How does Kashrut illustrate a layered determination of fitness?

Answer

Fitness criteria move beyond general health mandates to specific community parameters

The Jewish dietary laws, Kashrut, demonstrate that fitness for consumption is not always a universal standard based only on public health mandates concerning spoilage or contamination. Under Kashrut, certain foods are inherently unfit for observance based on established religious rules, such as mixing meat and dairy or consuming non-kosher animals. This means that even if food passes all general safety checks—making it technically fit for general human consumption—it can still be rejected by a specific community because it violates their layered, community-defined parameters of suitability.
