To all who responded to and "criticised" my post on nutrition and evolution
of the brain and nervous system:
There are too many to respond to directly; I don't have the time to do so
and my response would take up too many pages for thise venue. My suggestion
is that you read NUTRITION AND EVOLUTION (Keats 1995) by Crawford and Marsh,
which should answer all of your questions and dispel the myths and
misunderstandings many hold about what drives/enables evolution and
development of organs and body size, and also provides a very convincing
argument and evidence that mankind did not evolve on the savanna, but in
coastal ecosystems. It also goes into detail showing how as a matter of
fact the nervous systems and behavioral capacities of carnivores are
advanced over herbivores. I also suggest that you read NUTRITION AND
PHYSICAL DEGENERATION (PPNF 1938, 1975) by Weston Price, which presents
abundant evidence showing how nutrition affects genetic expression and
development of the skull and brain, and probably behavioral capacities, in
humans. A related article is Broadhurst et al (1998) Rift valley lake fish
and shellfish provided brain-specific nutrition for early Homo, Brit J of
Nutr 79:3-21.
BTW, it is not true that the only sources of DHA are brains and marrow.
This fat is found in abundance in ocean fish and fat of sea mammals; eye
balls; egg yolks (especially of water birds); and even some in 'regular'
animal fats (especially from grass fed animals). Marine animals are the
best sources.
