I do not know what new data was learned since then but he had a great post on one or more of the preservatives showing that in studies (which use extreme amounts) the types of malignancies that were found in increased numbers were types common to some rodents and humans but often ***not*** common for members of Carnivora. Also, I remember his writing that with at least one of those preservatives at least one type of malignancy was at a lower rate in the animals who got the preservative than in the animals not fed the preservatives, and that (those?) type (s) is/are more often found in ferrets than in rodents or humans. If I recall right he also said that he figured that the changes in rates both up and down are often misleading and inaccurate. His point that I remember was that many non-expert references are by people who use pseudoscience, do not understand the studies, or do not realize that results often can not be generalized among widely divergent types of animals. And I hope that I stated my request clearly enough because I had about 2 hours of sleep. 8 months after we found out that Mornie's carcinoma could cause her Cava to give out it finally did so we lost her this morning. Oh, and this is good website: http://www.petdiets.com/ If my memory serves the primary person in it is a woman who has BOTH a veterinary medicine doctorate and a veterinary nutrition doctorate focusing on members of Carnivora. Anyway, does anyone have that post. I could not spot it in the archives so fear it may precede the archives.

If you know otherwise I'll be glad to search the other years that aren't yet online. BIG] [Posted in FML 6842]
