At some point I have to unpack and describe the specific intersection of factors that led to my specific experiences with food shaming (and all related topics like sizeism, ableism, neurobigotry, healthism, ageism, etc).
As a a fat, autistic, ARFID-ite who's consistently been treated as younger than I am, and with scandalously non-abusive parents (how dare they vaguely accept me as I am without beating me into submission!), a lot of the food shaming I've experienced in my life was based on treating me more as a "spoiled child" than as a "fat woman," even after I was clearly the latter.
Food with my extended family or parents' friends or anyone older than myself was always a site of shaming how spoiled I was, how overly permissive my parents were, how rude I was for not eating what I was served (specifically for that -- I wasn't actually doing any "rude things" like commenting negatively on the food, demanding alternate food, or anything like that! But simply not eating what I was served, as a Young Person, was "rude".)
I was also heavily desexualized and somewhat degendered, so it wasn't "You're an unsexy woman because you're fat and ugly, not thin and sexy like a woman should be," it was "You're a spoiled brat picky eater who needs a spanking." Up through age. Like. 24.
And I realize, please believe me, I am very well aware of what an incredibly privileged problem this is. I was sigmatized because my parents weren't abusive? What kind of problem is that? Everyone else was dealing with actual problems, like actual abusive parents!
So my point isn't to complain about my problems, it's to say that food-shaming takes many forms. I was reminded of that when I saw an otherwise good, innocuous post about getting along with family at Thanksgiving, that included something about "Don't ask teens if they have a boyfriend/girlfriend, ask them about their hobbies, or what they're most looking forward to on their plate!" and I was suddenly filled with anxiety, because, no, don't do that. If you had asked Teenage Me what I was most looking forward to on my plate, I would have assumed that you were admonishing me for only having two foods on it, lecture me about how I can't have dessert if I don't eat my vegetables, nagging me to "Just try it," and possibly throwing in some remark about "Back in my day, if we didn't eat what we were told, we got a whipping!"
Questions about my nonexistent love life would have been comparatively less fraught.
Don't comment on people's food choices. Don't comment on kids' food choices. Don't comment on teens' food choices. Don't comment on adults' food choices. Don't comment on people's food choices.
Don't ask teens if they have a boyfriend/girlfriend either, although, if that tradition must continue, I'd at least like to add age balance to it. If you ask a 15 year old if she has a boyfriend, she should legally be allowed to ask you how your divorce is coming.
