Scientists have extensively about the prevalence of microplastics and nanoplastics in the environment and in our bodies. Microplastics larger than a micrometre (1 millionth of a metre), while nanoplastics smaller than a micrometre. A new study has that bacteria from the fermented Korean dish kimchi can to nanoplastics from the body. Researchers at the World Institute of Kimchi in South Korea have a microbe that can itself to nanoplastics in the gut. The foreign body is then safely expelled in our bodily waste. The plastic does not through the intestinal lining and in organs like the brain, heart, kidneys, and liver.

Nanoplastics are of increasing concern to the medical community. There are many unknown side effects of these tiny particles in our organs. Current estimates people in up to 120,000 microscopic fragments every year. Newspapers often stories about our body containing 7 grams of plastic, which about the mass of a credit card. The Korean scientists their research might alleviate the accumulation of plastic in our bodies. Lead researcher Dr Se-hee Lee said: "Microorganisms from traditional fermented foods could a new biological approach to this emerging challenge. We will continue to the scientific value of kimchi."
