New and innovative strategies are needed if we are to significantly increase the mean population intake of fruits and vegetables. To help formulate such strategies as well as to evaluate evidence and identify research gaps, the American Cancer Society and the Centers for Disease Control and Prevention convened the Fruit and Vegetable Environment, Policy, and Pricing Workshop, which brought together experts in how environmental change, policy, and pricing affect fruit and vegetable consumption. The papers in this supplement consist of a review of environmental interventions to improve nutrition and papers covering pricing and consumer value and how fruit and vegetable consumption can be promoted at worksites, restaurants, grocery stores and other community settings, and schools. Conclusions from the workshop were that existing intervention strategies need to be evaluated, promising example programs need to be disseminated, and new innovative interventions and programs need to be created and evaluated.

MyPyramid provides recommendations for fruit and vegetable consumption based on individual calorie requirements as determined by an individual's age, sex, and physical activity level.OBJECTIVES: To determine (1) median fruit and vegetable consumption from all dietary sources among adolescent and adult consumers and the percentage of adolescents and adults meeting individual recommended intake levels based on caloric requirements and (2) consumption levels among various demographic groups, intake levels from subtypes of fruits and vegetables, and primary contributors to fruit and vegetable intake.DESIGN: Analysis of 2-day, 24-hour recall data from the 2003-2004 National Health and Nutrition Examination Survey (NHANES), a continuous, nationally representative, cross-sectional survey.RESULTS: This study included dietary contributions of fruits and vegetables from all dietary sources. Fewer than 1 in 10 Americans meet their calorie-specific MyPyramid fruit or vegetable recommendations. Higher intake was not observed in subgroups with higher recommendations for fruit and vegetable consumption based on caloric requirements. The primary contributors to total fruit intake were whole fruits among adults and fruit juices among adolescents. The largest single contributor to overall fruit intake was orange juice. Potatoes dominated vegetable consumption, particularly among adolescents, in whom fried potatoes increased the median vegetable intake from 0.72 cup to 1.21 cups per day. Dark green and orange vegetables and legumes accounted for a small portion of vegetable intake, and few people met the recommendations.CONCLUSIONS: Few American adolescents or adults reported consuming the recommended amounts of fruits or vegetables. Increasing consumption will probably require multifaceted approaches that augment educational campaigns with policy and environmental strategies aimed at the food system at large, from farm to plate, including schools, worksites, and retail establishments. Increasing America's fruit and vegetable consumption is an important public health strategy for weight management and reduction of risk for chronic disease.

Environmental and policy interventions are more promising for shifting these patterns. We review interventions that influenced the environment through food availability, access, pricing, or information at the point-of-purchase in worksites, universities, grocery stores, and restaurants. Thirty-eight nutrition environmental intervention studies in adult populations, published between 1970 and June 2003, were reviewed and evaluated on quality of intervention design, methods, and description (e.g., sample size, randomization). No policy interventions that met inclusion criteria were found. Many interventions were not thoroughly evaluated or lacked important evaluation information. Direct comparison of studies across settings was not possible, but available data suggest that worksite and university interventions have the most potential for success. Interventions in grocery...

Previous epidemiologic studies have suggested that effects of multivitamins containing substantial amounts of folic acid (introduced in 1973) may not be evident until 15 or more years since first use. We examined the association between daily multivitamin use and colon cancer mortality among 806,397 US men and women in the Cancer Prevention Study II cohort who completed a questionnaire at enrollment in 1982 and were followed for mortality through 1998. After multivariate adjustment, multivitamin use at enrollment showed little association with colon cancer mortality. After 15 years since first use of a multivitamin potentially containing folic acid, we observed slightly decreased risk of colon cancer mortality (rate ratio (RR) = 0.89, 95% confidence interval (CI) 0.80-0.99). Consistent with previous reports, this association was stronger among participants consuming two...

This evaluation addressed two questions: (1) To what extent did children's attitudes toward, familiarity with, and preferences for fruit and vegetables change during the school year? and (2) To what extent did children's consumption of fruit and vegetables change during the school year? During the 2004-2005 school year, the Mississippi Department of Education, Child Nutrition Programs initiated a pilot program to distribute free fruit and vegetables to students (kindergarten through 12th grade) during the school day. Data were collected in 2004-2005 within a one-group pretest/posttest design using a self-report questionnaire (n=725) and 24-hour dietary recalls (n=207) with a sample of students from five schools in Mississippi. Data were analyzed in 2006-2007. Results showed greater familiarity with fruit and vegetables at all grade levels (p<0.05) and increased preferences for fruit ...

School salad bars are an important tool to promote fruit and vegetable consumption among schoolchildren. Studies show that introduction of school salad bars increases the amount and variety of fruits and vegetables consumed by children in schools. However, many schools cannot afford the capital investment in the salad bar equipment. In 2010, the National Fruit & Vegetable Alliance (NFVA), United Fresh Produce Association Foundation, the Food Family Farming Foundation, and Whole Foods Market launched Let’s Move Salad Bars to Schools (LMSB2S) in support of First Lady Michelle Obama’s Let’s Move! initiative.

Although low-energy-dense diets are recommended for weight management, relations between energy density, energy intake, and weight status have not been clearly shown in free-living persons.
