Liz, when we say human foods we meant foods cooked for humans only, table foods as in those meant for humans dinner and 99% of those are salted. There are lists of good fruit, veg, grains, beans, etc. so any normal person will figure out that if they have that cooked without salt, fat, etc. it will be good for the parrots too, but they won't feel like sharing their spaghetti bolognese, curry, pasta bake or any of those foods with their birds.
Again, let's stick to the safest versions of the advice on here and if any members have additional questions we can always go in more detail for specific foods, etc.
