Inclusion criteria: 1. Males and females 2. Aged 40-65 years 3. BMI 18.5-30.0 4. Systolic blood pressure > 90 and 60 and <99. Blood pressure will be measured at the screening appointment, and if greater than 140 / 90 the volunteer will be referred to their GP before participation. If they are subsequently put onto blood pressure medication then they will be excluded from the study

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Blood pressure is measured after a 10 minute recumbent rest period. A minimum of 3 readings are taken and the first one is discarded. 24-hour blood pressure monitors are also used for the 24-hour following each timepoint. Readings are taken every 30 minutes between 7am and 10pm and then every hour from 10pm to 7am 2. Faecal samples are collected at each timepoint and analysed for bacterial composition and short chain fatty acid concentrations All primary outcomes are measured at the timepoints of weeks 0, 4, 10 and 16, with weeks 4 to 16 being the 12 week intervention period. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Fasted blood samples are analysed for blood lipid and glucose profiles and a range of inflammatory markers associated with cardiovascular disease, as well as short chain fatty concentrations 2. Urine samples are collected at weeks 4 and 16 and analysed for avenanthramide concentration as a marker of dietary compliance Secondary outcomes are measured at the timepoints weeks 0, 4, 10 and 16, with weeks 4 to 16 being the 12 week intervention period. | — |
