I'm just curious. Is it normal for households to regularly throw out food? I am NOT at all wasteful, in fact I eat expired food

I know people that absolutely won't eat anything past expiration, but then, even if we try our best not to throw out anything, it still happens a lot.
I inspected our ref and I feel so bad because I had to throw out a whole cake (one slice lang nabawas), a llanera of leche flan (untouched) and a big bowl of soup. If I think about my cousins in the US, I don't feel too wasteful kasi mas malakas sila magtapon, like for example they would open a can of soda, take a few sips and leave or throw it out na. Anyway, parati ako napapagalitan ng Mommy ko for wasting food but it's not like she does not let food spoil too

So I wanna know how normal is it to throw out food and clear the ref (and find a lot of food to dispose)
