Saturated Fat: Dueling studies. Who's right?

Answered on August 19, 2014
Created April 08, 2013 at 4:09 PM

I sent a friend this link: http://chriskresser.com/for-a-healthy-heart-stick-to-butter

He writes back saying:

"The only problem is that you keep hearing about mainstream studies like the two below that suggests otherwise:

http://ajcn.nutrition.org/content/early/2012/11/27/ajcn.112.048991

http://www.ncbi.nlm.nih.gov/pubmed/20634591

"

Who's right?

Please help me convince him that saturated fat is better than refined omega 6 oils .

Thx Mike

Sure, confounding factors and all that, but try being born after everyone/every corporation switched to vegetable oils. I can feel it killing me when I eat concentrated sources, I swear to you. At age 18 I felt like I was dieing and purely by eating more meat and saturated fat I feel alive again. No study will EVER convince me that concentrated/refined O-6 oils are healthy for everyone.

If I read that questionnaire, yes. I subscribe to the saturated fat health idea because it makes sense from an evolutionary standpoint of food availability, though there do seem to be some decent controlled studies supporting it too. There would also seem to be some decent ones in support of PUFA so I subscribe to more logical(in my opinion) choice. That and the fact that my generation is so terribly unhealthy, and that I feel much better when limiting PUFA. I've seen my elderly family develop blood pressure/coronary problems after switching to vegetable oil as well.

What if the study had found that saturated fat was associated with better health? Would you still think it was useless?

Yes, it is better than refined omega 6 oils. Just like sweet potatoes are better then bleached white flour (another highly refined food). I doubt it's better than whole nuts though.

I absolutely believe you're correct, because many people in the paleosphere swear by coconut oil and it doesn't agree with me while I can drown in beef fat with no problem. Pork and chicken fat are fine only in moderate-low amounts while butter doesn't seem to be an issue. So, as always, we're highly variable and shouldn't preach to each other.

Here's one study that may help:

http://www.ncbi.nlm.nih.gov/pubmed/23386268

I think the worst thing about refined n6 is it's correlation with higher all cause mortality(cancer?). In the LA Veterans study saturated fat and pufa diets were compared and after about the seven year mark people in the pufa group started to die at an accelerated rate. You can see the same thing in the Minnesota coronary survey after the 4 year mark, all cause mortality starts to rise in comparison to the Sat fat group. These are the only two double blind studies that control for those two types of fat only, that I know of.

I don't think there will be anymore long term studies comparing the two just because of the perceived danger of a long term high n6 oil diet. IMO if they had kept those trials going it would of been ugly.

Without even reading those studies in depth, I don't see what they prove in relation to fat intake.

Study 1: It found no increase in heart failure risk with higher O-6 consumption. Is it taking O-3 into account? Is a higher O-6 plasma concentration relevant to systemic effects of O-6 consumption? What other dietary factors may have been overlooked?

I don't know the answers to these questions because the full study isn't viewable...

Study 2: The study is based on a questionnaire. Here is the most updated version of it:

http://riskfactor.cancer.gov/dhq2/forms/dhq2_pastyear.pdf

How well do you trust average people to report their PUFA intake? Do you really believe the average person even knows? Even if they did, it would not be easy to report in that questionnaire considering the variability of the food products listed. I wouldn't trust any specific nutrient data based on the silly questionnaire. Seriously, go read it.

I don't think that saturated fat is better than not refined omega 6 oils. Why? Some people (like me) react to saturated fat. So we (people who are sensitive to it) need to reduce its consumption. I don't have any studies to confirm it, I just know how I personally react to it. I also do not know what makes me (and other people like me) react to it.
