"There's plenty of questionable sources of information out there on the internet."
At the time you curated this post, it had no corroborating links (they were edited in after I complained). How can a wall of unsubstantiated text ever be a good source of "discussion and sharing of information"? From my other comment on this post:
"I tried to substantiate the claim myself, but quickly found this article debunking it."
(Also, the corroborating link added now is "Natural News", which has the same credibility level as The Onion or National Enquirer.)
Serious claims require serious evidence, or they're just rumour and slander.
A quick search on any search engine reveals this hoax has been spread rampantly for 8 years.
"HEK293 cells are a cell line widely used in biological and medical research, immortalised through a genetic modification and many, many generations removed from the original human embryonic kidney cells taken from a healthy, electively aborted human fetus in the early 1970s.[3] The receptors in the assay are used to identify flavours; they are not used as flavours themselves. No human taste receptors are used as ingredients in any flavourings."
More here, here, here, and dozens of other sites. This hoax has been around since 2011 and is perpetuated mainly by anti-abortionists who believe (or pretend to believe) there are human fetal tissues being added to products, or used in their development, and neither is true.
I thought you'd be very interested to know you're promoting disinfo when that's the opposite of your goal. I'm not trying to start a fight or anything, sorry for any misunderstanding.
