Sure, here's my preferences:
spicy foods I enjoy moderate spice. Really really spicy is a bit much for me, and I do tend to drink a lot of water when eating spicy foods, but I like them.
sweet things Definitely have a bit of a sweet tooth: I enjoy these and would generally prefer to have a dessert over a starter in a 2-course meal, for example. I like chocolate but I'm not sure that's a particularly great example for this category, as I also enjoy it in its less sweet forms: very dark chocolate, unsweetened drinking chocolate. It is also definitely possible for things to be too sweet for me to want them in large quantities.
alcohol Don't like, don't consume to any significant extent.
drinks I drink a lot of water and no-added-sugar orange squash (I think this is quite a British thing: it's similar to a cordial but somehow different. Comes in concentrated form and you add water to make the drink up). Juice (usually orange) sometimes; milk occasionally. I like lemonade but tend to reserve it for pubs or eating out, neither of which I do all that frequently. Don't like ice in my lemonade!
hot drinks Until a few months ago, I drank a fair bit of tea but decided the caffeine was bothering me, so now I drink tea (with milk but no sugar) a couple of times a week and most days have either rooibos or some herbal tea like peppermint or chamomile. Hot chocolate or chocolate Ovaltine quite often. Coffee extremely occasionally (like once or twice a year maybe).
bitter foods Mostly like. I really enjoy olives and vegetables that some people describe as bitter like broccoli or sprouts.
excluded vegetables Can't think of any really... I used to be not that fond of parsnips but seem to have got over that. Fruit and vegetable preferences for me are a lot more about texture than taste, so sometimes a vegetable that I really like when I cook it can be a bit off-putting to me when cooked in a form I'm not keen on. I'll probably still eat it though. Oh, water chestnuts, I don't like those. (Are they a vegetable?)
animal based products Haven't eaten meat for years so can't comment on preferences. I like and consume quite a lot of dairy and eggs in various forms, including goats' and sheep's cheese which no one else in my family can stand on account of the baffling complaint that "it smells like a goat/sheep".
tofu or other replacement-animal-products I probably eat less of these than many vegetarians, although I have no objection to any of them that I've tried. I just prefer vegetables and legumes and so on, I guess. Tofu is the most often used in my cooking (maybe once a week or slightly less).
sour I quite like citrus flavours, but in relatively small doses I suppose. Sour fruits are fine modulo texture. I like grapefruit, for example. It takes me quite a long time to consume this type of thing if it's in concentrated form, as I find it to be a very strong taste (a small glass of orange or grapefruit juice can last me ages, for instance).
vinegar No objection, don't use it that much.
starchy foods I like bread a lot, fresh from the bakery (or our own oven) being the best kind pretty much regardless of what sort of bread it is. Also eat pasta, rice and potato very regularly. Not much preference between these really, although I find I eat less if I'm eating potato: it seems more intense and filling.
salty foods I think I have quite a low tolerance for salt. I don't add it to many things when cooking and often find processed (or even just not-made-by-me) soups etc to be overwhelmingly salty. I seldom add it at the table, steamed cabbage being an exception that I feel benefits from a bit of salt.
Following on from:
I would like to ask for other people's experience of flavours. I am dividing food into significant categories that I can think of. I don't really like the 5 tastes categories for this task, but I am aware of them. This post is meant to be about taste preference although it might end up about dietary preferences.
My experience:
I dislike spicy things. Chilli, Curry, too much pepper, horseraddish; are all not nice things. I do eat wasabi but I like that the flavour goes away unlike chilli which continues to burn. I do eat like sweet chilli.
I am completely and uselessly over-addicted to sugar. Nearly every food I eat is sugar-based. I have no problem with savoury food; but I would completely prefer to eat sweet things to savoury. I like chocolate. (I tend to cook a lot and end up with sugar in a lot of the foods I cook - and they taste delicious)
Drinks: 95% of what I drink is water; I drink soy milk as a drink (about once a week), I don't mind milk but don't drink it much. I drink apple juice (and previously accidentally conditioned my brain to treat it like coffee-wakeup so am trying to maintain my conditioning and not drink it too often). I dislike processed orange juice for its bitterness, however enjoy fresh orange juice (I realise that some people cannot taste the difference so you might have to trust me). I rarely drink cordial and rarely drink soft drink.
Hot drinks: I don't drink coffee, I rarely drink tea (less than once a month, and coincidentally only with other people, not for myself as I might drink or eat other foods), and when I do; drink it with several sugars (upwards of 2-3). I do drink hot chocolate but rarer than tea.
I dislike the taste of alcohol, anything from beer; wine; spirits. The only alcohols I can happily drink is an uncommon lychee liqueur and the alcohol Bitters (I am not sure if its actually meant to be bitter but) I don't find bitter and will drink it happily, Bitters is usually a ^40% and meant to be used as a dash (as in "lemon lime and bitters"), I can happily drink 4x or more in a drink. Tequila will make me throw up most of the time.
I dislike bitter foods; Olives, coffee, several of the vegetables listed below.
Vegetables I don't eat: bussel sprouts, asparagus, squash, any lettuce other than iceberg, string-beans, artichoke. They have never tasted nice to me. Bok Choy was a vegetable that I did not eat; but now do. Although it can be not-nice tasting if cooked in a way I don't like.
animal base products: I eat meat, fish, cheese, honey and like the taste of all of them quite a lot. I have tried many tofu, false-meat and other substitutes and also find them to taste nice.
I eat a lot of cheese ~1-2kg per week. I eat peanut butter from the jar.
Sour: I don't like sour foods as much as some people I know. (I know someone who eats citric acid almost by the spoonful)
vinegar: I like vinegar.
Starch foods; potato, bread, rice, oat, pasta, corn. I don't mind any of these and eat them equal with their ease and availability with the exception of not liking the annoyance of eating corn; although I am completely happy with the flavour. I don't like the taste of any bread that isn't white bread (bread with seeds or brown bread or sourdough is not appealing to me)
salty foods: I don't have much preference of salty food. (I knew someone who was eating salt almost by the spoonful)
