Is Your Cutting Board Adding Some Microplastics to Your Meals?

The Hidden Problem in Your Kitchen

Plastic cutting boards are popular for their lightweight design, affordability, and dishwasher-safe convenience. But recent studies reveal a troubling downside: every knife stroke can release hundreds of microplastic particles into your food. (Time)  One study found that chopping carrots on a plastic board left behind over 1,000 microplastic fragments per use, adding up to about 50 grams of plastic per year—the equivalent of eating 10 credit cards.

Microplastics are not just an environmental issue. They’ve been detected in human blood, lungs, liver, kidneys, heart and even in breast milk, raising concerns about long-term health effects. While research is still emerging, evidence suggests microplastics may “be linked to cancer, heart attacks (Stanford) and contribute to inflammation, oxidative stress, and even neurological risks. (Medical Express) 

Why Plastic Cutting Boards Are Riskier Over Time

Ø  Knife marks: Once scarred, plastic boards trap bacteria and release more particles.

Ø  Dishwasher wear: Heat and detergents accelerate breakdown.

Ø  Invisible contamination: You can’t see microplastics, so you may not realize you’re ingesting them.


What to Use Instead

If you are ready to ditch plastic cutting boards, the Environmental Working Group (EWG) suggests wood, bamboo, glass and other durable alternatives:

🌳 Wood Cutting Boards

    • Classic choice, naturally antimicrobial.
    • Best for bread, fruit, and vegetables.
    • Requires handwashing and occasional oiling.

🎋 Bamboo Cutting Boards

    • Lightweight, sustainable, and harder than many woods.
    • Affordable and eco-friendly.
    • Can dull knives faster than softer woods.

🧩 Composite Boards (e.g., Epicurean)

    • Made from compressed wood fibers and resin.
    • Dishwasher-safe, durable, and knife-friendly.
    • Great balance between convenience and safety.

🪞 Silicone Cutting Mats

    • Flexible, non-toxic, and easy to clean.
    • Ideal for small kitchens or prepping multiple foods.
    • Mats can go in the dishwasher without degrading.

🛡️ Rubber Cutting Boards

    • Heavy-duty, used in professional kitchens.
    • Gentle on knives, long-lasting.
    • More expensive but worth the investment.

Final Thoughts

Switching from plastic cutting boards isn’t just about protecting your health, it’s also about reducing microplastic pollution in waterways when boards are washed. By choosing wood, bamboo, silicone, or composite boards, you’ll not only cut down on hidden plastic in your meals but also make your kitchen more sustainable.

Bottom line: If you’re still chopping on plastic cutting boards, it may be time to upgrade. Your food—and your body—will thank you.

Watermelon: A Powerhouse of Health Benefits

Image
Who doesn't enjoy some fresh watermelon?  So juice and naturally sweet.  At a buffet over the weekend, I saw person after person loading their plates with freshly sliced watermelon.  Many people enjoy watermelon and don't realize how healthy it is.   Cleveland Clinic   says, “watermelon should be part of your diet”.  Why?  Watermelon is “packed with vitamins and minerals and can be enjoyed all year ‘round”.   We hear a lot about superfoods like blueberries, but we don’t hear much about other fruits like watermelon.  Watermelon packs a big nutritious punch. One reason why watermelon is so good for your health is that it is loaded with many vitamins and minerals as well as fiber.  Vitamins : watermelon is a good source of vitamins A, C and many B vitamins.  One cup of watermelon balls provides 12.5 mg of vitamin C, almost 25% of daily needs.  One cup also provides 876 IU of vitamin A, almost 20% of daily needs.  Mineral...

Lots of people are talking about what RFK, Jr. may do to the food industry as he focuses on making foods healthier with less additives and chemicals.   Many articles have been written about it.   What foods might be affected by health policies favored by RFK, Jr.? Foods with additives:   Ever take the time to read the ingredient label on foods?   So many have ingredients that are hard to pronounce and most people have no idea what the chemical or additive is.   Food manufacturers add chemicals “to enhance flavor, color, or shelf life” but in doing so such chemicals may adversely affect our health.   Food Dyes :   EWG notes that three food colors comprise 90% of the food dyes in food, including Red Dye No. 40, Yellow Dye No. 5, and Yellow Dye No. 6.   o    Red Dye No. 40 – so many foods have been colored with red dye including candies, snacks, and many beverages like fruit punches and fruit drinks.   In fact, EWG says “more ...
