Does anyone know the the vitamin c content of boiled vegetable water? All the studies I find are focusing on the content of the vegetables post-boil, as opposed to the content in the boiled water.

My interpretation of what I could find is that vitamin C breaks down in water pretty fast.

Staring at orange juice in confusion...

Googling to try to fix confusion...

Looks like the rate of decay depends very highly on temperature and pH? So in cool acid in a citrus fruit, it's fine; in warm (or boiling!) neutral water in a veggie pot, it's gone?

Decay seems to depend on everything, heat, pH, sunlight, oxygen, etc. Seems almost amazing that vitamin C exists at all.

arctic explorers kept getting scurvy, and the traditional citrus and so on didn't help as they pre-squeezed the juice before embarkment to preserve it, destroying the vitamin C over the next few weeks. So they concluded the whole 'citrus cures scurvy' thing was an old wives' tale and the disease must be due to some contamination of their food supplies, so they scrubbed and sanitized everything to no effect.

Fresh seal/dolphin/whale skin has some C in in though, so when they finally hunted fresh meat in desperation and the scurvy went away, they concluded it must just be a really damn stubborn contamination in their meat supply making them sick. Interesting example of a clearly-effective discovery being 'undiscovered.'

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
