Among the concepts which subtend the choice of food the one of ''good'
' and ''bad'' food is one of the most commonly shared. The author show
s that the perception of ''good food'' depends on numerous emotional,
cognitive and sociocultural factors... He then presents the results of
a study on the definition of ''good food'' amongst people suffering f
rom eating disorders who appear to have internalised a mediated social
rule concerning food and make drastic selections thus removing the po
ssibility of choice of foodstuffs. Those who suffer not from eating di
sorders have a carefree, varied and balanced diet. They choose food mo
re freely thanks to less rigid rules and more numerous thought pattern
s. Starting from today's data and theories concerning the mechanisms b
y which food comes to be liked or disliked the author asks questions a
bout the disturbance of such mechanisms among those suffering food dis
orders and about the relevance of cognitive therapy centred on the cog
nitive processes in eating.
