In the book "Nourishing Traditions" it states "Investigation into the effects of pork consumption on blood chemistry has revealed serious changes for several hours after pork is consumed. The pork used was organic, free of trichinosis, so the changes that occurred in the blood were due to some other factor, possibly a protein unique to pork. In the laboratory , pork is one of the best mediums for feeding the growth of cancer cells. The prohibitions against pork found in the Bible and the Koran thus may derive from something other than a concern for parasite contamination. However, in fairness it must be noted that many groups noted for longevity, such as the inhabitants of Soviet Georgia and Okinawa, consume pork meat and lard in their diet on a daily basis. Lard is an excellent source of vitamin D." pg 32
I was also reminded, when reading Molly Bloom's post, that lobster is called the "cockroach of the sea” for its indiscriminate scavenging.
