Your Cutting Board Matters More Than You Think

You probably think of your cutting board as one of the least important things in your kitchen.

It holds your vegetables. You chop your chicken. You rinse it. You put it back in the cabinet.

But there’s a good reason to take a second look at what you’re cutting your food on every day. The material can affect your knives, food hygiene, durability—and potentially what ends up in your food.

The Problem With Plastic

Plastic cutting boards became popular for good reasons: they’re inexpensive, lightweight and dishwasher-friendly.

But there’s a downside that deserves attention.

Research has found that plastic cutting boards can release microplastic particles as knives repeatedly score the surface. And the older and more heavily scarred the board becomes, the greater the potential shedding.

We still don't know exactly what long-term exposure to these particles means for human health. But if your plastic board looks like it has been through a decade of chopping, that's probably a good sign it's time for retirement.

Wood May Be the Better Choice

Here's the surprising part: wood isn't necessarily less hygienic than plastic.

Research cited in the source material found that bacteria such as E. coli, Salmonella and Listeria can die off rapidly on wooden surfaces, while bacteria can persist longer on heavily scored plastic. Wood's porous structure may actually pull moisture and bacteria below the surface, where they become less able to survive.

But not all wood is created equal.

For everyday cooking, maple and walnut are two of the best choices.

Maple is hard, durable and relatively affordable. It's an excellent all-purpose board.

Walnut is somewhat softer, making it particularly gentle on your knife edges, and its darker color hides stains and wear better.

Cherry is even softer and beautiful, but it will show knife marks sooner.

Bamboo is another excellent budget option. Technically a grass rather than a wood, it is durable, affordable and doesn't create the same microplastic concern as plastic. The downside? It's relatively hard on knife edges and can crack if allowed to dry out.

What About Glass or Stone?

I'd skip them for everyday chopping.

Glass, marble and stone are easy to clean, but they're extremely hard on knives. Over time, that hard surface can dull your blades much faster than wood.

My Simple Recommendation

If you're buying one board, choose a maple or walnut end-grain cutting board.

End-grain boards are constructed so the wood fibers run vertically. Instead of the knife slicing directly across the fibers, the fibers separate slightly and recover, which is easier on your knives and helps the board withstand years of use.

And if you're still using a plastic board covered with deep knife grooves, don't overthink it.

Replace it.

The Longevity Lesson

We spend a lot of time thinking about what we put into our bodies.

Maybe we should occasionally think about what we're preparing it on, too.

A quality cutting board isn't a miracle health intervention. But it's an inexpensive, everyday upgrade that can improve your cooking experience, protect your knives and help you move away from a heavily worn plastic surface.

Sometimes better health starts with something as simple as changing what's under your vegetables.
