It seems one of the philosophies behind a grain-free primal diet is the idea that we all have some degree of sensitivity to wheat, even if we have no full blown wheat or gluten allergy. But what if you have been tested for wheat sensitivity and it came out negative? Is there still really a significant advantage to avoiding it altogether? I agree all white flour products should be avoided by everyone just because "bad" carbs cause all sorts of health issues from high triglycerides to diabetes. But if if you have no wheat sensitivity is there really any reason to avoid the healthier forms of wheat, such as a slice of organic whole grain bread?
