On: Making chicken transparent using Dorito dust

[phs318u]

I understand how the kosher rules around food probably originated - basically avoiding what in those times would have been dangerous options. Do the kosher rules get updated for the modern era with respect to things like additives etc? We’ve learned that many modern additives (can) have negative health impacts. Do things like this get considered?

No because the laws were specific not general. But obviously people can follow the inspiration of avoiding "unclean" food.
