Microplastics have already been found almost everywhere – In the air, in water, in food and even in the human body. Studies in recent years indicate that these tiny particles may accumulate in various tissues in the body and even in the brain. Now a new study suggests that a fermented and popular food may help the body get rid of some of them.
Microplastics are tiny plastic particles, up to five millimeters in size. They are mainly created from the breakdown of larger plastic products over time, but some are produced in advance as part of everyday products such as cosmetics, cleaning agents or toothpastes.
According to researchers’ estimates, tens of millions of tons of microplastics are released into the environment every year, and the amount may even double by 2040.
These particles have already been found in food, in beverages, in clothing and even in the air we breathe. When they enter the body, they may accumulate in various tissues, including in the reproductive system and in brain tissues. There are even estimates according to which an average person may ingest an amount of microplastics equal to the weight of a credit card every week.
Various studies have also raised concern that exposure to these particles may affect biological systems. For example, it was found that marine animals and birds exposed to microplastics may be more sensitive to infections.
The food that may help remove particles from the body
A new study published in the scientific journal Bioresource Technology found that kimchi, a fermented Korean food based mainly on cabbage and other vegetables, may help remove tiny plastic particles from the body.
According to the researchers, lactic acid bacteria found in fermented foods like kimchi can bind to nanoplastics – Especially small particles of microplastics – In the digestive system. This binding allows the particles to aggregate and be expelled from the body through the digestive system.
Kimchi has been considered for years a food with various health benefits. It is a fermented food rich in dietary fiber and probiotic bacteria, which contribute to digestive system health.
What else does kimchi do?
Various studies link the consumption of kimchi to additional possible benefits, including:
Improvement in digestive system activity
Assistance in regular bowel activity
Support for heart health
Reduction of the risk of certain diseases in the intestine
How to incorporate kimchi into the menu?
One of the advantages of kimchi is its culinary flexibility. It can be eaten as it is as a small snack alongside a meal, but also incorporated into a variety of dishes.
Among the popular options:
Adding to an omelet or to scrambled eggs
Combining in fried rice or in noodle dishes
Adding to grain bowls such as quinoa with vegetables
Incorporating in salads or as a side dish
Despite the interesting findings, the researchers emphasize that this is an initial study in the field, and that further studies are needed to better understand the effect of fermented foods on the removal of microplastics from the body.
