"This study just came out suggesting that changes in gut flora can happen very quickly in response to diet changes. The study is looking at plant-based vs. meat & dairy diets, but seems like it could apply to other diet changes too. This isn't directly about rosacea, but I'm thinking it could maybe point in the direction of a better understanding of how some of the food triggers work. http://www.scientificamerican.com/ar...e-changes-diet "
