Fructooligosaccharide intake is linked to better insulin resistance, lower levels of Romboutsia ilealis bacteria, and changes in GLP-1 hormone in obese mice on a high-fat diet

Fructooligosaccharides (FOS) may influence insulin resistance and GLP-1 production in high-fat diet-induced obese mice.

• Obesity is linked to disrupted glucose regulation and insulin signaling due to changes in gut hormone levels and inflammation in the intestines.
• Previous findings indicated that FOS can reduce inflammation in the colon and alter gut bacteria when combined with vitamin D.
• The specific impact of FOS on insulin resistance and GLP-1 production during obesity is not yet fully understood.
• This research focuses on evaluating how FOS affects these metabolic changes in a mouse model of obesity induced by a high-fat diet.
