Can diabetic sufferers eat FRUSSO? Can. FRUSSO will not contain sucrose or glucose, only a small degree of fructose, and fructose will not cause a spike of blood sugar, so having 1 or two sachets of FRUSSO on a daily basis would not affect the blood sugar of diabetic clients. https://www.onehealth.sg/2022/04/05/how-probiotics-affect-your-digestion/
