I can;t get this link to work. I also tried typing it in. In fact I am having
a lot of problems with links on this board. Don't know why. I'm missing a lot.

If you are interested in this try thes links

I would agree. What nutritionalists know about food,its compounds and the
aminotransferases are minimal.  So i would not be surprised if the body could
make it. A line from the last link goes "Excess diet aminoacids are neither
stored nor excreted as such: they are converted in pyruvate, oxaloacetate,
a-ketoglutarate, etc. Therefore, aminoacids are also precursors of glucose,
fatty acids, and ketone bodies, and can be used for energy production". And
from the other reading a-ketoglutarate scavenges ammonia. I have to admit a
lot of this is way over my head, but I find it very interesting.

YEs I have noticed this and fair much better on a high fish diet, at least
twice a day (and as they are wee fish - herring, whiting, haddock, I don't
worry too much about mercury, more about the radioactive pollution from
Dounray and Sellafield which is now showing up in Scottish farmed salmon - who
would touch that anyway).

The old wives knew a lot more than we do today.
