A few months ago, I came across something that truly blew my mind..A study by the University of Newcastle found that people may consume up to 5 grams of plastic per week, which is roughly the weight of a credit card. Other studies came out later to clarify that this estimate was on the very upper end of the range estimated, but still— it kinda was an eye opener to me.

I mean, we tend to avoid plastic when possible; we have reusable glass as much as possible, rarely use single-use plastics, and opt for more sustainable and healthy options when available. But I also am not a stickler about it.

It got me curious though, what are the most common sources of plastics and microplastics that we come into contact with every day?

The Health Risks of Plastics

So why even worry about plastic exposure? Plastics are loaded with synthetic chemicals, many of which can have detrimental effects on the human body. The most well-known ones include BPA (Bisphenol A) and phthalates, which are commonly found in plastic food containers, water bottles, and even toys. These chemicals are known as endocrine disruptors, meaning they interfere with hormone function. Over time, exposure to these compounds can lead to serious health issues, including:

• Hormonal imbalances

• Increased risk of cancers, especially breast and prostate cancers

• Reproductive problems

• Developmental issues in children

But what many people don’t realize is that these chemicals don’t just sit in the plastic—they can leach out, especially when plastic is exposed to heat. This means that microwaving food in plastic containers, leaving a plastic water bottle in a hot car, or using hot liquids in plastic cups can significantly increase your exposure to harmful toxins.

Over time, this adds up, posing cumulative health risks.

Please read that last sentence again— “over time” and “cumulative” being the keywords. Using plastic ones isn’t going to cause problems, despite what social media and the news may tell you. Fear sells and I strongly believe that we do not need ot live in fear, but instead can be aware in order to make mindful choices for our health and environment.

Speaking of the environment…

Plastics have also wreaked havoc on nature. Since most plastic is made from petroleum-based materials, it takes hundreds of years to break down. As a result, the plastic items you use today will outlive you, your children, and likely your grandchildren. This leads to long-lasting pollution. Two main effects include:

• Pollution of Oceans and Waterways
  Every year, millions of tons of plastic enter the oceans, harming marine life and disrupting ecosystems. Sea animals, from turtles to whales, often mistake plastic debris for food, leading to ingestion and eventual death. Plastic doesn’t just disappear either; it breaks down into microplastics, tiny particles that have been found in fish, salt, and even our drinking water.

• Landfill Overload
  Plastic waste takes up valuable space in landfills, and since it doesn’t biodegrade, it stays there indefinitely. The chemicals from these plastics can seep into the soil and groundwater, contaminating entire ecosystems.

The Dangers of Heating Plastic

One of the most dangerous aspects of plastic is its tendency to release harmful chemicals when exposed to heat. Whether you’re heating up leftovers in a plastic container or drinking from a plastic bottle that’s been sitting in the sun, you’re increasing your risk of ingesting these chemicals. The heat causes plastics to break down at a molecular level, releasing toxins such as BPA and phthalates into your food and beverages.

Scientific studies have shown that these chemicals are linked to a range of health issues, from disrupted hormone function to developmental disorders in children. Worse yet, once these chemicals enter your system, they can be difficult for your body to expel.

Most Prevalent Sources of Plastics and Microplastics

When I first started becoming more aware of plastics, I was honestly really shocked. Somehow, it seemed as though plastics had infiltrated every area of my life! Plastics, which are often hidden in everyday items, can release harmful chemicals or break down into microscopic particles, which we inadvertently ingest, inhale, or absorb through our skin. Here are 10-15 of the most common sources you may encounter daily and the best replacements!

• Food Packaging
  Most food packaging is made from plastic, from the bags for produce and deli meats, to plastic wrappers on snacks. Even packaging labeled “biodegradable” often contain some amount of plastic that breaks down into microplastics.

  • If possible, bring your own reusable mesh produce bag when grocery shopping, or opt for paper bags.

• Plastic Water Bottles
  Single-use plastic water bottles are one of the largest sources of both waste and exposure to leaching chemicals like BPA, especially when exposed to heat. Repeatedly using these bottles can increase the breakdown of plastic into your water.

  • Purchasing a stainless steel, refillable water bottle is a great way to minimize plastics! I also purchased reusable stainless steel straws to swap out the plastic one that comes with the bottle (seriously, plastic is everywhere)

• Takeout Containers
  Many takeout containers, especially the clear or foam ones, are made from plastic. And most often, we are getting hot food which then increases your exposure to these chemicals.

  • Look for places that use paper or fully biodegradable options.

• Personal Care Products
  Microplastics are often found in exfoliating face washes, body scrubs, and toothpaste in the form of tiny beads or synthetic polymers. These microplastics go down the drain but don't break down, entering waterways.

  • Opt for skincare and beauty products with more natural ingredients. I share about several brands regularly on this blog, but here are a few favorites!

    • Primally Pure

    • Butter Me Up Organics

• Tea Bags
  Shockingly, many modern tea bags are made from synthetic plastic fibers. When placed in hot water, these plastic fibers can release microplastics into your tea. Opt for loose-leaf tea or tea bags made from natural materials.

  • Stainless steel tea infuser- this is a great option for loose-leaf teas!

• Clothing
  Synthetic fabrics like polyester, nylon, and acrylic, commonly used in fast fashion, shed microplastics when washed. These fibers are too small to be filtered out by wastewater treatment plants and end up in our oceans and drinking water.

  • I am honestly not the best with this— but I have slowly been trying to prioritize more natural fibers in my clothing. Not only are they better for your health but I feel like they hold up so much better.

• Food Storage Containers
  Even if they are labeled as “microwave safe,” plastic food containers can still leach harmful chemicals into your food when heated. Over time, repeated use can cause these containers to degrade, further increasing exposure.

  • Swap your old tupperware products for reusable glass ones! I also love using mason jars for food storage.

• Disposable Utensils and Straws
  Single-use plastic utensils, straws, and plates are big sources of plastic waste. These items break down into microplastics and contribute heavily to pollution, both in landfills and waterways.

  • purchase a reusable set (this one is made of wheat straw and comes in the most fun colors!) to keep in your purse or diaper bag for eating on the go!

• Wet Wipes
  Most wet wipes, including baby wipes, facial wipes, and disinfecting wipes, contain plastic fibers that do not break down easily. They contribute to plastic pollution and clog sewage systems.

  • try to opt for plastic-free wipes!

• Plastic-Lined Coffee Cups
  Disposable coffee cups often have a thin plastic lining to make them waterproof. When you pour hot liquids into these cups, microplastics can leach into your drink.

  • Bring along your own cup or thermos! Most places will now put your drink into your own cup as long as it’s clean.

• Household Cleaning Products
  Many cleaning sponges, scrubbers, and brushes are made from plastic. Over time, they degrade and shed microplastics into your kitchen and bathroom sinks, where they enter the water system.

• Toothbrushes
  Conventional toothbrushes are made from plastic, and billions are discarded annually, adding to landfills. Though they don’t shed microplastics while brushing, their disposal contributes to environmental waste.

  • I recently bought these plant-based bristle bamboo toothbrushes for my kids and they’re great!

To wrap it up

I always want to preface information with a warning— none of this is something to be scared of, or live in fear of. But I do think it is important to be aware of so that we can make mindful, educated decisions for our health as well as for those around us!

All these swaps also do not have to happen at the same time. I replaced our old, plastic tupperware 6 or 7 years ago, but I still have a closet with tons of polyester and acrylic (although I am working on replacing it as I buy new pieces). It’s a gradual process, and I tend to replace something when it needs to be replaced— not immediately, all at once.

Let me know if any of this was surprising, or how you mitigate plastic usage in your own life!
