Stool color change with what you eat?

[NickG]

Good afternoon,

This is my first time posting here so I apologize if this has been discussed prior. I’ve been diagnosed with celiac  disease for a few years now and every so often I’ll get a cramping feeling under my right rib cage. Wanted to see if this is a common sign of cross contamination? 
 

the second item is that this week I’ve had very dark stools and think this may be due to eating a pasta salad that had very dark balsamic vinaigrette included? I’ll notice the stool color change even with drinking a purple Gatorade and feel as though the lining of my bowels have been stripped from all the years of gluten abuse. Does anyone else have these symptoms?

any info would be greatly appreciated!

Welcome, NickG!

Concerning the pain under your right rib cage, have you had your gall bladder checked?

It is pretty normal for stools to turn dark when eating foods high in black, red, or purple pigments. I don't use Gatoraid so I can't comment on that in particular. But I do see it with things like beets, leafy green vegetables and blueberries.

It's always a good idea to double check your diet just in case you might be getting hidden gluten:
