or release energy from food. / 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. / Thus mineral shortages or taking excessive minerals / should be carefully avoided through a balanced diet in our daily life. /
解析     矿物质
   矿物质并非有机物质，但却对我们的健康至关重要。每日所需的矿物质几乎存在于身体的所有细胞中。无论是缺乏矿物质还是摄入过多膳食矿物质都会有损身体健康。因此，在日常生活中我们应该通过均衡的饮食，谨防矿物质缺乏或者过量摄取矿物质的情况。
