4.7. Intervention and Control Meal
The tested product was a commercial, proprietary extract of the brown seaweed The control meal consisted of 108 g or approximately two white bread buns (Bundy’s originals, Johnston Mooney and O’Brien Bakery, Dublin, Ireland) that provided 50 g of available carbohydrates as measured by the commercial kit (Megazyme International Ireland Ltd., Bray, Ireland) and was always served fresh. The intervention meal consisted of the same amount of white bread (108 g or approximately 2 buns) and either 500 mg or 1000 mg of the brown seaweed extract distributed evenly between the two bun halves. Intervention and control meals were prepared daily according to the allocation sequence by technical staff not included in the trial and served in a double-blinded fashion (to participants and researchers). However, due to the taste of the extract, subjects were ultimately not considered blinded as they reported the taste revealed the higher dose intervention.
