If you really like your fruit and vegetables, you don't buy them from a supermarket here. We do have some supermarkets in Cairo, but their produce usually isn't so super. The smaller corner fruit sellers have fresher produce by far. Other than out of season fruits (like grapes in winter or apples any time other than mid summer) most of the produce is grown here so it is indeed fresh. One of the things that I love about Egypt is the fact that the things that are good for you are cheap to buy, while the things that aren't so good for you like Oreos or Cheetos or chocolate bars are more expensive. I think that is the way things should be.
