Offering calories on restaurant websites might be particularly important for consumer meal planning, but the availability of and ease of accessing this information are unknown.
We assessed websites for the top 100 U.S. chain restaurants to determine the availability of and ease of access to calorie information as well as website design characteristics. We also examined potential predictors of calorie availability and ease of access.
Eighty-two percent of restaurants provided calorie information on their websites; 25% presented calories on a mobile-formatted website. On average, calories could be accessed in 2.35±0.99 clicks. About half of sites (51.2%) linked to calorie information via the homepage. Fewer than half had a separate section identifying healthful options (46.3%), or utilized interactive meal planning tools (35.4%). Quick service/fast casual, larger restaurants, and those with less expensive entrées and lower revenue were more likely to make calorie information available. There were no predictors of ease of access.
Calorie information is both available and largely accessible on the websites of America's leading restaurants. It is unclear whether consumer behavior is affected by the variability in the presentation of calorie information.
在餐厅网站上提供卡路里信息对于消费者的用餐计划可能尤为重要，但目前尚不清楚这些信息的提供情况和获取难易程度。
我们评估了美国前 100 家连锁餐厅的网站，以确定卡路里信息的提供情况和获取难易程度，以及网站设计特点。我们还研究了卡路里信息获取难易程度的潜在预测因素。
82%的餐厅在其网站上提供了卡路里信息；25%的餐厅在移动网站上提供了卡路里信息。平均而言，卡路里信息可以通过 2.35±0.99 次点击获取。大约一半的网站（51.2%）通过主页链接到卡路里信息。不到一半的网站（46.3%）有专门的版块来识别健康食品，或者使用互动式的点餐工具（35.4%）。快餐/休闲快餐、规模较大的餐厅、以及提供价格较低的主菜和收入较低的餐厅更有可能提供卡路里信息。目前没有获取难易程度的预测因素。
美国主要餐厅的网站上都提供了卡路里信息，而且这些信息大多易于获取。目前尚不清楚消费者的行为是否会受到卡路里信息呈现方式的差异的影响。
