An anonymous reader quotes a report from ScienceDaily:The researchers note that humans are repeatedly exposed to Neu5Gc when they consume red meat, as it prompts an immune response and chronic inflammation they call "xenosialitis." "In their tests, human-like mice modified to lack the CMAH gene were fed a Neu5Gc-rich, high-fat diet and subsequently suffered a further 2.4-fold increase in atherosclerosis, which could not be explained by changes in blood fats or sugars," reports ScienceDaily.The study has been published in the journal PNAS
