This aim of this study is to investigate the prebiotic potential of date fruits in healthy human volunteers compared to a control diet. Each arm was 21 days in duration, separated by a 14 days washout period. Faecal samples, and blood samples will be collected from each volunteer and high resolution analytical techniques (HPLC, LC-MS and NMR) will be employed to characterise the whole system metabolic response to ingestion of date fruits compared to the control. Changes in microbial parameters and metabolite profiles will be correlated with changes in biomarkers of chronic disease, including faecal water genotoxicity, cellular reactions, blood lipids and bowel movements.

Inclusion Criteria: - Signed consent form - Body mass index - 18.5 - 30 inclusive - Age 18 - 55 years - Good general health as determined by medical questionnaires Requirements for diet and medication during study - No intake of additional supplementary prebiotics (i.e. such as fructo-oligosaccharides) - please note that consumption of foods that are naturally prebiotic, e.g. cereal grains and leeks, may be consumed as normal - No intake of probiotics (i.e. live yoghurts), drugs active on gastrointestinal motility, antibiotic treatment or any class of laxative - All concomitant medication must be recorded in diaries and case record forms - Usual diet, fluid intake and exercise levels should be maintained during trial period - Please inform the investigator if you consume antibiotics during the trial. You will not be able to continue, as this may affect your faecal bacteria.
