A gallon of milk is still a gallon of milk. A pound of carrots is still a pound of carrots.
It sounds as if your basket of goods is different from mine. Most of the examples on that Wikipedia page are sugary foods, which I just don't buy a lot of.
Here, two pounds of carrots are $1.79, just as they have been for as long as I can remember. I don't have a spreadsheet, but I know what carrots cost. They certainly haven't shot up by 50%.

I just saw this in real-time this past month with cat food.
A 24pk of Rx Renal cat food went from 5.8oz to 5.1oz[1]. I buy two packs at a time and what used to cost $113.76 is now $114.72
Effectively they're charging me an extra buck to keep 33.6oz (5.7 old-cans / 6.5 new-cans) of cat food from me.
