I don't feel any emotional attachment to food at all; to me, food is just food. I do like the taste of it and enjoy eating it, but I don't think there's anything wrong with that. The bible clearly states that GOD created enjoyable things and beautiful things and food for our pleasure.
I have NEVER put food before GOD!!! I think SATAN uses food as way to make us feel bad though; as a way to put us down, and fill us with guilt ... and some people (like the Romans) use to eat food as an activity in itself (warning: gross graphic language ahead).
They would prepare massive feasts of food, then spend days eating and drinking in excess, and not only that ... they had huge spitoons (now adays used for other purposes equally gross) situated behind curtains; and they would go there and regurgitate

the food up; wash up and return for another fill. I believe this is just one of the things that Paul was referring to; as well as eating feasts for the Lord's supper, which was suppose to be a holy event.
Each person is different; and each person will interpet these things for themselves. Today, we live in a society of abundance and I saw a verse once in the old testament that said something like this, "their abundance of food became a snare to them." That was answered prayer for me as I had asked GOD about this issue just before finding it by accident (really the Holy Spirit likely made it stand out for me as an answer to my queries).
So ... I feel we are giving food just way too much power; many of us never learned to eat in moderation (another thing Paul talked about
: let your moderation be known to all men). I know we were extremely poor as children and didn't have access to the abundance we have today; when we did, we were like kiddies in a candy store and ate too much until one day my mother and my doctor explained to us that this wasn't healthy for us.
Moreover, our human nature (sinful and flawed nature) tends to want to do things in excess sometimes (ie alcohol, food, etc); I have prayed about the gift that the Holy Spirit offers us, which is the gift of DISCIPLINE. I am working on that one right now. I am trying to teach myself techniques to limit the foods that tend to get us to munch (for me, that's salty & crunchy ones and cookies). I don't have cookies now becuz of this, until I learn how to eat them in moderation; and if that doesn't happen, I will not buy them. I now look for single servings of these things and will have them now and then only.
Sorry, I don't mean to ramble, but for me -- I think DEPRIVATION (dieting)had something to do with this. We never had these things when we were younger and now that we do, we have to learn how to eat them in moderation or skip them altogether. I am learning to enjoy healthier foods; and I also buy healthier foods now too. For me, this is a learning process. The DIETING I did in the past was too restrictive, now I am using a much more balanced and healthy eating plan. I now allow myself some treats, in moderation, and in small quantities ... yes, it's a process!
To answer your question about food as an idol -- I think that some foods have an addictive quality and I think it's the excesssive SUGAR & SALT in them that is causing this, not any emotional attachments. I think this is a totally physical reaction by our bodies; and it is noticeable that this runs in my family; which shows a heredity element to the problem. I have heard doctors say that the excess salt & sugar & fats are added to make them addictive so that you will want more ... it's marketing food science!
My husband can eat anything, and I mean anything; and has no issues with food. He doesn't analyse what he eats; he just eats whatever he wants, when he is hungry, but he eats often and in small amounts. On occasion, there are some things he too will eat too many of (like chocolate balls and sticks, and baked goodies); but because he has a fast metabolism and is very active, he burns it off ...
When someone brings up something upsetting to me and I am eating; I now will put it down and go away until it has passed. I believe that is what I call mindless, stress-eating; and this was taught to me as a coping mechanism by my mother who did the same. I am now more conscious of this than ever before and now I can take measures to stop it -- plus like WILLOW, I also believe in the GIFT OF GRACE!
Again, sorry for rambling ... I hope there's some food for thought here!
