One simple sugar found in mammalian meat, but not natural in humans, is now possibly liked to cancer. Neu5Gc, the sugar at the center of this study, when eaten by mice who also lack the sugar naturally were found to have a significant increase in spontaneous cancers. Furthermore the sugar is highly bio available, or free to move about the bloodstream, and into tissues. The human immune system does not recognize the foreign Neu5Gc molecule and makes antibodies to protect the tissues causing inflammation, a leading cause on cancer in the body.  

Does this mean red meat is completely out? No, read meat can still be a good addition to your diet nutritionally but scientists will now look closer at the connection between red meat consumption and chronic inflammation the can lead to tumors, atherosclerosis, and type 2 diabetes.
