Quoted message said:Exposure to heat, light, temperature, pressure, etc. are

most destructive. The destruction of long-chain omega3s in
fish, or any other substance containing omega3s, for that

cooking and works its way inward towards the center with
increasing time, temperature, and/or pressure.

You're misstating the claims of the studies you erroneously
cited. Frying isn't "destructive," it is counterproductive:
it contributes *other* lipids to those found in the fish.
It's especially self-defeating if one fries one's salmon in
shortening or another transfat as Dr Kris-Etherton notes in
another study of fish oils and cardiac health: "Commercially
prepared fried fish (eg, from restaurants and fast food
establishments, as well as many frozen, convenience-type
fried fish products) should be avoided because they are low
in omega-3 and high in trans-fatty acids."

Dr Kris-Etherton, et al, concluded: Collectively, these data
are supportive of the recommendation made by the AHA Dietary
Guidelines to include at least two servings of fish per week
(particularly fatty fish). In addition, the data support
inclusion of vegetable oils (eg, soybean, canola, walnut,
flaxseed) and food sources (eg, walnuts, flaxseeds) high in
-linolenic acid in a healthy diet for the general population
(Table 5). The fish recommendation must be balanced with
concerns about environmental pollutants, in particular PCB
and methylmercury, described in state and federal
advisories. Consumption of a variety of fish is recommended
to minimize any potentially adverse effects due to
environmental pollutants and, at the same time, achieve
desired CVD health outcomes. Op. cit.

practical implications. Am J Clin Nutr 2003; 78 (Suppl):

The abstract of the above cited study says: Although
vegetarian diets are generally lower in total fat, saturated
fat, and cholesterol than are nonvegetarian diets, they
provide comparable levels of essential fatty acids.
Vegetarian, especially vegan, diets are relatively low in
alpha-linolenic acid (ALA) compared with linoleic acid (LA)
and provide little, if any, eicosapentaenoic acid (EPA) and
docosahexaenoic acid (DHA). Clinical studies suggest that
tissue levels of long-chain n-3 fatty acids are depressed in
vegetarians, particularly in vegans. n-3 Fatty acids have
numerous physiologic benefits, including potent
cardioprotective effects. These effects have been
demonstrated for ALA as well as EPA and DHA, although the
response is generally less for ALA than for EPA and DHA.
Conversion of ALA by the body to the more active longer-
chain metabolites is inefficient: < 5-10% for EPA and 2-5%
for DHA. Thus, total n-3 requirements may be higher for
vegetarians than for nonvegetarians, as vegetarians must
rely on conversion of ALA to EPA and DHA. Because of the
beneficial effects of n-3 fatty acids, it is recommended
that vegetarians make dietary changes to optimize n-3 fatty
acid status. snipurl.com722aOpen ↗
It says ABSOLUTELY NOTHING about conversion of essential
fatty acids into transfats through cooking.

Circulation 2003; 107: 1372-1377
that study says: It may seem like common sense, but the
species of fish you eat and the way it is prepared makes a
difference to its health-protecting properties. It is widely
accepted that the benefits associated with fish consumption
relate largely to their long-chain omega-3 polyunsaturated
fatty acids (n-3 LC-PUFAs), which are found in few other
foods. Few studies, however, have described or analyzed
their findings according the type of fish consumed. In
particular, U.S. studies, where the consumption of fish is
low, seldom have the ability to make this type of
distinction. But Mozaffarian and coworkers have shown that
fish is not simply "fish."
They compared the effects on cardiac mortality of
eating tuna, fried fish or fish sandwiches, and other
broiled or baked fish species in adults aged 65 or
older, who were free of CVD at baseline. Subjects were
monitored for 9.3 years. Because they were related, the
consumption of tuna and "other fish" was combined.
Eating tuna or other broiled/baked fish reduced the
risk of cardiac death, particularly those from cardiac
arrhythmia, by nearly half compared with the fried fish
eaters. Those who ate tuna or other fish three
times/week or more had a 49% lower chance of fatal
heart disease and a 58% reduced likelihood of fatal
cardiac arrhythmia compared with those eating tuna or
other fish less than once/month. Eating fried fish or
fish sandwiches not only failed to guard against
cardiac fatality, it tended to make it more likely.
Several differences between the two types of fish
consumption can be suggested. Fried fish and
commercially prepared fish sandwiches are *HIGH IN FAT
BECAUE OF THE FAT ADDED DURING PREPARATION AND
COOKING*. Fish sandwiches are usually made with lean
white fish, the kind with the *LEAST N-3 LC-PUFAs*. In
addition, the KIND OF FAT ADDED is likely to contain
SATURATED and partially hydrogenated fat with TRANS
FATty acids. Neither of these help the heart. So,
choose fatty fish species for the most n-3 LC-PUFAs and
prepare them with as little additional fat of any kind.

My emphasis in the above. There is not *one word* of warning
about conversion into trans fat, but rather that trans fats
used to cook lean white fish which is already low in
beneficial oils doesn't contribute to heart health (quite
the opposite. Just as the summary starts, it's COMMON SENSE.
Too bad you have none of that and instead misinform others
either intentionally or through your own incompetence.
