Hey TJ, Welcome to the forum. Why don't you go over to the introduction page and introduce yourself.
As Jim said. all finishes sold in the U.S. are food safe once they are cured. but most wont be water proof. For bowls, mineral oil will work as will the salad bowl finishes available at any woodworking store or online. You don't want to put the bowls in the dishwasher or submerge in water. But with mineral oil or the salad bowl finishes, it is easy to touch up the bowls.
For drinking mugs, The only thing that will be waterproof is epoxy. I have never done this before, but I have seen wooden mugs with it. good luck!
