A Summary of Dr. Kaayla Daniel's New Report on Green Pasture's Fermented Cod Liver Oil and Butter Oil
by Ron Schmid, ND
Kaayla T. Daniel PhD, author of The Whole Soy Story: The Dark Side of America’s Favorite Health Food,
Vice President of the Weston A. Price Foundation, and 2005 winner of
the Foundation’s Integrity in Science award, has just published an
Hook, Line and Stinker! The Truth About Fermented Cod Liver Oil.
We carried Green Pasture FCLO and Butter Oil for many years until I
read Dr. Daniel’s report. I have prepared this summary of her report so
that our customers may learn why we no longer carry these products.

Summary of Dr. Daniel’s Report:
Green Pasture brand “fermented cod liver oil” (FCLO) has been promoted
by the producer and the Weston A. Price Foundation as the only true
“traditional” cod liver oil and the “high vitamin” cod liver oil
recommended by Dr. Weston Price. Dr. Daniel had concerns about many of
the claims and brought them to the attention of Sally Fallon Morell,
President of the Foundation, and requested testing. Morell and the Board
declined. Dr. Daniel on her own had extensive testing done at world
renowned marine lipid laboratories. The following are some of her
- Flavors, odors and colors are
indicative of rancidity – extreme rancidity – and that’s what the data
show. Several lab managers said FCLO was the most rancid oil they’d
ever tested. A massive body of research shows rancid polyunsaturated
fatty acids can contribute to heart disease, cancer and other ills.
- Levels of fat-soluble vitamins
reported by the labs utilized for this testing are significantly lower
than those reported on the Weston Price Foundation and Green Pasture
web sites. Levels of vitamin D are strikingly low, in contrast with the
high levels reported by Green Pasture, which has reported especially
high levels of vitamin D2. The world’s leading vitamin D researcher
states that he has never found vitamin D2 in cod liver oil.
Interestingly, a number of doctors and other health care professionals
have reported severe vitamin D deficiencies among some patients who
have been taking daily doses of FCLO for months or even years.
- Green Pasture claims stupendous
amounts of vitamin K and significant amounts of Coenzyme Q10 in FCLO.
The world’s leading vitamin K research center found extremely low
levels of vitamin K; another lab showed nearly undetectable levels of
- The ratio of EPA to DHA for Arctic
cod should be about 6 to 10. Testing at the two labs sent samples of
FCLO to show the ratio of EPA to DHA to be approximately 2 to 1. These
numbers do not match Arctic cod, and in fact are similar to what one
would expect from Alaskan pollock.
- According to the Green Pasture
website, the “cod livers” in the Green Pasture Cattle Lick product are
left over from the manufacture of FCLO. Dr. Daniel had DNA testing done
on the product. The lab reports that the liver is “100 percent Alaskan
pollock.” While pollock is a member of the cod family, it is a cheap
product with a very different nutritional profile than codfish, and is
commonly substituted in “cod liver oils” coming out of China and other
countries. It is a favorite of Big Food, which turns it into fish
sticks, fried fish, and other fishy substances found in processed,
packaged and fast foods. The livers are primarily sold for use in pet
food. So much for truth in labeling.
- FCLO was tested for trans fats. The
lab showed 3.22 percent trans fats, of which Dr. Gjermund Vogt, a
leading authority on fish oils, says: “No authentic raw or mildly
processed cod liver oil will contain trans fats [indicating] that
another oil has been added to this oil.” The evidence indicates that the
most likely explanation is that a heat damaged vegetable oil has been
- Joan Grinzi, Executive Director of
the Price-Pottenger Nutrition Foundation, says: “It’s taken us over a
year to thoroughly search the archives. We can now state that Dr. Price
never mentioned fermented cod liver oil and never recommended a
product like it.” FCLO is neither a true “traditional” cod liver oil nor
the “high vitamin cod liver oil” recommended by Dr. Price.
- Dr. Price pointed out the danger of
rancidity in the cod liver oils of his day, and he cited other
researchers from the 1920s and 1930s who had “called attention to the
importance of considering the toxic substances in cod liver oils as
possible explanation for differences in the results obtained by
different workers in vitamin studies.” Clinicians observed “severe and
striking” effects, most notably “serious structural damage” to the
heart and kidneys.
- Green Pasture Butter Oil showed very
good levels of Vitamin K2. So too did grass-fed ghee – which costs
about one-seventh as much. Green Pasture claims its butter oil is from
the “milk of cows that graze on select grasses of the Northern Great
Plains.” In fact, evidence indicates that for several years the company
has imported its butter in large canisters from Argentina, which
visitors to Green Pasture have reported sit around and heat up in his
solar facility. Many butter oil connoisseurs have commented that the
product has gone downhill over the past several years, with “off
flavors” and an “odd texture.”
- Lab testing of the butter oil showed a
Peroxide Value of 3.6 meq/kg. The value should be no higher than 0.6
meq/kg. Acid Value tested at 3.0 mg-KOH/g. The value should be no
higher than 0.796 mg KOH/g. Both of these tests show significant
