The New Scientist article notes that four of the seven human subjects who consumed three to four sachets of sweetener a day saw a significant change in their gut bacteria.
As someone who has consumed significantly more than that for a very long time, my question would be, did their gut flora reconstitute itself after they stopped using the sweetener? And if not, how could you go about repopulating your microbiome short of a stool sample?
The gut flora is as resilient as any other part of human body. It might take a significant time though. I've heard Korean food helps a lot because it's fermented. Also usual bifido youghurts you'll find at any grocery store.
The does in the article is higher than your post: 3-4 sachets taken 3 times a day.
Those packets to me are sweet. I alternate between honey and half a packet in my tea.
Gut Flora do come back (eg after taking antibiotics which cuts them down). They're crowded in there, so the ratio of them is important. Everyone has different ratio and there is no easy way to measure and control that.
