Often used to hermetically seal cooked dishes, prevent food oxidation and prevent the spread of odors, cling film is the subject of debate, particularly with regard to fatty foods. Explanations.
Plastic containers and cling film are essential allies in our kitchens. Ultra practical, they allow you to easily store food in the refrigerator and preserve their freshness.
The risks associated with plastic
Many experts advise against using plastic boxes or cling film to store foods containing animal fats, oils or nuts. According to the Franceinfo website, these products can release chemical substances, including bisphenol A (BPA) and phthalates, which are found in certain types of plastics. These substances, in contact with fats, could migrate into food, which raises concerns about their effects on health. BPA, in particular, is a known endocrine disruptor, meaning it can interfere with the body’s hormonal balance, mimicking the action of estrogen. Although health authorities, such as the Federal Office of Public Health (FOPH), indicate that no major health risks have been identified with current levels of exposure, the issue remains controversial, and some prefer to opt for safer solutions.
Safer alternatives
For those who wish to minimize risks, it is recommended to use glass or metal containers to store fatty foods, such as sauces or mayonnaise. These materials, more stable, do not present the same risks as plastic. Likewise, if cling film is used, it is best to avoid placing it in direct contact with food, particularly when heating it in the microwave. It should be noted that not all plastics contain BPA or phthalates. Plastics such as polyethylene (PE) or polypropylene (PP), commonly used to make containers and cling film, do not contain these substances.
