This comment doesn't really fit to the post, but kind of, as it also leads to my depression and anxiety.
I am scared of sugar and avoid eating anything which contains it. I'm also not very "excited" about natural sweeteners like honey, agave sirup and so on, but my main problem is the "real" sugar, which is part of the usual sweets. I know, I know, there is not such a thing as good or bad food and in the end it's all just energy for my body. But I've got that feeling/fear, that my body gets kind of angry (haha), unhealthy and poisoned, when I eat just a little amount of sugar. I really prefer eating whole and clean foods, even if I know that it's not good to get obsessed about eating completely healthy. For the body maybe it would be if I get enough nutrients and so on, but for the mind.. well, certainly not. I think what I really need is a valid and scientific explanation why it is NOT bad, unhealthy, poisonous, ... for my body to eat sugar (and in general "unclean" food), because mostly we get explained in a detailed way why it is! Can you try to give such an explanation or a comment about it? Your opinion always really matters to me, as you have got a whole lot of experience and knowledge (due to your studies) as well! (-:
