In the version of this article originally published, the organization listed in the ‘Diet and exercise’ row of Table 1 should have been the Centros de Investigación en Red del Instituto de Salud Carlos III, not the European Research Council. In addition, the affiliation shown for Jordi Salas Salvadó (Distinguished Professor of Nutrition at Rovira i Virgili University and Principal Investigator at CIBER-Obn Instituto de Salud Carlos III, Spain) was incomplete. The errors have been corrected in the HTML and PDF versions of the article.
