Wine A 2001 Danish study published in the Archives ofInternal Medicine casts significant doubt on suggestionsthat adults who drink wine have higher levels of “good”cholesterol and fewer heart attacks. These researchersfollowed a group of individuals born at a Copenhagenhospital between 1959 and 1961 for 40 years. Their studyfound that in this group the adults who drank wine werericher and better educated than those who did not.a) What kind of study was this?b) It is generally true that people with high levels ofeducation and high socioeconomic status are healthier than others. How does this call into question the sup-posed health benefits of wine? c) Can studies such as these prove causation (that winehelps prevent heart attacks, that drinking wine makesone richer, that being rich helps prevent heart attacks,etc.)? Explain.
