US EditionUltra-Processed Foods Linked to Early Signs of Parkinson's Disease
- Researchers published a 2025 study showing that people consuming 11 or more servings of ultra-processed foods daily had increased early Parkinson's signs in the US and UK.
- This longitudinal study analyzed diet and health from nearly 43,000 participants tracked up to 26 years to find associations, not causation, between processed food intake and prodromal Parkinson's features.
- Higher ultra-processed food consumption linked to 2.5 times greater likelihood of having three or more early Parkinson's signs, excluding constipation, compared to eating fewer than three servings daily.
- Experts including Dr. Xiang Gao and neurologist Jessica Ng emphasize that dietary choices affect brain health and recommend reducing processed foods and increasing whole foods to possibly delay Parkinson's onset.
- The findings highlight the potential importance of diet as a modifiable risk factor for Parkinson's disease and suggest further research is needed to clarify these relations and effective preventive strategies.
