WASHINGTON (AFP) – Researchers in the United States have found another good reason to go to the local espresso bar: several cups of coffee a day could halt the progression of liver disease, a study showed Wednesday.
Sufferers of chronic hepatitis C and advanced liver disease who drank three or more cups of coffee per day slashed their risk of the disease progressing by 53 percent compared to patients who drank no coffee, the study led by Neal Freedman of the US National Cancer Institute (NCI) showed.
For the study, 766 participants enrolled in the Hepatitis C Antiviral Long-Term Treatment against Cirrhosis (HALT-C) trial -- all of whom had hepatitis C which had not responded to treatment with anti-viral drugs -- were asked to report how many cups of coffee they drank every day.
The patients were seen every three months during the 3.8-year study and liver biopsies were taken at 1.5 and 3.5 five years to determine the progression of liver disease.
"We observed an inverse association between coffee intake and liver disease progression," meaning patients who drank three or more cups of java were less likely to see their liver disease worsen than non-drinkers, wrote the authors of the study, which will be published in the November issue of Hepatology.
The researchers put forward several ways in which coffee intake might protect against liver disease, including by reducing the risk of type two diabetes, which has been associated with liver illness; or by reducing inflammation, which is thought to cause fibrosis and cirrhosis of the liver.
Even caffeine, the chemical that gives a cup of coffee its oomph, came under the spotlight, having been found in previous studies to inhibit liver cancer in rats.
But drinking black or green tea, which also contain caffeine, had little impact on the progression of liver disease, although there were few tea drinkers in the study.
According to the World Health Organization (WHO) three to four million people contract hepatitis C each year.
Seventy percent of cases become chronic and can cause cirrhosis or liver cancer.
 
  • In recent decades, more than 19,000 studies have been done examining the impact of coffee. Overall, research has shown that coffee is more helpful than harmful. Some of these studies include the Annals of Internal Medicine research on diabetes and the University of Bristol’s study on cognitive mood.

  • In the November 2008 issue of Oprah's O Magazine in an article called "Small Changes, Big Results" it is reccomended that you drink filtered coffee.  According to the article "A growing body of evidence is linking unfiltered coffee to higher levels of both LDL and total cholesterol."  "Filters can catch surface oils, I learned the hard way that gold filters do very little.  Paper filters are far mor effective." says Nancy Snyderman, MD, cheif medical editor at NBC.

For those who drink four or more cups of caffeinated coffee a day, the risk of developing gallstones was reduced by 45 percent. (The Coffee Science Information Center)
