The 1971 Danish study on Inuit and the 2014 findings are real. The reel exaggerates flaws, pushes ratios beyond sources, and calls fish oil useless for almost all when exceptions exist.
Why we say that›
1971 Inuit study real but overstated as total myth. Fish oil has limited benefits per later data.
Facts on the 1971 expedition, chemists not cardiologists, death certificate method, 2014 similar heart disease rates, low ALA conversion, and pregnancy DHA recommendation hold up. Sunflower oil ratio over 100:1 lacks direct support and is overstated. Through-line follows but characterization stretches the original study's limits and ignores targeted medical uses.
Based on only a few sources, so read this as a first look, not the last word.
The original 1971 study noted very low heart disease rates in death records despite high smoking and obesity. Later studies confirm higher stroke rates but the correlation observation was not unsupported.

Claims
3 true · 8 unchecked
- Couldn't check
Two Danish scientists sailed to Greenland in 1971 and drew blood from 130 Inuit people
What's actually true
We couldn't verify this claim with a reliable source. Supported by reports on the 1971 Lancet paper expedition.
- Couldn't check
The 1971 study found low cholesterol and connected it to the Inuit diet high in fish
What's actually true
The study linked low cholesterol to the fish-rich diet.
- True
The two Danish scientists in the 1971 Greenland study were chemists, not cardiologists
- True
The 1971 scientists never examined a single Inuit heart and got heart disease numbers from death certificates in a remote region
What's actually true
They used death certificates and hospital data. Many lacked doctor examination in remote areas.
- True
A 2014 study found that Inuit have heart disease at roughly the same rate as everyone else
What's actually true
2014 review found coronary artery disease prevalence similar to other populations.
- Couldn't check
A meta-analysis of 10 trials involving 78,000 people published in JAMA Cardiology found no meaningful heart benefit from fish oil supplements
What's actually true
We couldn't verify this claim with a reliable source. Large trials and reviews, including around this scale, show limited or no meaningful heart benefits.
- Couldn't check
The human body converts plant-based ALA omega-3 to DHA at a rate under 1%
What's actually true
Conversion of ALA to DHA is on the order of 1% or lower in adults.
- Couldn't check
Refined sunflower oil has an omega-6 to omega-3 ratio of over 100 to 1
What's actually true
We couldn't verify this claim with a reliable source. Typical ratios are high at 40:1 to over 80:1 but searches did not confirm over 100:1 specifically for refined sunflower.
- Couldn't check
Cold pressed mustard oil has an omega-6 to omega-3 ratio of 2.5 to 1
What's actually true
We couldn't verify this claim with a reliable source. This matches known fatty acid profiles for mustard oil.
- Couldn't check
Medical recommendation for vegetarian pregnant women is 200 milligrams of DHA per day
What's actually true
Societies recommend increasing DHA by 200 mg/day during pregnancy.
- Couldn't check
Fish obtain omega-3 from algae
What's actually true
Fish get omega-3 from algae as the original source.
The full story, from the sources›
They concluded that the conversion of ALA to DHA is on the order of 1% in infants, and considerably lower in adults. - pmc.ncbi.nlm.nih.gov (2009) Bang and Dyerberg were clinical chemists at Aalborg Hospital North in Denmark. Curious about the nutrition of the Inuit, they “undertook an expedition to the northwest coast of Greenland, which they described in a 1971 Lancet paper. The researchers drew blood from 130 natives. - Slate Magazine (2014-08-04) Bang and Dyberg relied on heart-disease statistics provided by Greenlands chief medical officer for the years 1963-1967 and 1973-1976 — statistics that fell far short of telling the entire heart-disease story of the Inuit [...] These reports were based on death certificates and hospital admissions. Concerns over the validity and accuracy of death certificate and mortality statistics in Greenland have been raised in a number of reports. Thus, 20% of death certificates were completed without a doctor having examined the patient or the body. - MinnPost (2014-08-13) Curious about the Inuits’ nutrition, they “undertook an expedition" to the north-west coast of Greenland, which they described in a 1971 Lancet paper. - Australian Financial Review (2014-09-18) Scientific societies recommend increasing intake of docosahexaenoic acid (DHA) by 200 mg / day during pregnancy. - pmc.ncbi.nlm.nih.gov (2020)
From reporting
What else it leaves out (2)›
- Fish oil supplements show some benefits in specific high-risk groups or for triglycerides per medical guidelines, though not broad heart disease prevention.
- The reel omits that many modern recommendations focus on dietary fish over supplements for general health.
