An apple a day or a Chocolate bar a day?

In this article, there is a new chocolate bar out saying that it is healthy for you to eat two of the bars a day and that it is more healthy for you. The first idea that came to my mind was the competition and substitutes...if people think that the chocolate bars are better than say a granola bar..will the chocolate factory produce more because a good portion of the population loves chocolate and would rather eat something that is healthy and tastes good rather than something that is healthy and does not taste as good? Is there a chance that the chocolate nutrition bar can put granola bars out of business?
