ERRATA:
 
Oops, I made a mistake in my earlier posting.  Thanks to Shankar
Bhattacharyya for his alert observation of the error, it turns
out that what I listed as being composition for "beef" was only
for "beef FAT".  Permit me to post a corrected table and also add
an entry for raw beef sirloin (boneless, 72% lean).  I would have
preferred an entry for hamburger since tofu is often used for
vegi-burgers, but my British reference doesn't provide a listing
for hamburger (!).
