Overview • Current events • Food • Dietary supplements • Health claims • Food summary • Drugs • History • Key concepts • Labeling • Restricted drugs
Health ClaimsBackground and Policies • Increasing knowledge about food, nutrient and health • Old concept – nutrient, taste, aroma • Opportunities for abuse • Health impacts • Actual harm • Diversion from therapy • Consumer protection • Consumer choice • Personal freedom
Health ClaimsOverview • NLEA – significant scientific agreement • DSHEA – supplement related claims • FDAMA – authoritative statements • Pearson v. Shalala • 2003 Guidance (response to Pearson v. Shalala) • qualified health claims • Less evidence that other bases for health claims • Recent litigation
Key Food Statutes • 343 (q) • Applies to human food • Label must include certain information • Dietary supplements must have certain nutritional information • 343 (r) • Deals with health claims and nutrition claims • Permits claims is there is an “authoritative statement” from US government (sub G) for certain statements • Notice to FDA • Health claims require significant scientific agreement
General Labeling Requirements343(q) • Basic NLEA information (q)(1) (2) • Serving size, nutritional levels, etc. • Exceptions (q) (5) • Restaurants and retail sales • Small business • 343 (r)(5) includes other exceptions
Nutritional Labeling21 USC § 343 (r) • Characterization of food or nutrient value is misbranding unless exception applies • Special rules for cholesterol, fat, etc. • Multiple ways to make health claims • “authoritative statement” • Substantial Scientific Agreement • Pearson type claim • Dietary supplement
Nutritional Labeling21 USC § 343 (r)(2)(G) • Health related claims • authoritative statement by government entity • NAS • NIH • CDC • 120 day prior notification • Challenged by regulation, failure to comply with notification requirements, district court action • Relationship to DSHEA
Authoritative StatementNational Research council • Authoritative statements “are limited to those that represent the consensus of a duly appointed committee or views of a duly appointed principal investigator so that they appear explicitly as findings, conclusions, or recommendations in a report that has completed the institutional report review process” • 1997
Nutritional Labeling21 USC § 343 (r)(2)(G) • Other elements • Identical to authoritative statement • Agency notification of inadequacy • Accuracy (false or misleading?) • Comprehension • Revocation by regulation (343 (r)(2)(H) • See also 21 USC 343 (r) (3) (C)
Nutritional Labeling21 USC § 343 (r)(3) • Health claims based on “significant scientific agreement” • Why agreement and what is it? • Basis of scientific agreement • Qualified experts • Compare to GRASE • Promulgated by regulation • Citizen petitions (21 CFR 10) and (r) (4) • Accurate
Pearson v. Shalala164 F.3d 650 (1999) • Challenge to limitations on health claims • limited or inconclusive data to support health claims • Involves 4 specific health claims rejected by FDA • Dietary supplement provides safe harbor from drug requirements • impact of making drug type claims • FDA regulated health claims for supplements under DSHEA • 1st Amendment challenge
Pearson v. Shalala1st Amendment • Central Hudson 4 part analysis • Not illegal • ,legitimate government interest or policy • advances legitimate government interest and • least burdensome • Government interest • protect health • prevent fraud • Disclosure preferred over suppression • Alternative disclosure mandated • level of scientific support • FDA doesn’t approve use or statements
Pearson v. ShalalaFDA Position • Health claims are inherently misleading • without ‘significant scientific agreement’, statements are inherently misleading • Consumers can’t understand labeling with less than conclusive claims • FDA position viewed as paternalistic • Health claims are potentially misleading • Consumers can’t interpret claims • no access to data • assume FDA agreement with labeling content • Disclaimers inadequate
Pearson v. Shalala1st Amendment • Government interests legitimate • Policy advances anti-fraud interest • Answer is more disclosure, not less • Disclosures adequate • Need to define ‘significant scientific evidence” • Led to 2003 guidance
2003 Guidance • Post Pearson • Broader than statute • Adds more allowable claims • Petition and litigation opportunities • Consumer understanding • Variable impacts • Use of specific language
Health Claims • Qualifying language used to accurately describe strength of claim • Used to allow less proven statements to be made • Category A – established claim • Category B – “evidence is not conclusive” • Category C – “this evidence is limited and not conclusive • Category D – “little scientific evidence supporting this claim”

Dietary Supplements21 USC §343 (s) • Specific misbranding section (343 (s)) • quantity of all ingredients • use of term “dietary supplement” • must conform to specifications in an official compendium • But see Ova II • must meet labeled identity, strength, quality or purity • Not misbranded because of labeled warning or uses • Purpose of this ?
Dietary Supplement Guidance • Extensive comments • Notice and comment process • Good Guidance Practice • 225,000 (many form letters) • Purpose of guidance documents • How binding • Effect of Pearson and Ephedra litigation • Are these relevant?
Dietary Supplement Guidance • Guidelines • Provide useful information to consumers • Scientifically valid support • Do not suggest disease prevention or treatment • “Support” or “maintain” statements allowed if • don’t suggest prevention or treatment • Consumer can evaluate statements • Restorative statements questionable when abnormality implies disease • Avoid NLEA type health claims • Nutritional support claims aren’t drug claims if they avoid reference to specific diseases and don’t make therapeutic promises
