The traditional Japanese diet based on rice, fish and vegetables nourishes and protects,

intolerance.) Genetics? Try a genetic intolerance for glutens (and junk food
Why complicate things beyond the obvious?

"Genetic and Infectious profiles of Japanese MS patients"
Background Nationwide surveys conducted
in Japan over the past thirty years have revealed a four-fold increase in the
estimated number of multiple sclerosis (MS) patients, a decrease in the age
at onset, and successive increases in patients with conventional MS, which
shows an involvement of multiple sites in the central nervous system,
including the cerebrum and cerebellum. We aimed to clarify whether genetic
and infectious backgrounds correlate to distinct disease phenotypes of MS in
Japanese patients.... Read More - http://www.msrc.co.uk/index.cfm/fuseact ...
