Laut Studie wird ungesüßter Kaffee mit einem verringerten Risiko für Alzheimer und Parkinson in Verbindung gebracht | Dieser Zusammenhang wurde bei gesüßtem oder künstlich gesüßtem Kaffee nicht beobachtet

From the article: Recent [research](https://doi.org/10.1016/j.ajcnut.2024.08.012) has found that older individuals with a higher intake of caffeinated coffee, particularly the unsweetened variety, are less likely to suffer from Alzheimer’s disease, related dementias, and Parkinson’s disease. This association was not observed for sweetened or artificially sweetened coffee. The research was published in the American Journal of Clinical Nutrition.

Alzheimer’s and Parkinson’s diseases are the most common neurodegenerative disorders and are among the leading causes of disability and dependency in aging populations worldwide. Estimates indicate that these conditions currently affect over 63 million people globally.

Alzheimer’s disease is a progressive neurological disorder that impacts memory, thinking, and behavior, making it the most common cause of dementia. It typically begins with mild memory loss and gradually worsens, interfering with daily life and independence. The disease is characterized by the accumulation of amyloid plaques and tau tangles in the brain, which lead to the death of brain cells. While there is no cure, treatments focus on managing symptoms and improving quality of life.

Parkinson’s disease is a progressive neurological disorder that primarily affects movement due to the degeneration of dopamine-producing neurons in the brain. Common symptoms include tremors, stiffness, slow movement (bradykinesia), and balance difficulties, which worsen over time. Non-motor symptoms, such as sleep disturbances, depression, and cognitive changes, can also occur.

Study author Tingjing Zhang sought to examine the associations between coffee consumption and the risk of neurodegenerative diseases. Unlike previous studies, this research also considered the type of coffee consumed.

The researchers analyzed data from the UK Biobank, a large-scale biomedical database containing health, genetic, and lifestyle information from approximately 500,000 individuals living in the United Kingdom. This resource is available for research analyses to researchers worldwide.
