This advertisement is about 7up soda. We can se that it is promoted as a "family drink" and it shows children in the picture.
This advertisement was published in "Ladies's Home Journal" in 1948.
How is this being dishonest?
As we all know, soda is a drink that can be dangerous for our health due to the sugar and chemicals it contains. We can see that there is no advisement of the dangers of it's consumption. On the contrary, it shows a happy family and shows it as something positive.
Dangers of this kind of advisements
Apart from being a wrong thing in the whole, we can see children in this advisement. This is particularly bad, because the consequences can be much worst in children, since they are in a growing stage. Also, if children have an adiction since and early age, it will be more difficult for them to quit it when they are adults.
Another important point is that "Ladies's Home Journal" was an important american magazine, that was mostly read by women who were housewives. This is clue, because this advertisement could make them think that this beverage is a safe beverage that could be drinked with meals. This could make the drink of sodas a habit.
How can we switch it to be honest?
As this advisement is from 1948, we can't really know if all scientific evidence that shows that the consumption of soda is bad for our health existed by the time. However, we can learn from this. All people view from their own interest for their own benefits. So, before we consume something, we should look for scientific evidence.
