Study Links Dairy Intake to Parkinson’s Risk

A recent study has found that higher dairy consumption—particularly milk—may be associated with an increased risk of Parkinson’s disease, adding to ongoing scientific debate around diet and neurodegenerative disorders. The findings are based on observational research analysing large population datasets, highlighting a potential link rather than a confirmed cause.

The analysis covered over 6.34 lakh participants across multiple studies, identifying 4,285 Parkinson’s disease cases, and found that individuals with higher dairy intake had a 21% higher risk (RR: 1.21) of developing the disease compared to lower consumers.

The association appeared stronger in men, with risk estimates rising to 28% higher (RR: 1.28), while no significant link was observed in women, indicating possible biological or lifestyle differences influencing outcomes.

Milk consumption specifically was also linked to increased risk, with a 13% higher likelihood (RR: 1.13), whereas no significant association was found for yogurt, cheese, butter, or ice cream, suggesting variation across dairy categories.

Researchers noted that the mechanism remains unclear, with hypotheses ranging from gut-brain axis interactions to environmental contaminants, and emphasized that the findings are observational and do not establish causation.

Experts continue to stress that dairy products provide essential nutrients, and further research is needed before making any major dietary recommendations, as the evidence remains inconclusive and evolving.
