Effect of polydextrose and soluble maize fibre on energy metabolism, metabolic profile and appetite control in overweight men and women.

摘要: High-fibre diets offer several beneficial health effects. The objective of the present study was to investigate whether replacement 30 % available carbohydrates with polydextrose (PDX) or soluble maize fibre (SCF) at breakfast and lunch would result in an increased fat oxidation rate satiety, which may be relevance for body weight control diabetes prevention. In a single-blind, randomised cross-over study, eighteen overweight men women underwent four different dietary interventions, consisted PDX diet, SCF diet two (full energetic isoenergetic, comparable respect g energy percentage macronutrients, respectively). Glycaemic profile, expenditure substrate were measured 24 h respiration chamber. Circulating insulin, NEFA TAG concentrations determined over 14 period during daytime. Appetite ratings assessed using visual analogue scales. reduced peak glucose response, accompanied by postprandial insulin responses. Moreover, higher circulating observed after consumption both diets, h. This effect mainly attributed lower value not fibres per se. Besides increasing oxidation, exerted pronounced suppressive on appetite ratings. special interest because its effects metabolic profile it affect long term.
