Glycaemic responses to carbohydrates ingested as fruit sugars may vary depending on factors inherent to the fruit and the type of sugar. The aim of this project is to investigate the glycaemic responses to a range of commercially available fruit drinks and to establish the glycaemic index for each product relative to a glucose reference. Differences in recorded responses could also be influenced by the sample type (capillary blood vs interstitial fluid) and participant characteristics. Participants will ingest 8 test drinks including 5 different fruit drinks (OJ, AJ, S\&B, ENERGISE, BLUE), each matched for carbohydrate to the glucose reference (CONTROL) which will be sampled two times, an additional sample of one of the smoothies (S\&B) will also be replicated. Fingerstick capillary blood sampling alongside dual sited continuous glucose monitors (CGM) will measure glucose and lactate concentrations, subjective appetite sensations will also be recorded. The tests will follow best practice guidelines for glycaemic index testing. These data will provide insight into how differing formulations can alter the glycaemic responses to fruit drinks, and whether sampling technique can affect the interpretations of measurement.
NCT01341769
The purpose of this study is to assess the effects of added food ingredients, when baked into a snack food product, on glycaemic index of the product and glycaemic and insulinemic responses to the product in healthy adults.
NCT03769389
Fruit of the date palm (P. dactylifera) may be considered as an emerging and potential candidate for the development of health-promoting foods, owing to its high nutritional values. Furthermore, aqueous extracts of dates have previously been shown to have potent antioxidant activity, because they inhibit in vitro lipid and protein oxidation and possess free radical scavenging capacity. Although the high sugar content of date fruit has always been a concern, date fruit has been regarded as a low-GI to medium-GI food. However, very limited, inconsistent and contradictory information is available on the glycaemic index values of different date varieties, which may be attributed to both the methodology as well as other food factors. Date consumption is high among people of Arabic origin, where it's very common for them to be eaten with coffee or yoghurt. Therefore, in view of these concerns, the objective of this trial is to evaluate the glycaemic response of two different varieties of dates, named Birhi \& Khassab, in an early maturation stage (Rutab stage), when mixed with 0% fat yogurt, on ten healthy participants aged between 18 and 45.
NCT01536847
The purpose of this study is to assess whether added food ingredient(s) affect glycemic responses to a liquid meal tolerance test (LMTT).
