Episode notes
Lead Risk Hinges On Which Safety Limit You Use
- Consumer Reports found lead in many protein powders, but the alarm depends on the safety threshold used.
- Using extremely conservative Prop 65 limits makes normal foods (apples, tomatoes) appear dangerously high.
Context Matters: Background Lead In Foods
- Background dietary lead exposure matters: many common fruits and vegetables contain micrograms of lead per serving.
- Risk assessment should consider overall exposures and health-based standards, not presence alone.
Prefer Whey And Check Brands If Worried About Lead
- If you can, prefer whey protein over some plant-based powders because whey tended to have lower lead in the tests.
- Check brand sourcing and avoid specific offenders (e.g., certain plant-based products) if you rely on daily powders.
