In dietary terms, literally nothing is wrong with it. There are economic concerns because the business model is to patent (copyright?) the GMO stuff and force growers to buy seed every year, instead of saving seed from each harvest. There’s also some concern that really successful GMO crops, such as Roundup-ready corn, will dominate planting and become a monocrop which could lead to massive crop loss if a blight or other disease evolves to target that particular strain.

The other things in the picture vary between probably-but-maybe-not-harmless (aspartame), definitely harmless (MSG), to actually helpful (fluoride and Prozac).

Bottom line: the meme, when interpreted correctly, implies that pop songs are generally good but somewhat artificially manipulated.
