This is a tricky question and while I don't have any specific answers to the question at hand, I'd like to make a blanket statement in the same general category of thought.

While most of us like the idea that our body will "let us know" what it needs, I think that more often than not our sensations/intuitions/reactions are artifacts of radically different environment and ecology (both macro and micro).

We essentially "fly by wire" and are, in a very literal sense, incapable of perceiving the world directly.

All of our senses take in as much information as they are capable of, and our brain then interprets the results. Our consciousness is then fed the interpretation in the form of what we see, hear, feel, smell, and taste.

This isn't to say that our body CAN'T give us useful information, but I do encourage discretion in how far we depend on body sensation as a reliable index of cause and effect.

This notion can be uncomfortable as our illusory concept of "reality" is very convincing, but there various ways that we can remind ourselves that this is in fact the case.

For example...

"In this illusion, the coloured regions appear rather different, roughly orange and brown. In fact they are the same colour, and in identical immediate surrounds, but the brain changes its assumption about colour due to the global interpretation of the surrounding image. Also, the white tiles that are shadowed are the same colour as the grey tiles outside the shadow."
