Microplastics have become a significant concern as studies suggest that people consume between 39,000 and 52,000 microplastic particles annually, with the number increasing to 74,000 to 121,000 particles when considering those breathed in. A recent study found microplastic shards in human brain tissue, raising questions about the potential risks. While there is no officially established “safe” level of microplastic intake, it is advised to minimize exposure as much as possible. Various ways microplastics can end up in food include contamination during agriculture, irrigation with contaminated water, and plastic packaging. The most common foods that contain microplastics include seafood, tea bags, rice, salt, sugar, bottled water, honey, fruits, vegetables, and proteins.
Seafood is a significant source of microplastics due to single-use plastics breaking down in waterways and soil, ultimately ending up in the ocean and being consumed by fish. Tea bags can release plastic particles when in contact with hot water. Rice, salt, sugar, bottled water, honey, fruits, vegetables, and proteins have all been found to contain microplastics, posing potential health risks. Ways to reduce exposure to microplastics in food include washing rice, choosing glass or cardboard packaging for salt and sugar, drinking tap water from stainless steel or glass containers, buying honey from local beekeepers, washing fruits thoroughly, peeling when possible, and opting for local or organic produce.
It is essential to be cautious and make efforts to reduce intake of microplastics in food. Avoiding plastic-containing food storage containers, plastic-wrapped foods, and plastic kitchen utensils can help minimize exposure. Installing a filter in a clothes-washing machine to catch microfibers and prevent water pollution is another way to address the issue. While more research is needed to understand the long-term implications of ingesting microplastics, it is recommended to maintain a balanced diet of protein, fruit, and vegetables to ensure the body has sufficient nutrients to function well. Despite the presence of microplastics in various foods, it is still possible to eat healthily by making mindful choices and taking proactive steps to reduce exposure where possible.
