What You'll Learn
Avoid plastic food storage containers
While it is impossible to completely avoid exposure to plastic, there are several ways to reduce it. One way is to avoid using plastic food storage containers.
Firstly, it is important to note that not all plastic containers are created equal. If you must use plastic food storage containers, opt for food-grade containers that are specifically designed for food storage and are free from harmful chemicals. Avoid single-use containers, such as ice cream or milk cartons, for freezer storage. Only use containers that are labelled as freezer-safe, moisture-vapor resistant, leak-proof, and easy to seal.
Secondly, avoid exposing plastic containers to heat. Do not use plastic containers to store hot food or heat food in them, as heat can increase leaching and accelerate plastic degradation, causing microplastic shedding. This includes microwaving food in plastic containers, even those labelled as "microwave-safe". Instead, consider using glass, ceramic, or stainless steel containers for storing and heating food.
Thirdly, be mindful of the types of food stored in plastic containers. Some foods, such as acidic foods like tomato sauce or anything pickled or citrusy, can chemically react with plastics over time and absorb plasticizers. It is recommended to allow food to cool before storing it in plastic containers to minimize the risk of microplastic exposure.
Finally, consider switching to alternative materials for food storage. Glass, ceramic, and stainless steel containers are safer options that do not pose the same health risks as plastic containers. While plastic containers may be convenient and affordable, making the switch to alternative materials can help reduce your exposure to microplastics and potentially harmful chemicals.

Don't heat food in plastic
Heating food in plastic containers can be dangerous to your health. Research has shown that plastics contain chemicals such as bisphenol A (BPA) and phthalates, which can leach into food when heated. BPA has been linked to serious illnesses, including cancer, diabetes, heart disease, and obesity. Phthalates are endocrine disruptors, which can interfere with the natural balance of hormones in the body, making them particularly harmful to individuals with hormonal disorders or those undergoing hormone replacement therapy.
While some plastics are designed for heating food and are less likely to melt or release harmful chemicals, the plastic lining can still be damaged, allowing toxins to leach into the food. To reduce exposure to these chemicals, it is recommended to avoid heating food in plastic containers altogether. Instead, opt for using plates, glass containers, or ceramic bowls, especially when using a microwave or oven.
Additionally, it is advisable to avoid plastic bottles and cups, as well as plastic cutting boards, as these can also be significant sources of microplastic exposure. Wood, stainless steel, and silicone alternatives are recommended. Carrying your own stainless steel water bottle and straw can help reduce your reliance on single-use plastic items.
While it is challenging to completely eliminate plastic from our lives, adopting strategic habits can significantly reduce our exposure to harmful chemicals. This includes avoiding heating food in plastic, choosing alternative materials for kitchen utensils and food storage, and being mindful of the potential health risks associated with plastic usage.
Although some studies have found low levels of BPA and phthalates in certain food containers, it is still best to exercise caution. By taking these precautions, you can help protect yourself and your family from the potential dangers of plastic exposure.

Avoid plastic water bottles
Plastic water bottles are a significant contributor to global plastic waste. They are used once and then discarded, with more than 80% of them ending up as trash. This leads to an average of 25 million tons of plastic waste each year, causing detrimental effects on the environment.
Choose Reusable Bottles
Opt for a reusable water bottle instead of single-use plastic ones. Reusable bottles are environmentally friendly, durable, easy to carry around, and cost-effective in the long run. Look for bottles made from food-grade stainless steel or glass, as these materials are non-toxic and easy to clean.
Use Tap Water
Unless your tap water is contaminated with unsafe elements, such as lead, it is generally recommended to drink tap water instead of buying bottled water. You can always filter your tap water to further reduce any potential microplastic levels.
Support Sustainable Businesses
Choose restaurants, cafes, or hotels that offer tap water or water in reusable containers. Support businesses that encourage the use of reusable water bottles, such as offering discounts or free refills for customers who bring their own bottles.
Carry Your Bottle
Get into the habit of carrying your reusable water bottle with you. This ensures that you always have access to clean water wherever you go, reducing the need to purchase bottled water. Most workplaces provide filtered water, so you can easily refill your bottle during the day.
Avoid Bottled Water at Events
When attending or hosting events, avoid distributing plastic water bottles to guests. Instead, offer water from pitchers or dispensers, and encourage guests to bring their own reusable bottles.
Remember, while it is important to reduce plastic bottle usage, it is nearly impossible to completely eliminate microplastics from your life. These steps will help reduce your plastic waste and contribute to a more sustainable future.

Buy food in glass containers
While it is impossible to completely avoid plastics and microplastics, there are some steps you can take to reduce your exposure to them through food. One of the most effective ways to do this is to buy food in glass containers or packaging.
Glass is a non-toxic and non-porous material, meaning it does not absorb stains, discolouration, or toxic chemicals, which can be harmful to your health. Glass is also easy to clean due to its non-porous surface, which prevents food particles from getting stuck and growing bacteria. Glass containers are also leakproof, making them perfect for storing food in the fridge or freezer, and they are safe to use in the oven and microwave.
Glass is also better for the environment. It is more durable and long-lasting than plastic, and it is 100% recyclable, reducing your impact on the environment. Glass containers can also be used for leftovers, unlike plastic containers, which can release chemicals when heated or frozen.
However, it is worth noting that not all food products are available in glass containers. Simple items like ketchup are often only available in plastic packaging. In these cases, it may be beneficial to transfer the product to a glass container once you get home to prevent further damage or leaching of microplastics.

Avoid fast food
While it is impossible to completely avoid plastics in food, there are several steps you can take to reduce your exposure to plastics and limit your consumption of fast food.
Firstly, it is important to understand that fast food is often heavily processed, packaged, and handled, which provides more opportunities for the food to come into contact with plastics and plasticizers. A study by George Washington University found that food items from popular fast-food outlets such as McDonald's, Pizza Hut, and Chipotle contained small amounts of industrial chemicals called phthalates, which are linked to serious health problems, including reproductive harm and learning problems in children. These chemicals can migrate into the food from sources such as food-handling gloves, industrial tubing, and food conveyor belts. Therefore, one way to reduce your exposure to plastics is to limit your consumption of fast food.
When you do eat fast food, be mindful of the packaging it comes in. Avoid plastic utensils, straws, and cups, which contribute to single-use plastic waste. Some fast-food chains, such as A&W, use recycled materials and compostable packaging, which is a step towards reducing plastic usage. You can also bring your own reusable cup and straw to reduce the amount of plastic waste generated.
In addition to avoiding fast food, you can reduce your exposure to plastics by choosing alternative materials for kitchen tools and food storage containers. Opt for wood, stainless steel, or silicone cutting boards instead of plastic ones, as chopping on plastic boards can generate microplastics that adhere to food. Avoid storing hot food in plastic containers or using plastic wrap, as heat can increase leaching of chemicals into your food. Instead, use glass or steel containers for storing leftovers and carrying drinks.
Finally, be mindful of your water consumption. Water from plastic bottles has higher levels of microplastics compared to tap water, so consider using a metal reusable bottle and filtering your tap water if needed. By combining these strategies, you can significantly reduce your exposure to plastics and the health risks associated with them.
