G'day G'day Alan
It is an important bit of research even if it does leave important
factors untested. I found it annoying that they kept referring back
to alcohol consumption when beer and spirits didn't work. There was
obviously something about wine consumption other than alcohol.
The positive correlation with alcohol there is likely only a marker
for consumption.
For instance it would have been relatively easy to test the
significance of polyphenols by comparing those who preferred red to
white wines.
Thanks for presenting the research. I'm left wondering if it is
important to have the wine with a fish meal. It might not be.
Traditionally people drink white wines with fish.
Best wishes,
Quentin.

"A glass or two of wine per day may increase the amount of
heart-healthy omega-3 fatty acids in a person's blood, a new
study suggests.
The study of European adults found that those who drank in
moderation tended to have higher blood levels of omega-3 ?
even when intake of fish, the major dietary source of the
fats, was taken into account.
The link was strongest among wine drinkers, compared with
those who favored beer and spirits. The findings suggest
that wine, in particular, may affect the body's metabolism
of omega-3 fats, according to the researchers, led by Dr.
Romina di Giuseppe of Catholic University in Campobasso,
Italy."
I found the abstract here:
http://www.ajcn.org/cgi/content/abstract/ajcn.2008.26661v1
"Results: In fully adjusted multivariate analyses, alcohol
intake was positively associated with plasma
eicosapentaenoic acid (EPA), docosahexanoic acid (DHA), and
EPA + DHA concentrations (P < 0.0001, P = 0.036, and P =
0.002, respectively) in women and with EPA and the EPA + DHA
index in red blood cells (P < 0.0001 and P = 0.037,
respectively). In men, only plasma and red blood cell EPA
concentrations were associated with alcohol intake (P =
0.003 and P = 0.004, respectively). Stratified analyses
showed an association between alcohol and both plasma and
red cell EPA (P = 0.008 and P = 0.002, respectively), DHA (P
= 0.014 and P = 0.008, respectively), and the EPA + DHA
index (P = 0.010 and P = 0.006, respectively) in wine
drinkers, whereas no association was found in those who
drink beer and spirits.
Conclusions: Alcohol intake was associated with higher
plasma and red blood cell concentrations of marine n?3 FAs.
Components of wine other than alcohol (polyphenols) might
exert these effects. Part of the alcohol-induced
cardioprotection may be mediated through increased marine
n?3 FAs."
