A spoonful of microplastics in your brain?

The latest headlines are alarming: adult human brains now contain the plastic equivalent of a disposable spoon. Yikes.

In a world filled with plastic, it’s no surprise tiny particles of the stuff are showing up in unexpected — and unwanted — places. As awareness about the presence of microplastics grows, so does concern about their potential health effects. Here’s what you need to know.

Microplastics are exactly what they sound like: tiny particles of plastic, usually under five millimeters in size. There are two broad categories; primary microplastics are intentionally small (like exfoliating beads and synthetic fibers), while secondary microplastics are formed when larger plastic items break down over time.

Microplastics have been detected everywhere from oceans and soil to drinking water to human tissues.

Microplastics enter the body in three ways: ingestion, inhalation and absorption through the skin. Our modern world makes them tricky to avoid; drinking bottled water, eating foods packaged in plastic and wearing synthetic materials can result in exposure.

Not only are microplastics a form of environmental pollution, but ongoing research suggests links between ingestion of microplastics and negative health impacts.

More studies in humans are needed to draw definitive conclusions about the effects of microplastic exposure. So far, data suggests the ingestion of microplastics might upset the delicate balance of bacteria in the gut, which could have far-reaching health implications.

Signs of gut dysbiosis can include digestive discomfort or irregularity, food sensitivities, weakened immunity and unexplained fatigue. Limit your microplastic exposure and fortify your foundational health with these practical tips.

→ Store food and beverages in glass or stainless steel containers

→ Limit highly processed foods packaged in plastic and opt for fresh, whole foods instead

→ Choose sustainably sourced seafood and clean it thoroughly before cooking and eating

→ Cook more of your meals at home to avoid plastic takeout materials

→ Improve your health at the foundation with nutrients like Urolithin A, scientifically shown to improve cellular function
