Here’s the silliest health scare of the month:
Study: Eggs Are Nearly as Bad for Your Arteries as Cigarettes
usual the headline is based on science of the fluffiest kind: an
observational study. The sort that doesn’t prove cause and effect.
This egg-study is
even weaker than usual. Instead of trying to make people remember what
they ate last week they actually asked people how many egg yolks they
ate decades ago. Quickly: How many egg yolks did you eat in 1987? Do you
those who ate more whole eggs during the low fat fad also smoked more
etc. So we’re comparing people who ignore health advice with people who
try to be healthy. There are thousands of differences between these two
groups and it’s impossible to control for them all. But the authors of
the study believe that it all comes down to egg yolks.
and nobody who knows how these studies are done take the results too
seriously. But the press loves them. They supply a never ending stream
of juicy headlines.
