Background: Consuming a variety (vs. monotony) of energy-poor, nutrient-dense foods may help individuals adhere to
dietary patterns favorably associated with weight control.
Objective: The objective of this study was to examine whether greater healthful food variety quantified using the US
Healthy Food Diversity (HFD) index favorably influenced body adiposity.
Methods: Men and nonpregnant, nonlactating women aged $20 y with two 24-h recalls from the cross-sectional NHANES
2003–2006 (n = 7470) were included in this study. Dietary recalls were merged with the MyPyramid Equivalent database to
generate the US HFD index, which ranges from 0 to ;1, with …

Background: Consuming a wider variety of nutrient-dense foods may promote adherence to healthful dietary patterns, leading to improved dietary quality and enhanced metabolic health.
Objective: We used the US Healthy Food Diversity (HFD) index to simultaneously measure dietary variety, quality, and proportionality, hypothesizing a priori that race/ethnicity may moderate associations between diet and health.
Methods: A representative sample of adults (n = 7470) aged 20+ y with two 24-h recalls and complete outcome data from the cross-sectional NHANES 2003–2006 were selected. US HFD values were generated using a previously validated equation with a theoretical range from 0 …

Maya Vadiveloo
Few longitudinal studies carried out in US adults have evaluated long-term dietary fat intakes and compared them with the national recommendations during the two-decade period when the prevalence of obesity and insulin resistance increased substantively. In the present study, we examined trends in the intakes of dietary fats and rich dietary sources of fats in the Framingham Heart Study Offspring Cohort over a 17-year period. The cohort was established in 1971–75 with follow-up examinations being conducted approximately every 4 years. Dietary data were collected using a semi-quantitative FFQ beginning in 1991 (exam 5). We included 2732 adults aged $25 years …

Maya Vadiveloo
Varied diets are diverse with respect to diet quality, and existing dietary variety indices do not capture this heterogeneity. We developed and evaluated the multidimensional US Healthy Food Diversity (HFD) index, which measures dietary variety, dietary quality and proportionality according to the 2010 Dietary Guidelines for Americans (DGA). In the present study, two 24 h dietary recalls from the 2003–6 National Health and Nutrition Examination Survey (NHANES) were used to estimate the intake of twenty-six food groups and health weights for each food group were informed by the 2010 DGA. The US HFD index can range between 0 (poor) and …

Maya Vadiveloo
Background: Obesity-related dysregulation of the insulin–glucose axis is hypothesized in carcinogenesis.
We studied impaired fasting glucose (IFG) and other markers of insulin–glucose metabolism in the Framingham Heart Study-Offspring Cohort, which uniquely tracks these markers and cancer >37 years.
Methods: Participants were recruited between 1971 and 1975 and followed until 2008 (n ¼ 4,615; mean age
66.8 years in 2008). Serum glucose, insulin, and hemoglobin A1c were determined from fasting blood in quartannual exams. Lifestyle and demographic information was self-reported. HRs and 95% confidence intervals
(CI) of cancer risk were computed using time-dependent survival analysis (SASv9.3), while accounting for …

The Interplay Of Health Claims And Taste Importance On Food Consumption And Self-Reported Satiety.Pdf, Maya Vadiveloo, Vicki Morwitz, Pierre Chandon
Maya Vadiveloo
Research has shown that subtle health claims used by food marketers influence pre-intake expectations,
but no study has examined how they influence individuals’ post-consumption experience of satiety after
a complete meal and how this varies according to the value placed on food taste. In two experiments, we
assess how labeling a pasta salad as ‘‘healthy’’ or ‘‘hearty’’ influences self-reported satiety, consumption
volume, and subsequent consumption of another food. Using MANOVA, Study 1 shows that individuals
who report low taste importance consume less—yet feel just as satiated—when a salad is labeled ‘‘hearty’’
rather than ‘‘healthy.’’ In contrast, for individuals with higher …

Associations Between Dietary Variety And Measures Of Body Adiposity: A Systematic Review Of Epidemiological Studies.Pdf, Maya Vadiveloo, L. Beth Dixon, Niyati Parekh
Maya Vadiveloo
Dietary variety is positively correlated with energy intake in most studies. However, the associations between dietary variety and measures of body adiposity are inconsistent in the literature, which limits the development of clear national nutrition recommendations regarding dietary variety. In the present systematic review, we critically evaluate the associations between dietary variety and measures of body adiposity among healthy adults within the existing literature. We conducted a systematic search of the MEDLINE and Web of Science databases in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement to examine these associations. We identified twenty-six studies in total …

Maya Vadiveloo
Longitudinal associations between leisure-time physical activity (LTPA) and overall cancer mortality were evaluated within the Third National Health and Nutrition Examination Survey (NHANES III; 1988–2006; n = 15,535). Mortality status was ascertained using the National Death Index. Self-reported LTPA was divided into inactive, regular low-to-moderate and vigorous activity. A frequency-weighted metabolic equivalents (METS/week) variable was also computed. Hazard ratios (HRs) and 95% confidence intervals (CI) were calculated for overall cancermortality in the whole sample, by bodymass index categories and insulin resistance
(IR) status. Nonsignificant protective associations were observed for regular low-to-moderate and vigorous activity, and for the highest quartile of …

Consumer Purchasing Patterns In Response To Calorie Labeling Legislation In New York City.Pdf, Maya Vadiveloo, L. Beth Dixon, Brian Elbel
Maya Vadiveloo
Background: Obesity is a major public health threat and policies aimed at curbing this epidemic are emerging.
National calorie labeling legislation is forthcoming and requires rigorous evaluation to examine its impact on
consumers. The purpose of this study was to examine whether point-of-purchase calorie labels in New York City
(NYC) chain restaurants affected food purchasing patterns in a sample of lower income adults in NYC and Newark,NJ.
Methods: This study utilized a difference-in-difference design to survey 1,170 adult patrons of four popular chain
restaurants in NYC and Newark, NJ (which did not introduce labeling) before and after calorie …

PURPOSE: Epidemiologic studies suggest that insulin-like growth factor-1 (IGF-1) is associated with obesity and, more recently, cancer. This study investigates multiple lifestyle, physiologic, and anthropometric determinants of circulating IGF-1 concentrations.
METHODS: Nationally representative data were used from the cross-sectional Third National Health and Nutrition Examination (NHANES III, 1988–1994) survey, which measured IGF-1 concentrations in blood, from a subsample of participants who were examined in the morning. After exclusion of persons with missing data, 6,058 men and women 20 years of age or older were included in the study.
RESULTS: The mean IGF-1 concentrations were 260 ng/mL in …

Childhood provides an opportunity for establishing healthful lifestyle habits, yet little is known about diet
and physical activity patterns of elementary school-aged children. A cohort of 35 boys and girls in grades 3 through 5 (mean age#1;9.5 years) was studied during the course of the 2004-2005 school year, providing seasonal assessments of diet and physical activity. Objectively measured data included height, weight, and pedometer step counts. Subjective data included seasonal 3-day diet diaries, a food frequency questionnaire, and a physical activity questionnaire. Participants were white, well-nourished, and within the healthy range for body mass index for age. Only three students …

Carotenoids, particularly lycopene, are thought to decrease prostate cancer risk, but the relationship between
plasma carotenoid concentrations and risk in various populations has not been well characterized. Comparing 118 non-Hispanic Caucasian men mainly from southeast Texas with nonmetastatic prostate cancer with 52 healthy men from the same area, we conducted a case-control analysis evaluating associations between risk and plasma levels of total carotenoids, β#1;-cryptoxanthin, α- and trans-β-carotene, lutein and zeaxanthin, total lycopenes, trans-lycopene, total cislycopenes, and cis-lycopene isoforms 1, 2, 3, and 5. Risk for men with high plasma levels of α-carotene, trans-β-carotene, β-cryptoxanthin, and lutein and zeaxanthin was less …
