Was reading recently how in the US celiac disease is 4 times more prevalent and the rise seems to be in line with when the likes of Monsanto started to play around with wheat to ‘improve’ it commercially. This article explains what transgenic wheat is. There’s a lot to be said for avoiding processed foods full stop and putting in only what our bodies are designed for i.e. eating naturally. Do note that a lot of gluten free substitutes such as bread and pasta are heavily processed so I wouldn’t eat too much of that stuff.
