Replacing Butter With Vegetable Oils Doesn't Decrease Risk of Heart Disease, Says Study (medicalxpress.com)
An anonymous reader writes: A research team led by scientists at the UNC School of Medicine and the National Institutes of Health has unearthed more evidence that casts doubt on the traditional "heart healthy" practice of replacing butter and other saturated fats with corn oil and other vegetable oils high in linoleic acid. The findings, reported today in the British Medical Journal, suggest that using vegetable oils high in linoleic acid might be worse than using butter when it comes to preventing heart disease, though more research needs to be done on that front. This latest evidence comes from an analysis of previously unpublished data of a large controlled trial conducted in Minnesota nearly 50 years ago, as well as a broader analysis of published data from all similar trials of this dietary intervention. The analyses show that interventions using linoleic acid-rich oils failed to reduce heart disease and overall mortality even though the intervention reduced cholesterol levels. In the Minnesota study, participants who had greater reduction in serum cholesterol had higher rather than lower risk of death. Two things to note about the study: 75% of the participants left in less than a year (perhaps not uncommon, the study doesn't explain why these people left); the vegetable oils mentioned in the article are not necessarily the most commonly used (which are oils made of olive, sunflower, coconut, and palm).
I don't care so much as whether the science is settled so much as dogmatic people that have a certain viewpoint on eating habits that they're hell bent on getting people to follow. Take for example militant vegans who proclaim "there's no reason to eat animal products", or for example, a group calling itself the "Physicians Committee for Responsible Medicine" who aren't actually physicians, and are in fact just another PETA (with very close ties to PETA) who just sued the FDA because they no longer recommend a daily limit on cholesterol, which was a huge setback to the anti-egg movement.
And while vegans can be militant food activists, they aren't alone. The other group is what I term the "food religion", which is pretty hostile towards anybody who dares tell them that they aren't going to bother (read: waste time and money) with organic food, and are even more hostile against anybody who says heretical things such as "everything you eat is a chemical" or "GMO is safe". Or worse yet, outright trying to get laws passed to ban anything that doesn't fit a vague definition of "natural" under the mistaken belief that "natural is better".
This same group does another very annoying thing to those of us with chronic conditions: Insist that the food you eat causes whatever you might have, insist that they never get sick (and otherwise talk as if they'll live forever,) and all chronic diseases will just go away if you simply switch to organic (and one even suggested homeopathic medicine would fix it in my case.) My way of getting back at them though is that these same people are often fans of a work based on cherry picked data called The China Study, talk about how wonderful Eastern medicine (such as acupuncture) is, and so I just mention that my particular disease (stage 4 chronic kidney disease caused by IgA nephropathy) has a MUCH higher prevalence in Asian countries.
