The effect of nutrient-extraction blender preparation of raspberries on Postprandial Glucose response in Adults.

 Increasing fruit consumption may reduce the risk of several chronic diseases. The nutrient extraction blender is a new method to consume fruit; however, health risks remain unclear. Nutrient-extraction blenders are designed to homogenize the whole fruit without removing the fiber; conversely, old-style juicers squeeze the juice and remove the pulp. This study aimed to understand the effect of nutrient-extraction of raspberries on the glycemic response in healthy weight adults and overweight/obese, who are at risk of glucose intolerance. A total of 9 HW and 5 OW/OB adults were recruited to participate. Participants fasted for 12h overnight and then consumed raspberries with mango as whole fruit (WF), nutrient-extracted (NE) or a glucose control (C) (all 25g total sugar/ serving). Blood glucose levels were obtained via finger prick blood samples with a minimum 3-day washout period between test days. Glycaemic index was calculated from the incremental area under the 2-h glucose response curve for each meal. Multiple comparisons post-hoc (Turkey HSD) was conducted to determine the difference between meals. GI was significantly different between all conditions with mean ±SD (C, 100 ±37.07), (WF, 72.07 ± 28.54), (NE, 43.31 ±23.57), (p<0.001), but there were no differences between healthy weight and overweight / obese. The postprandial glucose response from NE raspberries was significantly lower than both WF and C. Whereas, other published findings demonstrated that the consumption of nutrient-extracted mango alone was not significantly different from the whole mango. These results show that homogenized raspberries could be a potential approach for glycaemic control.
