“全合成食物”一词,“全”的定义系指它包含所有已知的、或认为是满足人体生长、维持及修复所需要的营养素;“合成”系指这些食物大多数是以元素或分子水平的物质制成的。单一的完全食物的发展依赖于对人体需要的全部营养素的知识,目前这样完整的知识尚未具备。关于主要营养素之间的适宜关系,特别是关于微量元素的性质及作用,正在进行着大量的研究工作。 The term “fully synthetic foods” means “whole” in the sense that it contains all nutrients that are known or believed to satisfy the growth, maintenance and repair of the human body; “synthetic” means that most of these foods are expressed as elements or Made of substances at the molecular level. The development of a single complete food relies on the knowledge of all nutrients that the body needs, and so far such complete knowledge is not yet available. There is a great deal of research going on about the appropriate relationship between major nutrients, especially with regard to the nature and role of trace elements.
