Eucharistic Miracles

A companion post to the Shroud of Turin post.

Sometimes, there just isn't any adequate explanation for something.  Read this and compare to the post linked above.  How does human flesh and blood preserve itself for centuries without any assistance nor help of any kind?  Can anybody make this stuff up?  How do you account for this?

A rigorous scientific analysis was performed in 1970-71 by Professor Dr. Odorardo, University Professor in anatomy and pathological histology and in chemistry and clinical microscopy, Head Physician of the United Hospitals of Arezzo. Prof. Linoli was assisted by Prof. Dr. Ruggero Bertelli, a Professor Emeritus of anatomy at the University of Siena.
  The research done on the fragments of the Blood and the Flesh yielded the following results:

• The Blood of the Eucharistic Miracle is real blood and the Flesh is real flesh.
• The Flesh consists of the muscular tissue of the myocardium (heart wall).
• The Blood and the Flesh belong to the human species.
• The blood type is identical in the Blood and in the Flesh, type AB.
• The proteins in the blood are in the same proportions as those found in normal fresh blood.
• There is no trace whatsoever of any materials or agents used for preservation of flesh or blood.

emphasis added.

Mind you, this was a scientific inquiry. You can challenge this, I suppose. But I wonder if such challenge would make any difference. It is not as if this was a new phenomenon.
