The impact of diet on Parkinson's disease risk: A data-driven analysis in a large Italian case-control population

Parkinson's disease (PD) is a neurodegenerative disorder that affects millions of people worldwide. Scientists are still studying what causes PD, and some think that diet might play a role. In our study, we looked at how different eating habits might be linked to PD. We asked 680 people with PD and 612 people without PD about their food consumption habits. Then, we grouped these foods to see if certain eating habits were more common or uncommon in people with PD. We found that people who often ate sweets, red meat, and processed meats had a higher chance of having PD. On the other hand, people who ate a lot of fruit seemed to have a lower risk. However, we also found that other factors—such as family history, exposure to pesticides, oils, metals, and general anesthesia—had a bigger effect on PD risk than diet alone. This study suggests that eating habits might have some impact on PD, but they are not the main cause. Future research should look at both diet and other lifestyle habits to better understand how to prevent PD.
