Terrifying Story: Human Body Has Microplastics
Putting aside the unreasonable parts and focusing only on the rational conclusions:
Microplastics are much like heavy metals—both can cross the blood-brain barrier, damage healthy cells, and accelerate cell death. Anyone who’s studied biology knows that heavy metals are key components of pesticides and cannot be expelled from the body. Microplastics behave similarly, though a portion can be excreted; the rest enters the bloodstream normally.
Main sources entering the human body:
On one hand, air pollution enters the bloodstream through breathing. On the other hand, and more significantly, they travel through the food chain—just like heavy metals. No one intentionally drinks pesticides or eats plastic, but the breakdown of biological waste and plastic garbage primarily releases these substances into water sources. Aquatic organisms are the first to be contaminated, and the toxins accumulate in their bodies, moving up the food chain to the top predators—humans.
This is one of the reasons behind the rise of various incurable diseases in recent years. Once these particles enter the body, they cannot be expelled and accumulate as toxins. (The so-called diseases of affluence are, to some extent, caused by consuming too many high-tier food-chain species, leading to a buildup of heavy metals and other indigestible particles in the body.)
From my personal perspective, eating less seafood can significantly reduce exposure to these micro-particles.
