I have been relying on the basic fact that pre-agricultural people did not have modern diseases. With that in mind, I stick to raw paleo and have no need to search for other therapies for the symptoms I used to have. I believe that ancient man was, by default, an instinctive eater - nobody had ideas of what a person should eat.
When I first joined this forum, I was obsessed with wanting to ask what to do. Eventually, I realized that the missing evidence was my own proof of RPD. I stopped asking and paid attention to what I was doing and how well it worked. I am going to hazard a guess that you already know the answer, or else why would you mention dairy? Experiment and see what happens.
Yes, regarding 'instinct', it is a revelation the day one starts to completely trust the inherent bodily intelligence.
It seems a step into dangerous insecurity, yet paradoxically, is liberating.
Yet, for what its worth, in my opinion, this 'surrender' is not an exercise in intellectuality, but rather one bumps one's head on a wall so many times, or one has a life threatening health concern, or something someone says triggers 'wheels in motion', or some other external happening, is a prompt to 'unlearning' things or things we have always deemed 'true'. And one is left standing naked in 'instinct'.
Not unlike this caterpillar emerging into the world:

As to asthma, dairy and oats, wheat and other grains caused me tremendous asthma problems earlier in my life. Banishing them from my life was hard, but was - and is - doable (if you find they are, or individually, contribute to the asthmatic condition)
