Thank you for that! I eat a small bag of crisps - the ones from a multipack once or twice a week - there is 13g of carbs in a bag, I don't have a sweet tooth at all and never eat a little bit of scone or a small bit of cake or a bit of a kit Kat or even much "good" chocolate - I have just finished my dark choc from Christmas this week - crisps are my treat that I build into my food for that day - it's all about testing as the OP did to see if you can tolerate them not just taking at face value what other people say you can can't eatUnlikely to be good.
Whoever is telling you it's good is probably a gibbering idiot.
