In this advertisement, the creator has used several different lines of logical all of which are valid. However, sometimes the advertisement exaggerates a premise, so it is not always true.
All healthy food is good for you
Bananas are healthy
Therefore they are good for you.
This is valid and true.
All junk food kills you
Healthy food does not kill you
Therefore, healthy food is not junk food
It is valid, but not entirely true. It exaggerates how bad junk food is, it in it self does not kill.
All junk food kills you
Bananas are not kill you
Therefore, bananas are not junk food
It is valid, but not really true. Again, junk food does not directly kill you.
The advertisement assumes, firstly that bananas are healthy, and good for you. It assumes that the viewer does not eat healthy food, and eat junk food. The major assumption it makes, where the premises becomes slightly exaggerated, is that junk food “kills you”, meaning that it is detrimental to your health, and that healthy food (especially bananas) is not.

This advertisement uses the usual assumption that most people hold, is that apples are healthy and good for you, and that we should eat it in order to remain healthy.
