As a young child I disliked most savoury food and wanted nothing but desserts and sweets. Every time my father complimented my mother's cooking I would contradict him. My bluntness was probably down to ASD, though as my parents were routinely blunt when not in unfamiliar company, they probably also taught me to do that by example. I did comply and eat the food I disliked, with only moderate resistance. I guess a strong preference for sweet food is pretty normal for young children. The only food I had really big issues about were fish roes, which most people probably find pretty disgusting anyway, and my sister also hated those, and my mother had to give up on them after a few weeks because of our resistance. I even accepted a daily spoonful of cod liver oil when I was very young.
As time went by I developed a liking for savoury food, and stopped whinging. As a young adult I was keen to try new foods, with some kind of ideological preferences such as disliking a lot of the food my girlfriend's mother gave me (she would do silly old-fashioned things such as adding bicarbonate to the greens to make them greener, and that also made them too mushy for my taste, and I'd read that it destroys the vitamin C). So my preference was for the less traditional cuisine, though I was fairly omniverous, and rarely refused anything or made a fuss. Nobody seemed to think I was a picky eater. The one thing I recall that set me apart was raw onions, chillies, any kind of curry that wasn't very mild. My girlfriend and our peers were often quite into those things, while I rapidly discovered that I hate them. I still have trouble understanding why a huge swathe of people like to eat anything that hurts their mouth.
I gradually became more health-conscious with food, and started rejecting more and more conventionally-accepted things, but I was rarely rigid about it when faced with social pressure. These days I'm more rigid and as I've discovered more about the food industry, the ethical problems with meat, and healthy eating, there are a lot of things I don't normally eat any more, and I've only been to MacDonalds once in the last decade (and hardly ever before that), and that was because I was new to the place I was living and didn't want to seem too aloof. Even then I think I only had a cup of tea or something. I remember looking online for acceptable MacDonalds food and finding almost nothing.
So I don't think I have what could rightly be called food issues. Most of my friends in the UK are vegetarians and vegans, and they don't much like junk food or politically-questionable food outlets, so there's little or no problem. In the Arkansas countryside it's often rather different.
I'm not hypo-sensitive to food. I'm discerning about what tastes good to me and what doesn't, and it's fairly important to me that I enjoy my food generally, but I'm not violently opposed to making an exception now and then to avoid hurting people's feelings, as long as it's not too big a step down.
