I can eat warm meals when appropriate, in company, etc. I do live alone now though so am afforded more choice.
I don't subscribe to any diet or exclusions, just my personal preference, and it isn't 100% of the time (I like cooked noodles and occasional soups).
But most of what I prefer is cold, such as salads, homemade flatbread, fruit, fish, turkey, etc. A typical day might involve me eating:
Flatbread with a decent peanut butter & jam, tuna salad with cucumber, radish, onion, spinach, rocket, tomato, herbs, avo, olives. I roast dry my own tomatoes and then jar them in oil and herbs - cold!
Dinners include similar with a cold potato salad, egg, etc, or Tapas style variations on slightly toasted bread. I do get a whole range of veg and fruits (love berries with either yoghurt or banana for supper) but do prefer meats to be cold.
Will often have a day or two per week where I grill a homemade veggie pizza topping with mozzarella, or have poached egg with avocado and cress, but it is largely cold over all. I drink milk but only in tea.
I know i can eat how I want, but I can't find much info about this particular preference online apart from raw foodies (no help) to exclusionary diets. I take a multi vitamin, so hope I am getting enough of what I need. It is the only method which calms my IBS, so large or hot meals seem to aggravate it. If there's something glaring missing I would love some pointers.
