Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
We will be testing 4 different breakfast cereals, a conventional barley cereal, 2 new barley cereals and a refined cereal. Barley cereals are derived from Barley lines that differ in nutrient composition. Participants will consume each of the 4 test foods in 4 week blocks, with each test food period to be separated by 2 weeks. For the duration of the study participants will be required to consume their usual diet with some restrictions to ensure it is low in fibre. For each 4 week test period, they will be required to consume 50g of the test food daily. At the beginning of the study and at the end of each 4 week testing period participants will be required to attend the Clinic for a 15 minute appointment to discuss digestive health and prior to the visit collect a 48 hour faecal and urine collection and 3 short questionnaires (product consumption checklist, 3-day food diary and physical activity questionnaire). At baseline only, they will be required to undergo a whole body and forearm DEXA scan.
