Monday, November 08, 2004The hospital based, case-control study in Milan was based on 507 cases aged 25 to 79 with a first episode of non-fatal acute myocardial infarction and 478 controls admitted for conditions unrelated to heart attack. All those taking part were questioned about their lifestyle, including how much pizza they ate. Pizza eaters were classed as occasional (one to three 200 g portions a month), regular (more than one a week), and frequent (two or more a week). The results show that the greater the consumption of pizza, the lower the risk of heart attack (odds ratio 0.78, occasional eaters; 0.62 regular; and 0.44 frequent) Oh, well, it's one of those retrospective studies which are notoriously bad at predicting causes of illnesses. There could be any number of confounding circumstances besides pizza eating habits that also explain the differences between the groups. These kinds of studies are similar to exit polls - and equally unreliable. So don't give up your fruits and vegetables in favor of Pizza Hut. posted by Sydney on 11/08/2004 07:19:00 AM 0 comments 0 Comments: |
