Every repeater item is given an ID that you can access inside a foreach with $item->id (or $x->id, in the case of your foreach). You can see on the screenshot that you posted, that the ID of your single repeater item is 1110. This would be just to see if your foreach is correct, but as I pointed out before, the most important is to understand why the body isn't even appearing in the array. You are sure you added the body to the repeater field, and not to the home template itself?
