The following research projects are supported by the Foundation:
Prevention of Diabetes in Europe and Worldwide (PREVIEW): The aim of the study is to determine the impact of a high protein, low glycemic index diet in combination with physical activity on the incidence of type two diabetes in overweight children and adults.
Prof Jennie Brand-Miller is leading the work program responsible for communicating and exploiting the findings of PREVIEW to convert new knowledge into strategies to reduce the risk of diabetes, including web-based lifestyle interventions for the public and collaborations between food industry and health professionals on development of innovative products and ingredients.
Australian Health Survey Sub-Analysis:
This study aimed to determine the major food groups contributing to dietary glycaemic load (GL). Plausible food intake data collected using a multiple-pass 24 hour recall from a weighted sample of 6326 adult respondents (52% male) of the 2011-2012 Australian Health Survey dataset (AHS) were analysed. The mean (SD) dietary GI and GL was 54 (7) and 135 (59) respectively and the top 3 contributors to dietary GL were breads (14.4%), cereal-based dishes (10.3%) and breakfast cereals (ready to eat) (6.6%). There were small but significant differences in the GL contribution pattern between the sexes. The findings indicate that the average dietary GI of Australian adults is similar to that of other population groups, with a large proportion of starchy and energy-dense nutrient-poor foods that contribute to a high GL.
This study aimed to examine the dietary glycaemic index (GI) and glycaemic load (GL) of Australian children and adolescents, as well as the major food groups contributing to GL, in the recent 2011-2012 Australian Health Survey. The paper concluded that, Australian children and adolescents appear to consume diets with a lower GI than European children. Exchanging high-GI foods for low-GI alternatives within core and non-core foods may improve diet quality of Australian children and adolescents.
Australians have used the glycemic index (GI) since 1995; however, there are no data on changes in carbohydrate quality over time. The aim of the study was to compare average dietary GI and glycemic load (GL), and contributing carbohydrate foods, in the 2 most recent national dietary surveys. Although the average dietary GI and GL declined between 1995 and, trends in specific carbohydrate foods suggest that Australians are avoiding potatoes and sugary beverages in favor of a greater variety of carbohydrate foods, particularly cereal products.
Potatoes are a popular source of dietary carbohydrate worldwide and are generally considered to be a high glycemic index (GI) food. Potato starch characteristics play a key role in determining their rate of digestion and resulting glycemic response.The Glycaemic Index (GI) status of Carisma potatoes was established in a joint project between Sydney University and the Mitolo Group. The research was carried out by Kai Lin Ek, while working in the Faculty of Agriculture and Environment at the University of Sydney. The research showed that Carisma achieved the lowest GI compared to a number of potato varieties. Since the initial research, further testing and research has continued on Carisma and other potato varieties.
