Health claim
Template:Short description Template:About
A health claim on a food label and in food marketing is a claim by a manufacturer of food products that their food will reduce the risk of developing a disease or condition.<ref>Template:Cite web</ref> For example, it is claimed by the manufacturers of oat cereals that oat bran can reduce cholesterol, which will lower the chances of developing serious heart conditions. Vague health claims include that the food inside is "healthy," "organic," "low fat," "non-GMO," "no sugar added," or "natural".
Health claims are also made for over-the-counter drugs and prescription drugs, medical procedures, and medical devices, but these generally have a separate, much more stringent set of regulations.
Health claims in the United States
In the United States, health claims on nutrition facts labels are regulated by the U.S. Food and Drug Administration (FDA), while advertising is regulated by the Federal Trade Commission.<ref>Template:Cite web</ref> Dietary supplements are regulated as a separate type of consumer item from food or over-the-counter drugs.Template:Cn

FDA guidelines
According to the FDA, "Authorized health claims in food labeling are claims that have been reviewed by FDA and are allowed on food products or dietary supplements to show that a food or food component may reduce the risk of a disease or a health-related condition."<ref name="FDA">Template:Cite web</ref><ref name="fda-q&a">Template:Cite web</ref> An authorized health claim is limited to evidence for reducing the risk of a disease, and does not apply to the diagnosis, cure, mitigation, or treatment of disease.<ref name=fda-q&a/> It must be reviewed, evaluated, and publicly-announced by the FDA prior to use.<ref name=fda-q&a/>
Approval of a health claim by the FDA requires significant scientific agreement (SSA) among reputable scientists that the claim is based on publicly-available evidence that a relationship exists between an element and a disease.<ref name=FDA/><ref name=fda-q&a/> The SSA standard provides a high degree of confidence that the relationship between the element and the disease is valid.<ref name=FDA/>
Based on scientific evidence, such claims may be used for marketing on foods or dietary supplements.<ref name=FDA/> The authorized health claim must be written in a way that helps consumers understand the importance of including the element in their daily diet.<ref name=FDA/>
The FDA has guidelines for what is considered a misleading label,<ref name=":4">Template:Cite web</ref> and also monitors and warns food manufacturers against labeling foods as having specific health effects when no evidence exists to support such statements, such as for one manufacturer in 2018.<ref>Template:Cite web</ref>
A qualified health claim is supported by some scientific evidence, but does not meet the significant scientific standard of evidence required for an authorized health claim. Qualified health claims must be accompanied by a disclaimer or other qualifying language to accurately communicate the level of scientific evidence supporting the claim.<ref name="fda-qhc">Template:Cite web</ref>
Consumer advocacy
The use of the label “Healthy” on a variety of foods has been a particular issue for many food quality advocacy groups. In general, claims of health benefits for specific foodstuffs are not supported by scientific evidence and are not evaluated by national regulatory agencies. Additionally, research funded by manufacturers or marketers has been criticized to result in more favorable results than those from independently funded research.<ref name="Slop">Template:Cite journal Template:Open access</ref>
Dietary supplements
In the United States, these claims, usually referred to as "qualified health claims", are regulated by the Food and Drug Administration (FDA) in the public interest.<ref>Template:Cite web</ref>
The rule in place before 2003 required "significant scientific consensus" before a claim could be made, applying characterization of a hierarchy of degrees of certainty:
- A: "There is significant scientific agreement for [the claim]."
- B: "Although there is some scientific evidence supporting [the claim], the evidence is not conclusive."
- C: "Some scientific evidence suggests [the claim]. However, the FDA has determined that this evidence is limited and not conclusive."
- D: "Very limited and preliminary scientific research suggests [the claim]. The FDA concludes that there is little scientific evidence supporting this claim."
See the Wikipedia article on dietary supplements for a description of current FDA policy.

Health claims in Europe
In the European Union, the European Food Safety Authority provides regulations on food labeling to address the quality of possible health foods.<ref>Template:Cite web</ref>
In the United Kingdom by law any health claim on food labels must be true and not misleading. Food producers may optionally use the (discontinued in 2010) Joint Health Claims Initiative to determine whether their claims are likely to be legally sustainable.Template:Cn
In early 2005 the European PASSCLAIM project (Process for the Assessment of Scientific Support for Claims on Foods), sponsored by the European Union and coordinated by ILSI-Europe (https://web.archive.org/web/20090822045739/http://europe.ilsi.org/), ended. The aim of this project was to develop criteria for the scientific substantiation of claims on foods. Several hundreds of scientists from academia, research institutes, government and industry have contributed to the project. All the resulting papers can be downloaded for free from http://www.ilsi.org/Europe/Pages/PASSCLAIM_Pubs.aspx. The final consensus paper, comprising the final set of criteria, has been published in June 2005 in the European Journal of Nutrition.<ref>Template:Cite journal</ref>
