Braised, range-fed bison is far richer than feedlot beef in many key nutrients. Bison have interesting odd- chain fatty acids, and reportedly don't get cancer. It is possible that these odd-numbered fatty acids subtly alter fat metabolism in ways beneficial to the monoxygenase receptor for vitaletheine, either directly through the known interaction of this enzyme with fatty acids, or in preventing the breakdown of PUFAs to malondialdehyde, which is known to destroy the monooxygenase. Alpha-linolenic acid, and the fish oils, EPA and DHA, are far higher in bison, and the omega-3 ratio to omega-6 fatty acids is far better than feedlot beef. Evening primrose oil is a better source of the GLA deficient in elderly and diabetics. Phosphatidylserine (bison brain) enhances the monooxygenase & prevents spurious oxidations..
