Discussion Overview

The discussion centers around the survival challenges faced by individuals lost at sea for an extended period, specifically addressing the implications of scurvy and the role of vitamin C in survival. Participants explore the physiological effects of hunger and dehydration, as well as the nutritional aspects of surviving on limited resources.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants assert that while people can survive without food for a time, they cannot survive without water, and scurvy will develop without vitamin C over the long term.
  • Others point out that there is mostly anecdotal evidence regarding deaths from scurvy in individuals adrift at sea, noting that thermal issues and exposure are significant factors affecting survival.
  • One participant references the "inuit paradox," suggesting that individuals lost at sea might consume raw fish, which could mitigate the risk of scurvy and water issues.
  • Concerns are raised about the effects of megadoses of micronutrients, such as vitamin C, on the absorption of other essential nutrients, challenging the views of Linus Pauling on vitamin C requirements.

Areas of Agreement / Disagreement

Participants express differing views on the timeline and conditions under which scurvy develops, as well as the role of diet in survival at sea. There is no consensus on the implications of vitamin C and its necessity in extreme survival situations.

Contextual Notes

Participants note limitations in the discussion, including the dependence on anecdotal evidence and the need for more technical understanding of vitamin C's role in human health, particularly in extreme conditions.

Was it that they were lost at sea for 91 days? Did they have lemons? From what I understand, (1) people do not die of hunger, but (2) they will die without water, even though (3) they cannot survive on water alone in the long run because, (4) at the very least, scurvy will kick in. I think according to Linus Pauling, one of the secrets between vitamin C and water is that unlike water, vitamin C underlies survival in the long run. Is this true?

Two points -
1. There is mostly anecdotal evidence for deaths from scurvy in people adrift at sea:
Thermal issues are a big problem -- heat loss burns up calories in cold climates.
Salt water ulcers and exposure are also a problem. Death from scurvy varies from a month to six weeks

2. Vitamin C 101 - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4959991/ - this is technical, which is the way a decent answer to your question should be.

Also megadoses of micronutrients severely alter uptake of other micronutrients:
Example: excess vitamin C prevents copper absorption. So Linus Pauling is not exemplar for Vitamin C requirements.

Well, actually - not necessarily.
Google up 'inuit paradox' (the part about missing plant food and C vitamin*).

If you lost on sea, you likely won't have fire to cook. Raw fish will be more or less the only food you'll have access to. And that may also mitigate the water issue to some extent.

If you lost on sea (and survived for a few weeks already) then scurvy just won't bother you :wink:

(*) ... just noticed that the 'inuit paradox' has other meanings :doh:

And the answer is:
(with a puzzled look) "To get more followers, of course." :))
