The physical properties and the chemical variety of the substances which make up the plant cell wall are inadequately described by any one term such as "fibre". It would seem that an understanding of the role of the unavailable carbohydrates and lignin in the diet in the functioning of the gastro-intestinal tract and on possible pathological process must be based on a better knowledge of the chemical and physical properties of these substances as they occur in foods than is at present available. It is suggested that this knowledge can come from a synthesis of the findings of the plant anatomists, plant biochemists and structural organic chemists and the application of this synthesis to studies in man.
构成植物细胞壁的物质，其物理性质和化学多样性无法用“纤维”这样的单一术语充分描述。看来，要理解饮食中不可利用的碳水化合物和木质素在胃肠道功能以及可能的病理过程中的作用，必须比目前所掌握的知识更深入地了解这些物质在食物中的化学和物理性质。建议通过综合植物解剖学家、植物生物化学家和结构有机化学家的研究结果，并将这种综合应用于人体研究来获取这方面的知识。
