The main objective is to investigate gut microflora composition in relation to cardiometabolic risk markers, and to investigate the effects of 3 days intervention with a barley kernel based product on these variables.

100 subjects were invited to deliver faecal samples. From this cohort 40 subjects were chosen based on their gut microflora composition to participate in the Barley intervention.

Inclusion Criteria:

• healthy men and women between 50-79 years and
• BMI between 19-28.

Exclusion Criteria:

• fasting blood glucose concentrations > 6,1 mmol/L,
• known metabolic disorders or gastrointestinal diseases or other disorders that can interfere with the results of the study.
• furthermore, the subjects should be non-smokers and
• consume a normal (non-vegetarian) diet as is recommended by the Nordic dietary guidelines.
• antibiotics or probiotics should not have been taken during four weeks prior to faeces donation.
