I'm not entirely sure yet which amino acids are responsible for the beef-related insulin spikes.

Leucine is an amino acid that has been shown to spike insulin, but I eat bison and bison has roughly the same amount as beef.

I plan to research this as a biochemist down the line. Hopefully I can figure out why.

All I know at this point is that I can't tolerate beef at all. It's as if I were eating sugar.
