According to available evidence, consuming coffee decreases the chance of acquiring Parkinson's disease by up to 30% in a dose-dependent way, with most research showing that three cups of coffee is the beneficial dose. However, more research is needed to establish exactly how coffee prevents neurodegeneration and supports brain health. Parkinson's disease is a chronic condition that affects the nervous system and causes problems with muscle control. As the disease progresses, it can lead to severe issues with walking and talking. The cause of the disease is not known but it appears to be influenced by genetic factors and environmental triggers. Studies have shown an association between Parkinson's disease and other disorders such as diabetes, obesity, and smoking. Therefore, it is recommended that people with Parkinson's disease avoid these risks by eating a healthy diet and being active. Coffee contains several compounds that may protect against neurodegeneration and support brain health. These include chlorogenic acids, trigonelline, and caffeine. Chlorogenic acids are polyphenols found in coffee that have many health benefits for individuals who consume them. In studies conducted on mice, they have been shown to prevent neurodegeneration caused by neurotoxins and help improve memory and cognitive function. Trigonelline is another compound in coffee that has been shown to have similar properties.
