What’s in Wood Cutting Boards?

And how to pick the healthiest ones

With plenty of time at home in the last 12 months, we've all visited the kitchen more frequently – and gladly. This, of course, means that we're basically certifiable chefs. (And how could we not be after streaming all of the known tele-verse? There's now time and much inspiration to mince fresh garlic into culinary fairy dust.) While you've been chopping away, have you ever wondered what goes into those beautiful wooden or bamboo cutting boards? Especially the ones with blocks of wood artfully stuck together? We wondered too, so we looked into it. Read on to learn more!

Wood: the Good

Prepping food on wood or bamboo cutting boards has a number of known benefits. Unlike plastic, wood doesn't contribute microplastics into our food (or the environment!), and bamboo is a quickly regenerated sustainable resource. Wood materials also have antimicrobial properties, in part because they can absorb and trap bacteria deep in the wood fibers! (3) Studies have shown that properly cleaned and dried wood cutting boards harbor very few live bacteria on the cutting board surfaces (1-5).

What About the Other Stuff?

Some wood cutting boards are crafted out of single blocks of wood, but more commonly they contain pieces that are glued together. Cutting board materials fall under the FDA's "food contact substances" and "indirect food additives" regulations since any part of a cutting board could potentially touch our food (6). When FDA-approved food contact substances like glue resins/polymers are completely cured (totally dried), they are considered food safe (7). Even so, some approved substances like melamine-formaldehyde resins can release harmful gases and cause other issues for human and environmental health (8). Formaldehyde is a known carcinogen, and chronic low-level melamine exposure is associated with early kidney disease, among other problematic health outcomes (9). (See our article on melamine dishware to learn more about why it's not great for health). Petroleum-derived wood preservatives like paraffin wax and petroleum hydrocarbon resin are also not great for the environment.

Another thing to keep in mind is that while the FDA requires imported products to comply with the same US safety regulations, unfortunately sometimes these products are non-compliant (10). Look for products that specifically state that they meet FDA food contact regulations, or ask the manufacturer if you're not sure! Imported wood also might require fumigation with methyl bromide prior to shipping to the US, depending on what type it is and where it's coming from (11, 12). While pest management is an important step to prevent the introduction of disease or invasive species from abroad, methyl bromide contributes to ozone layer depletion and can cause system-wide bodily harm to those spraying it (13). (Bamboo timber is generally allowable without any treatment if it meets certain conditions(14).) The bottom line is that some glues, products, and practices are definitely better than others, so it's a good idea to look for wood cutting boards that minimize these health and environmental risks.

5 Recommendations for Choosing a Healthy Wood Cutting Board

We know it can be overwhelming to research the healthiest options out there, so here are 5 recommendations to help your browsing:

  1. Choose wood or bamboo over plastic – even with the possible concerns listed above, wood is still a better choice for decreasing your microplastic and toxin exposure!
  2. Look for cutting boards made from a single piece of wood (to get you started, here are non-toxic cypress, Vermont maple, and teak options). You can also find Forest Stewardship Council (FSC) certified boards that minimize environmental harm by using sustainably harvested woods.
  3. If you choose a cutting board made from multiple glued pieces (which are frankly beautiful and more widely available), make sure the glue used is free from formaldehyde and melamine. Some bamboo cutting boards like this one have a pressure/heat treated process that allow for a glue-free surface.
  4. Pick cutting boards with mild non-toxic coatings like beeswax (or look for an unfinished one that you can finish yourself with our DIY cutting board oil recipe below!)
  5. If you're not sure what types of glue or coatings a manufacturer uses (or if you want to make sure it's FDA-approved), feel free to contact them and ask what types of ingredients and regulations they use and follow. You would definitely not be the first person to ask! For reference, Titebond III and Gorilla Wood Glue are both considered safer for food contact.

DIY Cutting Board Conditioner Oil

To help you maintain a lustrous, resilient and non-toxic cutting surface, here's our simple cutting board conditioner recipe:

  • 3/4 cup MCT oil (or walnut oil)
  • 1/4 cup beeswax
  • Directions: Melt the oil and beeswax together in the microwave or on the stovetop, then brush the mixture onto your cutting board and let it soak in for 3 hours. You can seal your boar as often as once a month, but we find that sealing it just a few times a year works well too!

If you're looking for a refresher on wood cutting board cleaning recommendations, we've got you covered here. Enjoy your culinary endeavors!

Your Summer Guide to Water Safety

How to Promote Fun and Prevent Drowning

Summer has arrived! Cue the backyard BBQs, ice cream sandwiches (or DIY popsicles), and Will Smith jams. During long, hot days, water activities are basically a necessity for creating fun memories and staying cool. Unfortunately, water-related accidents are a leading cause of injury and death for young children (4). So to keep things fun this summer, let's talk about drowning prevention.

Drowning happens in seconds and often quietly (1,3). Permanent disability can result even when drowning isn't fatal (3), since any prolonged oxygen disruption injures our brains. Though it can happen to anyone, drowning is the second most common cause of death for 1-4 year olds (3). Almost 90% of these incidents occur in home pools and hot tubs5,6 (and anything that collects water, even buckets, poses a risk) (3). To keep the children in your life safe and cool, here are 5 water safety tips as recommended by the American Academy of Pediatrics, CDC, National Safety Council, Pool Safely, and Red Cross.

1. Kids' water activities require close supervision at all times

Most drowning incidents occur unsupervised when adults briefly step away or become distracted (4). For this reason, children need vigilant supervision by a designated adult whenever they're around water (4). We can appreciate a relaxing poolside novel or margarita, but the responsible adult/Water Watcher (7) needs to be completely free of alcohol impairment and any distractions (not even Insta). Consider water supervision to be like your greatest Netflix binge – your attention is totally focused, and you don't want to miss a thing. For young children the guiding principle is "touch supervision"– being within arm's reach at all times (3). 5-9 year olds are more likely to drown at public pools (4), so designate a supervising adult even when lifeguards are present (3).

2. Modest safety measures make a massive difference

Physical safety measures are imperative, especially when delightfully curious and unintentionally stealthy toddlers attempt to swim without you! Installing the right type of fence can reduce drowning risk by over 80% – 4-sided pool fences (completely isolating the pool) are far more effective than 3-sided property line fences (3). The safest fences measure at least 4 feet high, prevent climbing, and have self-latching, self-closing gates (3,7). Door alarms and rigid pool covers are also preventive, though their effectiveness is less studied (1). Always check that the pool you use has intact anti-entrapment drain covers (mandated by federal law) to prevent suction-related accidents (7). For portable pools, check out this specific safety guidance.

3. Life jackets are way better than floaties

Sadly those super cute floaty wings aren't designed for safety, according to the CDC, and should not replace life jackets (3) (on the upside, this means less flimsy plastic!). Young children and inexperienced swimmers should wear a U.S. Coast Guard-approved life jacketwhenever near water (1,9). And, regardless of swimming ability, all children need USCG-approved life jackets if playing around lakes or the ocean (2). Life jackets are only effective if they fit well, so check the weight and size limits before using (9). Remember that nothing replaces close supervision! (To help start your life jacket search, we tracked down a more eco-friendly option.)

4. Teach children swimming and water safety

Learning to swim is crucial for water safety. We all benefit from learning how to swim, and swimming lessons can prevent drowning in 1-4 year olds (3). It's never too early (or too late!) to learn – YMCA and community centers often provide affordable lessons for all ages. (We get that communal activities are probably not your jam with the current Covid-19 situation, but, at some point, formal swim lessons could be a fun family activity.) Knowing how to swim does not make us "drown proof" though, so we still need to exercise caution with kids of any swimming ability (1). Teaching children not to climb over pool fences, swim without an adult, or play near pool drains is also crucial for preventing drowning incidents (7).

5. Assess surroundings and swimming ability

Being aware of location-specific water dangers and knowing a swimmer's ability can help discern which activities are safe. Every water activity presents an assortment of fun and risk. Case in point: sprinklers are a simple joy but also an understated toe hazard (been there…). Oceans, rivers, and lakes offer wilder adventure yet can even prove dangerous for expert swimmers – rip currents are an infamous threat in oceans, and lakes and rivers can have undertows (6). Older children and adolescents are more likely to drown in these natural bodies of water (3). Since alcohol can impair your ability to assess surroundings and react appropriately, avoid drinking while swimming or supervising others (7).

Prevention first, but CPR can still save lives

We hope you'll never ever need to use CPR...ever. Prevention with the above measures can massively reduce drowning risk for everyone, but CPR is invaluable during a drowning incident and can improve the likelihood of the drowning victim's survival (3). The American Heart Association provides in-person Family and Friends CPR courses, as well as socially distanced, at-home instruction with Family and Friends CPR DVD or Adult/Child CPR training kits (includes a training manikin and DVD – fun for the whole family!).

With safe water play, we know your summer days will be full of adventure and excitement. Have fun!

Plastic-Free (and Melamine-Free!) Outdoor Tableware

They won't break, look great, and are sure to be perfect for you outdoor gatherings

Updated for Summer 2022!

Getting ready for some outdoor parties and dining this summer? We sure are! If you're looking to spruce up your outdoor dining scene, you'll quickly see that most options are made of melamine. Even though melamine dishware doesn't look like plastic, melamine can leach into food after dishes are repeatedly microwaved or used to hold both hot and acidic foods (read this to learn why you might want to skip the melamine). So if melamine is out, and easy to break options like ceramic just don't work for you (children being children, slippery surfaces, clumsy grownups!), check out these stainless steel, enamelware, wood, and tempered glass options. Although we always recommend reusable, we included one disposable option too (without PFAS chemicals). These are our top picks for plastic-free outdoor dishware, serving bowls and platters, tumblers, and more. They are all light weight, hard to break, and will make your outdoor entertaining photos look on point. So pick up some of these plastic-free and melamine-free outdoor dishes and enjoy dining al fresco!

As much as we'd like to be the type of person who wakes up early, grabs some buckets and a sponge at home, and spends a few hours giving their car a DIY wash, we often find ourselves pulling into a car wash business instead. It's easy to feel guilty about taking the "convenient" route but in this case you don't have to! It's actually better for the environment to get a professional car wash rather than DIY! We break down the benefits of an automatic car wash below.

Whether you have a brand new car or your car has been with you for a decade and a few hundred thousand miles, chances are you want to take care of it. In addition to regular oil changes and tune ups, you need to give it a good cleaning. Washing your car isn't just for looks. Over time your car accumulates dirt, oil, salt, and other grime. As well as being an eyesore, this debris can damage the performance of your car. Since we want to drive our car for as long as possible, washing it should be part of your normal car maintenance routine! But before you run to grab your hose and bucket- you might want to consider heading to your local car wash.

It's common to think that going to the car wash is worse for the environment and too water intensive, when actually, the opposite is true. Car wash businesses use high powered nozzles to use as little water as efficiently as possible, and many businesses also have a system in place to catch and reuse old water (1). When you wash your car yourself, you probably just use a bucket filled with water and a hose. While your water usage may not seem that bad while you're washing, it adds up fast. Individuals can use between 80 to 140 gallons of water to wash their car, but a car wash business only uses about 30 to 45 gallons of water (2)! Many car washes also recycle the water used, so the water can be used many times. Some states even require car washes to use recycled water; in California, car washes must use at least 60% recycled water (4). During one particularly tough drought season, a city in California went so far as to ban using potable water for at-home car washes and required car owners to go to a car wash to clean their car (5). If you are concerned about wasting water, ask your local car wash if they recycle water and try to go to one that does!

Another reason to consider using a professional car wash business is wastewater. When we wash our cars at home, we're usually in a concrete driveway or on the side of the road and let the water run down to the sidewalk drains. But that water contains dirt, oil, heavy metals, and other harmful chemicals that accumulate during normal driving, and those sidewalk drains don't go to a water treatment plant. Instead, that runoff is usually diverted directly into our watershed, which might to a lake, stream, or ocean and negatively impact aquatic wildlife and water quality (3). Professional car wash businesses are required by the Environmental Protection Agency to capture all wastewater and divert it into a sewage system. That means the water is safely processed through a water treatment facility and can be used for future car washes!

If you really want to wash your car at home, there are more eco-friendly options.

1. Look for cleaners that are biodegradable and phosphate-free, to minimize the potential for water contamination (3).

2. Make sure to dispose of any dirty water leftover in the buckets by dumping it down your sink, toilet, or bathtub instead of pouring it down your driveway.

3. Washing your car on an overcast, mild day can help save water, since it won't evaporate as quickly.

4. Use reusable cloths to wash and dry your car.

Now that you've invested in some glass and stainless steel food storage containers, maybe you're wondering if you should Marie Kondo all the plastic ones you used to use? Instead adding them to the landfill, what if we told you that all those plastic containers can help you achieve a new level of organization zen? While we don't recommend storing food in them anymore (for those of you who haven't heard: these plastic food storage containers often have BPA or phthalates in them, which can leach into your food over time and cause all sorts of health problems), we also don't think you have to throw them away.

So, what can you do? We have 6 great suggestions for you to repurpose those containers throughout your home.
