It seems to be a common theme in history that the things that lead to great progress and convenience also come with a big price. This seems to be very much true with plastic products and packaging.
There is no denying that inexpensive plastics have made many aspects of food and water distribution much easier (though I would argue that this is problematic as well), but emerging research and data from decades of increasing use of plastics suggest that we need to seriously reevaluate our plastic usage.
Personally, I’m convinced that our health and the health of our planet would be much better off if we drastically reduced our use of plastic. Here’s why:
Health Problems with Plastic
Certain chemicals in plastics, like Bisphenol-A (BPA), have gotten media exposure for their potential health problems but there’s much more to the problem that a few isolated chemicals.
BPA
BPA is often added to plastics to make them more durable, but it was once given to animals like cows and chickens to cause them to gain weight before slaughter. BPA is known to disrupt hormones and can mimic the effect of estrogen in the body, leading to weight gain and hormone imbalance.
From The Journal of the Yale School of Environmental Studies:
There is also now abundant research that links BPA and phthalate exposure to such human health concerns as deformities of the male and female genitals; premature puberty in females; decreased sperm quality; and increases in breast and prostate cancers, infertility, miscarriages, obesity, type 2 diabetes, allergies and neurological problems, like attention deficit hyperactivity disorder.
It is widely known that plastics from food packaging can leach into food and enter the body. The CDC reports that over 92% of people who were tested had detectable levels of BPA and other plastic chemicals in their bodies (including newborn babies).
“Estrogenic chemicals found in many common products have been linked to a litany of problems in humans and animals. According to one study, the pesticide atrazine can turn male frogs female. DES, which was once prescribed to prevent miscarriages, caused obesity, rare vaginal tumors, infertility, and testicular growths among those exposed in utero. Scientists have tied BPA to ailments including asthma, cancer, infertility, low sperm count, genital deformity, heart disease, liver problems, and ADHD. “Pick a disease, literally pick a disease,” says Frederick vom Saal, a biology professor at the University of Missouri-Columbia who studies BPA.”
Phthalates
Phthalates are also found in many plastics and in high levels in indoor air. The European Union banned them in 2005 and many other countries have banned them as well.
Phthalates are considered to be especially harmful to men and boys, especially those exposed in utero. They are linked to immune system impairment, reduced testosterone, infertility in men and many other problems.
Plastics and the Planet
To go all Captain Planet for a minute, plastics are literally taking over the earth at a terrifying rate.
Dr. Alan Christianson, an expert in endocrine health, speaks the drastically rising rates of obesity in humans and in many other animal species (including wild animals whose diets have not changed). In his upcoming Adrenal Reset Diet book (I highly recommend it), he explains how many factors can contribute to these problems, but that they all share the trait of negatively affecting the endocrine system, especially the adrenals.
The chemicals in plastics are known endocrine disruptors, and this common thread may explain why we are seeing these problems in many species of animals around the world.
When we consider how long it takes for plastic to break down, and the high levels of plastic pollution found even in areas not inhabited by humans (like the ice and water of the Antarctic), we can start to understand how big of a problem plastic pollution can be.
UV light and the salt in seawater cause microscopic particles of plastic to emit toxic chemicals such as PCBs and DDT. When ingested by many types of marine species, these can be mistaken for estradiol, a sex hormone, causing a variety of symptoms related to endocrine disruption. Additionally, the chemicals tend to bioaccumulate in organisms as they move up the food chain, and can eventually lead to tainted populations of fish that humans regularly consume.
These sorts of problems have led Charles Moore, an oceanographer and racing boat captain who played a significant role in discovering and publicizing the great Pacific Garbage Patch, to argue that plastic pollution has become a more urgent problem for ocean life than climate change. “The sad thing is we thought Antarctic waters were clean,” he told the Australian Associated Press after the Tara‘s findings were announced. ”We no longer have an ocean anywhere that is free of pollution.”
With widespread plastic usage, it is likely that these problems will only get worse. Reuseit.com reports that:
• Over 1 trillion plastic bags are used every year worldwide. Consider China, a country of 1.3 billion, which consumes 3 billion plastic bags daily, according to China Trade News.
• About 1 million plastic bags are used every minute.
• A single plastic bag can take up to 1,000 years to degrade.
• More than 3.5 million tons of plastic bags, sacks and wraps were discarded in 2008.
• Only 1 in 200 plastic bags in the UK are recycled (BBC).
• The U.S. goes through 100 billion single-use plastic bags. This costs retailers about $4 billion a year.
• Plastic bags are the second-most common type of ocean refuse, after cigarette butts (2008)
• Plastic bags remain toxic even after they break down.
• Every square mile of ocean has about 46,000 pieces of plastic floating in it.
Plastics are widely considered safe by regulatory agencies, but not because they have been tested and proven to be safe. In most cases, this just means they have not been tested at all or that industry sponsored tests have shown them to be safe in small levels.
Where are These Most Commonly Found?
Different types of plastic chemicals are found in various types of plastics. This chart from the Ecology Center shows some of the most common chemicals and their sources:

The documentary Unacceptable Levels points out many of the most prominent sources of plastic pollution in our homes.
I know some people reading this are defaulting to the “oh please, everything is going to kill us anymore, this is just alarmist and fear inducing,” mindset, and I don’t blame them. It is hard not to feel like everything is out to get us sometimes, but I truly believe that plastic exposure might be the “cigarettes” of our generation.
It was once considered absurd that smoking could be unhealthy, and there were even campaigns claiming that more doctors preferred one brand of cigarettes to another. Soda was once marketed as a healthy drink for small babies. Regulatory agencies once considered now-banned chemicals like DDT safe for use and there were even ad campaigns promoting their usage around children.

We now look back and laugh at the idea that smoking is completely safe and laugh… perhaps that is how we will think of plastic in just a couple of decades. (Update: A reader brought to my attention that the soda ad was actually a hoax designed to make fun of other poor advertising from that time- though I found it used as an example of vintage advertising on several reputable sites. I have verified the authenticity of the other two ads and decided to leave the soda ad but disclose this information)
What Can We Do?
Unfortunately, plastics take a really long time to break down and the high levels of plastics in landfills, oceans and even remote areas of the planet paint a rather bleak picture of the future for plastic pollution.
One big thing we can all do is to reduce the amount of plastic products we are buying and using. This will reduce our own exposure to plastic pollution, our planet’s plastic load, and will often save money as well. Some great ways to reduce plastic exposure:
- Start using a glass or stainless steel water bottle in place of disposable plastic water bottles (this is my favorite). Even better, fill your water bottle from a re-usable stainless steel water filter that will also help reduce chemical exposure from water.
- Switch to reusable grocery bags instead of plastic or paper bags. These are widely available at many stores or you can make your own from old t-shirts. Bring lightweight mesh bags to the store to use for produce.
- Stop buying processed foods that are packaged in plastics. This is a huge step for your health on its own, but it will also reduce the amount of plastic waste we produce each year. Shop at farmers markets and use reusable bags. If it is in a plastic bag or a box, just don’t buy it.
- Replace plastic bags and plastic food storage containers with safer reusable options. Plastic bags, plastic wrap and thin plastic storage containers are major sources of plastic exposure. Switch to glass or stainless steel for storage, or use an unbreakable option like silicone. I like this silicon storage available here (use the code WMX10 to get 10% off). You can even make your own reusable snack bags.
- Buy wooden or metal toys for children instead of plastic. (They last longer too!)
- Bring your own glass/metal bottle or thermos when buying drinks away from home. Don’t get takeout food in Styrofoam containers which are a major source of plastic chemicals and waste.
- Consider using cloth diapers instead of disposable. Here’s what we use.
- Use glass and metal dishes, silverware and bakeware in place of plastic.
- Recycle whatever you can!

I had another wake up call about plastics after I purchased a box of unbleached wax “sandwich” bags. I was really trying to reduce our plastics exposure, but to my dismay I realized that I was transferring everything FROM plastic (nuts, for example) into these wax bags. I guess I have more work to do. I am pretty motivated though. I am very interested in endocrine health for my family. Will certainly check out Dr. Christianson’s book!
Thanks so much for this article, Katie. Here in California plastic shopping bags were just outlawed which is a good first step, I’d say. I’m curious, though, what to use in place of plastic wrap and dog cleanup bags – which in a big city are sort of a must-?
We use old newspaper or magazine or old books we don’t read instead of just throwing it. Hope it helps.
Would you consider using BPA-Free plastic bottles instead of ordinary plastic bottles?
Most research I’ve seen is now showing that BPA free isn’t a good alternative either since the BPA is just replaced with another chemical that can also be harmful. I’ve used glass or metal bottles.
What can you use as an alternative for baby bottles and nipples?
There are glass or metal bottles and natural rubber nipples.
Do you have product suggestions for packing school lunches in, instead of plastic containers? Also, sippy cup suggestions for toddlers that are not plastic? We have thermos stainless cups but the straw piece is very difficult to get clean.
Thank you!
This was a great post! Thanks as always for all of the helpful information 🙂
I have a random question that I have been meaning to ask. My fiance and future in-laws LOVE restaurant food (as do I), and while we are grain free diet at home, it is SO hard when we go out. Do you have any suggestions on what to eat at restaurants while still remaining healthy and on the diet? Thanks!
Also…do you have any good recommendations for a substitute for tortilla chips? I can’t get my fiance to stop eating them! I am so tired of nagging him LOL
-Elle 🙂
For chips, I like kale chips or cheese chips. When eating out, I like sushi (although it still has rice unless you actually get sashimi). I hear Brazilian-style steakhouses are a dream come true for real food lovers, but I haven’t been to one myself. Supposedly it is one big parade of high-quality meat with a generous salad bar thrown in for fun. I love Italian food but it is hard to find Italian (restaurant) food that is grain-free.
I’ve tried the kale chips but mine just haven’t turned out right – yet.
But recently tried the cheese chips & love ’em. – Maybe it’s a good thing I only recently found the recipe for ’em -…. lol
By accident I found that a little bit of the cheese chips were left on the plate after I had sliced a Green apple onto it – and one slice tasted really good – then I found out that it was the partial cheese chip that was so good with the apple.
So I sliced another apple (later) and put cheese on top of each. This time I didn’t let the cheese get ‘crispy’ as i should have – so next time I plan to put the cheese first then cook until about ready then put the slices of apple on top before cooking longer. I think I’ll prefer the crispy apple (not cooked so much) with the crispy cheese chips – I’ll figure it out….
And just FYI – I have found that using the Toaster Oven is fantastic for baking snacks or just a little bit of anything (I’m single so this works great) – such as zucchini pizza bites which I eat a lot of now.
check out Beanitos chips. – check the ingredients to make certain you can eat them – they change per different type of chips.
But they are made from beans – so don’t over-do or you’ll get the same ‘reaction’ as when you eat beans… lol
At most restaurants I find they will allow for substitutions, so that I end up with a protein and lots of vegetables. The only aspects I still have little to no control over are what kind of oils the foods are cooked in and likelihood that meats are factory farmed.
Cauliflour chips!!! So much better than tortilla chips!
We love buying frozen fruits and veggies to have in fridge whenever we need them, but they are all in plastic bags..what do you suggest? Buy fresh then freeze?
Yes.
I’ve tried various frozen fruit brands but found that they just don’t taste like the ‘real’ thing to me – so i’ve stopped buying frozen fruits. And can’t remember when I last bought frozen veggies.
As for fruit or veggies – I freeze if not eaten soon enough. And they taste so much better than the typical frozen varieties in grocery stores.
We’ve been using mason jars in our home instead of plastic bottles and tumblers. I love how rustic they feel and knowing that I’m not poisoning myself OR the environment. <3.
I have recently begun using mason jars for storing so much of my ‘stuff’ – seeds, nuts, xylitol, quinoa, etc. and my fresh juices from my juicer & different left overs, etc. – They are higher and not spread out like the usual bowls I had always used before – so can put more in the frig or cabinets.
EVERYTHING tastes better if you drink it out of a mason jar!! Especially milk.. Yummy! How I miss drinking milk..lol
Thank you for such a great article. The use of plastic nowadays is almost used in everything and it is so easy to obtain as well. Even warming up food in plastic is not good either as well as the styrofoam, as mentioned in the article. In addition, the investment of purchasing reusable bags helps the environment and pays off in the long run. I have also found it to be so useful because some stores give incentives to use the reusable bags by reducing a small amount off your bill, which pays off in the long run and saves money as well. I thoroughly enjoyed this post. A great reminder in evaluating what we use daily and what we take for granted.
Going plastic-free seems overwhelming at this moment, so perhaps a little at a time. I have two questions:
1. We buy a lot of milk in plastic 1-gallon containers. I don’t see our family of 8 going without milk, so what could be some alternatives there?
2. What are your thoughts on simply using non-BPA plastic, for food storage and such?
1. We get milk from local farmers if we get it- it comes in glass jars and jugs and we return them each week. This reduces a lot of waste as well.
2. Some are decent, but most just replace the BPA with another harmful chemical. We use silicon, metal or glass for storage.
I agree – drinking milk straight from the cow is the best milk. Also using glass jars/bottles is also how we got our milk while I was growing up – & straight from the cow… – not that watered-down stuff they have at grocery stores today.
I thought that was illegal. None of the farmers around here do it…
Is silicone free of all harmful chemicals?
I wrote about it silicone here: https://wellnessmama.com/25952/silicone-safe-for-baking/
