If you went back to the original hunter gather foods, you would still have people allergic to nuts for instance. I think we simply see more of it nowadays because medicine is better at saving these people when they do go into anaphyalatic shock and they survive to adulthood to pass on the allergies to their offspring - something natural selection 'dealt' with before.
This is one part of what I'm talking about. Natural selection simply doesn't work as well as it used to due to medicine. But it's not just medicine, it's living inside in (over) heater buildings which in turn makes us less resistant to cold and therefore everyone gets sick the moment they put their nose out during the winter. It's like you mentioned water quality, most people drink water from a bottle for all their lives and then claim that the tap water is bad because they got sick when they drank it etc. Same with overusing medication, we have medication and vaccinations which are used against such things as the common cold. And then we wonder why our natural resistance is lower than what it used to be.
As for allergies I found this graph. Do note that it's just for children between 0 and 17 years. Taken from CDC website:
The change is a lot smaller than I thought but I think we can all agree that it's going in the wrong direction.
