中文简介:
维生素和矿物质在少量饮食中都是必不可少的。术语‘维生素’直到20世纪早期才开始描述食品中的这些化学物质,没有这些化学物质会出现缺乏症状(通常称为缺乏综合症)。矿物质,也称为矿物元素,是体内发现的碳,氢,氧和氮以外的元素。该单元研究了两大类维生素:脂溶性维生素A,D,E和K,以及水溶性维生素,B组和维生素C。它还检测了主要矿物元素,以及体液平衡的重要性。
课程简介: Both vitamins and minerals are essential in the diet in small quantities.The term ‘vitamin’ was not coined until early in the 20th century, to describe those chemicals in food without which a pattern of deficiency symptoms (often called a deficiency syndrome) occurs. Minerals, also called mineral elements, are those elements other than carbon, hydrogen, oxygen and nitrogen that are found in the body. This unit looks at the two main groups of vitamins: the fat-soluble vitamins A, D, E and K, and the water-soluble vitamins, those of the B group and vitamin C. It also examines the major mineral elements, and the importance of fluid balance in the body.
