Microplastics are tiny particles resulting from the degradation of plastic. For several years, their presence in our environment has alerted researchers who are warning against this omnipresent pollution. If part of this contamination affects water, air or soil, our culinary habits must also be considered seriously, reports the online media Huffpost. From the choice of cutting board to the way you heat your dishes, every action counts to limit our exposure to these particles, the effects of which on health are causing increasing concern.
Cutting vegetables or meat on a plastic board releases, for example, microplastics which are found directly in the food. The stronger the cut, the more the quantity of particles released increases. According to a study, using plastic cutting boards could expose a person to up to 50g of microplastics per year. Therefore, choose wooden or bamboo boards, which are naturally non-porous and safer for your health.
Heating your food in plastic containers
Heating dishes in plastic boxes, even so-called “microwavable”, promotes the migration of microplastics into the food. One study showed that heating water in a plastic container could release more than 10 million particles into the liquid. Single-use packaging (yogurt pots, trays, bags of frozen vegetables) should be particularly avoided for cooking or reheating. Use glass containers suitable for the microwave or oven and always transfer your food to a bowl or plate before heating it.
Disposable storage bags: unsuspected sources
Freezer bags and other flexible plastic bags easily release microplastics, especially when opening or closing. This phenomenon is accentuated by repeated handling or cutting of plastic. Instead, opt for reusable silicone bags, glass or stainless steel boxes, or even beeswax packaging.
Plastic wrap and hot foods
Placing plastic film directly on hot food encourages particle migration, or even partial melting of the plastic on the food. This represents an additional danger, especially with moist or very hot foods. Choose aluminum foil (excluding microwaves, of course), glass lids or reusable silicone or beeswax films.
Plastic kitchen utensils
Cooking with plastic spatulas or spoons, especially on hot pans, causes microplastics to be released into food. Heat increases the degradation of plastic and the migration of particles. Prefer wooden or metal utensils, suitable for your pans and pots.
Plastic tea bags
Some tea bags contain polypropylene or nylon, which release millions or even billions of microplastics when steeped in hot water. These particles can enter the blood or digestive system. Prefer loose tea with metal or glass infusers, or choose bags guaranteed to be plastic-free, made of cotton, hemp or paper (be careful, some papers also contain plastic).
By changing a few simple habits, you will be able to significantly reduce the presence of microplastics in your diet and thus preserve your health and that of your loved ones.
