Foods That Could Accelerate Parkinson’s Symptoms: What Experts Want You to Know
Recent research has brought to light a concerning connection between the consumption of ultraprocessed foods and the acceleration of early signs of Parkinson’s disease. These foods, which include items like pre-packaged baked goods, sodas, potato chips, and processed meats such as hot dogs and salami, are already known for their adverse health effects, including increased risks of colon cancer, dementia, and premature death.
A study published in the journal Neurology has now added to this list, suggesting that a diet rich in ultraprocessed foods might also exacerbate the early symptoms of Parkinson’s disease. These initial symptoms occur during the prodromal stage, the earliest phase of Parkinson’s when neurodegeneration begins. This stage can precede the more recognizable symptoms like tremors and balance issues by years or even decades.
The study analyzed health data from 42,853 U.S. participants with an average age of 48, none of whom had a history of Parkinson’s. Over several decades, these participants reported their dietary habits and underwent regular medical examinations. From 2012 onwards, they also reported symptoms associated with prodromal Parkinson’s disease.
The findings were significant. Researchers discovered that long-term consumption of ultraprocessed foods was “positively associated” with the symptoms of prodromal Parkinson’s. “Participants who ate the most ultraprocessed foods were about 2.5 times as likely to have at least three early symptoms of Parkinson’s disease compared with those who consumed the least,” according to The New York Times.
While these symptoms do not guarantee the development of Parkinson’s disease, they may indicate underlying brain changes that could eventually lead to a diagnosis. As Xiang Gao, MD, PhD, from the Institute of Nutrition at Fudan University in Shanghai, stated, “Our research shows that eating too much processed food, like sugary sodas and packaged snacks, might be speeding up early signs of Parkinson’s disease.”
However, it’s crucial to understand that this study does not establish a direct causative link between ultraprocessed foods and Parkinson’s. Gao emphasized the need for further research, stating, “More studies are needed to confirm our finding that eating less processed food may slow down the earliest signs of Parkinson’s disease.”
Emerging research also suggests that Parkinson’s disease might originate in the gut before affecting the central nervous system and brain. Trisha S. Pasricha, a neurogastroenterologist, noted that many individuals with Parkinson’s experience gastrointestinal symptoms like constipation and nausea long before motor symptoms appear.
The potential connection between ultraprocessed foods and Parkinson’s could be due to increased inflammation and cellular damage these foods cause. A study published in the journal Movement Disorders found elevated levels of brain inflammation in Parkinson’s patients, a finding also highlighted by the Parkinson’s Foundation.
Moreover, diets high in ultraprocessed foods often lack essential nutrients, which could contribute to vitamin deficiencies linked to an increased risk of Parkinson’s. As research continues to unfold, the relationship between diet and neurological health remains a critical area of study.
