Changing Diet .... What Happened?

in 1983, among the same okinawan brazilian, 36% of "healthy adults" were at risk of cardiac infarct.

then prfessor moriguchi instructed dietary change to those people.
less meat, sugar, salt, and more vegetables and fish.
5 years later, even though those people were 5 years older, the rate dropped to 22%!

those 2 studies concluded ;

1 the disease is less genetic, but more "life style", especially diet.
2 japanese diet seems to be ideal to prevent diseases, and for healthier, longer life.
also warned that this was a wake up call for future generation of japanese people, whose diet are rapidly shifting to "western/american style".
