Plastic is everywhere in our lives, from the food we eat to the clothes we wear, and it is having a devastating impact on the environment and human health. Microplastics, tiny plastic particles less than 5mm in size, have been found in the lungs, blood, organs, and even the placenta of humans. They can also be ingested through food and water, with scientists estimating that we could be consuming the equivalent of a credit card's worth of plastic each week. The exact health impacts of microplastics are still being studied, but they have been linked to a range of worrying health issues, including inflammation, oxidative stress, disruption of hormonal balance, colon cancer, respiratory disease, and metabolic function issues. To avoid toxic chemicals in plastics, it is important to reduce plastic use, switch to non-plastic alternatives, and avoid heating or microwaving plastic.

What You'll Learn
Avoid eating food stored in plastic
It is important to avoid eating food stored in plastic to reduce exposure to toxic chemicals. Plastic food containers can leach chemicals into the food, especially if it is fatty or oily, as plastics are fat-soluble. These chemicals, such as BPA, phthalates, and bisphenols, are endocrine disruptors and have been linked to various health issues, including reproductive and fertility problems, behavioural issues, asthma, cancers, Alzheimer's, heart attacks, and infertility.
To avoid eating food stored in plastic, opt for fresh, whole foods or unwrapped items when possible. If buying packaged food, choose products stored in glass, stainless steel, or ceramic containers, and avoid single-use plastic packaging. You can also transfer food from plastic containers to metal or glass containers when you get home. When storing food at home, use glass, ceramic, wood, or stainless steel containers instead of plastic.
It is especially important to avoid heating food in plastic containers, as higher temperatures increase the likelihood of chemicals leaching into the food. This includes avoiding the use of plastic wrap, plastic cutting boards, and plastic baby bottles, as these can all shed microplastics into food or drinks. Instead, use reusable alternatives such as beeswax wraps, wooden or bamboo cutting boards, and glass or stainless steel baby bottles.
By making these small changes, you can significantly reduce your exposure to toxic chemicals in plastics and improve your health and the environment.

Avoid plastic wrap
Plastic wrap has been linked to various health issues, including cancer, problems in the reproductive organs, and behavioural problems in children. It is known to contain phthalates, which are endocrine disruptors, and in the US, plastic wrap is made of polyvinyl chloride (PVC) and contains a "plasticizer" called di(2-ethylhexyl) adipate (DEHA). DEHA is chemically similar to the phthalate DEHP, which has been shown to cause liver tumours in mice.
To avoid the potential health risks associated with plastic wrap, it is recommended to use alternative storage methods such as reusable glass or metal containers, beeswax wraps, aluminium foil, or parchment paper. These options are safer and more environmentally friendly than single-use plastic wrap.
When storing food, it is important to avoid allowing plastic wrap to come into contact with the food, especially when heating or if the food has a high-fat content, such as meat or cheese. Higher temperatures increase the likelihood of chemicals leaching from plastic, and heating food in plastic containers can accelerate the release of microplastics. Instead, use glass or ceramic containers for microwaving food and beverages, and cover food with a microwave-safe dish or paper towel to prevent splattering.
In addition to avoiding plastic wrap, it is also beneficial to reduce overall plastic use. Single-use plastics, such as grocery bags, plastic wrap, disposable cutlery, and straws, contribute significantly to plastic pollution. By choosing reusable alternatives, such as cloth bags, stainless steel water bottles, and bamboo utensils, individuals can play a crucial role in reducing plastic waste and its associated toxic chemical exposure.
Lastly, it is worth noting that while plastic wrap has been "phthalate-free" since 2006, some manufacturers outside the US may still use PVC in their products. It is always a good idea to be cautious and opt for alternative food storage methods whenever possible to minimise potential health risks.

Don't heat plastics
Heating plastics is a common practice in many households, especially when it comes to food storage and preparation. However, it is important to understand the potential risks associated with this practice to make informed decisions regarding your health and the environment. Here are some reasons why you should avoid heating plastics:
Chemical Leaching
When plastic is heated, it can release toxic chemicals that can leach into the food or liquid inside. These chemicals, such as bisphenol A (BPA), phthalates, and styrene, are known as endocrine disruptors. They can interfere with the natural balance of hormones in your body, leading to various health issues. For example, endocrine disruption has been linked to reproductive and fertility issues, behavioural problems, and asthma in children. The risk of chemical leaching increases when plastic containers are used repeatedly and start to show signs of wear and tear, such as scratches, pits, or discolouration.
Release of Microplastics
Heating plastics can also cause the breakdown of the plastic material into tiny microplastic particles. These microplastics can then contaminate your food or drink. Microplastics have been shown to absorb and accumulate toxic chemicals, including persistent organic pollutants (POPs) and heavy metals, from the environment. When ingested or inhaled, these microplastics can release these toxic chemicals into your body, potentially leading to adverse health effects such as inflammation, oxidative stress, and disruption of hormonal balance.
Toxic Gas Emission
According to a Nature article published in 2023, heating plastics to high temperatures, such as in a microwave, can result in the release of hazardous gases. These toxic gases can then mix with your food or drink, increasing the risk of various health issues. The risk of toxic gas emission is higher when plastic containers are old or damaged, as they are more likely to break down and release chemicals.
Alternative Options
To reduce the risk of toxic chemical exposure, it is recommended to use alternative materials for food storage and preparation. Glass, stainless steel, or ceramic containers are excellent options for storing and heating food. They do not leach chemicals, are generally safe, and do not pose the same health risks as plastics. Reusable containers made from these materials are also environmentally friendly, reducing the amount of single-use plastic waste. Additionally, when preparing baby formula, it is advisable to use a non-plastic container, allowing it to cool before transferring it to a sterilized and rinsed plastic bottle.
In conclusion, while heating plastics may be a convenient option, it is essential to consider the potential health and environmental risks associated with it. By understanding the dangers of chemical leaching, microplastic contamination, and toxic gas emission, you can make informed choices to protect your health and that of your family. Switching to alternative materials, such as glass or stainless steel, for heating and storing food is a safer and more sustainable option.

Avoid single-use plastics
Single-use plastics are a major contributor to the global plastic pollution problem. These plastics are meant to be disposed of after just one use and often end up in landfills or the environment, where they can take hundreds of years to degrade. To avoid single-use plastics, here are some instructive and focused tips:
Opt for reusable alternatives: Instead of using plastic bags, straws, bottles, and cutlery that will be thrown away after one use, invest in reusable options. This includes tote bags, stainless steel water bottles, bamboo utensils, and reusable straws. Make it a habit to carry these items with you when you go shopping, get takeout coffee, or eat out.
Reduce plastic packaging: Choose products with minimal or no plastic packaging. Buy whole foods or unwrapped items, and shop in bulk using your own containers. When buying packaged goods, opt for glass, stainless steel, or ceramic containers, which are less likely to contain harmful chemicals.
Cook more and store leftovers: Cooking from scratch reduces your reliance on takeout containers and disposable plastic packaging. Store leftovers in glass or stainless steel containers instead of plastic to avoid the risk of chemicals leaching into your food.
Avoid heating plastics: Do not heat food in plastic containers or wash plastic items in the dishwasher. Higher temperatures increase the likelihood of chemicals leaching from the plastic. Use glass or ceramic containers for heating and storing hot foods.
Be mindful of cosmetics: Cosmetics and personal care products often contain microplastics, which can be ingested or inhaled, potentially causing adverse health effects. Choose natural and plastic-free alternatives, and be cautious when selecting products.
Making these simple changes can significantly reduce your use of single-use plastics and decrease your exposure to toxic chemicals. It is important to remember that collective action is crucial in addressing the global plastic crisis.
