Can phthalates in plastic change your baby's brain chemistry?
Yes. A 2025 study found prenatal DEHP exposure alters glutamatergic proteins in the hippocampus of offspring, affecting learning and memory circuits.
What's actually in it
DEHP (di-2-ethylhexyl phthalate) is a plasticizer found in PVC flooring, food packaging, medical tubing, and children's toys. It crosses the placenta and reaches the developing brain. The hippocampus, which controls learning and memory, is one of the most sensitive brain regions.
What the research says
A 2025 study in IBRO Neurosci Rep found that prenatal DEHP exposure altered glutamatergic protein associations in the hippocampus of male rat offspring. These proteins control excitatory brain signaling critical for learning and memory.
Avoid PVC products and food stored in soft plastic containers. Choose glass and stainless steel for food storage.
