BPA Stops Your Brain From Growing New Neurons

Your brain grows new neurons throughout your life, a process called neurogenesis. BPA blocks it. The plastic chemical jams the transport system that moves mitochondria (cell energy sources) to where they're needed in brain cells.

What the Study Found

A 2026 study in the Journal of Biological Chemistry discovered that BPA impairs hippocampal neurogenesis by disrupting Kinesin-1-dependent mitochondrial trafficking. Kinesin-1 is a motor protein that moves mitochondria along the cell's internal highway. BPA breaks this system.

Without proper mitochondrial delivery, new brain cells can't form or survive. The hippocampus is the brain region responsible for learning, memory, and emotional regulation. Less neurogenesis there means worse memory, slower learning, and increased risk of depression.

BPA Is Still in Everything

Despite partial bans, BPA remains in food can linings, plastic containers, water pipe linings, dental sealants, and thermal receipt paper. Most adults have detectable BPA in their bloodstream right now.

What You Can Do

Eliminate plastic food containers from your kitchen. Avoid canned food and drinks. Use glass, stainless steel, or ceramic. Don't handle thermal receipts. Every bit of reduced exposure helps your brain keep doing its job.
