I'm in Europe. I have been tracking my all expenses to the cent religiously since 2010 in Excel sheets. I also haven't changed my grocery habits much since around 2020, except very recently when I actually started looking at the deals (discounts) and buying more generic stuff. We haven't been eating out much (~5 times per month on average) Obviously, it varies month-by-month but my family's (2 adults, not counting the child) expenses on food have risen by around 100% since 2022.
