Low Vitamin B6 May Raise Parkinson’s Disease Risk

In that a link has been suggested between B vitamin intake and Parkinson’s disease via the homocysteine pathway, Kentaro Murakami, from the University of Tokyo (Japan), and colleagues conducted a hospital-based case-control study involving 249 people with Parkinson’s disease, matching them to 368 people without any neurodegenerative condition.  The team compiled data relating to B-vitamin intake via dietary questionnaire. Noting that: “Low intake of vitamin B6 was associated with an increased risk of [Parkinson’s Disease], independent of potential dietary and non-dietary confounders,” the team writes that:  “In conclusion, in the present case-control study in Japan, low intake of vitamin B6, but not of folate, vitamin B12 or riboflavin, was independently associated with an increased risk of [Parkinson’s Disease].”
