That's where my uncertainty comes from. I did the allergy immunotherapy for a few years, asked the Doc if they did anything like that for food allergies, and got the no, it doesn't work answer.
The reason is actually answered in the paper ;) There have been many studies looking at introducing peanut allergens in small increasing doses over time. this does somewhat work but the effects ware off pretty quickly after stopping. The 'secret sauce' in this study is the use of the specific bacteria which somehow teaches the body to retain the non-immune response.
