Why would it taint a family relationship? It isn't just gluten, lots of people are taking pot shots at the same big target. Out bodies weren't designed for processed foods or even grains. That's a relatively new addition to man's diet. Most of us can tolerate them but overuse will cause problems.
Thanksgiving dinners with family, for instance, were a relative takes hours cooking only to have me pick through it, and it bothers them, like some posters here think this is a made up fraud. I understand that, I can't eat grandma's old recipes loaded with wheat gluten as a binding agent. Pastas, Bread, you name it. Cereals.Anything involving wheat gluten protein. A lot of you people have unexplained stomach problems that I think point to gluten sensitivity, and should have it looked into. It is real as death.
