I listened to this again,
So\ much info and alot that relates to SCD/GAPS/Paleo/PHD or any dietary interventions (juicing, vegetarian etc)
Probably the best talk explainingthe reasoning behind testing and reintroduction of foods i've ever heard (but it will take a few listenings to get it all), so if you are going to try a diet you need to understand that everybody will react to different fodmaps (and other food elements like protiens) to different degrees at different times.
SO...... testing foods to see if you should eat it (or how much of it you should eat) seems to be a vital and misunderstood part of dietary techniques.
