Eicosapentanoic
Acid (EPA) & Docosahexaenoic Acid (DHA) “Fish Oil Therapy!” A project started by Wildegeest Foundation in 2006 because of our belief that laissez-faire attitudes towards fats and oils, including fish oils, are damaging the American diet, and denying important benefits. There are at least 8000 published papers, over half in professional journals, that describe the benefits of the two most important omega-3 fatty acids in fish oils (EPA and DHA). The evidence keeps building - that our need for EPA and DHA is just as real as our need for Vitamin C, which was denied scurvy-ridden people until the 20th Century. We must not condone scurvy- ad lib-dishing out of EPA/DHA Benefits. Fish Oil Therapy Project (FOTP) - Protocol At the start of the four month trial, each volunteer agreed to take a daily dose of three capsules (3 grams) of a carefully selected Wild Alaskan Sockeye Salmon Oil (total 690 mg. Omega-3 long chain fatty acids incl. 330 mg. EPA and 300 mg/ DHA. www.vitalchoice.com . At the start and end of the four month interval, FOTP volunteers’ blood samples were submitted to OmegaMetrix Laboratory in Kansas City for Omega-3 Index (O3I) determinations. Their reliable assay method was needed to monitor the percentages of EPA+DHA = Omega-3 Index (O3I), measured by analysis of the lipids in red blood cells (RBCs). The percent findings, on a 0 to 12% scale are interpreted as a measure of cardiovascular risk. Dr. Harris has stated that the (O3I) target for everyone should be at least 8%. As an unexpected bonus, OmegaMetrix also provided the fatty acid data that was part of (O3I) determinations :- Total Omega-3 fatty acids - Alpha-linolenic acid - EPA - DPA - DHA - Linoleic Acid - Arachidonic Acid, thereby providing important information concerning Omega-6/Omega-3 and AA/EPA ratios. Nine
participants completed a Dietary Questionnaire. While this limited
sampling could not produce definitive results, there were replies
that indicated how lifestyle and food preferences influence (O3I),
including fish consumption, salad dressings, store-bought baked
goods, and the extent to which the
Twenty participants, under medical supervision, received an

LDL-C, Triglycerides, and other . Observations Suggested by FOTP FOTP has accumulated large amounts of background information, still under review, but certain observations are of immediate interest:: 1.
U. S. Population Deficient in EPA/DHA, Suffers Elevated Omega-6's
2. Will Seafood Twice/Week Satisfy EPA/DHA Requirements?
3.
Should Fish Oils be Added to Manufactured Foods? 4.
Should fish oils be taken without antioxidants? 5.

Oxidative
Stress : Because the
structural integrity of the membrane depends on the bio-physical
properties of the different phospholipid species, the inherent high
ability of n-3 fatty acids to oxidize may eventually prevent
hemolysis by trapping most of the free radicals and reducing the
variety of oxidized Polyunsaturated Fats, Safe or Not Safe : The most common PUFA’s are linoleic acid, linolenic acid, EPA and DHA. Linoleic acid has the (n-6) and the others have the (n-3) configuration. Thinks there is safety in <10% caloric intake, but beyond that cautions antioxidants . Some evidence n-6 PUFA’s involved in initiating cancer. Eritsland, J. Safety considerations of polyunsaturated fatty acids. Amer.J. Clin.Nut, Vol. 71 (suppl) Jan.2000. Prudent Diet re: Eat Fish Regularly : Authors conclude, even though food tables may show that some lean fish do contain EPA and DHA, for some reason these fish do not increase serum levels of EPA and DHA. Advice needs revision, to apply only to salt water fish (especially salmon, mackerel, sardines, herring). Philbert, et al, Fish intake and serum fatty acid profiles from freshwater fish. J. Clin. Nut.Vol.84, Dec. 2006, pp.1299.
Prudent
Diet re: Other fats Interference :
Researchers report that conversion
of ALA to DHA in vegans is negligible and similar results applied to
meat eaters. Concluded, ALA not effective in increasing DHA levels.

term supplementation of low-dose gamma-linolenic acid (GLA), alpha
linolenic acid (ALA), or GLA+ALA does not augment LCP omega-3
status of Dutch vegans Prudent Diet re: Fish Oils Vital to Health : Research over twenty years have shown EPA and DHA are essential elements in humsn nutrition. DHA is a vital component of the phospholipids in cell membranes throughout the body, particularly abundant in the brain, retina, and sperm. Fish oil supplementation significantly lowers overall triglyceride and cholesterol levels without affecting the level of HDL (“good cholesterol). Connor, J.

U.
S. Need for DHA :
Inadequate intake of DHA by most Americans , the building block of
human brain tissue and the retina. Low levels have been associated
with depression, memory loss, dementia, visual problems. DHA
important to fetuses, infants; The DHA content of the infant’s brain
triples during the first three months ; the average DHA content of
breast milk in the U. S. Is the lowest in the world - most likely
because Americans eat so little fish. Levine, B, Most
