1. Anything could be grown

2. It could give them immortality but it could also be like eden and get them banished.

The shear power of divine that comes from the fruit/vegetable/meat is to much for normal mortal to handle maybe if consume in small quantities like 1 bite then maybe idk

It varies in how much they can eat.

What kind of food could be grown in a divine environment and what would be the effects if someone ate food from such a place?

It varies ,if it was Greek mythology it would ambrosia the food or drink of the Olympian gods, which was thought to bring long life and immortality to anyone who consumed it. Then that would be it . I could be food that elevates mortals to God hood or gives them cosmic knowledge but it varies . Usually it's too much for mortals to handle . But that's my answer .

Let me know your thoughts about it and other ideas for this kind of environment.

I think divine environment is pretty cool since you pretty much control the places where gods and other divine entities reside which could be heaven or Asgard or an entire dimension of eldritch divine universe destroying entities . The possibilities are countless in number . I think it's up there with my other favorite called eldritch location manipulation . If you've seen eldritch locations on tv tropes you'll know why I love that power .

Love your explanation @Nyarlathotep99 👌

I was also thinking that those who eat food from a divine place would naturally also have Divine Empowerment. Not to mention also if someone has Supernatural Cooking, this could lead to other effects.

Indeed it would ,I'm glad you agree .

you could create or breed a little bit of everything from invincible beasts with special abilities, elixirs or herbs that give op powers etc... this can change, in mythology there are various changes that can happen in divine domains some have no problem others they have a price
