I would have liked to leave them natural, but she didn’t like the color. Since this is a food surface, you have limited options for staining and sealing. You can’t use a vegetable oil because it will become rancid. Though staining is not recommended, you could try using a wood bleach such as oxalic acid to lighten the oak before sealing.
The problem is she wants to make them from oak, and the wood has a purplish cast.
Also, oak’s open grain will be more difficult to keep clean compared to, for example, the tighter grain of maple. I would not use a stain because common wood stain is a toxic substance, and not approved for food surfaces. I would get a scrap of the same oak and experiment before committing to do this on an expensive butcher block top.

What’S The Best Countertop Material? by granite-countertop-info.com
Granite is the choice for many applications due to its hardness, durability, and scratch resistance. Knowing the characteristics of natural stones will help you decide which ones will suit your needs on counters. Here are some answers to your questions on granite and marble countertops.
Granite is igneous meaning it formed naturally as molten rock millions of years ago. All stones that perform, work, or behave like granite are called granite. Granite, however, is heat resistant and nearly impossible to scratch. Granite repairs are chemically durable, impact and shock resistant and polishable to a high gloss.
Don’t just consider how the stone looks, or you could be very disappointed with your stone tops in no time. Granite is igneous meaning it formed naturally as molten rock millions of years ago. And though you’ll find a geological definition for granite, the commercial definition is quite broad. The fact is, stones such as gabbro, diorite, and anorthosite are all called granite in the countertop world.
Other synthetic countertop materials scratch easily and can melt from placing hot items on them. It will not stain under normal use and it’s unaffected by citric acid, wine, tea, coffee and most anything else. The quality of granite counter tops goes well beyond the material itself. Natural stone including limestone , marble, and granite, offers distinct advantages and disadvantages as countertops. Natural quartz surface has been getting a lot of press lately as the best countertop material on the market.

The unique beauty of each stone is why many homeowners decide on natural stone. A slab from the same stone family or even the same quarry may appear similar, but have a different threshold for absorbing liquids. With factory honed surfaces, or softer and more porous stones, liquids can enter the surface more freely and therefore require a sealer. Applying an impregnating sealer is a common precautionary practice against staining.
It’s important to note, sealants are more accurately described as a repellent than a sealer and do not make the stone stain proof, but it does help make the surface more stain resistant. When the surface doesn’t repel water or oil, the surface needs to be protected and it’s time to apply or reapply with the brand of sealer originally used. Leave water on the slab for 10 minutes and then wipe dry; if the stone doesn’t appear darker in that area, then granite won’t absorb water-based material that may stain it and it won’t absorb a water-based sealer, either. The area darkened by the mineral oil for testing purposes will eventually completely evaporate, leaving the stone its natural color. In short, if there isn’t a change in color after testing with these two liquids, you don’t need a sealer on your granite countertop. Due to the inherent qualities natural to marble, an impregnating sealer will not protect marble against water rings, oil spots and stains. If a sealer is applied in a food preparation area, be sure that it is non-toxic and safe for use.
These unique characteristics also mean that no two stone slabs have the same absorbency qualities. In today’s stone industry, many factories are cutting the blocks of granite into slabs, polishing them and using a resin treatment to fill micro-fissures, pitting and other minor characteristics considered by some consumers as imperfections. Polishing, in combination with the resin coating restricts the ability of liquids to enter. An after-market sealer applied to this type of stone can leave a hazy film on the surface.
Only a low percentage of natural stone surfaces need to be sealed because granite is the main stone variety in use, and not all granites are fully absorbent. Some high traffic areas or places frequently exposed to moisture and sun may need to be sealed more often than others. You can use a similar test to determine if your stone can be stained by oil based products. If that area appears darker after you remove it, you should use a solvent-based sealer to protect against oil based stains. If it doesn’t darken the stone, oil or other common household petroleum based agents shouldn’t stain it either. Marble is the one natural stone that is the exception to the rule when it comes to sealants.
In fact, blemishes on the surface may appear as stains or unfinished areas, but in reality the surface is etched, caused by corrosion between the calcium in the stone and common acidic fluids that come in contact with the stone.

When considering sealing, remember that sealing the stone does not make the stone stain proof, it makes it more resistant to staining.
Food Safety and Wood Countertop Finishes by woodweb.com
Filling the grain – perhaps with a contrasting color – would make a smoother, more easily cleanable surface.
If you go the tung oil route, you can sand in the first few coats, which will fill the grain also.
So what about this filling the gain with a contrasting color? The staff at your finishing supply provider may help you pick one and can probably even tint it for you. Thin your filler to the consistency of ketchup and spread it evenly over the oak. Sand the whole thing to remove any unwanted color from the high areas, leaving the color in the low spots. To the original questioner: the best coating for your need depends on the expected use of the counter. Is there one site that indicates the coatings that are approved? Particles of finish just don’t detach from the film to migrate to your food. What finishes would you be wary of allowing your sandwich to touch? If someone has a countertop and subsequently develops an illness (even lung cancer and even if they smoke), it is indeed possible that they will look for causes of this or another illness. What is safe for one woodworker under certain conditions may not be safe for others in different circumstances.
You don’t want your customer scrubbing it with a bristle brush.
I get the sense that you want to stay with the natural colors of the oak. Clean out the open grain with a brass-bristle brush and compressed air. Have heard of an epoxy formula for using on countertops, but is appears too glossy for me. For use on a cutting board, you’d want a non-film finish so you wouldn’t be eating chips of finish flaked off (not that they would be likely to hurt you any more than any other minute scrap of plastic you might ingest).
Some other finishes, such as poorly cured urethane finishes or shellac, can be soft and unsafe to eat. A knife can cut soft finishes (hot or cold) and leave a scratch that accumulates bacteria. I agree that improperly cured urethane, or any other improperly cured finish isn’t safe, but who would flop down a slice of bread for a sandwich on a sticky counter? If it is near the sink, for instance, you may need a different finish than if it is just for a prep area. What it boils down to – there is no specific requirement for any finish to apply to be deemed food safe, as the ingredients that go into the finish (and remain – solvents don’t count) are already classed as food safe (such as the oils that go into varnishes) and any dangerous components (such as lead) are already banned. He came into the forum and said that although finishes are inherently food safe, no manufacturer is going to label their product that way because there is no requirement to and there is no regulatory body to issue an approval.
As to the “casual contact” statement, my source is common sense and my knowledge of how paint dries. Few, if any, coatings manufacturers will warrant their product if hot pots are going to be set on them regularly.
But since we do not expect our finishes to end up in food, it is likely that we do not have a food safety issue here. If the coating used on the counter has some risk of being unsafe and causing a disease in animals, etc., they will add the provider of the countertop to their list of people that they are suing. We are not finding a regulation that connects what we do with food safety. Should we be worried about potential liability on this one? If any water gets through and there is any iron, the countertop with develop iron tannate stain, a blue-black color.
