So what Aajonus said about this is freezing, like cooking, destroys nutrients. The colder foods get, the more nutrients are destroyed. Therefore it is always healthier to eat foods that have never been frozen. The nutrients in meat are especially harmed by freezing. The protein in raw meat that has been frozen is only 25% utilizable in the human body, whereas in fresh raw meat, the protein is nearly 100% utilizable. Freezing meat causes the Escherichia coli bacterium (E. coli) in meat to flourish quickly. When only frozen meat was fed to carnivores, they developed mange and other skin disorders, and sometimes scurvy. When the same meat unfrozen was fed to carnivores, they remained healthy and happy.
