I prefer it more as discomfort food.
A recent collection of four papers published in the Journal of Brain Medicine highlights concerning connections between microplastics, ultra-processed foods (UPFs), and mental health.
Ultra-processed foods are often regarded as unhealthy, largely because they typically contain high amounts of sugar, saturated fats, and sodium. Examples include soft drinks, chips, chocolates, ice creams, processed meats, many ready-to-eat meals, and mass-produced cereals.
While prior studies have indicated that people consuming UPFs face a notably increased risk of depression, anxiety, and sleep issues, the potential impact of microplastics in this scenario hasn’t been adequately explored.
These ultra-processed items are particularly vulnerable to contamination by microplastics, primarily due to their packaging, additives, and the production methods involved.
The researchers cited chicken nuggets as an instance, noting they contain over 30 times more microplastic than actual chicken breast.
“We observe converging evidence that should concern us all,” remarked Dr. Nicholas Fabiano, a psychiatry resident at the University of Ottawa in Canada.
“Currently, ultra-processed foods constitute more than 50% of energy intake in places like the U.S., and these foods have significantly higher microplastic concentrations compared to whole foods,” he added. “Recent findings suggest these particles can cross the blood-brain barrier and accumulate in substantial amounts.”
This could even shed light on the recent striking news that microplastics may be present in our brains in considerable quantities.
“We’re at a pivotal point,” noted Dr. Wolfgang Marx, a senior research fellow at the Food and Mood Centre at Deakin University in Australia.
“Ultra-treated foods are linked to negative mental health effects through mechanisms like inflammation, oxidative stress, epigenetic changes, mitochondrial dysfunction, and disruptions to neurotransmitter systems,” he continued. “Microplastics seem to operate through similar pathways.”
While further investigation is crucial regarding the microplastics-mental health link, the existing evidence is certainly eye-opening.
“It’s vital to delve deeper into this potential connection, especially as the rates of ultra-processed food consumption, microplastics, and mental health issues continue to rise,” Fabiano highlighted. “After all, you are what you eat.”
How to minimize microplastic exposure
- Avoid using plastic containers for microwaveable food, as this can release millions of microplastic particles into your meals.
- Opt for glass or metal containers, which are better suited for food storage and preparation.
- Reduce consumption of UPFs: Try to choose whole, unprocessed foods whenever possible.
- Filter tap water to help decrease microplastic intake.
