I have just finished listening to “The Gluten Summit.” This is a wonderful series of talks. In Dr. Davis’ talk he mentioned that people who, after following the recommended diet and do not improve the results of their NMR tests, can have a ApoE 4 gene. People with this gene have to limit intake of all fats – even the good fats. After I was on the diet recommended, all my blood levels improved except for this test – it got worse. I had been eating good fats which was recommended. The doctor could not tell me why this test got worse. I would like to ask my doctor to do this test on me. Do I ask him to do an “ApoE gene test.” Can I expect he will know what I am asking for?
