Why do some people bring grieving people food?

Ever since my grandpa died Last Tuesday, I’ve been getting phone calls, people have been coming over which I do appreciate and some people been giving me food. I mean I appreciate it but I wish they would stop! I don’t understand why people bring food when someone dies? It’s not like I’m going to be anorexic. My older cousin asked me a blunt and rude question “How much do you weigh now?” Really that’s a rude question to ask. I told her I wasn’t thinking about that and that’s so rude!
I need to be alone, people won’t stop coming over and I need to be alone to grieve and I don’t wanna eat. I’ve been getting rude comments on here that I’m not appreciative. I am it’s just that I need space. My family kept bugging me that we they don’t want me getting skinny or anorexic since my body isn’t built for it.
