The Short Version
This claim is not supported by the evidence. The peer-reviewed studies cited actually tested cookware with acidic foods or extreme scenarios like lemon juice stored for five days—not typical water bottle use with neutral water. Under normal conditions, food-grade stainless steel bottles release only trace metals well below established safety thresholds. Claims about lead contamination reference specific defective components, not stainless steel itself. The blanket assertion that these bottles leach metals at harmful levels is a significant overgeneralization.
