Yabbers people are within their rights to avoid chemicals in food if they choose, and within their rights to give their opinion of them, when explaining why they want to avoid them.
You have the choice to either take their opinions, and links, on board, or not. If you are not concerned about the potential risks that have been mooted, that's fine. I didn't see anybody sneer at those who don't agree they might be harmful, and I am wondering which posts you read that into. All I see is people explaining why they avoid them. If you are happy in your choice, why would you be getting angry about other peoples' opinions or eating habits?
It really ISN'T easy to avoid sweeteners, as they are on bloody everything these days, even where they have no business to be. I found them in a jar of gherkins last week, quite unexpectedly, and it was a very nasty surprise. That's another food I used to enjoy that has now been denied to me. I'm guessing you don't see the issue because you are not trying to avoid them, and therefore haven't had to waste loads of your own time and money.
I don't want to have to spend three times as long as necessary in the supermarket poring over the small print on labels, to see which formerly tasty foods have been tuined. Food manufacturers should be labelling the change on the front of packs, before tricking people into buying them. After all, if this is a positive change, and the food tastes just as good
, and there are no health concerns, what could possibly be the reason to hide it?
