I would try making the coconut bread recipe but instead of using coconut flour, use Bob’s Red Mill oat bran. If the rash continues, then you’ll know it isn’t the coconut flour. But if the rash stops, then you’ll still have something filling to eat on the diet.
The Nutiva’s coconut flour that I bought, lists 3g of sugar in it. Just wondering if that is enough sugar to be concerned about. Perhaps the members who are effected by eating the coconut bread, also used flour containing this minute amount of sugar.
With Bob’s Red Mill oat bran, I didn’t see the phrase ‘gluten-free’ on the packaging label, like I saw on a package of Bob’s Red Mill Whole Grain Oat Flour (Gluten-Free). I called the company, and was told that oat products are naturally gluten-free. However, for those oat products that aren’t listed as gluten-free, they are usually contaminated with gluten either by growing near gluten grain crops, or by processing in a facility where gluten grains are milled on the same equipment as the oat grains.
