Coffee compounds linked to reduced chronic liver disease risk

Coffee compounds that include caffeine, chlorogenic acid, kahweol and cafestol, may contribute in reducing the risk of developing chronic liver disease, according to UK researchers.

The team found drinking caffeinated ground, instant or decaffeinated coffee could reduce risk of developing and dying from liver conditions, with the health benefit peaking at three to four cups per day.

“Coffee is widely accessible and the benefits we see from our study may mean it could offer a potential preventative treatment for chronic liver disease,”​ says lead author Dr Oliver Kennedy

“This would be especially valuable in countries with lower income and worse access to healthcare and where the burden of chronic liver disease is highest.”

Researchers at the Universities of Southampton and Edinburgh began looking at data gathered from the UK Biobank study that followed 495,585 participants, over 10 years, to track any links between coffee consumption and liver complications.

Initial findings revealed 78% (384,818) drank caffeinated ground/instant or decaffeinated coffee, while 22% (109,767) did not drink any type of coffee.

During the research’s duration, the team noted 3,600 cases of chronic liver disease, including 301 deaths with 5,439 cases of chronic liver disease or steatosis and 184 cases of Hepatocellular carcinoma.

In contrast to non-coffee drinkers, coffee-drinkers had a 21% reduced risk of chronic liver disease, a 20% reduced risk of chronic or fatty liver disease, and a 49% reduced risk of death from chronic liver disease.

Kahweol & cafestol

Ground coffee appeared to be the most effective, with the research team attributing its effect to its high levels of Kahweol and cafestol, which have shown efficacy in chronic liver disease in animals. “There is biological plausibility of a protective effect of coffee against CLD outcomes,”​ the team suggests.

“Alternative active ingredients in coffee may include chlorogenic acid, kahweol and cafestol, which protect against liver fibrosis in animal studies.”

“Kahweol and cafestol are present in highest concentrations in ground coffee, which was most protective,” the paper adds.

“Given the protective effects of the different coffee types with varying composition, there may be a complex relationship involving more than one active ingredient.”

Observational and laboratory studies suggest that consumption of coffee confers a protective effect against chronic liver disease and hepatocellular carcinoma.

This effect has been observed among drinkers of caffeinated and, to a lesser extent, decaffeinated coffee.

Coffee has been proposed as a potential intervention to prevent chronic liver disease onset and progression of hepatocellular carcinoma in at-risk patients.

However, the attributes of an effective coffee-based intervention remain uncertain in terms of quantity and preparation.

This would affect composition since decaffeinated coffee lacks caffeine, while filtered and instant coffee have only minimal amounts of kahweol and cafestol.

No accounting for changes

The team adds that coffee consumption was only reported when participants first enrolled in the study and did not account for any changes in the amount or type of coffee, they consumed over the 10.7-year study period.

As participants were predominantly white and from a higher socio-economic background, the findings may be difficult to generalise to other countries and populations.

Kia ora! Sustainability is at the core of my soul ever since I was a kid. I always strive to finish the food on my plate and live as a minimalist. I love to cut down on waste in order to live sustainably and harmoniously with our planet. This brings me to my passion as a Food Scientist to integrate new technologies into innovative and creative solutions to meet customer demands and market trends and to optimize products and processes for quality, savings and sustainability. To these goals, I have published a Journal on my work on sustainable packaging and patented a new Antimicrobial wash. Nothing is more satisfying than working hard and smart at the workplace and playing hard outside of working hours. I enjoy rejuvenating myself through spending quality time with my two adorable kids and my awesome soul mate and getting close to nature when possible, be it gardening, tramping or going to the beach. I also love to learn about our magnificent universe and how sustainability is working in the grand scheme of things. I strongly believe that Work, Life & Balance is the key to a healthy state of mind, both physically and mentally. I look forward to making a positive difference wherever and whenever I can. Through this Blog, I hope to catalog recent Food Trends and Food Technologies that I come across so that anyone who is interested can have access to it (articles and resources). Please use these resources at your discretion. On top of that, I would also like to share related news and technologies of the future that would help mankind advance towards a Type 1 Civilization. Please feel free to contact me if you would like to share and contribute to the “Resources“. I would like to thank you in advance for dropping by. I sincerely hope that you can benefit from the recent Food Trends and Food Technologies I catalogued. Kind regards | Ngā mihi RenSun Lee
