E-E-A-T Methodology
How the protocol is ranked.
Zero Plastic Protocol is organized by controllability, exposure frequency, plausible particle load, and practicality. It is not a medical protocol. It is a structured behavior and product-substitution framework.
Exposure frequency
Daily, high-volume routes such as drinking water and hot beverages are prioritized because small changes can compound quickly.
Material stress
Heat, abrasion, reuse, and dishwasher cycles are treated as risk multipliers for plastic-contact items.
Low-regret swaps
The protocol favors substitutions that are practical, durable, and useful even as the science evolves.
Evidence caution
The site avoids medical certainty claims and distinguishes exposure-reduction logic from clinical outcomes.
Source hierarchy
Official agencies, standards bodies, peer-reviewed literature, and primary documents are preferred over brand claims or social-media summaries.
Update posture
Pages should be revised when public agencies materially change guidance, measurement methods improve, or a recommendation becomes less practical.
