Cravings for high-calorie foods can be reduced by gut bacteria-based supplement

07/07/2016

Cravings for high-calorie foods can be reduced by gut bacteria-based supplementMost people get cravings for high-calories foods, such as chocolate and pizza, from time to time. But new research suggests that such cravings can be reduced by consuming a supplement called inulin-propionate ester.

Researchers from Imperial College London and the University of Glasgow found that study participants who drank milkshakes containing the gut bacteria-based supplement were less likely to crave high-calorie foods.

Presenting their findings in The American Journal of Clinical Nutrition, the researchers said the supplement works by increasing the amount of propionate in the gut - a compound that is released naturally when a person consumes the fibre inulin, which is found in artichokes, bananas and asparagus.

Inulin slows digestion, increase fullness and reduces appetite, and it is already used as a dietary supplement today.

For the study, the researchers asked a group of 20 healthy men to drink milkshakes. Half of the group's milkshakes contained inulin-propionate ester, while the other half contained just inulin alone.

The researchers then showed the men pictures of different foods; some high calorie, some low calorie. The study participants' brain activities were monitored throughout to see how they reacted to the various pictures.

The group that drank the milkshakes containing inulin-propionate ester displayed reduced activity in their brains' reward centres - the caudate and the nucleus accumbens (both associated with food cravings) - but only when they were looking at images of high-calorie foods.

In addition to being showed the food images, the men were then given equal-sized bowls of pasta and told to eat as much as they wanted. The inulin-propionate ester group consumed around 10% less than their inulin only counterparts.

Dr. Douglas Morrison from the University of Glasgow, who co-authored the study, said that the research illustrates how important gut microbiota signals are for regulating appetite and influencing people's food choices.
