Study: Coffee protects against Alzheimer's and Parkinson's

Protective effect against neurodegenerative diseases from coffee

The healing and protective effects of coffee have long been suspected. A science report from the Institute for Scientific Information on Coffee confirmed that regular coffee consumption can protect against neurodegenerative diseases such as Alzheimer's and Parkinson's.

A recent report from the Institute for Scientific Information on Coffee (ISIC) highlights the potential role of coffee consumption in reducing the risk of neurodegenerative diseases such as Alzheimer's and Parkinson's. "Consuming coffee can reduce the risk of Alzheimer's and Parkinson's," the researchers write.

Increasing risk from Alzheimer's

Over time, people's life expectancy has increased significantly. However, there is a disadvantage, as the risk of illness and disability increases with age. The number of people with Alzheimer's worldwide is increasing. Around 47 million people are currently suffering from the disease, by 2030 it is expected to reach 75 million, and by 2050 the disease could affect 132 million people.

Lifestyle has a major impact on risk of neurodegenerative diseases

But Alzheimer's isn't just a neurodegenerative disease that many people already suffer from today. Parkinson's disease, the second most common age-related neurodegenerative disease, affects approximately seven million people worldwide. Research has shown that lifestyle can be an important part of the risk for neurodegenerative diseases for which curative treatment is currently not available.

How do coffee and caffeine work?

In their current study, the researchers focused on the role of food ingredients, including coffee and caffeine, in reducing the risk of neurodegenerative diseases.

Do phytochemicals and polyphenols lead to the protective effect?

The current report examines the mechanisms responsible for the positive relationship between coffee consumption and Alzheimer's and Parkinson's diseases. The role of caffeine and other herbal compounds in coffee, such as phytochemicals and polyphenols, is of particular interest.

Dietary patterns affect the risk of neurodegenerative disorders

The researchers found that eating patterns can have an impact on the risk of developing neurodegenerative disorders. This highlights the importance of a healthy diet for a healthy body and mind.

Coffee protects against neurodegenerative diseases

The consumption of coffee can really help to reduce the risk of neurodegenerative diseases in humans or to alleviate symptoms that already appear, the researchers report in a press release.

More research is needed

It is believed that men could benefit from coffee consumption more than women. One possible reason for this gender difference is that estrogen may compete with caffeine. Further investigations are necessary for a better understanding of the relationships. (as)
