A new study has revealed a potential link between frequent consumption of highly processed foods and an increased risk of developing early symptoms associated with Parkinson’s disease.
Researchers from Fudan University in China conducted a long-term investigation involving approximately 43,000 adults, tracking their health and dietary habits over a 26-year period. Participants underwent regular medical assessments and completed health and nutrition questionnaires every two to four years.
The study found that individuals who regularly consumed large amounts of ultra-processed foods—such as sausages, sugary breakfast cereals, and sweetened fizzy drinks—were significantly more likely to experience early signs linked to Parkinson’s disease. These symptoms included sleep disturbances, depressive tendencies, generalised body aches, visual problems, reduced sense of smell, and excessive daytime sleepiness.
According to the findings, participants who consumed 11 or more types of ultra-processed foods or drinks per day were two and a half times more likely to exhibit three or more early symptoms of Parkinson’s disease, compared to those who consumed fewer than three such items daily.
While the researchers emphasised that the study does not definitively prove that ultra-processed foods cause Parkinson’s, it does highlight a strong correlation that warrants further investigation.
The lead researcher noted that, although more studies are needed to confirm a causal relationship, it is advisable to limit the intake of ultra-processed foods and focus on healthier dietary choices to support overall brain and body health.
