This 100% doesn't affect most food. I grew up in Israel, where things being Kosher is the norm rather than the exception. Although the central Rabbinate covers most kosher foods, the more orthodox will often defer to the authority of particular rabbis and buy from a smaller set of products than all of what is nominally kosher. In my experience, they often tended towards the lower quality end of the spectrum. When you're dealing with a product that has only a few ingredients like matzah, any increase in attention will have a positive overall effect. In more complex processed foods, when your emphasis is on meeting various kashrut guidelines the flavor of the food becomes secondary. Not only that, you know that you have a captive market. So, this is a fun story, but should really have s/food/matzah/ Applied to the headline.
