If you’re supplementing probiotics, there is some research about inulin to talk through with your doctor. There’s a chance that inulin is carcinogenic even at lower doses. A lower dosage might be 4g and a typical probiotic is 200g.
Reasons to be wary of this research, including:
-The rodent-to-human study element
-causation v correlation
-sample size
Reasons to take this research seriously:
-Probiotic supplements are relatively new and long term effects aren’t understood.
-The “health as a business” realities that are very much at work here.
