And they even go on to say that since there was no association found, this might indicate there is even some protection from increased SFA, at least in subgroups.
Well, as we all know, there are hundreds of studies showing many things, usually ending by saying that further investigation is needed to confirm results.
But...if you are in a position such as Pratoman or myself, then you have to make choices based on the best available information.
This study used quartiles. The diet that these subject consumed...even in the lowest quartile is nothing like that consumed in the Ornish or Esselstyn.....two of the studies, albeit small by comparison, that showed results for those with existing blockages.
We try to figure out what will work for us going into the future while knowing that each individual is unique.
So look at the "lower fat" quartile used in this study. The fat as a percentage of calories was 25%.
In the Ornish and Esselstyn studies, the goal was under 10%. The range from the lower fat quartile to the high fat quartile was 25% to 37%.... The Ornish study over 5 years was 8.4%
Cholesterol intake in this study ranged from 229mg to 357mg whereas in the Ornish study they averaged 18.6 grams.
In other words, the diets of those who showed the improvement in the Ornish study were eating in a manner that was like on another world compared to what was reported in this study we are discussing.
The comparing the lowest quartile with the highest quartile.... then suggesting that given that observation that the same might hold true, even if comparing it to the Ornish level of diet, is a step too far for me.
I have to eat now. I have to choose the program that offers me the best hope and has some evidence to back it up. If i thought for a moment that eating more fat of all types would offer me a better outcome, I'd change tomorrow.
There are no guarantees and every individual is different. Not unlike when people are choosing treatments for prostate cancer.
One of the problems that some have mentioned here is that we don't have a large 1,800+ size....5 year trial showing that a ultra low fat diet, where the subjects are fairly selected and randomly assigned to a normal or low fat diet. We will never have such a study... In large part because you can't find people who are willing to be assigned to a 10% diet for 5 years. The dropouts would be 90% and the adherence of those who remained would be very poor.
It will never happen yet that is one of the arguments some throw at this dietary very low-fat choice.
I don't think this study we are discussing solved that problem because a 25% fat diet is very close to normal, though I imagine the participants on the lowest quartile were eating a bit like they were trying to be "heart healthy" given that they were already CAD patients and almost half of them (44%) had already had one heart attack.
So, I don't know this study gives us much to go on. More like some nuances in the normal dietary realm as opposed to a comparison of outcomes in a true effort at very low-fat dietary intervention.
I have only one blockage in one spot. I have thus far chosen to not have a stent placed. I may change my mind. I do a significant amount of cardio exercise and experience temporary initial mild angina every time between minutes 3 and about
15- 20... I don't stop my exercise and then it goes away for the most part as I continue.
But the daily exercise angina has not gone away. So perhaps I am halting progression but not reversing anything. Can't run down and get a angiogram every few months.
I have to make a choice on how I eat now.
I can assure you I have read a huge amount of information from hundreds of sources...
I find nothing in the high fat/ low carb message that makes me want to risk going that route.
I find that no one in that huge movement has taken the time to take 100 CAD patients and place them on a high fat diet to see what the outcome will be.
So we end up with studies that keep looking at not-very-low-fat diets compared to normal-fairly high-fat diets, then try to draw some inference that if the line continued on the graph it would show such and such for the very-low fat diets.
Fairly weak ideas result.
I'll keep a
open mind as I continue studying the various sources of information. Nothing in the world would be easier than to just revert back to a higher fat diet.
I don't accept all the claims of Ornish, Esselsstyn, McDougall, Fuhrman, T. Colin Campbell, and the dozens of others who make the low-fat case.
But when you end up with everything on the table, you have to make a choice.
Thus far the ultra lower fat, higher complexed carbs, no dairy, lifestyle offers the hope of better results for those looking to do something to improve their odds over years and years.
It may be that at some level of lower fat, you cross a threshold of benefit where things begin to behave differently in your arteries. It may be that 25% is not nearly low enough to achieve such benefits.
Not unlike those on low carbs that finally reach the "promised land" of ketosis.
Much mystery surrounds all of this, compounded by the fact that every individual is unique.
Stanford professor Christopher Gardner is studying just that feature. That different individuals behave differently on various diets. What works for one is the opposite of what achieves results for others.
You lay down your money and place your bets. I'm going the Ornish route until and unless someone comes up with something different for CAD patients that offers more hope.
