Background Intake of trans fatty acids (TFAs) increases LDL cholesterol, decreases HDL cholesterol, and increases the risk of heart disease morbidity and mortality. Many food products potentially contain industrially produced or ruminant TFAs. However, little is known about the dietary sources of plasma TFA concentrations. Objective The objective of this study was to examine associations between foods consumed and plasma TFA concentrations using 24-h dietary recall data and plasma TFA measures among adults aged ≥20 y who participated in the NHANES 2009-2010 in the United States. Methods Over 4400 food products in the dietary interview data were categorized into 32 food and beverage groups/subgroups. Four major plasma TFAs (palmitelaidic acid, elaidic acid, vaccenic acid, linolelaidic acid) and the sum of the 4 TFAs (sumTFAs) were analyzed using GC-MS. Multivariable linear regression analyses were conducted to identify associations of plasma TFAs with all 32 food and beverage groups/subgroups, controlling for the potential confounding effects of 11 demographic, socioeconomic, behavioral, lifestyle, and health-related variables. Results Consumption of the following food groups/subgroups was significantly associated with elevated plasma TFA concentrations: cream substitutes (P

Due to changing recommendations for fruit and vegetable (F/V) intake, public health and private organizations recognized the need to revise communications and programs that promote F/V consumption. This article describes formative research conducted in 2005 to develop a new identity for the 5 A Day Program, updated to the Fruits & Veggies—More Matters program. The objective was to re-brand the 5 A Day Program's campaign message to be adaptable, sustainable, and compelling, while leveraging the program's existing message dissemination infrastructure. Formative research included interviews with representatives from government, nonprofit organizations, and industry, and consumer perspectives from interviews, focus groups, and an online survey. Public health and private organizations agreed that a compelling emotional benefit was needed to motivate consumers to eat more F/V and that messaging needed to be used consistently among national, state, and local programs. Interviews and focus groups targeted mothers who believed they and their families were getting enough F/V, knew they could eat more, but needed to be convinced why they should do so. The most effective messages appealed to mothers' emotional needs to be responsible, leveraged functional intrinsic values of F/V, did not try to quantify "enough," and focused on small steps. When the Fruits & Veggies—More Matters slogan and graphic were viewed together, the majority (62%) said it increased their interest in eating more F/V. The Fruits & Veggies—More Matters brand offers numerous opportunities for promoting F/V consumption through this public health initiative.

Objective This study investigated food choices made by individuals consuming diets differing in energy density and explores relationships between energy density and diet quality. Design Cross-sectional, nationally representative survey. Subjects 7,500 adults (older than 19 years) in the 1994-1996 Continuing Survey of Food Intakes by Individuals. Statistical Analysis Energy density values were calculated from reported food intake. Subjects were classified as consuming a low-energy-density diet, medium-energy-density diet, or high-energy-density diet using tertile cutoffs. For each group, the percentage consuming various foods/beverages and the mean amount of foods/beverages they consumed was determined along with mean nutrient intakes. Results Compared with participants consuming a high-energy-density diet, those with a low-energy-density diet had a lower energy intake but consumed more food, by weight, from most food groups. A low-energy-density diet included a relatively high proportion of foods high in micronutrients and water and low in fat, such as fruits and vegetables. Subjects with a low-energy-density diet consumed fewer (nonwater) beverages such as caloric carbonated beverages. They also consumed less fat and had higher intakes of several important micronutrients, including vitamins A, C, and B-6, folate, iron, calcium, and potassium. Conclusions These analyses further demonstrate the beneficial effects of a low-energy-density diet, which was associated with lower energy intakes, higher food intakes, and higher diet quality than a high-energy-density diet. To achieve a low-energy-density diet, individuals should be encouraged to eat a variety of fruits and vegetables as well as low-fat/reduced-fat, nutrient-dense, and/or water-rich grains, dairy products, and meats/meat alternatives.

Dietary energy density [kcal/g (kJ/g)] influences energy intake under controlled laboratory conditions. Little is known about the energy density of the diets of free-living persons. Because energy density investigations are a relatively new endeavor, there are neither standard calculation methods nor published nationally representative values. This paper examines the calculation of energy density based on systematic exclusion of beverage categories, presents data on variability, and compares values by sex, age, and race/ethnicity in a representative sample of U.S. adults. Mean daily dietary energy density values for adults (aged >19 y) were calculated using two 24-h recalls from the Continuing Survey of Food Intakes by Individuals 1994-1996 based on food, food and liquid meal replacements, food and alcohol, food and juice, food and milk, food and juice and milk, food and energy-containing beverages, and food and all beverages. Energy density varied by calculation method, ranging from 0.94 to 1.85 kcal/g (3.93-7.74 kJ/g). Intraindividual-to-interindividual CV ratios were highest for the food and energy-containing beverages calculation. Men reported diets with a higher energy density than women for all calculation methods (P < 0.0001). There were differences by race/ethnicity and an inverse linear trend for age. These data indicate that beverage inclusion schemes should be clearly defined when reporting energy density values. In epidemiologic studies, calculations based on food and all beverages and food and energy-containing beverages may diminish associations with outcome variables. These nationally representative data, which provide an important frame of reference for other studies, indicate that dietary energy density differs by sex, age, and race/ethnicity.

Americans’ consumption of fruits and vegetables has increased slightly over the last 10 years, but most people still do not meet the Dietary Guidelines recommendation to consume 5 to 9 servings per day. 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.
