I don't think that food prices have gone up in the last 4 years, I know that it has.
There isn't anything in the store that hasn't gone up in the last 4 years.
I went shopping earlier this week the loaf of bread that I have bought for years is not $ 5.19. Last fall it was 4.59 and after looking on line to see what it was I seen it on my ledger for $3.79 in 2022.
Orange juice was 3.99. About 2 years ago it was 2 for $ 5.00 and that was the regular price not a sale price.
I worked in the restaurant industry and it was my job to be aware of prices.
Everything has gone up not one thing has gone down in cost in the last 4 years.
If you find it necessary to ask the question I question what cave have you been hiding in and when was the last time you went shopping
