Many people may use plastic containers to heat up food in the microwave without thinking twice.
It seems convenient, but one leading scientist warns that it should never be done.
Dr. Shanna Swan, a well-known epidemiologist and health expert, strongly advises against it.
She made this statement during a discussion with scientist Andrew Huberman on the Huberman Lab podcast.
During their conversation, Huberman asked whether the "microwave safe" label simply means the plastic will not melt.
Dr. Swan did not hesitate. She firmly stated, "Never put plastic in the microwave."
Why is this so dangerous? Dr. Swan explained that plastic contains chemicals like BPA (Bisphenol A), phthalates, and plasticizers.
These substances are not tightly bound to the plastic, so they can easily seep into food when exposed to heat.
Phthalates are used to make plastic more flexible and durable. However, they have been linked to several serious health problems.
Studies have connected them to asthma, ADHD, breast cancer, obesity, type 2 diabetes, lower IQ, neurodevelopmental disorders, autism, behavioral issues, reproductive disorders, and male infertility.
BPA is another industrial chemical found in many plastic products, including food containers, baby bottles, and water bottles.
Research has associated BPA exposure with cancer, infertility, endometriosis, heart disease, obesity, and type 2 diabetes.
Plasticizers, which give plastic its elasticity, are also concerning. These chemicals can migrate into food when plastic is heated, adding another potential risk.
So, what should people do instead? Experts recommend simple changes to avoid exposure to these harmful chemicals.
Use glass or ceramic containers when heating food. Avoid plastic containers, even those labeled "BPA-free," as they may still contain similar substances.
Do not leave plastic water bottles in hot cars. Do not reuse plastic containers for heating food.
Dr. Swan's message is clear. For better health, people should stop heating food in plastic containers. Even if a product says "microwave safe," it is not worth the risk.
