Other studies show that diabetics have less butyrate-producing bacteria species in the gut compared to non-diabetes patients and diabetes patients who are taking metformin. Moreover, studies demonstrate that resistant starch increases the butyrate-producing bacteria species. Furthermore, studies show that butyrate has on effect on blood glucose and insulin homeostasis.~The aim in this study is to investigate, if resistant starch typ III increases butyrate-producing bacteria in the gut of (pre-) diabetic subjects, The effects on blood glucose, insulin and HbA1c are investigated as well.~Patients included in the study are typ 2 diabetics with lifestyle interventions, insulin or antidiabetic medication (sulfonylureas, glinides, SGLT2-inhibitors, glitazone) or pre-diabetics.~They get 2x 5g per day the food supplement SymbioIntest (resistant starch types III) over 8 weeks.~Study examinations are before intervention, after 4 weeks and 8 weeks. Stool samples are collected before intervention and each 14 days consecutively until the end of intervention.
The aim of the study is to investigate, if resistant starch type III increases butyrate-producing bacteria in the gut of (pre-) diabetic subjects. Diabetic blood parameters are also of interest.
