If you are referring to my pp where I copy and pasted a link titled: Is Guar Gum Healthy or Unhealthy, then no it is not suspect. I am a regular poster on Mumsnet for years. Easy enough to find out with a search. I do not work for, nor am I affiliated with Philadelphia cream cheese in any way and I have never been in the past.
Thx for sharing your link to a study on guar gum in a later post. I read it and found it interesting. This part stood out to me (copy and paste from your linked study):
Researchers noted that limitations of this study included the administration of a higher dose of guar gum than typically consumed daily by humans and the use of mouse models to investigate the relationship between IBD, diet, and microbiota, which may not accurately portray the interactions that occur in humans.
In the article that I linked, it covered that high doses of guar gum have negative health outcomes and can be fatal. It also referred to actual cases and studies that involved interactions of guar gum on actual people rather than mice. It was a well written, balanced article written by an expert who was not in any way affiliated with marketing any products at all.
Did you even read the article I linked in order to assess its validity?
Or did you just immediately jump to an assumption that I was just a part of a lame marketing ploy.
