Brief summary

Fibre intakes in developed countries are generally below those recommended by relevant authorities. Given that many people consume fibre-depleted refined-grain products, adding functional fibre will help to increase fibre intakes. The objective of the study was to determine metabolic and sensory effects of adding fibre to bread.

Interventions

Two fibre rich breads were baked. One bread contained 15 g/serve (two slices) of FibreMax (New Image International, Auckland, New Zealand). The other bread contained 15 g per serve of a prototype fiber extracted from a fruit product manufactured by Anagenix (Petone, New Zealand). Participants were randomized to one of the breads. The two slices of bread were consumed following a fasting period of at least 3 hours. Participants were also randomized to order of consumption of their fibre-enriched

The two slices of bread were consumed following a fasting period of at least 3 hours. Participants were also randomized to order of consumption of their fibre-enriched bread or of a control bread without added fibre. The fibre bread and the control bread were consumed with a two week separation between clinic visits.
