Edward Hoagland writes the obvious point that "fresh meat will help combat scurvy."

Notes from the Century Before: A Journal from British Columbia by Edward Hoagland
"Steele's grandfather, having shipped around Cape Horn from Ontario in the 1890's, was prospecting with seven other men on Scurvy Creek, as it was named afterwards, which feeds into the Hyland. They'd been eating salt pork for months (even fresh meat will help combat scurvy), and they were all down and dying of the disease when some Indiians happened by and brewed up a pot of juniper tea. Five of the party refused to drink, saying it was Inidian medicine, but Grandfather Hyland and two of his friends drank it and lived. On their stubmilng, hallucinatory trip out, he picked up a chunk of gold ore which prospectors have been searching the river to match ever since." page 93 Hardcover

I actually found this book in the Canadian History section of the Strand bookstore in Manhattan New York City and decided to buy it after finding it mentioning using fresh meat to cure scurvy. I can't even find an index so I think I stumbled upon it while browsing through a couple of pages. Lucky find!
