Scientific title
Study objectivesLong-term consumption of bran-rich cereal products impacts favourably on risk factors for heart disease and metabolic syndrome in apparently healthy, 'at risk' men and women.
Ethics approval(s)The study was approved by the University of Ulster Research Ethics Committee in March 2007 (ref: REC/07/0016).
Health condition(s) or problem(s) studiedChronic diseases, particularly cardiovascular disease and cancers
InterventionVolunteers were stratified by age and sex and randomly assigned into the test or control group:
1. Test group: 3 x high-bran products per day for 4 weeks (1 x ready-to-eat cereal + 2 x bread products)
2. Control group: 3 x refined high-fibre products per day for 4 weeks (1 x ready-to-eat cereal + 2 x bread products)

Test and control products were balanced for energy, fibre and macronutrients and incorporated by volunteers into their normal diet.
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Specified
Drug / device / biological / vaccine name(s)Bran-rich cereal products
Primary outcome measureChanges in plasma homocysteine (a risk marker for CHD) attributable to treatment during the intervention, measured at baseline and 4 weeks.
Secondary outcome measuresChanges in other risk markers for disease attributable to treatments during the intervention:
1. Inflammatory markers and endothelial function
2. Antioxidant status
3. Lipid profile
4. Relevant micronutrient levels
5. Insulin and glucose levels

Outcomes measured at baseline and 4 weeks.
