@Poshpots - Going back to your orignal post - as an 83 year old T2 woman, I work on the simple basis that when I buy processed food if more ingredients sound like chemicals than actual food then that's definitely off limits for me, though my favourite "Er what!!" combination so far has been frozen prawns with added sugar...
I also came across this discussion now, even though it’s a bit old. In the meantime, I found out that the term “ultra-processed” isn’t just a nutritionist buzzword, but it’s actually the basis for lawsuits in the U.S.
