Omega 3. is it only found in fish?!
Answers: im not too happy that its put into kingsmill bread
Actually, omega-3s can be found in several other sources; a popular vegan/vegetarian one is Flaxseeds or Flaxseed Oil.
However, an experienced vegan (or vegetarian) knows: always read the ingredient lists. If you don't know what one of the ingredients is, or if it's vegan-friendly (or vegetarian-friendly), then don't buy it. :)
no not just fish. Omega 3 is actually a certain arrangement of carbon single and double bonds on a fatty acid triglyceride. It is found in greater quantity in fish but can also be found in some vegetable oil just at a lower concentration. Don't know why you are not happy, it's supposed to be good for you.

nope, its found in some nuts, oils, algae, seeds .. like flax seeds.
The best kind for vegetarians though is the omega 3 that comes from the algae because it contains all types of the omega 3. It contains epa , dha, and ala.
Plant sources provide only the Omega 3 fatty acid ALA. We can find ALA in dark green leafy vegetables like Spinach and Broccoli, Walnuts, Canola Oil, Pumpkin Seeds, and Perilla, but the most significant source of ALA is probably Flaxseed oil. According to the Vegetarian Society, 14 gr of Flaxseed Oil will provide 8.0 gr of ALA compared to 1.3 gr for the same amount of Walnuts.
Both EPA and DHA are found in oily fish such as Salmon, Mackerel, Tuna, Herring, Anchovies and Sardines.
More and more products are being produced with added Omega 3 including milk (white or chocolate), eggs, cereals, etc.
lol wow that guy really wanted to answer that question. but no its not only in fish. i actually found omega 3 in tortilla's. there way healthier then the other tortilla's and there good too.
They put fish in bread?
Hm, well, omega 3 is found outside of fish.
Plenty of vegetarian choices if that's what you are hinting at.
flax seed, but must be fresh ground or they begin to break down. Use daily dose in peanut butter, soup or cereals, juice.
At the moment omega 3 seems to be being put into everything! It can only be good for you though x
here is a list of vegan foods high in omega 3's

No..the best source of omega-3 fatty acid is flaxseed oil and flaxseeds. (six times richer than most fish oils). There is also walnuts, canola oil, & tofu.
walnuts DOH
ps: i know man fish oils are in my moms juice 2 and now i cant have none
No, it's also in borage and flaxseed oils, among other things. If you're worried about the bread, make your own. You'll have more control and it isn't so hard. It's also cheaper and nicer.
Nope. Fish get it from eating algae, and so can you. It's also in flaxseed and flaxseed oil, hemp seed and hemp oil, walnuts, and canola, to name a few.
No, it's not found only in fish. Flax seeds and flax oil are a rich source of omega-3 (I don't know about Kingsmill bread, but maybe that's where their omega-3 is coming from?) You an also find it in walnuts. Oh, and we can always get it from the same source as the fish do: marine microalgae.
Just a tablespoon of flax seed will give you all the omega 3 you need. Eating fish will lead to sickness and death.
wow i never knew it was in BREAD!!!
good looking out.
but to answer you question, you can find it in flax seeds.
oh yea, did you know that some pills contain fish oil too! uck how disgusting.

Essential fatty acid
ω?3 fatty acids (commonly spelled omega-3 fatty acids) are a family of polyunsaturated fatty acids which have in common a carbon-carbon double bond in the ω?3 position.
Important nutritionally essential ω?3 fatty acids are: α-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). For a more complete list, see list of ω?3 fatty acids. The human body cannot synthesize ω?3 fatty acids de novo, but it can form 20- and 22-carbon unsaturated ω?3 fatty acids from the eighteen-carbon ω?3 fatty acid, α-linolenic acid. These conversions occur competitively with ω?6 fatty acids, which are essential closely related chemical analogues that are derived from linoleic acid. Both the ω?3 α-linolenic acid and ω?6 linoleic acid are essential nutrients which must be obtained from food. Synthesis of the longer ω?3 fatty acids from linolenic acid within the body is competitively slowed by the ω?6 analogues. Thus accumulation of long-chain ω?3 fatty acids in tissues is more effective when they are obtained directly from food or when competing amounts of ω?6 analogs do not greatly exceed the amounts of ω?3.

[edit] Chemistry
Chemical structure of alpha-linolenic acid (ALA), an essential ω?3 fatty acid, (18:3Δ9c,12c,15c). Although chemists count from the carbonyl carbon (blue numbering), physiologists count from the ω (omega) carbon (red numbering). Note that from the ω end (diagram right), the first double bond appears as the third carbon-carbon bond (line segment), hence the name "ω?3"For detail on ω (omega) nomenclature and numbering, see EFA Nomenclature.
The term ω?3 (aka "n?3", "omega-3") signifies that the first double bond exists as the third carbon-carbon bond from the terminal methyl end (ω) of the carbon chain.
ω?3 fatty acids which are important in human nutrition are: α-linolenic acid (18:3, ALA), eicosapentaenoic acid (20:5, EPA), and docosahexaenoic acid (22:6, DHA). These three polyunsaturates have either 3, 5 or 6 double bonds in a carbon chain of 18, 20 or 22 carbon atoms, respectively. All double bonds are in the cis-configuration, i.e. the two hydrogen atoms are on the same side of the double bond.
[edit] Biological significances
The biological effects of the ω-3 are largely mediated by their interactions with the ω-6 fatty acids; see Essential fatty acid interactions for detail.
A 1992 article by biochemist William E.M. Lands[1] provides an overview of the research into ω?3 fatty acids, and is the basis of this section.
The 'essential' fatty acids were given their name when researchers found that they were essential to normal growth in young children and animals. (Note that the modern definition of 'essential' is more strict.) A small amount of ω?3 in the diet (~1% of total calories) enabled normal growth, and increasing the amount had little to no additional benefit.
Likewise, researchers found that ω?6 fatty acids (such as γ-linolenic acid and arachidonic acid) play a similar role in normal growth. However, they also found that ω?6 was "better" at supporting dermal integrity, renal function, and parturition. These preliminary findings led researchers to concentrate their studies on ω?6, and it was only in recent decades that ω?3 has become of interest.
In 1963 it was discovered that the ω?6 arachidonic acid was converted by the body into pro-inflammatory agents called prostaglandins. By 1979 more of what are now known as eicosanoids were discovered: thromboxanes, prostacyclins and the leukotrienes. The eicosanoids, which have important biological functions, typically have a short active lifetime in the body, starting with synthesis from fatty acids and ending with metabolism by enzymes. However, if the rate of synthesis exceeds the rate of metabolism, the excess eicosanoids may have deleterious effects. Researchers found that ω?3 is also converted into eicosanoids, but at a much slower rate. Eicosanoids made from ω?3 fats often have opposing functions to those made from ω?6 fats (ie, anti-inflammatory rather than inflammatory). If both ω?3 and ω?6 are present, they will "compete" to be transformed, so the ratio of ω?3:ω?6 directly affects the type of eicosanoids that are produced.
This competition was recognized as important when it was found that thromboxane is a factor in the clumping of platelets, which leads to thrombosis. The leukotrienes were similarly found to be important in immune/inflammatory-system response, and therefore relevant to arthritis, lupus, and asthma. These discoveries led to greater interest in finding ways to control the synthesis of ω?6 eicosanoids. The simplest way would be by consuming more ω?3 and fewer ω?6 fatty acids.
[edit] Health benefits
September 8, 2004, the U.S. Food and Drug Administration gave "qualified health claim" status to eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) ω?3 fatty acids, stating that "supportive but not conclusive research shows that consumption of EPA and DHA ω?3 fatty acids may reduce the risk of coronary heart disease."[2] This updated and modified their health risk advice letter of 2001 (see below).
People with certain circulatory problems, such as varicose veins, benefit from fish oil. Fish oil stimulates blood circulation, increases the breakdown of fibrin, a compound involved in clot and scar formation, and it lowers the blood pressure.[3][4] There is strong scientific evidence, that ω?3 fatty acids significantly reduce blood triglyceride levels[5][6][7][8] and regular intake reduces the risk of secondary and primary heart attack.[9][10][11][12]
Some benefits have been reported in such conditions as rheumatoid arthritis[13][14] and cardiac arrhythmias.[15][16][17]
There is a promising preliminary evidence, that ω?3 fatty acids supplementation might be helpful in cases of depression[18][19] and anxiety.[20][21] Studies report highly significant improvement from ω?3 fatty acids supplementation alone and in conjunction with medication.[22]
Some research suggests that fish oil intake reduces the risk of ischemic and thrombotic stroke.[23][24][25] However, very large amounts may actually increase the risk of hemorrhagic stroke (see below). Lower amounts are not related to this risk.[26] 3 grams of total EPA/DHA daily are considered safe with no increased risk of bleeding involved[27] and many studies used substantially higher doses without major side effects (for example: 4.4 grams EPA/2.2 grams DHA in 2003 study).[28]
Several studies report possible cancer prevention effects of ω?3 fatty acids (particularly breast, colon and prostate cancer).[29][30][31] No clear conclusion can be drawn at this time, though.
A 2006 report in the Journal of the American Medical Association concluded that their review of literature covering cohorts from many countries with a wide variety of demographic characteristics demonstrating a link between ω?3 fatty acids and cancer prevention gave mixed results.[32] This is similar to the findings of a review by the British Medical Journal of studies up to February 2002 that failed to find clear effects of long and shorter chain ω?3 fats on total mortality, combined cardiovascular events and cancer.[33]
In 1999, the GISSI-Prevenzione Investigators reported in the Lancet the results of major clinical study in 11 324 patients with a recent myocardial infarction. Treatment with omega-3 fatty acids 1 g/d reduced the occurrence of death, cardiovascular death and sudden cardiac death by 20%, 30% and 45% respectively. [34] These beneficial effects were seen already from three months onwards.[35]
In April 2006, a team led by Lee Hooper at the University of East Anglia in Norwich, UK, published a review of almost 100 separate studies into ω?3 fatty acids, found in abundance in oily fish. It concluded that they do not have a significant protective effect against cardiovascular disease.[36] This meta-analysis was controversial and stands in stark contrast with two different reviews also performed in 2006 by the American Journal of Clinical Nutrition[37] and a second JAMA review[38] that both indicated decreases in total mortality and cardiovascular incidents (i.e. myocardial infarctions) associated with the regular consumption of fish and fish oil supplements. In addition ω?3 has shown to aid in other mental disorders such as aggression and ADHD (Attention Deficit Hyperactive Disorder).[citation needed]
Several studies published in 2007 have been more positive. In the March 2007 edition of the journal Atherosclerosis, 81 Japanese men with unhealthy blood sugar levels were randomly assigned to receive 1800 mg daily of eicosapentaenoic acid (EPA - an ω?3 essential fatty acid from fish oil) with the other half being a control group. The thickness of the carotid arteries and certain measures of blood flow were measured
No, but I once found a fish in my Oldsmobile Omega!
