As far as I recall the average diet has changed tremendously
this was north east - I know the richer south progressed more quickly
no takeaways , no eating out. Fish and chips once or twice a year.
no UPF / all natural food apart from bacon. Yogurt from the early 80s? Similarly frozen pizza. About hand sized.
water with every meal
no “fancy” food - plain meat and potatoes and gravy . Or potatoes and plain fish. Not chilli’s , curry, bolognaise, pasta with sauce. pepper was the only spice. It wasn’t a vegetable. Veg was just boiled. Never cooked in any kind of recipe.
. Bread and jam. Bread and butter. Carbs based
seasonal British vegetables - only frozen peas. Carrots and cabbage in the winter, lettuce and tomatoes and cucumber in the summer. On repeat. Potatoes - jackets, boiled, mash, chip, roast , repeat. The diversity today is amazing.
portion sizes - we used a 4ox flour, 4oz sugar 4oz butter and 2 eggs recipe to make enough cake for the week . with my family it was 8,5,5,3 to make a cake for the week.
you might be always hungry but food was expensive.
treats - 4oz of sweets on a Friday. And a bag of crisps on the Saturday. Not daily .
