Food provision at the Olympic Games has evolved considerably since the advent of a unified menu, but there are challenges in existing catering for the expanding cultural and sporting diversity. Continuity between events is difficult due to the changes in location, organizing committees, caterers, athletes, support staff, and volunteers. Independent review of the food provision by sports nutrition experts has been implemented to help establish some consistency between Olympic Games. The aim of this study was to compare an expert desk top and onsite review of the food provided at the Rio 2016 Olympic Games, and compare this with a similar review at the London 2012 Olympic Games. A previously developed survey was completed by sports nutrition experts 6 months prior to the opening of the Rio 2016 Olympic village and during the Olympic Games in September 2016. Questions about the food provision included both scaled and open-ended responses. There was a significantly lower rating for menu variety onsite (p = .025) versus the desk top review. All aspects of the menu and the ability to cater for specific situations rated as average or less. A significantly (p = .007) lower overall median rating was obtained for Rio (five out of 10) compared with London (eight out of 10), with hot gluten-free items rated as poor at both events. Comments from experts related to lack of variety, sports and recovery foods, absence of signage, and inaccurate nutrition labeling. An improved process for expert nutrition review at these events is warranted.

2016年里约奥运会的食品供应：专家审查和未来建议。

自统一菜单问世以来，奥运会的食品供应已发生了很大的变化，但是在现有饮食中，为扩大文化和体育多样性提供了挑战。由于地点，组织委员会，宴会，运动员，支持人员和志愿者的变化，事件之间的连续性很难。运动营养专家对食物供应进行了独立审查，以帮助在奥运会之间建立一定的一致性。这项研究的目的是比较专家桌面和对2016年里约奥运会提供的食物的现场评价，并将其与2012年伦敦奥运会上的类似评价进行比较。运动营养专家在2016年里约奥运村开幕前六个月和2016年9月奥运会期间完成了一项先前开发的调查。有关食物供应的问题包括规模化和开放式回应。与桌面审查相比，现场各种菜单的评级明显较低（p = .025）。菜单的各个方面以及满足特定情况的能力（平均或更低）。与伦敦（10个中的8个）相比，里约（10个中的5个）的总体中位数评级显着降低（p = .007），在这两个事件中热无麸质食品均被评为差。专家的评论涉及缺乏品种，运动和恢复食品，没有标牌以及营养标签不正确。
