| Scientific title | |
| Study objectives | Long-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) studied | Chronic diseases, particularly cardiovascular disease and cancers |
| Intervention | Volunteers 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 type | Drug |
| Phase | Not Specified |
| Drug / device / biological / vaccine name(s) | Bran-rich cereal products |
| Primary outcome measure(s) |
Changes in plasma homocysteine (a risk marker for CHD) attributable to treatment during the intervention, measured at baseline and 4 weeks. |
| Key secondary outcome measure(s) |
Changes in other risk markers for disease attributable to treatments during the intervention: |
