I think this is correct. We have known for some time that Lewy Bodies have been found in the gut, and before PD symptoms appeared. Why are they there, though? A virus, bacteria, or, more likely, as the recent study showing PWP had a significantly different gut biome than non-PWP, an imbalance of good gut biome to bad. As more and more research comes out about this, I think we may really begin to understand the importance of "you are what you eat". And its corollary: you are also how much you eat
