No, processed cheese doesn't contain actual plastic polymer, but it's called "plastic cheese" because its smooth, pliable texture and unique melting properties (due to added emulsifiers like sodium citrate and milk protein concentrate) make it seem plastic-like, distinct from natural cheese, which separates or oils when heated. However, studies do show microplastics and chemicals like phthalates can transfer from plastic packaging into cheese, especially during processing and storage, leading to contamination.
It's fine to consume processed cheese, but like everything in life, it's all about balance. You don't want to eat processed cheese all the time. Not only is it not the healthiest thing out there, but it backs you into a corner that's filled with one-noted cheeses.
Cheese is the easiest of the three dairy products to find without plastic. Most supermarkets will have a deli section, but if not, look for local independent stores, farmers markets, specialist cheese shops and other grocers. Some deli counters will have paper to wrap cheese, so you can ask for no plastic.
Which food contains the most microplastics?
Acceptable additives include acidifying agents, source of milkfat (cream, anhydrous milkfat, dehydrated cream), water, salt, artificial color, spices or flavorings (other than those simulating the flavor of cheese), and enzyme-modified cheese. PPC in consumer-sized packages can also include mold inhibitor and lecithin.
The unhealthiest cheeses are typically highly processed varieties like American cheese slices, spray cheese, and cheese spreads/dips, due to high sodium, preservatives, and unhealthy fats; however, rich, creamy natural cheeses like Brie, Camembert, and triple-crèmes are also high in saturated fat, making them less healthy in large amounts, with blue cheeses like Roquefort topping salt content. The "unhealthiest" depends on your health goal, but generally, processed versions offer less nutritional value and more additives than natural cheese, even high-fat ones.
Microplastics Can Be Flushed Out of Your System
“There is definitely reason to believe a lot of it will come out through the feces.” The chemicals from microplastics also “don't stay in the body very long, so if you stop exposure, the levels [in] your body will go down,” added Woodruff.
You may not realize it, but your morning cup of coffee could be another source of microplastics in food. Many coffee makers, particularly those with plastic components, can release these tiny particles during the brewing process.
Liu et al. (2022) quantified and identified the presence of microplastics in eggs using fluorescent microscopy and Fourier Transform infrared spectroscopy (FTIR), respectively. The study reported the presence of 11.7 ± 4.0 particles in eggs, with a higher count in egg yolks than in egg whites.
Ziploc storage bags contain polyethylene and polypropylene -- plastics known to release microplastics into foods when they're subject to extreme temperatures.
Any cheese with an ingredients list of only milk, salt, and enzymes/cultures (like cheddar, Swiss, mozzarella, gouda, feta, goat cheese, cottage cheese, etc.) is 100% real cheese, while "American Cheese" or "cheese products" often contain added emulsifiers and flavorings, making them processed rather than purely natural cheese. Always check the label: if it lists more than milk, salt, and enzymes (like sodium citrate, whey, artificial flavors), it's a cheese product.
Researchers in Italy's University of Padua detected plastic particles in nearly every dairy sample they tested, with the highest concentrations found in aged cheeses.

It is clear that mozzarella is one of the healthiest cheeses out there, not to mention flavorful too! This may just be one of the best low calorie cheese options overall. This high-protein low calorie cheese option is a smart choice for those focused on weight loss.
All-Bran, Bran Flakes and Weetabix are all high in fibre and contain a mix of important vitamins and minerals. They're classed as ultra-processed because they contain barley malt extract and/or glucose syrup. These are both types of sugar, but are present in relatively low amounts.
Examples of minimally processed foods
Here are some examples of common foods that have been minimally processed: Fresh and frozen vegetables and fruits. Grains (like rice and wheat berry) Legumes (like beans and lentils)
Notably, hot tea demonstrated the highest abundance of microplastics, with an average of 60 ± 21 MPs/l (n = 30, 1SD), compared to iced tea which had 31 ± 7 MPs/l (n = 10, 1 SD).
Sugar/Sugary Syrups
Adding sugar and sugary syrups to your coffee can lead to unhealthy spikes in blood sugar and excessive calorie intake, depending on how much you use. “One teaspoon of sugar in your cup of coffee will not have a giant impact on your overall health,” says Hollendonner.
If you want a safe cup for coffee, pick one made of glass, ceramic, or stainless steel. These materials keep you healthy because they do not let bad chemicals get into your drink. Studies say some paper cups can let out harmful things like arsenic and chromium into hot drinks. This can be dangerous.
Microplastics may cause changes in the intestinal microbiome, resulting in an imbalance between beneficial and harmful bacteria, which can lead to various gastrointestinal symptoms, such as abdominal pain, bloating, and changes in bowel habits.
Do Brita Filters Remove Microplastics? Brita filters can help reduce some microplastics, but they do not remove all of them.
Here's some suggestions for how you can reduce your intake of microplastics:
Bega Cheese typically contains healthy fats but is relatively high in saturated fat and sodium, so moderation is recommended for individuals monitoring their heart health. With minimal additives and preservatives, it maintains a naturally wholesome profile.
Cottage cheese
A soft white cheese made from the loose curds of cow's milk, cottage cheese has a unique protein-to-calorie ratio. It's this high protein combined with low calorie content that makes cottage cheese a good choice for weight management, with studies suggesting it may even be as satiating as eating an egg.
Feta also has potential health benefits; it supports bone health with calcium and phosphorus, and its probiotics may aid gut health. However, its high sodium can raise blood pressure, and its saturated fats should be limited. Enjoy feta in a range of recipes, from salads to pizzas.
