Plastics may enter the brain by hijacking fats consumed in the diet.

This means that certain types of plastic particles, especially microplastics, can mimic or associate with lipids (fats) that are naturally present in our body. As the body processes these lipids, the plastics can potentially cross the blood-brain barrier, which is a protective barrier that selectively allows substances to enter the brain.

Plastics are found in major organs like the heart, lungs, and liver.

Research has shown that plastic particles have been detected not just in the skin and digestive system but also in significant organs, indicating that they circulate throughout the body and can accumulate in various tissues. This raises concerns about the potential health impacts on these organs.
