<< Billybob, isn't there evidence that saturated fat may be implicated
in PC or PC progression? >>
That appears to be the case . . . see below.
Well, then, looks like I am a goner! However, are there any conflicting studies out there? I don't know. (Actually, I know of one possible, I will copy it below) So there may indeed be a relationship between fat (saturated especially) and PC, but this of course is not proof, just an association found in this small study of 384 men diagnosed with prostate cancer between 1990 and 1992 in the Quebec City area. ot exactly RCT level evidence. Info gathered by Trained nutritionists who interviewed the men on their usual diet using a diet history questionnaire.(that type of data, I am often told, is not the most reliable) Also, I'm willing to bet that most of these men were also high carb eaters, and who can say if the highest saturated at eaters were not also the highest consumers of carb, running the old insulin right on up there. And high carb PLUS high fat may not be the best way to go, but it is a very common way to go. (NOT saying there is not a significant relationship between sat fat and PC progression, there might be, just saying this study is not much proof)
But maybe there is a relationship? I have actually seen a couple of other studies- of the same type though maybe larger- indicating much the same as your linked study. But as folks here constantly remind us, association is not causation, and until we get those studies, we won't know for sure. Or as Prato just said:
From the study linked above by CC...
there is, as yet, no published study on the relationship between diet and disease progression among prostate cancer patients
No surprise, something everyone who reads this thread knows. Yet shocking to me, that with 200,000 men (I think I hve that right) diagnosed in the US alone, and God knows how many worldwide, each year, a real actual study can't be funded by an entity like the World Health Organization. Or a consortium of developed nations.
Ain't that the truth! Wonder why no one seems to really want to know, except us guys? LOL! But, I said I found some similar studies to the one linked by CC, but it remains the same old story: how many of these folks were high carb eaters(who knows)? Did any of these studies look at the effect of a group that ate their usual amount of fat- or even more- but cut way down on non-fiber carbs? Even more important: what was the insulin and insulin resistance in the various groups? Did they look at men who ate plenty of fat, including saturated- but did not eat an abundance of carb along with it? Unlikely. And there might be a large difference in insulin production and/or resistance in 2 such groups. Which might have a significant influence on the advance of PC.
In other words: there are a lot of other possibly quite important factors and variables that I would like to see accounted for in that study on saturated fats and PC. Do Y'all remember this study out of Harvard a few years back?/www.ncbi.nlm.nih.gov/pmc/articles/PMC3132069/
Background: Processed meat and fish have been shown to be associated with the risk of advanced prostate cancer, but few studies have examined diet after prostate cancer diagnosis and risk of its progression.
Objective: We examined the association between post diagnostic consumption of processed and unprocessed red meat, fish, poultry, and eggs and the risk of prostate cancer recurrence or progression.
Design: We conducted a prospective study in 1294 men with prostate cancer, without recurrence or progression as of 2004–2005, who were participating in the Cancer of the Prostate Strategic Urologic Research Endeavor and who were followed for an average of 2 y........................
Intakes of processed and unprocessed red meat, fish, total poultry, and skinless poultry were not associated with prostate cancer recurrence or progression. Greater consumption of eggs and poultry with skin was associated with 2-fold increases in risk in a comparison of extreme quantiles
So, OK, just another study, right? But neither red meat, or even processed red meat
, total or skinless poultry- all the foods highest in saturated fats- even in the highest quantiles- had any asscociation with PC recurrence or progression. So, maybe this is a bad study, or maybe not. But if not, how can the groups eating the highest sat fat be A-OK in this study, but have significantly higher problems in the other study?
So, bottom line for me, subject to change, I don't think we have a ton of evidence on this quite yet. I could be wrong as always.
