What aspect of advertising does the Food and Drug Administration (FDA) regulate?

The Food and Drug Administration (FDA) is primarily responsible for ensuring that food and pharmaceutical advertisements are truthful and not misleading. This regulation is crucial because misleading advertisements can lead to unsafe consumption of drugs or food products. The FDA sets specific guidelines that are designed to protect consumers by requiring that advertisements provide clear information about the benefits, risks, and proper usage of pharmaceuticals, as well as nutritional information about food products. This oversight helps maintain public health standards and ensures that consumers make informed choices regarding their health and nutrition.

In contrast, the other options refer to areas not directly under the FDA's jurisdiction. Influencer disclosures are primarily regulated by the Federal Trade Commission (FTC) to ensure transparency in advertising practices. Political advertising is governed by election laws and regulations, often overseen by the Federal Election Commission (FEC). Environmental claims are typically regulated by the FTC as well, which enforces truth-in-advertising laws to prevent misleading environmental claims in commercial messaging. Thus, the FDA's specific focus on pharmaceuticals and food advertising makes it the correct option.
