This post is very good @macchiata, because you make a sincere reflection on what food should be. It seems good to me that you find your own path and do not follow the standards and fashions that are often imposed. It is also very positive that you do not exclude some foods from your diet, just because some study or trend says so. I think that the emotional and mental areas also greatly influence the link of diet on human health, so being calm, without pressure and at your own pace, is great and very beneficial for you.
By the way, those brownies are delicious, very good recipe.
