HVN Kiwi, Fruity and Friendly 3 Metadata Record - Metabolic effects of kiwifruit in people with prediabetes

This metadata record and it's attached files make statements about the kinds of data collected as part of this research, and set out policies for governance of that data, now and in the future.
Description: This trial focused on participants who were of mixed race but who were all pre-diabetic and therefore had a high risk of developing diabetes. As before, the aim was to determine whether or not increased intakes of fructose due to consumption of two kiwifruit per day over a long period could cause harmful metabolic changes in individuals judged by medical criteria as being at high risk of ‘metabolic syndrome’.
The third trial ran for three months – enough time for glycosylated haemoglobin (HbA1c) concentrations in the blood to register increased exposure to glycaemia during the trial period. Several clinical biomarkers were measured, as well as plasma Vitamin C. There were no differences between the kiwifruit and control (water) groups in weight gain, blood lipids, HbA1c and other clinical measures, while plasma Vitamin C increased in the kiwifruit group.
The results showed that kiwifruit, although containing fruit sugars, may be consumed as an excellent source of Vitamin C, by people at risk of diabetes, without unwanted metabolic side effects.
