A satiating experience or not?


From October 2009 newsletter     
Smoothie

The findings from a feeding trial to determine the satiating effect of a specially formulated smoothie-type product will help industry in their efforts to produce hunger-reducing foods and drinks.

The trial involved young males being fed a mid-morning strawberry smoothie - either the test smoothie containing inulin and guar gum or a control product containing starch, designed to taste the same and provide the same amount of energy.They were later fed a buffet style lunch, and instructed to 'eat until comfortably full'.They could request any number of extra items from the buffet 'menu'. At various times they were also asked to fill in a questionnaire about their appetite.

There were no differences in the liking of the two smoothie products, confirming that any satiating effects were not due to differences in liking between the two samples.There were some significant differences in the self-reported appetite ratings. For example, participants felt significantly less hungry 30 minutes after consuming the test smoothie than after consuming the control smoothie. Despite this and other positive appetite findings, this did not lead to a reduction in the amount of food consumed in the subsequent buffet meal - either in terms of weight of food or energy content.
