The results suggest the time people spend chewing may be an important factor in determining their energy intake. This supports earlier research suggesting drinks may not be the most effective format for developing food products for satiety.
The study found that when participants chewed food for one minute, they ate the same amount as they did on an empty stomach, regardless of how much food had already been infused in to their stomach.
However, when participants chewed for eight minutes they consumed significantly less than they did on an empty stomach.
Dr Alfrun Erkner, a Nestlé Research Center scientist involved in the study, said: “Our findings suggest longer oral-sensory stimulation may be an important factor in lowering energy intake.
“This doesn’t necessarily mean specially designed nutrition beverages can’t have a satiating effect, but that products that provide increased oral stimulation could be more effective. Follow-up studies are needed for a better understanding of the impact of the interaction of oral and gastric factors on eating behaviour.”
