Good article. Thanks for posting it, capsu78.

I would think that a useful ability to have in a survival situation is to be able to stomach just about any kind of food source. Vegans, vegetarians, and folks with numerous food allergies would be, in my opinion, a liability if food variety was scarce. After awhile, vegans and vegetarians can't digest meat without getting really sick.

And from what I learned while reading "Ada Blackjack," fresh, raw meat has loads of vitamin C, and can heal/ward off scurvy. One of the explorers died horribly from scurvy, not starvation, while in the Arctic.
