Dietary Fibre: Chemical and Biological Aspects.

DIETARY FIBRE: CHEMICAL and BIOLOGICAL ASPECTS. Edited by D A T Southgate, K Waldron, I T Johnson and G R Fenwick. 386 pages with index. Price: 50.50 [pounds]. (UK: Royal Society of Chemistry)

As many readers will know, it is only comparatively recently that the importance of dietary fibre in our diet has begun to be fully appreciated. This has led to much research into the subject and many meetings about the topic, and indeed the Food Chemistry Group of the Royal Society of Chemistry organised just such a meeting. Fibre 90 dealt with both the chemical and biological aspects of dietary fibre and it recognised the fact that there was a need to bring together workers in the field.

Fibre in the diet is known to contribute to our wellbeing although quite how that occurs is not fully understood but the time is fast approaching when the various theories that have been propounded will need to be tested by application. In turn, the public will need to be fully informed of the result. It is rather chastening to think that in the UK we are mostly so relatively comfortable and well fed that such factors may be contributing to our downfall - our lack of understanding of the importance of dietary fibre could be vital here. The meeting, held last year, was divided into seven Parts with general titles: Dietary fibre, health and the consumer; Chemistry of dietary fibre; Analytical techniques; Effect of fibre on the small intestine: implications for digestion and nutrient absorption; Dietary fibre in the large intestine: implications for colorectal function and energy metabolism; Dietary fibre and lipid metabolism; and Dietary fibre and the food and pharmaceutical industries. In all there were some sixty or more presentations and we haven't the space to detail them all here but a selection of the titles runs as follows: Concepts of dietary fibre; Changes in dietary fibre polymers during storage and cooking; Chemical and physicochemical properties of fibres from algal extraction by-products; Biosynthesis of the hemicellulose, glucuronoxylan, in plant fibre; Evaluation of dietary fibre methods and the distribution of B-glucan among various fibre fractions; Analysis of the dietary fibre from Olea Europaea (Gordal and Manzilla var.); Influence of wheat breads containing guar flour supplements of high and low molecular weights on viscosity of jejunal digesta in the pig; Effects of two incorporation rates of guar gum on digestibility, plasma insulin and metabolites in resting dogs; Effects of dietary fibre on mineral balances in humans; Enhancement of colonic crypt proliferation in man by short-chain fatty acids; Estimation of the digestibilities of NSP for wholemeal bread and haricot beans fed in mixed diets; The effect of isolated complex carbohydrates on caecal and faecal short-chain fatty acids and stool output in rats; Do oats lower blood cholesterol?; Effects of rye bran, oat bran and soy bean fibre on lipid and bile metabolisms, gallbladder morphology in male Syrian hamsters; Dietary fibre enrichment, a sign of quality: possibilities in bread; and Sugar beet fibre: a clinical study in constipated patients.
