I am someone who at this stage in life seems to have^ an issue with gluten.
Lots of people aren't like me though, and for them I do not believe there is any particularly well documented issues when it comes to gluten.
^Where 'seems to have' is self-produced anecdata: I spend months working through food group diet permutations (starting with removing basically except lightly cooked vegetables, miso soup and congee :-/) in an attempt to zero in on what was causing near-permanent (~10am->sleeping) acid reflux I had developed. Conclusions point fairly strongly to gluten, which I now mostly stay away from (I still eat it occasionally, zomg burgers, I just make sure breads/pasta/etc isn't the base of my diet).
