Thinking back to when I was growing up in Scotland in the 1940s and 50s, we had a very limited selection of vegetables. We always had potatoes and onions, carrots and some sort of cabbage. We sometimes had swede (which we called turnip or neeps), white turnip (which English folk call turnip), cauliflower, brussells sprouts, leeks, lettuce, beetroot and tomatoes in season. We had tinned peas (garden peas if you were posh, processed if you were not), baked beans and tinned or dried butter beans.
I sometimes think I should take my grandchildren to the supermarket and point out all the vegetables we never had - mushrooms, sweet peppers, courgettes, aubergines, butternut squash, spinach, green beans, kidney beans, asparagus, kale, beansprouts, sweetcorn, cucumber, broccoli, cherry tomatoes, garlic etc etc
They'd probably find it hard to believe. Our diet then involved eating meat (usually low quality gristly meat) almost every day at home and at school. I haven't eaten meat for almost thirty years.
