teddy, of course I can imagine being hurt by something a parent said, but blaming it on food issues twenty years later is indulgent and ridiculous. Your issues are yours: they may have stemmed from somewhere but there comes a point where 'get over yourself' (meant kindly) has to apply.
I was raised in a very middle class family who unintentionally prevented me fitting in anywhere, for a plethora of reasons. Church was one - they sent us to Sunday school to get rid of us, I think 
(I think mum was a little depressed) but we had to march through the streets of our small town with tambourines singing What A Friend We Have In Jesus. My brother suffered more for that than I did - he was absolutely crucified for that for many years (pardon the pun.) Then there were the clothes. Oh my, the clothes. Mum had horrible taste anyway but my wardrobe was entirely made up of the garish, too short and too tight. I'll add here I wanted to wear them as they were the cast offs of some older girls I idolised but I look back at photos in horror. My mum died when I was very young and sadly it isn't an exaggeration to say I don't have one nice photo of us together. I really do look at them and think WTF were you thinking? My brother has ASD (undiagnosed) and used to insist on wearing massive clothes - he looked like a homeless person.
I could sit up all night and talk about the hundred ways we didn't fit in. The really sad part was as soon as my mum died and I had a part time job and could afford nice clothes and a haircut, I fit like a glove. I just regret that I attracted so much negative attention as a child and younger teenager because I looked scruffy and silly.
When I had my children, I knew I wasn't ever going to have them feel like that. Sometimes that means bending your principles. My eldest has an iPhone and that's reluctantly, on my part, but I don't want him left out of the 'gang'. But they are clean, tidy and with neat hair. They dress conventionally. They have the correct school uniform (well, my school age child does).
I know I will get jumped on now by people saying their children do too. Of course they do: teddy's boys looked very well cared for - BUT, my children would NOT leave the house like that.
My example above is an extreme one but lack of awareness about others and how they react to children is worrying. As I said in a PP it reminds me of door slamming and 'What? What?' People will notice, laugh, jeer and point. If that doesn't bother you (though it does, hence the thread) I can state firmly it will bother your child.
