It is certainly a sensitive topic because the reaction tends to be that views like this "blame" the mother. It is not about blaming nobody. Our mothers had their own issues and most of them, did the best they could. But maybe it's worth to revisit our history, and see if our children are bringing something that was deeply buried, back to the surface, with the purpose of healing. Almost all parents love their children and want the best for them, but sometimes, because of multiple causes, this is a bit more complex.Â
I haven't done a serious research on the topic, but I talk to many friends and we see that our experiences were somewhat similar. Maybe the symptoms are different, since everybody does what we can with our issues. Some overeat, some don't, some become very strict. But the idea that we relate to food (source of nourishment and an opportunity to share) in a similiar way that we relate to our mothers (1st source of nourishment and the person we start sharing the word with) makes sense to me. Of course this is not literal, and is important not to fall in a simplistic view (my mom was cold so i overeat to feel warm). There are layers and each case  must be approached considering its singularity. But we don't come from a cabbage and looking into such a primary bond might shed some light. If the answer is not there, we can start looking somewhere else.
With any self-damaging behaviour, that is a symptom of a deeper issue, there is ussually a starting point. And when we start questioning  we realize that sometimes the "official story" is not the full story. It doesn't mean our mothers are bad people, it just shows that they are human, and carry their own baggage and brought their own baggage into the relationship. We have an opportunity to get off of a dynamic that is no longer functional.

I hope I make sense, and that is clear that i don't blame mothers of ED children. And looking into ourselves deeply, is always healing.
