GLUCOSE INTOLERANCE, RECRUITMENT
Volunteers were recruited using a flyer that briefly described the study. The initial appointment was made with the volunteers for pre-screening. The volunteers were asked initial recruitment questions to determine their suitability to take part in the study. The nature of the study and their involvement and responsibilities were described to them. Each volunteer was presented with an information sheet, containing study details, and an informed consent form. Volunteers who were willing to participate were asked to complete the General Health Questionnaire (GHQ) and had a capillary blood glucose test to check that their blood glucose and HbA1c were in the normal range (fasting blood glucose < 6.0 mmol/L, HbA1c < 40 mmol/mol). This was also to familiarise them with the blood sampling procedure to be used in the study should they volunteer to take part. Exclusion criteria included recent ill-health as gauged by the GHQ or self-report, known intolerance of kiwifruit or wheat products, and glucose intolerance as indicated by the fasting blood glucose and HbA1c in the preliminary test. All participants signed the informed consent form before participating in the study.
