Trying not to be overly broad with this question, I will attempt to pull out some specific items here that I would find helpful:
I tend to have very active digestion for most of my life (read: I seem to go to the bathroom more than most. 3 - 4 movements a day is typical), along with some definite food sensitivities. We have ruled out celiac via bloodwork, but generally the diagnosis doesn’t go much beyond “you probably have some form of IBS” and to watch what I eat. I haven’t had much success with elimination diets and the like, but I occasionally connect the dots and can figure out something is a trigger. For example: garlic and onions are unfortunately out, and just recently it seems like brown rice is another trigger food. Other items that tend to cause problems for others such as dairy seem to be just fine for me.
With regard to nutrition, tracking macros and such, are there adjustments to be made in terms of intake? Higher or lower amounts of specific nutrients?
I have read a bit about the possibility that IBS could affect nutrient absorption, but I don’t pretend to know if the information is conclusive or studied well. As far as you know is there any evidence of this and is it possible someone would need to up intake of macros or calories in general if some of what gets eaten is just passing through?
I guess the question all stems from - particularly if I am having an episode for a day or two - are there inefficiencies in how my body is absorbing food that I should be aware of and account for?
I am 38 y/o and I think I respond to strength training pretty well for someone with my age and experience, but have always been on the leaner side and struggled putting on mass, and this feeling that food just kind of runs through my body always lives in the back of my head. Thanks for any input!
