What may not be used as a claim on a food label?

Food labels cannot use claims that are misleading or false, including unsubstantiated health claims that imply a food can prevent, treat, or cure diseases without scientific evidence. Additionally, claims that are vague or ambiguous, such as "natural" without clear definitions, are typically not allowed. Labels also cannot make comparative claims unless they are backed by data, such as stating one product is "better than" another without proper context or evidence.
