How Strict Rules on Sourcing Dairy Proved impossible — and Would Have Hurt Reproducibility As Well

Dairy has many opportunities for plastic contamination For dairy products, we created an ultra-strict sourcing protocol that assumed that the introduction of plastic chemicals into the dairy food chain begins with the milking process. That strict protocol had to be drastically altered will be described below. To consumers, the most obvious connection between plastic and […]

Why we did not include plant based milk substitutes

Plant-based milk — while growing rapidly — represents only 15% of milk consumption (Nielsen data) and is therefore not yet part of the typical American diet. Even more importantly for this study, plant-based milk substitutes are ultra-processed, industrially synthesized products which involve substantial contact with plastic chemicals. In addition to being a typical part of […]

Best practices – Baking powder versus yeast

Commercially purchased bread has numerous plastic contamination routes in preparation and packaging — some known and probably others unknown. Best kitchen practices, therefore, demand that bread be baked from known ingredients. One of those ingredients a rising agent — yeast or baking powder. Because investigators could not determine the provenance of yeast — processing and […]
