<<Disclaimer: Verify this information before applying it to your situation.>> Well, folks, here's a new question - or one that I have not seen addressed on this LIST. At age 40, I was a student at the University of Minnesota, and because of my (then) "advanced" age, the school insisted on a complete physical. Much to my surprise, the opthamologist told me I was red-green color deficient. That does not mean I can't see traffic lights, and it does not mean I don't see colors, it just means that there are some degrees of colors in the red and green areas that I do not see the same way other people do. I told my parents, and it turned out that my father, who was also sensitive to gluten, was also red/green deficient, although he was not aware of it until age 78. My gluten/sensitive son is also color deficient. This past weekend we entertained a diabetes expert as a house guest, and while doing an antique, wooden, jigsaw puzzle together she talked about looking for color matches. I said I couldn't trust my color eye, due to that red/green deficiency. "Amazing," said she. "I only have one other friend who is gluten sensitive. He is a doctor in Washington, DC, and he is also red/green deficient." So my question to all of you is, do any of you know that you are color deficient in any way, and is this a problem that is carried on the same gene as celiac disease? Just musing.... Gayle Kennedy
