Can diabetic clients eat FRUSSO? Can. FRUSSO would not consist of sucrose or glucose, only a little degree of fructose, and fructose will not cause a spike of blood sugar, so taking one or two sachets of FRUSSO on a daily basis won't affect the blood sugar of diabetic clients. https://www.onehealth.sg/2022/04/05/how-probiotics-affect-your-digestion/
