Study reports “ No compelling evidence was found for an association between dairy products or vitamin D intake and PD risk indicating a potentially limited relevance of dairy intake in PD risk than previously described.”
I minimized dairy for a while but found I do better with it in my diet. So this is reassuring.
Another conflicting observation...
I can tolerate small amounts of dairy but a lot of dairy seems to make things worse.
What I take away from this study is that if you don't have PD and consume dairy products, you can relax..... odds are, you're not going to get it. What it doesn't address (that's more relevant to our interests) is what dairy does to progression in those who already have PD or RBD. Laurie Mischley's results in this regard indicate dairy's a "no no," so we'll continue to stay away.
In the section of this paper entitled "biological explanation," the authors state; "It has been shown that a significant proportion of organic environmental chemicals can bioconcentrate in milk and adipose tissue [32, 33]. Therefore, the accumulation of pesticides represents a plausible mechanism through which the association between dairy product consumption and PD risk in previous studies could be explained. In the present study, no evidence for an association between dairy intake and PD could be observed. One potential explanation for this is that, particularly when considering this plausible mechanism, the present cohort may have been exposed to different levels of pesticides present in the dairy products they consumed."
So one possibility for the widely discrepant conclusions of different studies is that pesticide levels in dairy vary widely, as does people's ability to neutralize those chemicals. I'm guessing PwP are probably among the least able to do so.
Editing this to add; A more careful read of this study suggests people in the UK should be alarmed by it. "In this study, we found no notable evidence for an association of PD risk with the consumption of dairy products or dietary vitamin D intake in the large EPIC4ND sub-cohort. However, we found a positive association between dairy consumption and PD risk when solely examining the UK cohort."
I always thought the blanket "no dairy" was misguided and based on weak data.
I have fermented dairy (and I have a tub of ice cream [with real sugar and few ingredients] about every 10 days).
I found this study: Intake of Fermented Dairy Products Induces a Less Pro-Inflammatory Postprandial Peripheral Blood Mononuclear Cell Gene Expression Response than Non-Fermented Dairy Products: A Randomized Controlled Cross-Over Trial: sci-hub.se/10.1002/mnfr.202...
According to this trial, fermented dairy products are less pro-inflammatory than non-fermented dairy products. They compared fermented products (cheese and sour cream) with non-fermented products (butter and whipped cream). "In this study, we have shown that intake of a high-fat meal composed of fermented dairy products, and especially cheese, has a less pro-inflammatory effect than intake of the non-fermented butter and whipped cream".
Okay, I also still use butter (which is allowed on the SCD) and per this study, I can keep my sour cream.
