Final answer:
Gerber's advertising claim about its formula preventing allergies was an unverified claim, disallowed by the FTC, which monitors truth in advertising to protect consumers.
Step-by-step explanation:
The case of Gerber's claim about its Good Start Gentle formula being able to prevent allergies represents an unverified claim in advertising. The Federal Trade Commission (FTC) enforces rules that prevent untrue factual statements from being advertised to consumers. While some amount of exaggeration can be present, especially when it's about the overall enjoyment of using a product, making an absolute assertion as fact requires that the claim is proven to be true. In the case of Gerber, the FTC's lawsuit and the subsequent settlement in 2019 highlight the importance of only making factual claims that can be substantiated, adhering to the old advice of 'Caveat emptor', meaning 'let the buyer beware.'
