A diet high in fruits and vegetables is associated with decreased risk for chronic diseases. In addition, because fruits and vegetables have low energy density (i.e., few calories relative to volume), eating them as part of a reduced-calorie diet can be beneficial for weight management. Healthy People 2010 health objectives include increasing to 75% the percentage of persons aged >/=2 years who eat at least two daily servings of fruit (objective 19-5) and increasing to 50% the proportion of persons aged >/=2 years who eat at least three daily servings of vegetables, with at least one third being dark green or orange vegetables (objective 19-6). To assess the level of fruit and vegetable consumption among adults by state and demographic characteristics, data from the 2005 Behavioral Risk Factor Surveillance System (BRFSS) were analyzed. This report describes the results of that analysis, which indicated that 32.6% of adults consumed fruit two or more times per day and 27.2% ate vegetables three or more times per day. The results underscore the need for continued interventions that encourage greater fruit and vegetable consumption among U.S. adults.
富含水果和蔬菜的饮食与降低慢性病风险相关。此外,由于水果和蔬菜的能量密度较低(即相对于体积而言热量较少),将它们作为低热量饮食的一部分食用有助于体重管理。《健康人民2010》的健康目标包括将年龄≥2岁且每天至少食用两份水果的人群比例提高到75%(目标19 - 5),以及将年龄≥2岁且每天至少食用三份蔬菜(其中至少三分之一为深绿色或橙色蔬菜)的人群比例提高到50%(目标19 - 6)。为了按州和人口统计学特征评估成年人的水果和蔬菜消费水平,对2005年行为风险因素监测系统(BRFSS)的数据进行了分析。本报告描述了该分析的结果,结果表明32.6%的成年人每天食用水果两次或更多次,27.2%的成年人每天食用蔬菜三次或更多次。这些结果强调了持续进行干预以鼓励美国成年人增加水果和蔬菜消费量的必要性。
