Task: Fact Verification
Input (English): Paragraph: Discussion of costs is relatively unimportant as most individuals would know how much beer costs. The story did quantify the benefits of one parameter by quoting the abstract “incidence of upper respiratory tract infections was 3.25-fold lower” – but it was not mentioned that these were self-reported upper respiratory tract infections. The story mentions that there was ‘significantly less evidence of inflammation….and lower counts of white blood cells than the placebo group” but does not provide numbers. The story also states that the ‘beer experiment’ showed benefits of minimizing post-race damage. But the study didn’t measure damage, it measured blood markers of immune function. In the study, participants consumed 1-1.5 liters/day of non-alcoholic beer (or a placebo) for 5 weeks total. There could be several potential adverse effects such as weight gain from extra calorie consumption, imbalances in nutrients if the liquid replaced other fluids, etc. No potential harms were mentioned. The quality of evidence in the research study was low as it was a non-peer reviewed abstract that was presented at a scientific meeting only, and this is not mentioned. While the treatment (non-alcoholic beer) was compared to a placebo in a double-blinded design, the nature of the placebo is not known, other than that it was a beverage. The research does not mention whether numerous important factors were controlled in the study design (the training regimens of the participants, their diets, their total beverage consumption, etc) and these extensive limitations are not mentioned in the story. No disease mongering. Marathon running was described as “punishing to the body, causing muscle soreness and inflammation.” This is accurate. The story quotes the lead author extensively. Unfortunately, no other independent perspectives are provided. No potential conflicts of interest are noted. The article does not mention potential alternatives that might aid marathon recovery, including any other dietary alterations, and does not discuss the advantages and disadvantages compared with any other approaches. Not applicable. The availability of nonalcoholic beer is not in question. However, it is not clear from the original abstract whether the type of beer matters, as the brand and/or the characteristics (such as calories) were not provided. This is not mentioned in the story. (note: the brand was provided in a press release) The treatment, beer, is not novel, and is not presented as such. Other substances that also contain the purported active ingredient, polyphenols, are discussed. There was an American College of Sports Medicine news release for the abstract, but it doesn’t appear to have been relied upon. Maybe it should have been, since the news release actually includes a disclaimer the story did not include – that the research was presented at a professional meeting but has not been peer-reviewed.
