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.

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?
