Plastic is everywhere, and it's almost impossible to avoid consuming microplastics. However, there are ways to reduce your exposure to them. Microplastics have been found in the air, food, and water, and they come with unwanted guests: harmful chemicals that can impact human health. The production of plastics contributes to climate change, and the vast majority of plastic ends up in landfills, leading to an environmental crisis. To reduce plastic consumption, individuals can start by avoiding single-use plastics, choosing glass or stainless steel alternatives, and being mindful of how they store and use plastics.

What You'll Learn
Avoid single-use plastics at the grocery store
Plastic is a huge contributor to climate change, with its production accounting for 4% of global GHG emissions. If we continue on our current trajectory, this could triple by 2060. Single-use plastics are a significant part of the problem, as they are used once and then discarded, often ending up in our oceans and the bellies of marine animals.
- Get familiar with "naked" fruits and vegetables. Most fruits and vegetables are packaged in non-recyclable plastic, but they don't have to be. Many grocery stores sell fresh produce without any packaging, so look for these options when shopping.
- Buy in bulk. Many items, such as oats, rice, flour, salt, sugar, quinoa, beans, oils, and vinegars, can be purchased in bulk. This reduces the amount of plastic packaging used. Bring your own reusable containers to fill up, or use reusable bags.
- Reuse and recycle. Instead of always buying new products packaged in plastic, try to reuse and recycle the containers you already have. For example, wash and reuse glass jars from sauces and condiments. Also, choose products packaged in easier-to-recycle materials, such as glass, metal, or paper.
- Avoid pre-packaged foods. Many pre-packaged foods, such as chips, energy bars, and drinks, come in non-recyclable plastic. Look for alternatives that are packaged in recyclable materials or, better yet, bring your own reusable containers and fill up from bulk bins.
- Contact your grocery store. Write to your local grocery store and ask them to reduce their use of single-use plastics. You can explain how important this issue is to you and that you would like to see more products sold in bulk or packaged in recyclable materials.
- Support initiatives and policies. Support initiatives like the UN Global Plastics Treaty and the Break Free From Plastic Pollution Act, which aim to reduce plastic pollution. Also, vote for officials who prioritize sustainability and environmental protections, and support policies that ban or charge for single-use plastic bags.

Don't heat food in plastic
Heating food in plastic containers is not recommended due to the potential release of microplastics and harmful chemicals. When heated, plastics can leach chemicals such as bisphenols and phthalates, which are known as endocrine disruptors, into food. These chemicals have been implicated in various health issues, including diabetes, cancer, and obesity. Additionally, the presence of acidic or fatty foods can further facilitate the migration of molecules from plastic containers into the food.
To avoid this, it is advisable to use alternative materials for heating food. Glass, ceramic, or stainless steel containers are recommended for heating food in the microwave or oven. These materials do not release harmful chemicals when heated and provide a safer alternative to plastic. Glass containers are also preferred by some due to their rigidity and ease of stacking, although they can be more expensive and fragile compared to plastic.
It is worth noting that some people choose to continue using plastic containers for heating food, as they are lightweight and convenient for transporting meals to work or school. However, it is important to be aware of the potential risks associated with plastic and to make an informed decision. When using plastic containers, it is generally advised to avoid heating highly acidic or fatty foods, as these can increase the likelihood of chemical leaching.
To further reduce the presence of plastics in food, it is recommended to consume home-cooked meals prepared with fresh produce and whole foods. Ultra-processed foods often come into contact with plastic during manufacturing and are typically packaged in plastic as well. By choosing whole foods, individuals can reduce their exposure to potential plastic contaminants. Additionally, individuals can support initiatives such as the Break Free From Plastic Pollution Act, which aims to curb plastic pollution, and the UN Global Plastics Treaty, which addresses the impact of plastic pollution on human and planetary health.

Store food in glass, ceramic, or metal containers
Glass, ceramic, and metal containers are excellent alternatives to plastic for storing food. These materials are non-toxic, durable, and sustainable. They are also better at resisting stains and odours than plastic. Here are some tips for choosing and using these containers:
Glass Containers
Glass containers are a popular choice for those seeking a durable and sustainable option. They are easy to clean and do not retain odours or stains. However, glass containers can be heavier and more fragile than plastic ones. When choosing glass containers, look for those with airtight, locking lids to prevent bacteria and air from getting in. It is also important to note that glass containers are better suited for storing food in the refrigerator or freezer than for travel due to their weight and bulkiness.
Ceramic Containers
Ceramic containers are a great option for those who prioritize sustainability and durability. They are also naturally non-stick, so you won't have to worry about toxic chemicals like PTFE, commonly found in traditional non-stick kitchenware. When using ceramic containers, avoid extreme temperatures and sudden temperature changes, as this can cause cracking. It is also important to store ceramic containers carefully to prevent chipping and breaking.
Metal Containers
Metal containers, such as those made from stainless steel, are becoming increasingly popular for food storage due to their eco-friendly nature. They are odour-resistant, so you won't have to worry about lingering food smells. However, it is important to note that metal containers are not transparent, so you can't see what's inside, and they cannot be used in the microwave or oven.
Where to Buy
There are several options available in the market that offer glass, ceramic, or metal containers for food storage. Pyrex, for example, offers a 10-piece glass storage set with airtight, locking lids that are microwave-, oven-, dishwasher-, and freezer-safe. Caraway also offers a high-quality ceramic food storage set that is dishwasher-safe, oven-safe, and freezer-safe.

Avoid ultra-processed foods
While it is not necessary to cut out all processed foods, it is important to limit the consumption of ultra-processed foods. These foods are often shiny, packaged, and have nothing to do with nature. They are usually found in the center of the grocery store and include items like cookies, ice cream, soft drinks, and instant soups.
Ultra-processed foods are defined as "industrial formulations with five or more ingredients". They are altered from their original state and often have additives that imitate the flavor, color, or texture of less processed foods. These foods are also associated with an increased risk of health problems such as obesity, type 2 diabetes, heart disease, and cancer.
To avoid ultra-processed foods, it is recommended to eat home-cooked meals consisting of fresh produce and other whole foods. When shopping, avoid the center aisles of the grocery store, where processed foods are typically located. Instead, opt for the perimeter of the store, where fresh produce, meat, and dairy are usually found.
Additionally, when reading nutrition labels, be cautious of products with a long list of unrecognizable ingredients. This can be a sign that the food has been highly processed. Some ingredients to watch out for include added sugars, salt, oils, and fats, as well as stabilizers, preservatives, and additives.
By making conscious choices and opting for less processed alternatives, you can reduce your consumption of ultra-processed foods and improve your overall health.

Buy fresh produce from a farmer's market
Farmers' markets are a great place to start reducing plastic waste. Vendors at farmers' markets commonly wrap items in newsprint or place them directly into your basket or shopping bag. You can also buy free-standing fruits and vegetables and refrain from using plastic bags to store them.
When buying fresh produce from a farmers' market, bring your own bags and containers. Tote bags or woven mesh/net bags are great for carrying fresh produce. You can also bring your own containers, such as glass jars or metal containers, for items like cheese and meat. If you're buying meat, make sure your containers are sanitized for your safety.
Beeswax wraps are another option for wrapping cheese and meat products, and they can also be used for bread, shampoo bars, tea bags, and other dry items. You can also use tea towels sewn into bags to hold lettuce, carrots, broccoli, and other vegetables. These bags can be washed and reused, and they keep vegetables fresh for longer than plastic bags.
If you're buying bulk items like nuts, granola, flours, or seasonings, bring your own reusable bags or containers. Glass bottles are perfect for refilling items like shampoo, liquid soaps, and olive oil.
By bringing your own bags and containers, you can significantly reduce your plastic waste when shopping at farmers' markets.
