One really clear indication of many longer FB users situations is likely to be energy bills. The biggest part of mine from pandemic onward, are standing charges and VAT, not actual energy use. The money goes on keeping service on, not using them.
Over time, bag contents requests can tell you a lot about people's situations, especially if you run a x items from this list, and y, and z from these others, system.
I had to turn down anything requiring more than a kettle or very lightly one ring heating, so my bag (vegetarian) was things like dried noodles, Bulgar wheat, easy cook pasta, tinned beans, tinned veg, tinned/packet soup, powdered mash, and cold food. (eight items max weekly)
Any available veg/fruit that could be eaten raw or kettle cooked.
Always pasta never rice? - May be personal taste but generally safer to cook more with same power usage, then eat cold for days because fridge turned off/ non existent.
Wants tinned chick peas, tinned lentils, tinned plain beans, will give left eye for rarities like tinned macaroni cheese, ratatouille, tahini? But never any dried versions, or many 'nice' veg? = can't afford to cook them.
Never jam, biscuits, bread, cake, other luxuries? (even when allowed two from this list weekly) = Managing health condition
Never baked beans, and spaghetti in tomato sauce - Managing health condition (or just taste.)
Never flour? Health condition/can't afford to cook with it other than stirred in to soup etc as a thickener.
Swapping out food for additional loo rolls, cleaning products etc? (two from household list weekly) - Managing illness.
