Chemicals like BPA and phthalates are often discussed because they may interfere with hormones in the body. These effects can be especially concerning for children, since hormones play an important role in growth, puberty, metabolism, and development.
The risk does not always require plastic to melt or visibly warp. Heat alone can increase the chance that chemicals move from the container into food over time, especially with repeated use.
A safer habit is to use glass, stainless steel, or ceramic containers for heating and storing warm food. Plastic can still be used more cautiously for cool, dry foods, but avoiding heat exposure is one of the simplest ways to reduce possible risks.
