US EditionParkinson's disease prevention may 'begin at the dinner table'
- A new study published in Neurology links high consumption of ultraprocessed foods to early signs of Parkinson's disease in nearly 43,000 U.S. Adults.
- Researchers examined extensive dietary and health records collected over many years from nearly 43,000 participants in two large U.S. Cohorts focused on health behaviors, all of whom were initially free of Parkinson’s disease.
- The study revealed that individuals consuming around 11 servings of ultraprocessed foods daily—such as sugary sodas and packaged snacks—were more than twice as likely to show three or more early symptoms associated with Parkinson's disease compared to those eating only three servings.
- Dr. Xiang Gao, the senior author, emphasized that Parkinson's disease cannot be cured and suggested that supporting brain health may involve reducing intake of processed items while increasing consumption of nutrient-rich, minimally processed foods.
- While the study did not confirm higher Parkinson's diagnoses later, it suggests diet may influence neurodegeneration and supports prevention strategies beginning with nutrition.

Machine learning-based meta-analysis reveals gut microbiome alterations associated with Parkinson’s disease
There is strong interest in using the gut microbiome for Parkinson’s disease (PD) diagnosis and treatment. However, a consensus on PD-associated microbiome features and a multi-study assessment of their diagnostic value is lacking. Here, we present a machine learning meta-analysis of PD microbiome studies of unprecedented scale (4489 samples). Within most studies, microbiome-based machine learning models accurately classify PD patients (average …

Ultra Processed Foods May Accelerate Parkinson's Brain Changes
A large new study shows that consuming high amounts of ultra processed foods may be linked to early indicators of Parkinson’s disease. Researchers tracked over 42,000 adults for up to 26 years, finding that those eating 11 or more daily servings of ultra processed foods were 2.5 times more likely to show multiple prodromal Parkinson’s symptoms.
