I was reviewing this document by Spitze et al published in 2003 (UC Davis). http://www.vetmed.ucdavis.edu/vmb/labs/aal/pdfs/spitze.pdf
Taurine concentrations in animal feed ingredients; cooking influences taurine content J. Anim. Physiol. a. Anim. Nutr. 87 (2003), 251–262
According to this document, chicken liver has far, far more taurine than heart:
Chicken, heart and liver 1179 (888 - 1561) mg taurine/kg wet weight / 5132 (4315 - 6441) mg taurine/kg dry weight
Chicken, liver 1100mg as fed, 4668 DMB.
Chicken heart contains 79mg taurine/kg as fed? Really? And 464mg DMB vs chicken liver at 4668mg DMB? Does this even make sense?
Chicken dark meat: 1690mg taurine/kg as fed / DMB not available.
????????
For beef, heart is listed as 652mg as fed and 3461mg DMB vs liver at 688mg as fed and 2359 DMB.
Compare that to lung (956mg as fed / 3938 DMB), spleen (874mg as fed / 5848 DMB), and Tongue (1110mg as fed / 4158 DMB)
What am I missing?
Just the information that beef heart is taurine rich - chicken heart isn't - and organs have more than heart? :dk:
Is it just a myth that "heart" is taurine-rich and it is type-of-protein dependent? Sadly, only info for beef heart and (implied) chicken heart is included in the report.
Is the chicken heart info just wrong?
And the usual "taurine is concentrated in electrically active muscles" seems to hold true, though I guess secreting organs are very electrically active? :dk: Lungs and tongues certainly are....
Can anyone help me make sense of commonly repeated information vs this data?
Thank you!
