Some 12 years or so ago, I developed acid reflux disease and then a couple of patches of skin rash on my ankles and my hips.
I controlled the acid reflux with acid blockers, but got to the point where I could not afford to go a single day without taking them.
I tried everything I could find for the rash. About the only thing that helped was diaper rash medicine.
Some 7 years ago, my dad was diagnosed with Coeliac (Celiac) disease. Gluten intolerance. Celiac Sprue
Thinking that I might also have inherited the condition, I quit eating foods containing gluten. The acid reflux went away. As did the rash.
I just found a link (pdf) between the rise of gluten intolerance and the use of glyphosate. Damn it.
