Moderate consumption of coffee is associated with a decreased risk of depression and lower levels of Parkinson’s and dementia, according to new research.
A review of more than 200 studies have shown that drinking 3 to 4 cups of coffee a day also associated with many other advantages.
These include lower levels of heart disease, reduce the risk of certain cancers, diabetes, and liver disease.
The authors of the study write: “the Consumption of coffee has been associated with a lower risk of Parkinson’s disease. Consumption had a consistent Association with lower risk of depression and cognitive disorders, especially Alzheimer’s disease”.
Coffee has also been associated with lower risk of several cancers:
• prostate cancer
• skin cancer
• liver cancer
The risk of type 2 diabetes, gallstones, and gout was lower in those who drank coffee. Obvious effect of coffee was particularly strong for diseases of the liver such as cirrhosis. Evidence of the consumption of decaffeinated coffee was not as strong.
Writing a linked comment, Professor Eliseo Guallar, an expert in the field of public health, said: “Should doctors recommend drinking coffee to prevent disease? Should people start drinking coffee for health reasons? The answer to both questions is no.
But if you already drink coffee, then how much should you drink?
Professor Gullar explained: “… the lowest risk of disease associated with drinking three to five cups of coffee a day. Higher consumption may reduce or reverse the potential benefits, and there is significant uncertainty both in individual studies and meta-analyses on the effects of higher levels of consumption. Thus, conclusions about the safety of coffee should be limited to moderate consumption”.
