导致肥胖的因素很多，包括过量摄入“可自由支配的卡路里”(高糖分、高脂肪、低必需营养素的食物)、缺乏水果/蔬菜，以及体力活动不足。这项研究对比了选定食物的体力活动、水果/蔬菜和可自由支配的卡路里摄入量与2005年饮食指南的对比。我们在洛杉矶县和路易斯安那州南部的228个城市人口普查区域进行了一项横断面调查，估计了2767名参与者在过去24小时内从水果、蔬菜、饼干、糖果、咸味零食、加糖苏打水和酒精中获得的卡路里。按人口加权平均每天从糖果、饼干、咸味零食、苏打水和酒精中摄取的卡路里，洛杉矶县为438卡路里，路易斯安那州为617卡路里。酒精在所消耗的卡路里中只占一小部分。据报道，在洛杉矶和路易斯安那州，一小部分食物的可自由支配卡路里消耗量超过了指导方针的60%和120%。相比之下，洛杉矶和路易斯安那州的水果和蔬菜平均消费量分别少了10%和20%。饼干、糖果、咸味零食和苏打水的消费在收入、性别和种族方面都存在显著的异质性。可自由支配卡路里的过量摄入量远远大于水果和蔬菜的摄入量不足，这表明，除非盐味零食、饼干、糖果和含糖饮料的过度摄取得到遏制，否则其他侧重于增加体力活动和水果蔬菜摄入量的干预措施对控制肥胖的影响有限。在政治上，推动加息可能比减税更有利，但效果可能要差得多。
There are many contributors to obesity, including excess consumption of “discretionary calories,” (foods high in sugar and fat and low in essential nutrients), lack of fruit/vegetable consumption, and insufficient physical activity. This study contrasts physical activity, fruit/vegetable, and discretionary calorie consumption from selected foods relative to the 2005 dietary guidelines. We conducted a cross-sectional survey in 228 urban census tracts in Los Angeles County and Southern Louisiana and estimated calories in the past 24 hours from fruits, vegetables, cookies, candy, salty snacks, sweetened soda, and alcohol among 2,767 participants. The population-weighted average daily intake of calories from candy, cookies, salty snacks, soda, and alcohol was 438 in Los Angeles County and 617 in Louisiana. Alcohol comprised a small portion of the calories consumed. Reported discretionary calorie consumption from a small set of items exceeded guidelines by over 60% in Los Angeles and by 120% in Louisiana. In contrast, the average consumption of fruit and vegetables falls 10% short in Los Angeles and 20% in Louisiana. There is significant heterogeneity in cookies, candy, salty snacks and soda consumption across income, gender, and race. The overconsumption of discretionary calories is much larger than the under-consumption of fruits and vegetables, suggesting that unless the excessive consumption of salty snacks, cookies, candy and sugar-sweetened beverages is curtailed, other interventions focusing on increasing physical activity and fruit and vegetable consumption will have a limited impact on obesity control. It may be politically more expedient to promote an increase than a decrease, but it may be far less effective.
