I read "do you eat 30 different fruit / veg in a week", and I started out curious if we even HAD 30 to pick from. We don't all eat all items, and certainly not all within a week; of the 36+ core items it's unlikely any individual one of us would go over 20 on a given week. How many do you have and actually use?
This is what we have; occasional other bits like figs I don't buy enough to count, I think this is the main set:
13? Fridge: olives, cherry tomatoes, potatoes, iceberg lettuce, artichokes, romaine lettuce, rocket, baby courgette, mixed peppers, fresh chillies, ginger, garlic, baby leek, red onion, spring onion, coleslaw, kimchi, some M&S mixed salad packs (assume we won't count garlic and random pack mixes)
3 Fruit: apples, clementines, raisins
3 Freezer fruit (only for pancakes): blueberries, raspberries, strawberries
3 Freezer veg: cauliflower rice, sprouts, mushrooms garlic, ginger, chillies, mixed greens thing, packs of chopped leek/ courgette / onion / aubergine (from when we were going away)
5 Fruit juices: apple, raspberry, pineapple, rhubarb, grapefruit.
10? Cupboard (used a lot but removing lots of duplicates): peanut butter, almond butter, cashew butter, almonds, cashews, seeds (sunflower, pumpkin, chia, sesame, black sesame, mixed), beans (baked, black, pinto, butter, kidney), water chestnut, bamboo, grated coconut, tinned tomato, tomato paste, mixed grains, artichokes
0 Cupboard (so rarely used): pistachio butter, pearl barley, hearts of palm, poppy seeds, lentils of various types (not counted as not eaten often), walnuts.
