Travel expenses at 45p/mile (up to 25 miles radius) & an inconvenience payment will be reimbursed.


Volunteers need to:

  • Attend up to 3 to 7 test days (from 1 to 8 hours, plus a 2-hour next day visit)
  • Give blood, urine & faecal samples, & have blood pressure, insulin resistance, liver fat, lung & cognitive function measured
  • Follow some dietary restrictions for 21 days before and during the study.

Study update:

To date, a quarter of the study population have finished the 6-month food intervention, with almost all (93%) stating the experience was rewarding and that they would recommend participation to others.


Dr Peter Curtis, Senior Research Fellow and study coordinator said: “Although we still have much to learn, some studies have shown that regularly consuming blueberries can improve a wide range of health outcomes related to heart health and diabetes. This pioneering piece of research will help us to understand more about how blueberries effect our health and to also find out how many blueberries we need to eat in order to reap the benefits. ”
