That we can all relate to it and bond over it doesn't mean that all of us want to. If I feel like being social, fine. But most of the time I don't feel like being social. Often that's the case even when I want to relax and enjoy food - I'd say maybe 3/4 of the time I go to restaurants I go alone by choice.

But just like I can, and occasionally do, enjoy social interactions but usually prefer solitude, while I can, and do often, greatly enjoy food there are still plenty of time when hunger is just an annoying disruption.

All of the stuff that you have built up around food can exist just fine separate from it. You connecting socialising and bonding with food is just habit. That's fine, but it isn't universal.
