Extrusion cooking of a high-fibre cereal product

1. The effect of extrusion cooking, using mild conditions, of a high-fibre cereal product on apparent small bowel absorption of zinc, iron, calcium, magnesium and phosphorus was studied.2. Seven ileostomy subjects were studied during two periods (each of 4d), on a constant low-fibre diet supplemented with either 54 g/d of a bran-gluten-starch mixture or the corresponding extruded product.3. The apparent absorption of Zn, Mg and P was significantly decreased (P < 0.05) during the period with extruded product compared with the period with bran-gluten-starch. No difference was found for Fe and Ca.4. The negative effect of extrusion cooking of a product containing phytic acid on availability of Zn, Mg and P was small but could be of nutritional relevance in foodstuffs that are consumed frequently and in infant formulas.

1. The effect of extrusion cooking of a high-fibre cereal product on digestibility of starch, fibre components and phytate in the stomach and small intestine was studied by in vivo digestion in ileostomy subjects, as well as its effect on ileostomy losses of fat, nitrogen, sodium and potassium.2. Seven ileostomy subjects were studied during two periods (each of 4 d) while on a constant low-fibre diet supplemented with 54 g/d of a bran-gluten-starch mixture (period A) or the corresponding extruded product (period B).3. Extrusion cooking, using mild conditions, did not change the content of starch, dietary fibre components or phytate of the bran product, but the phytase (EC 3.1.3.26) activity was lost. During the period using the extruded bran product, there was a significant increase in recovery of phytate-phosphorus (period A, 44% of intake; period B, 73% of intake). The amount of fibre components, fat, fatty acids, N, Na, K, water and the ash weight of the ileostomy contents did not differ between the two periods. Only 0.6 and 0.7% respectively of ingested starch was recovered in ileostomy contents in periods A and B, while the fibre components were almost completely recovered.4. Extrusion cooking, using even mild conditions, may lead to a considerable impairment in the digestion of phytate, probably due to a qualitative change in phytate and a loss of phytase activity. Starch, before and after extrusion cooking, is almost completely digested in the stomach and small intestine while fibre components are digested to a very small extent.

Managing Stress

Understanding the distribution of Mãori across stages of health behaviour change (precontemplation, contemplation, preparation, action, maintenance) may inform the development of public health programs. In a replication and extension of a study by Nigg et al. (1999) we described the distribution of 73 Mãori male questionnaire respondents (age 18 to 59 years) across these stages for 8 healthy behaviours (avoiding dietary fat, eating fibre, reducing weight, regularly exercising, reducing stress, reducing sun exposure, using sunblock, and conducting cancer self-examinations). Respondents were also asked to rate their general health, health worries, and health locus of control. Evidence found of a continuum of change for ‘ignoring’, to ‘thinking about1 to ‘performing’ healthy behaviour provides moderate support for the idea that behaviour change is not an all-or-nothing event. There were no significant age effects. Respondents who rated their health more positively were more likely to report using sunblock, exercising regularly, and eating a high fibre diet. Respondents who felt they had more control over their health were more likely to eat a diet high in fibre. Eating a high fibre diet, exercising and managing stress were most strongly associated with the other health behaviours which may illustrate the concept of gateway behaviours proposed by Nigg et al. (1999).
