So how much fatty fish should we be getting while in the hospital? I just recently started buying tins of sardines in mustard sauce and making sandwiches of them.
And;
A Brain Posts blogger writing about it here:
The abstract here; I'm sure your doctor knows nothing of it, its only 4 months old.
Abstract
BACKGROUND:
Consumption
of tuna or other broiled or baked fish, but not fried fish, is
associated with fewer subclinical brain abnormalities on magnetic
resonance imaging (MRI). We investigated the association between plasma
phospholipid omega-3 polyunsaturated fatty acids (PUFAs), objective
biomarkers of exposure, and subclinical brain abnormalities on MRI.
METHODS AND RESULTS:
In
the community-based Cardiovascular Health Study, 3660 participants aged
≥ 65 underwent brain MRI in 1992-1994, and 2313 were rescanned 5 years
later. MRIs were centrally read by neuroradiologists in a standardized,
blinded manner. Participants with recognized transient ischemic attacks
or stroke were excluded. Phospholipid PUFAs were measured in stored
plasma collected in 1992-1993 and related to cross-sectional and
longitudinal MRI findings. After multivariable adjustment, the odds
ratio for having a prevalent subclinical infarct was 0.60 (95% CI, 0.44
to 0.82; P for trend = 0.001) in the highest versus lowest long-chain
omega-3 PUFA quartile. Higher long-chain omega-3 PUFA content was also
associated with better white matter grade, but not with sulcal or
ventricular grades, markers of brain atrophy, or with incident
subclinical infarcts. The phospholipid intermediate-chain omega-3 PUFA
alpha-linolenic acid was associated only with modestly better sulcal and
ventricular grades. However, this finding was not supported in the
analyses with alpha-linolenic acid intake.
CONCLUSIONS:
Among
older adults, higher phospholipid long-chain omega-3 PUFA content was
associated with lower prevalence of subclinical infarcts and better
white matter grade on MRI. Our results support the beneficial effects of
fish consumption, the major source of long-chain omega-3 PUFAs, on
brain health in later life. The role of plant-derived alpha-linolenic
acid in brain health requires further investigation.
