Dietary interventions as now conducted are incapable of rendering valid causal conclusions about specific substances, compounds, or chemicals. This is because the near-infinite variations in foods produce unknown and unknowable co-contamination errors that are further confounded by preparation inconsistencies.

Dosing of a Single Compound to Establish Causality in Dietary Interventions & Enable Clinically Valid Health Decisions
“Inconsistent and contradictory results from nutrition studies conducted by different investigators continue to emerge, in part because of the inherent variability of natural products, as well as the unknown and therefore uncontrolled variables in study populations and experimental designs.” — The Challenge of Reproducibility and Accuracy in Nutrition Research: Resources and Pitfalls This ad-free article […]
How Does the Food Chain Get Contaminated with Plastic-Derived Chemicals (PDCs)?
BPA & phthalates (and other plasticizers) migrate, leach, and flake from plastics BPA & phthalates migrate, leach and flake off of plastics primarily because they are not chemically bound to the plastic.

Micro- and Nanoplastics: Health Implications
This ad-free article is made possible by the financial support of the Center for Research on Environmental Chemicals in Humans: a 501(c)(3) non-profit. Please consider making a tax-deductible donation for continued biomedical research. Microplastics are generally those fragments that are less than five millimeters in size. However, a single microplastic fragment rarely stays the same size. Whether […]
How Food Processing Adds Plastic-Derived Chemical Contamination
According to How does the food chain get contaminated with plastic-derived chemicals?, plastic-derived chemical (PDC) contamination of basic foods, even those that do not undergo extensive processing, comes from : Contact with micro- and nanoplastics in the environment and leaching from contaminated soil and water during planting, irrigation, and growth. Exposure to plastics during harvest […]
Chemical Touted In BPA-Free Products May Cause Heart Problem
Many “BPA-free” products have substituted an almost identical chemical to BPA that has its own health-causing effects. The substitute, bisphenol S (BPS) has the basic chemical structure as bisphenol A (BPA). Evidence is mounting that the use of BPS is a “bait and switch” scheme designed for promoting products instead of health. As a result, […]
