Do not destroy the work of God because of food

You can make explicit the full meaning of this sentence. AT: "Do not undo what God has done for a fellow believer just because you want to eat a certain kind of food" (See: rc://en/ta/man/translate/figs-explicit)

but it is evil for that person who eats and causes him to stumble

Here anything that "causes him to stumble" means it causes a weaker brother to do something that is against his conscience. AT: "but it would be a sin for someone to eat food, which another brother thinks is wrong to eat, if by eating this causes the weaker brother to do something that is against his conscience" (See: rc://en/ta/man/translate/figs-explicit)
