Yeah, I read the first study because it seemed crazy.
TFA:
"The group consuming more vegetable oil had a 62% higher rate of death during the seven-year study compared to the group eating less vegetable oil. . .To put that into perspective, of the commonly cited diet and lifestyle risk factors, only severe obesity and heavy smoking are more dangerous"
The study in question, emphasis mine:
n=458
"Eligible patients were men aged 30-59 years admitted . . . for an episode of acute myocardial infarction (86%), or acute coronary insufficiency or angina (14%) . . . The intervention group received instructions to increase their PUFA [PolyUnsaturated Fatty Acid] intake to about 15% of food energy, and to reduce their intake of SFA[Saturated Fatty Acid] and dietary cholesterol to less than 10% of food energy and 300 mg per day, respectively. To achieve these targets. . . Liquid safflower oil was substituted for animal fats, common margarines and shortenings in cooking oils, salad dressings, baked goods, and other products, and was also taken as a supplement. . .Safflower oil is a concentrated source of [Omega]-6 LA and contains no other reported PUFAs Therefore, the intervention oil selectively increased [Omega]-6 LA without a concurrent increase in [Omega]-3 PUFAs."
TFA represents it as a population wide conclusion about all "vegetable" oils, and then has the audacity to directly compare this misrepresentation to the results of large scale longitudinal and prospective studies, comparing it to a sedentary lifestyle, smoking, etc. Absolutely ridiculous. Like I actually think that's a valuable study to have read, but the Author's article is being sensationalist and dishonest with their representation.
FWIW as someone who reads a fair amount about nutrition to the point I consider it a hobby; I don't find this result on Safflower oil surprising, but the sensationalism in TFA is insane. There is a lot to unpack with that study–do people who have these problems have biological processing or other confounding factors that make high Omega-6:Omega-3 diets unhealthy, is there something specifically bad about linoleic acid, or perhaps about a fatty acid regimen of primarily linoleic acid?
