A new study from the University of Surrey found that young women taking prebiotic supplements for four weeks choose healthier foods and consume less sugar
.
The prebiotic used in this study is galactose oligosaccharide (GOS), which can increase the number of "friendly" gut bacteria
.
In a paper published in the journal Nutrition, researchers at the University of Surrey set out to investigate whether prebiotic GOS can affect the eating habits of 48 healthy young women aged 18 to 25
.
The women were divided into two groups, one group took GOS supplements (BiotisTM) and the other group took a placebo for 28 days
.
The women were asked to record their eating habits; the researchers also collected stool samples for microbiome sequencing
The research team found that compared with women in the placebo group, women taking GOS supplements reduced their total sugar intake by 4.
1% and carbohydrate intake by 4.
3%
.
Interestingly, the study also found that people taking GOS supplements consume 4.
After analyzing their results, the Surrey team found that prebiotic supplements changed the composition of the gut microbiota and increased the level of bifidobacteria
.
Researchers found that these changes are related to women's nutritional intake during the four-week period
The lead author of the study, Dr.
Catherine Cohen Kadosh from the University of Surrey said
"In this study, we observed the impact of prebiotic intake on the health of young women
.
For a long time, stress and anxiety have been blamed on "comfort diet", and more and more evidence supports the effect of stress on unhealthy eating behaviors.
"This research, combined with our previous research, shows that promoting the growth of beneficial bacteria in the gut, such as prebiotic-containing bifidobacteria, can improve health by reducing anxiety and may help make healthier food choices
.
"
Dr.
Nicholas Johnstone from the University of Surrey is a co-author of the study.
She added:
"So far, our research clearly shows that prebiotics such as galactose oligosaccharides can effectively promote the growth of intestinal bacteria, which may have a positive impact on our diet and feelings
.
" Now, we need to do more.
