Consumer advocate: One advertisement that is deceptive, and thus morally wrong, states that gram for gram, the refined sugar used in our chocolate pies is no more fattening than the sugars found in fruits and vegetables   This is like trying to persuade someone that chocolate pies are not fattening by saying that, calorie for calorie, they are no more fattening than celery  True, but it would take a whole shopping cart full of celery to equal a chocolate pie' s worth of calories  Advertiser: This advertisement cannot be called deceptive
It is, after all, true
To make statements that impart only a small proportion of the information in one's possession should not necessarily be regarded as deceptive.
