... wine and comment on the rich full body with complex overtones of lavender and a hint of cinnamon.  To me it all tastes like spoiled grape juice and is scarcely distinguishable from cheap vinegar.

Yes, the sweetness of water on a high animal-fat diet due to some ketone spillage into the saliva, and presumably knowledge passed down the generations to avoid illness, are so far the explanations I can think of for the high consumption of water by Inuit. There may be other reasons as well. It's total speculation on my part, but I'm guessing that eating enough fat to produce a small amount of ketones so that water is slightly sweet may be an optimal level for someone on a VLC, ZC or carnivore diet, so as to encourage the right amount of water consumption. This could be a temporary effect, though, as over time it takes increasing amounts of fat to produce a very slightly sweet taste in my saliva and water, whereas early on less fat produced a very strong sweet taste.

I mean I get to believe the whole time that this is not healthy - not a balanced diet; no fiber (my Dad).

I recently began to have a nasty sweet aftertaste in the back of the mouth after drinking my organic Colombian coffee, also from the Maubesse (Timor). Tried a (proven safe) commercial coffee, there's less of that taste.

I like the idea that the taste is caused by ketone bodies, but have no idea why coffee should do this, or what it means.
