Plastics are made up of tiny particles called microplastics and even smaller particles called nanoplastics. These particles have entered our food chain and pose health risks. When ingested, they end up in the digestive system, where they can be absorbed into the bloodstream and even reach the brain. They also target the endocrine system, which can interfere with hormones. The brain has the highest number of microplastics than any other organ. Microplastics are linked to disruptions in reproductive, developmental and immune systems, which can contribute to cognitive and behavioral issues. They can also increase the risk of certain types of cancer and cardiac disease.
The most significant source of microplastics in the food supply is in seafood, as fish will ingest them mistaking them for food particles. Other sources of microplastics are in bottled water and foods stored in plastic containers.
So, what can we do? We can drink bottled water from glass containers or use a water filter, consume smaller fish such as sardines and anchovies, and minimize buying food in plastic containers and heating food up in these containers. Making these small changes can help protect both our health and the environment.
