I am apparently still an Atkins pedant, because I have to point out that it is relatively high-fat.

I've not heard of "rabbit starvation" - does it mess with your gall bladder?

Unsafe levels of protein. It has been observed that human liver cannot metabolise much more than 200-300 g of protein per day, and human kidneys are similarly limited in their capability to remove urea (a byproduct of protein catabolism) from the bloodstream. Exceeding that amount results in excess levels of amino acids, ammonia (hyperammonemia), and/or urea in the bloodstream, with potentially fatal consequences,[1] especially if the person switches to a high-protein diet without giving time for the levels of his hepatic enzymes to upregulate.

Noted! Humans can live on an all-meat diet as long as the meat is fatty.

Well, they bring the already baked biscuit on ship, don't they?

They did. It lasted so long that WWI soldiers got biscuit stamped with "Remember the Maine" on it.

Also, Water Crackers are basically the same thing but not quadruply baked, and much thinner. Also Carr's charges way too much for them. Or at least I find their profit margin excessive, since you can get them from TJ's for ninety-nine cents.

It also has a lot of vegetables! Sheesh.

And, as the first episode of "Due South" reminded us, there's pemmican (meat, fat and, I believe, berries). um, yum?

Good one, Todd. Pemmican is definitely travel food in narratives set in the frontier.

I always wanted to try some. Yeah, it involved berries.

One of the key foods for sailors in the Age of Sail was salted meat: it's one of the reasons the Portuguese became so powerful, because they cornered the cod fisheries in the North Atlantic, and cod salts up really well.

The enormous reliance on salt cod and salt pork and whatever gave rise to scurvy, hence the use of limes, and hence the term "limey" to refer to a British sailor.

For reasons that I have yet to figure, we always had pilot bread (hardtack) in the house as a kid.

So I'd eat it while pretending to be on a ship, or otherwise adventuring.

Pemmican is actually pretty tasty, IMHO. I mean, I wouldn't want to live off of it, but I would snack on it now and again as a kid.

Yeah, it's big in Canada (esp. Newfoundland) and Alaska. Apparently you need it for some Canadian meal called "fish and brewis" which also requires something called "scrunchions."

Scrunchions - is that what they make scrunchies out of?
