Are Christians allowed to eat on Good Friday?

Completely depends your age, how strict you/your family/your congregation follow the rules, your church, and even your denomination.

Catholics, for example, have the rule that Du are supposed to fast completely on Good Friday, but only if you're over 18. If you're over 14 (but not 18), Du don't have to fast, but Du can't eat meat. But, I've belonged to two separate Catholic congregations, and they were never strict about the fasting. Their thing was not eating meat on Fridays.

I have an aunt that's Baptist. Her first church didn't celebrate Good Friday at all. Her Sekunde church did, but followed it loosely. They didn't fast, but they didn't eat meat either.

Well I'm allowed to eat but I can't eat meat

all i know is Du can't eat meat and i think Du can't drink alcohol i'm not too sure on that alcohol thing i could be wrong but Du are allowed to eat on good friday

Of course Du can eat! True, it is a special day, but Jesus cares about your physical needs. If you're hungry, he WANTS Du to eat.

we can. but for me, its a "fish" day.
