Caffeine Prevents Liver Disease

DC Jeff writes "The Washington Post reports that drinking two cups of coffee or tea daily may reduce the risk of liver disease. From the article: 'The study of nearly 10,000 people showed that those who drank more than two cups of coffee or tea per day developed chronic liver disease at half the rate of those who drank less than one cup each day.'"

This is why pharmaceutical firms use the relative risk (ignoring incidence, just using the percentage) in advertising.

    The incidence of liver disease among non-hepatitis infected people is incredibly small. If you take all comers it is 12th among cause of death (lower than suicde) according to the NIH (pdf of causes of death).

    Because even if the result is statistically significant, if not that many people die of it (~2500 in 2003), then the harm caused by this drug (caffine) may not outway the rare case it saves (and yes, I understand if you're the one it is significant, but this is public health)

    These studies are generally aimed at foods or products that are generally considered to be unhealthy or otherwise, the people making these products are in a defensive position to try and validate their existence.

    The problem is that there are those people just waiting for an excuse to over-indulge in these products. If drinking 2 cups of beer a day prevents cancer, then by drinking 12 I will live to 100, right?

    Often people just read the caption without reading the entire article, or in many cases, the finer points of the study are excluded to a terse clipping of the conclusion without preventing the facts, those facts usually explaining how overindulgence could cause adverse medical problems. This is the case here in Slashdot where many people simply read the blurb without delving into the hyperlinked article.

    Also, these studies are usually contradictory to other studies. Recently it was reported on Slashdot that drinking even one cup of coffee was linked to some kind of adverse health issue. The studies conflict each other, meaning that the truth of the matter is never effectively conveyed by both parties. People that love coffee will be quicker to believe that it is more beneficial to them then those that don't drink it, who would quote coffee is harmful to you.

    Lastely, these studdies generally ignore other serious health issues that might go along with the consumption. Like the fact that most people take cream and sugar in their coffee. Many people in Canada love their double/doubles (2 creams and 2 sugars). This study suggests that drinking two cups of coffee a day has positive health effects, but for those that like cream and sugar in their coffee, this means drinking in addition to the coffee, one will consume 4 servings of high fat cream and 4 teaspoons of suger. The high fat in cream and excessive calories of the sugar are sure to be more harmful to your health then whatever positive effects the coffee may have on your health. Those that feel more is better will consume more high fat cream and high calorie sugars which will exponentially have a negative effect on their health, in addition to ignoring disclaimers by the study that too much coffee could have a detrimental effect.

    Finally, there are those people who consider themselves well learned and so propose that its the caffine in coffee that is beneficial, so drinking a couple cups of cola should also be beneficial, or popping a couple of caffine pills or those high-caf beverages. The study mentions that drinking 2 cups of coffee or tea a day is beneficial, but the Slashdot article only says that Caffeine prevents liver disease, a discrepancy in the facts presented.

    In any case, one should never blindly use these articles as an excuse to continue or start a bad habit. There are MANY healthy ways to prevent Liver Disease, drinking two cups of coffee a days to cure a hangover after consuming an excess of alcohol the previous night probably won't have a positive effect on your liver.
