Mine is quite high, its nearly all fresh fruit and veg so about 80% along with some pulses and milk eggs etc. We are a vegetarian household so it makes sense that we do buy more veg and as vegetarian ready meals and convenience foods typically suck we make our own food from scratch daily to ensure we have something tasty.
Met a colleague in the supermarket today who commented on the "crazy" amounts of fresh veg we had (which will only do us 3 days until our delivery comes). Her trolley has some potatoes and an onion in and everything else was in a packet or box. I previously hadn't noticed how much fresh produce we had compared to other shoppers but as I went to the till it did look like most people had very little veg in their shopping (the produce section is at the entrance and most people would pass through that section first).
However the produce section is well stocked and has all sorts in cavolo nero, celeriac, fresh herbs, ginger, aubergines so people are buying it.
So I am just curious how much of your trolley is fresh fruit and veg?
