Microplastics Are a Hidden Health Problem

There is always something being posted about unhealthy things you should not eat. Let's look at some of these.

What is the problem with microplastics? Where do they come from? These are tiny, intentionally manufactured plastic particles, such as microbeads in cosmetics or industrial abrasives. They also result from the breakdown of larger plastic items—like plastic bottles, plastic we cook in, drink from, store foods in, plastic bags, and fishing nets. They also come from the use of microfibers made from plastic in clothing. Plastic objects degrade over time due to sunlight, water motion, physical wear, and other factors, becoming smaller and smaller particles. They become so tiny that we cannot see them. And microplastics never go away. hey cannot be broken down into "nothing".

What do these do to your body? Microplastics are a hidden health problem. They enter our bodies through the foods we eat and the air we breathe. They can enter your body through our skin. Many are excreted by the body, yet some remain in the blood, brain (highest concentrations), liver, kidneys, lungs, placenta, breast milk, and semen.

While in the body, these can cause inflammation & oxidative stress: Microplastics may trigger immune responses and cellular damage because the body is constantly trying to fight off foreign particles. Microplastics can cause endocrine disruption: Chemicals in plastics (like BPA and phthalates) can interfere with hormone function and cause organ damage. Animal studies show microplastics accumulate in the liver, kidneys, and even the brain. And all this can cause heart and kidney problems, cognitive decline, risks of cancer, and fertility problems. Most plastics take hundreds of years to degrade. We still do not know what specific health outcomes will be, as this is a relatively new area of study, but it can't be good.

Microplastics Are A Hidden Health Problem. How Can You Avoid Them?

Hopefully, baby boomers and subsequent generations are not of the mindset that we got ours; we were raised with disposable items, which made life easy—Tupperware, furniture, plastic packaging, and soda bottles. Will we ever find substitutes? Or are we going to keep making more and more plastic, compromising our children's health? When will we learn? Will we?

1. Skip Bottled Water: Bottled water often contains 6× more microplastics than tap water. Opt for NSF-certified filters to reduce microplastics in tap water. Especially don't drink from plastic bottles that have gotten hot: Heat can cause them to leach microplastics into water or soda. The longer and hotter the exposure, the greater the risk, especially for those left in cars, garages, or direct sunlight.

2. Avoid Plastic Food Containers: Microwaving in plastic can release billions of nanoplastics into food. Don't reheat food in these. Use glass, ceramic, or stainless steel for storage and heating. Avoid the plastic cups that you get drinks in at a restaurant or coffee shop. In fact, plastic cups containing hot liquids leach thousands of microplastic particles into your drink.

3. Limit Processed & Packaged Foods: Highly processed foods (such as fast food and snacks) may contain more microplastics due to packaging and production methods. Choose fresh, whole foods when possible.

4. Say No to Plastic Utensils & Takeout Containers: Plastic cutlery and containers can leach microplastics, especially when used with hot or acidic foods. Cook at home or use reusable alternatives, such as bamboo or stainless steel.

5. Watch Out for Synthetic Fibers: Microplastics shed from synthetic clothing and can contaminate food via household dust. Use natural fabrics and consider installing air purifiers or dusting frequently.

6. Even fruits and vegetables can absorb microplastics into their tissues, depending on soil and water contamination. Washing produce thoroughly and choosing organic or locally grown options may help reduce exposure.

7. Fish, shellfish, poultry, and meat accumulate microplastics through their feed, water, and soil, and they pass them on to us. You will never be able to avoid microplastics, but you can reduce your intake by checking out the sources of your food.
