Plastic blenders release billions of microparticles and nanoparticles of plastic into your food through mechanical abrasion, so it is recommended to switch to a stainless steel blender to avoid this contamination.

The idea that mechanical abrasion of plastic utensils releases microplastics is documented by polymer research, notably in studies published in journals such as 'Scientific Reports' that confirm the migration of particles during physical wear. The cited figure of '1 billion particles' comes from specific studies on the release of nanoplastics from various plastic materials under thermal or mechanical stress, which constitutes solid observational evidence of the phenomenon. However, labeling stainless steel as the only 'safe' option is a cautious interpretation rather than a clinical necessity, as the human health risks linked to the ingestion of these specific doses of microplastics remain largely debated and are not quantified by human clinical trials (RCT). It is accurate that the term 'BPA-free' does not guarantee the absence of other chemical compounds or particles, as plastic, by nature, can degrade over time and with heat. In summary, the risk of physical contamination is real and technically grounded, but the direct physiological consequences of this specific exposure remain an emerging field of science without established consensus.
