I have a “gluten intolerant” family member, who has discovered by accident that Indian flour, at least the flour used in nan, doesn’t cause any of the gastric problems associated with North American bread and wheat. Could it be an intolerance to glyphosate used to finish the wheat instead? We certainly suspect so! Shades of an industry that at one point in the 1990s suggested putting statins in drinking water and has exposed us to way too much fluoride for decades.
