Microplastics: are plastic alternatives any safer for our health?
AI summary Read the abstract
Researchers examined whether bioplastic food containers marketed as plastic-free alternatives actually reduce microplastic exposure, finding that knowledge gaps remain around the health impacts of bioplastics and that they may not be demonstrably safer than conventional plastics.
Alternative food containers, such as those made of bioplastics, are being promoted as a way to reduce our exposure to plastic in food. But there is still a lack of knowledge around their impacts.

Toxicity of microplastics in humans: A search for sustainable alternatives
AI summary Read the abstract
Researchers reviewed the toxic effects of microplastics on human respiratory, circulatory, and gastrointestinal systems, finding that particle size, shape, and surface chemistry govern biological harm. The review also evaluated bioplastics made from materials like corn starch and cellulose as sustainable alternatives, though it cautions that large-scale bioplastic production could strain global food resources.
Microplastics are everywhere — but are they harmful?
