Millions of people around the world don’t think twice about a common cooking habit that a TV doctor has given up. Speaking on his No Appointments Necessary podcast with Cherry Healey, Dr Amir Khan said he is cautious about using plastic food containers or water bottles after studies showed a risk of microplastic contamination.

In an eye-opening conversation on his podcast, “No Appointments Necessary,” Dr. Amir Khan, a familiar face on ITV’s Lorraine and Good Morning Britain, has shed light on a common kitchen practice he’s decided to abandon. Joined by Cherry Healey, Dr. Khan expressed his growing concerns about using plastic containers and water bottles, following studies suggesting a risk of microplastic contamination.

Dr. Khan, a practicing general practitioner, stated, “With the information I’ve learned from the dementia and carotid artery studies, I’ve stopped using plastic containers. It’s not a guaranteed danger, but the possibility is enough for me to reconsider.” He emphasized that storing food in plastic can lead to the absorption of microplastics, which is further exacerbated when the containers are heated in a microwave, causing the plastic to destabilize and release harmful particles.

During the episode, Dr. Khan addressed the dilemma faced by many when it comes to cooking pre-packaged supermarket meals, typically encased in plastic. He recommended transferring these meals to a bowl or pan before heating, as a precautionary measure to minimize exposure to what he referred to as “microplastic central.”

What are microplastics? Why are they harmful?

Microplastics, defined as plastic fragments less than five millimeters long, originate from the degradation of larger plastic items or are intentionally manufactured for various products, including cosmetics and personal care items.

These tiny particles pose significant health risks, infiltrating crucial organs such as the blood, liver, and placenta. They can cause oxidative damage, chronic inflammation, and even cell death. Whether ingested through food and water or inhaled from the air, microplastics and their toxic additives have been linked to serious conditions like heart disease, cancer, reproductive issues, and metabolic disruptions.

How to avoid exposure to microplastics?

Microplastics are nearly impossible to remove completely once they enter the environment, making them a persistent global pollution issue. To avoid microplastics as much as possible, opt for using glass, ceramic, or stainless steel containers instead of plastic, especially when heating food.

Reduce the amount of bottled water, processed foods, and seafood in your diet. These often contain higher concentrations of microplastics.

Clean household dust frequently, as it often contains airborne microplastics. Wear clothes made of cotton, wool, linen, or hemp to reduce plastic fibres released during washing.

Research has revealed that those who drink bottled water on a daily basis ingest over 90,000 more microplastic particles than those who drink tap water. Experts are calling for urgent regulations to manage the risks associated with daily drinking habits.

The BBC suggested in a recent report to switch to reusable glass or stainless steel water bottles to reduce exposure. It claimed that a study found the simple act of screwing a plastic bottle cap on and off dramatically increased the amount of microplastics found in the water it carried.

With each twist on or off, it generated 553 microplastic particles per liter of water. Annelise Adrian, a senior programme officer with the plastics and material science team at World Wildlife Fund, said: “Studies are coming out showing that there are way more micro- and nanoplastics in bottled water than previously thought”.
