We have previously discussed the importance of the right foods for people with Parkinson’s on this blog – Click here for a good example.
Recently, new data from researchers in Sweden points towards the benefits of a specific component of fish in particular.
It is a protein called β-parvalbumin, which has some very interesting properties.
In today’s post, we discuss what beta-parvalbumin is, review the new research findings, and consider how this new information could be applied to Parkinson’s.

In 2003, researchers found 34 bone fragments belonging to a single individual in a cave near Tianyuan, close to Beijing (China).
But it was not the beginning of a potential murder investigation.
This was the start of something far more interesting.
Naming the individual “Tianyuan man”, the researchers have subsequently found that “many present-day Asians and Native Americans” are genetically related to this individual. His bones represented one of the oldest set of modern human remains ever found in the eastern Eurasia region.

But beyond the enormous family tree, when researchers further explored specific details about his jaw bone (or lower mandible as it is called) they found something else that was very interesting about Tianyuan man:
Title: Stable isotope dietary analysis of the Tianyuan 1 early modern human.
Authors: Hu Y, Shang H, Tong H, Nehlich O, Liu W, Zhao C, Yu J, Wang C, Trinkaus E, Richards MP.
Journal: Proc Natl Acad Sci U S A. 2009 Jul 7;106(27):10971-4.
PMID: 19581579 (This research article is OPEN ACCESS if you would like to read it)
In this study, the investigators analysed the carbon and nitrogen isotopes found within bone collagen samples taken from the jaw bone of Tianyuan man. In humans, the carbon and nitrogen isotope values indicate the sources of dietary protein over many years of life.
The researchers found that a substantial portion of Tianyuan man’s diet 40,000 years ago came from freshwater fish.
Interesting preamble, but what does this have to do with Parkinson’s?
They say that “we are what we eat”, and food can certainly have a major impact on health and wellbeing.
Recently, a research report has been published that looks into the topic of food in the context of Parkinson’s disease.
And the results are interesting.
In today’s post we will outline the new research, discuss the results, and what they mean for people living with Parkinson’s disease.

Established in 1978, Bastyr University is an alternative medicines institute.
The original campus (Bastyr now has a second campus in San Diego, California) is tucked into the idyllic forested area of Saint Edward State Park on the edge of Lake Washington, just north-east of downtown Seattle (Washington).
Hang on a moment – ‘alternative medicines’?
While I can understand that some readers may immediately question why ‘alternative medicines’ are being mentioned on the “Science” of Parkinson’s disease website, here at the SoPD HQ we entertain any and all ideas with regards to Parkinson’s disease. And we are certainly open to any data that may be of interest to the Parkinson’s community.
Particularly, when that data comes from this individual:
This is Dr Laurie Mischley. She’s awesome.
She is an Associate Clinical Investigator at Bastyr University, a guru when it comes to nutrition, and our first port of call when we field questions regarding Parkinson’s disease and diet. You can see her in action in this video (recommended viewing for those with Parkinson’s disease and interested in the topic of diet/nutrition):
Importantly, Dr Mischley is also responsible for most of the clinical study data that we have on Acetylcysteine (also known as N-acetylcysteine or simply NAC) in Parkinson’s disease (Click here to read more about this).
And she is currently co-ordinating the “Complementary & Alternative Medicine Care in Parkinson’s Disease” (CAM Care in PD) study, which is attempting to ‘collect as much data as possible over a five-year period with the hope of finding dietary and lifestyle factors associated with a slower disease progression’. The study is still recruiting and I would encourage readers to take time to enrol in the study and fill in the survey (Click here to learn more).
This ongoing CAM study (and Dr Mischley’s efforts) has recently borne fruit that will be of real interest to the Parkinson’s community. It is a research report that reviews dietary and nutritional supplemental factors that can impact Parkinson’s disease progression.
