Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
We will be testing 4 cereals that differ in their nutrient composition. The 4 cereal types will deliver 1. high, 2. moderate-high, 3. moderate or 4. low (negative control) levels of dietary fibre. For the study duration participants will follow their habitual dietary pattern with some restrictions to ensure it is low in fibre. This is a parallel study design, with participants randomised to one of four groups. Participants will be asked to consume 100g of the test food daily for an 8 week testing period. At baseline participants will undergo a DXA total body, forearm and lumbar spine scan. Each fortnight participants will attend the clinic for a fasted blood sample and to complete 2 short questionnaires (product consumption checklist and 3 day food diary) and prior to the visit collect a 48 hour urine. At week 8 participants will undergo a dual stable isotope test.
