Is just to avoid processed food. Eat tons of fruits and vegetables. As a side benefit, it looks likes there is a connection between allergic sensitivity and the gut flora, which will be built up over time by lots of fruits and vegetables (as long as you avoid soda and other acids). So you may even see a decrease in sensitivity. For years I could not figure out why my allergies seemed to get better or worse for no reason, but it was my produce intake.
