Wood-working? What type of sealer/varnish could I use for wooden vessels/utensils that would be food-safe?

There are a number of them available, including shellac... but a popular choice is a food grade oil like walnut oil.

It's different for every person. It's not really logical. I used to eat bananas and parmesan cheese (sprinkled on lettuce) and those foods are often on a lot of people's unsafe list. Then again, I could never eat yogurt or almonds (when I found out they were seven calories each and two calories from fat, I felt more betrayed than Jon Snow) but a lot of anorexics would totally eat these. Generally an anorexic will find a few foods that they feel they can eat and portion safely, and have weird obsessions with them. I would down packets of aspartame and binge on frozen corn (your body can't process the nutrients in that form). A lot of anorexics will eat rice cakes, though I never could because carbs. Diet Coke is an entire food group. Seriously, even though it hurts like a ***** to swallow, you just constantly down it. Obviously green tea, lettuce, celery is a big one.

I'm not sure that many of them are *truly* food safe (especially if the contact with a *wet* food or drink involves heat, acidic foods/drinks, long contact, etc.).

In general, polyurethanes will "seal" bare wood (just like an acrylic paint would) but they're still not usually used directly for food or contact with mucous membranes.

Some of the waxes for wood may be safer than the "sealers" when in direct contact with food and the body --especially in the ways described above-- but I don't know about that. You might want to ask in some of the woodworkers' forums where wood bowls, etc. are turned on lathes, etc.

It's certainly not common to use wood directly for drinking vessels or wet foods.

P.S. I just checked the link given by the answerer before me and there are a *few* oils listed which say specifically that they're safe for food contact, and even one that says safe even for acidic foods, etc.

There may be other negative things about those oils, but at least they seem to be "safe for food" (e.g., perhaps they transfer their flavors?, or need to be continually reapplied for real waterproofness and smoothness?, or aren't that good for standing liquids?, won't give a glossy finish?, etc).

I'd still probably ask specfically about using those kinds of finishes *for drinks* in a relevant forum.
