[We see a shelf. On it, from left to right, are: a bag of fruit gushers; a juicer; a bottle of bright red liquid; a bottle of bright blue liquid; and another bottle of bright red liquid.] "Oh yeah, juicers are great! I use mine all the time."

Juicers are typically used to crush fruits and/or vegetables, thereby extracting the liquid juice and creating a tasty, refreshing and easy to consume drink. However, in this case, instead of actual fruits or vegetables, someone is making juice from Fruit Gushers , a chewy fruit-flavored candy, thereby extracting a nearly nutritionless artificial "juice" out of a candy casing which was formulated specifically for human consumption.
This may or may not be a parody of recent "Fruit Gushers" television commercials, in which Fruit Gushers are shown to squirt out nearly limitless amounts of "juice".
The title text asserts that the rind is where all the vitamins in the fruit reside. This is a common belief of actual fruits, although it is an untrue urban legend for many fruits; even fruits like apples do not contain most of the fiber in the skin itself, but rather directly below; although when you peel an apple you remove more than just the skin, losing also some high fiber content anyway. It is absolutely absurd as in this case, though, as the "rind" of a Fruit Gusher consists mainly of sugar. This text mocks the usual sentiment that the less desirable part of a food is the part that is "better" for you.
It is also a parody of the notion that buying a juicer, or other things like exercise equipment, will automatically make people healthier. Here it is shown that what you do with the juicer is the relevant factor. It is a little hidden joke that there is way more red than blue, pointing out how Gushers (unfairly, because blue is the best flavor) always have more red than blue.
The comic can also be interpreted as parodying the idea of fruit juices being healthy. Though this is widely believed, recent studies demonstrate otherwise.
