Glycemic and Insulinemic Impact of Selected Canadian Beans (MED-beans)
19. september 2016 opdateret af: Dan Ramdath, Guelph Food Research Centre
The objective of this study is to compare the glycemic and insulinemic response elicited by ½ cup servings of 6 beans to those elicited by ½ cup servings of mashed potato, macaroni, rice and corn.

Detaljeret beskrivelse
In order for a food to be able to claim a reduced glycemic response, it must be shown that a typical serving of the food elicits a significantly lower blood glucose responses compared to a serving of an appropriate control food.
While many studies have examined the GI of beans, few studies have compared the glycemic impact of a typical serving of beans to a typical serving of other starchy foods.
Therefore, there are insufficient data to allow for a claim that beans have a low glycemic response.
In addition, in order to make a claim of a reduced glycemic response, regulatory agencies also require that the insulinemic response to a food is not disproportionately increased.
