Microplastics

Microplastics are tiny plastic particles now found in water, food, air, and human tissue. Long-term human health research is still young, but Ray Peat treated their small particle size itself as a meaningful concern.

Peat's view

Asked directly about reducing microplastic exposure and whether ingested microplastics behave like raw starch granules in the gut, Peat pointed to filtration and flagged a specific mechanistic worry about particle size:

Reverse osmosis is the most effective practical way to filter water. Nanoparticles enter cells more easily than starch granules.

— Ray Peat

That last point matters because starch granules can themselves be absorbed intact into the bloodstream under some conditions (see Safe starches); Peat's point was that plastic nanoparticles cross into cells even more readily than that.

Practice

Reverse-osmosis water filtration where practical; avoid heating food in soft plastic, which increases particle and chemical migration into food. See Water, Harm reduction.
