PROLONGED MEAT DIETS WITH A STUDY OF KIDNEY FUNCTION AND KETOSIS.

BY WALTER S. MCCLELLAN AND EUGENE F. Du BOIS.
It's the 1 year study on Vilhjalmur Stefansson and K. Andersen at Bellevue Hospital.
Vilhjalmur Stefansson
See http://www.jbc.org/content/87/3/651.full.pdf The reason why I'm posting this is because of what Stefansson and Andersen drank. I was under the impression that the men drank water only. That was not the case. They drank coffee, black tea, meat broths and water. Black tea is high in tannins, which bind somewhat to haem iron and very strongly to non-haem iron.

Therefore, if you like to eat lots of red meat but you don't like your greens (not even a tablespoonful of spinach), drink strong black tea or eat foods rich in phytates and/or calcium. Vitamin E supplements also help. See Red meat and colon cancer: should we become vegetarians, or can we make meat safer?

Thank you Charles.

The traditional "All Meat" diet of the Eskimos contained a significant amount of processed carbohydrates.

Are you talking about chlorophyll and tannins to bind to iron to reduce gut absorption in general or to reduce colonic cancer as per the earlier rat study?

Nigel Kinbrum said...

That's a good point. I don't know off the top of my head whether the binding of iron by tannins etc prevents damage to the gut as well as reducing absorption. My, uh, gut feeling is that binding haem iron would render it harmless, but I need to find some evidence.

Even today, coffee provides most of the polyphenols in the diets of many people.

Even instant?

The one thing that has worried me about paleo - red meat, not much veg - is the effect on the kidneys.


Can't see a "kidney" tag on this post, so no idea what you've written before. Linkeys please?

The limit to protein intake is in the liver, not the kidneys. Excessive energy intake from protein results in hyperammoniaemia (a.k.a. Rabbit Starvation). On a maintaining or cutting diet, this is virtually impossible.
