This post, about the lack of evidence supporting the purported benefits of gluten free diets, got me wondering about historic examples of similar 'healthy eating trends.'
For example, weren't the Romans pretty turned off by the Germanic use of lard (as food and hair product), and/but could we consider their stance similar to the gluten free diets of today?
By the way gluten free isn't a fad diet. That's like calling lactose intolerance a fad diet. A huge majority of people who stay off gluten do so due to intolerance
