According to U.S. Department of Public Health and Human Services, the adverse health effects from nickel are highly dependent on the degree of exposure. Many health experts are now recommending to use stainless steel cookware low in nickel content. Because of this, we decided to use stainless steel #201 (typically called 18/0) and not stainless steel #304 (typically called 18/8) when is comes to our water bottles in order to have the lowest nickel content possible and still have food grade.
