If people made such a huge deal about the nuances in the taste of bread, while it also "happened" to have psychoactive effects that, gosh, always have to be present for the bread to be "good enough" for them, and cheap breads were still normally several times the cost of comparable-nutrition food, then yes, the cases would be parallel.

(Before anyone says it: Yes, I know bread as trace quantities of alcohol, we're all proud of what you learned in chemistry.)
