i see milk tasting almost like water like skimmed milk, as well as some juices i used to be able to buy, fillings in sweets like crackers and wafers being almost as thin as paper or outright stopping being sold and replaced by cookies using drops for a filling, yogurt being replaced by “milk drink” (yogurt is thicker and slower to flow down, i can tell the difference, but the label also changes, idk the english term for “bebida láctea”), a lot of sweets and bags reducing from 800g down to 600g, down to 400g while keeping the same price, packaging turning opaque and non-transparent, potato chips and other salt foods being filled 1/5th, down from 1/3rd, even instant noodles going from 150g down to 80g in the past decade.

only things that aren’t changed as much is what i know to be the very basic things that people in here uses and cooks every day, that being rice (5kg), beans (5 and 1kg), pasta (500g all variants), sugar and salt (1kg), etc.
mostly depends on the country you are in (i’m in Brazil), but the point is that it doesn’t stop at the chocolate bars.
