Editing Ancel Keys (section)

==Criticism==

Keys has received criticism from the [[low-carbohydrate diet]] community, who have argued that his Seven Countries Study excluded countries that did not fit his hypothesis.<ref>{{cite journal |author=Pett, Katherine D |author2=Willett, Walter C |author3=Vartiainen, Erkki |author4=Katz, David L|year=2017|title=The Seven Countries Study|journal= European Heart Journal|url=|volume=38|issue=42|pages=3119–3121|doi=10.1093/eurheartj/ehx603|pmid=29121230|doi-access=free}}</ref><ref name="Pett 2017">{{citation|title=Ancel Keys and the Seven Countries Study: An Evidence-based Response to Revisionist Histories|last1=Pett |first1=K D |last2=Kahn |first2=J |last3= Willett |first3=W C |last4= Katz |first4=DL|year=2017|url=https://www.truehealthinitiative.org/wp-content/uploads/2017/07/SCS-White-Paper.THI_.8-1-17.pdf|publisher=True Health Initiative |access-date=August 29, 2018}}</ref> Critics raised four primary objections to the Seven Countries Study, including (1) countries were selected and excluded based on a desired outcome; (2) France, a high-fat, low-heart disease country, was purposefully excluded from the survey; (3) dietary data in Greece taken during [[Lent]] introduced a distortion; and (4) sugar was not considered as a possible contributor to [[coronary heart disease]]. In response to this criticism, on August 1, 2017, the True Health Initiative released a 65-page white paper entitled "Ancel Keys and the Seven Countries Study: An Evidence-based Response to Revisionist Histories," correcting what they felt were historical inaccuracies and errors that low-carb advocates had perpetuated.<ref name="Pett 2017"/><ref>Pett, Kahn, Willett & Katz (2017) p 22, 32, 37, 43</ref>
