Microplastics are all around us, from the water we drink to the food we eat. These tiny plastic particles pose a growing problem for both our health and the environment. The issue of microplastics is closely linked to the broader problem of plastics and the various types of plastics used in countless everyday products. These types vary depending on desired properties such as strength, weight, and color, and contribute to the spread of microplastics. In this blog, you will learn what microplastics are, where they come from, and how you can avoid them – especially through food and when shopping at the supermarket.
What are microplastics?
Microplastics are very small plastic particles, often smaller than 5 millimeters. They are classified into two categories:
-
Primary microplastics: These are particles that are intentionally made small, such as microbeads in cosmetics or plastic fibers in synthetic clothing.
-
Secondary microplastics: These are formed when larger pieces of plastic (such as bottles or bags) break down due to wear, sunlight, or weathering. Different types of plastics can break down into microplastics, depending on their properties and applications, such as strength, weight, and color.
Although small, microplastics have a significant impact on ecosystems and potentially on our health.
How do microplastics form?
Microplastics form in several ways. One of the main sources is the breakdown of larger plastic objects, such as plastic bags, bottles, and other products. This process is accelerated by exposure to sunlight, wind, and water. When these larger pieces of plastic are exposed to the elements, they slowly break down into smaller and smaller particles until they eventually become microplastics.
In addition, microplastics can also be released through the use of plastic products in our daily lives. Examples include cosmetics and detergents that contain microplastics as abrasives or fillers. These tiny particles are released into the environment during use and washing of clothing. Microplastics can also form during the production of new plastic products, such as the grinding of plastic pellets. It is clear, therefore, that microplastics enter our environment in various ways and pose a persistent problem.
How do microplastics enter our bodies?
According to research, the average person consumes approximately 5 grams of microplastics every week. That's a shocking amount when you consider how small these plastic particles can be. They enter our bodies in various ways:
- Food and drinks: Think of fish, seafood, water from plastic bottles, and even packaged food.
- Air: Microplastics are also present in the air we breathe.
- Cosmetics: Some personal care products contain microplastic as an abrasive or filler.
- Clothing: Synthetic fabrics like polyester release microfibers during washing.
Plastic waste and microplastics
Plastic waste is a major environmental problem. When plastic waste is not disposed of properly, it can end up in the environment and break down into microplastics. These small particles can then be ingested by microorganisms and other animals, entering the food chain. This can have harmful effects on the health of humans and animals, as the toxic substances in microplastics can accumulate in the tissues of organisms.
It is therefore crucial to dispose of and recycle plastic waste properly. By correctly recycling plastic products, we can reduce the amount of plastic waste in the environment and limit the formation of microplastics. In addition, by making conscious choices in our daily lives, such as avoiding plastic packaging and opting for sustainable products like laundry strips and toilet cleaner strips, we can contribute to a cleaner environment and a healthier future.
How to avoid microplastics through food?
Food is a significant source of microplastic exposure. Here are tips to reduce your intake through healthy food:
-
Drink from glass or stainless steel:
Plastic water bottles release microplastics, especially with long-term storage. Choose reusable glass or metal bottles. -
Filter your tap water:
Use a good water filter, such as a carbon filter or reverse osmosis, to remove microplastics from your drinking water. -
Choose unpackaged, fresh produce:
Buy loose fruits and vegetables, without plastic packaging. Use reusable bags instead of disposable ones. -
Be critical of seafood:
Fish and shellfish absorb microplastics from polluted water. Choose fish from reliable sources or avoid shellfish like mussels and oysters. -
Watch your salt:
Sea salt often contains microplastics due to ocean pollution. Choose Himalayan salt or rock salt as an alternative. -
Use natural tea bags:
Nylon tea bags release plastic particles when heated. Choose loose leaf tea or paper bags. -
Store food in glass or stainless steel:
Avoid plastic containers, especially in the microwave or dishwasher, as heat can accelerate the release of microplastics. -
Eat less processed food:
Processed food is often packaged and processed in plastic, which increases the likelihood of microplastic contamination.
How can you avoid microplastics in the supermarket?
When shopping, you can make conscious choices to reduce plastic use:
-
Choose fresh and unpackaged food:
You can often buy loose vegetables, fruits, and bread. Avoid pre-cut products in plastic. -
Use reusable packaging:
Bring your own cotton bags and glass jars to the supermarket. -
Choose glass packaging:
Buy water, sauces, and drinks in glass bottles instead of plastic. -
Support sustainable brands:
Choose companies that offer environmentally friendly packaging and plastic-free alternatives. -
Sustainable products for daily use:
Consider eco-friendly alternatives such as laundry strips, toilet cleaner strips, and other sustainable options to reduce your environmental impact.
Why is it important to avoid microplastics?
Microplastics are not only a problem for our health but also for the planet. By being more conscious of your diet and packaging, and by choosing sustainable alternatives such as eco-friendly products, you contribute to a cleaner world. Consuming 5 grams of microplastics every week might seem small, but over a year, that's more than 250 grams – and that's just from food!
Consume consciously
Microplastics are everywhere, from our food to the air we breathe. By making conscious choices in the supermarket and when choosing products, you can reduce your exposure to microplastics. Choose glass instead of plastic, buy loose products, and support sustainable alternatives such as laundry strips, toilet cleaner strips, and more. Small changes in your daily life can have a big impact, both for your health and for the planet.
