I have to be very careful about wheat products. If I eat the wrong stuff, I get acid reflux, and nasty acne. Some people tell me that I'm allergic to gluten. Others say yeast, because it's mainly crackers and noodles that I can eat. But not all wheat crackers are OK. The only one that I'm sure of is Stoned Wheat Thins, from Canada.
I wonder if it's glyphosate, or some other pesticide.
