Studies have revealed that microplastics are present in various food and beverages, particularly seafood. The rise in plastic production since the 1960s has led to about eight million metric tons of plastic entering the oceans yearly. This plastic breaks down into tiny fragments known as microplastics due to sunlight degradation and wave action.
According to environment expert Catherine Rolph, microplastics are not limited to seafood but can also be found in other food sources. Research indicates that individuals may intake between zero and 1.5 million microplastic particles daily from food and drinks. Rolph has identified five surprising food items known to contain microplastics.
For instance, chewing gum is a significant source of microplastics as the gum base releases these particles when chewed. Similarly, salt products have been found to be contaminated with microplastics, with terrestrial salts showing higher levels of contamination than marine salts. Furthermore, tea leaves, coffee, and milk can all be sources of microplastic contamination.
Rolph emphasizes that storing food in plastic containers and consuming highly processed foods are associated with high microplastic concentrations. She suggests switching to glass containers and using glass instead of plastic for microwaving food to prevent microplastic leaching. Additionally, she recommends opting for tap water over bottled water to reduce microplastic exposure.
While completely eliminating plastics from diets may be challenging, making these adjustments can help reduce exposure to microplastics.
