Can School Lunches Deliver Better Nutrition Without Sacrificing Palatability? An Evaluation of Nutritional Adequacy of School Lunches in Urban Washington State
USDA’s National School Lunch Program (NSLP) was established in 1946 to deliver balanced nutrition for children at risk for under-nutrition; however, in recent years these same meals have been associated with over-nutrition and increased risk for childhood obesity. Changes to federal meal standards made in 2013 stand to improve the overall quality and nutritional adequacy...Assessing the Impact of Post-Purchase Barriers on Fruit and Vegetable Consumption: A Secondary Analysis of a Survey of SNAP Recipients at Seattle Farmers Markets
This secondary analysis identifies and describes the impact of self-reported barriers between purchasing produce at farmers markets and consuming that produce at home. This analysis also compares demographic characteristics between participants who did report barriers to fruit and vegetable consumption and those who did not. Finally, we examine differences in self-reported fruit and vegetable shopping...Longitudinal Associations between Home Food Environment and Diet Quality in Children
Child and adolescent diets in the United States are high in fat and sodium and low in vegetables, fruits, whole grains, and dairy foods. Parental practices and foods provided in the home greatly influence children’s food related behaviors. This impact may change as children progress through adolescence and other factors begin to play a role,...August 21, 2014
Differential Effects of Fatty Acids on an In Vitro Model of Hepatocyte Steatosis
Non-alcoholic fatty liver disease (NAFLD) is characterized by excess hepatic fat accumulation in the setting of metabolic syndrome. It ranges from simple hepatic fat accumulation (steatosis), to steatosis with inflammation and fibrosis (steatohepatitis), to end-stage liver disease. Progression of NAFLD has been modeled by a 2 hit hypothesis. The first hit, characterized by triglyceride accumulation,...June 13, 2014
Relationship between socioeconomic status and fruit and vegetable intake among Washington middle school students
School-based programs that provide fruits and vegetables (FV) to low-income children have the potential to reduce disparities in health behaviors and health outcomes. FV are high in fiber and micronutrients. These low-energy dense foods contribute to satiety and satiation; they may be displaced by higher-energy dense but micronutrient-poor foods from the diet such as salty...March 21, 2014
Socioeconomic trends in household food expenditures: Comparing objective food shopping receipts vs. Self-reports
Studies on the association between socioeconomic factors and food purchasing behavior have tended to rely on food expenditure data obtained through participant self-reports. However, self-reported expenditures have only rarely been compared to objective measures such as store and restaurant receipts collected over a given period of time. In addition, few receipt-based studies have addressed the...December 13, 2013
A comparison of the effect of consuming a fructose-, glucose-, or aspartame-sweetened beverage on ad libitum caloric intake
The per capita consumption of sugar-sweetened beverages (SSB) has increased in tandem with the obesity epidemic. While many epidemiological and clinical studies have shown a positive association between consumption of SSB and increased risk of weight gain, the exact mechanism by which the consumption of SSB leads to weight gain remains unclear. The purpose of...Predictors of Responsiveness to Vitamin D Supplementation and Outcomes Assessment in Patients Undergoing Roux-en-Y Gastric Bypass Surgery
Vitamin D is one of the most common micronutrient deficiencies in the obese population awaiting Roux-en-Y gastric bypass (RYGB) surgery and often persists post-operatively despite routinely recommended supplementation, suggesting there may be variable response to this supplementation. However, there are no established indicators that allow clinicians to identify the non-responders, and factors contributing to poor...Plasma 25-hydroxyvitamin D3 response to vitamin D supplementation in obese and non-obese men and women
Obese adults are more susceptible to poor vitamin D status and response to supplementation than lean adults, but explanatory mechanisms remain unclear. Proposed hypotheses include increased degradation or adipose tissue sequestration of vitamin D. The purpose of this study was to investigate how plasma 25-hydroxyvitamin D3 [25(OH)D3] concentrations respond to vitamin D repletion relative to changes...Barriers to WIC Benefits Redemption among Participants in Washington State abstract
The Special Supplemental Nutrition Program for Women, Infants and Children (WIC) is a federal program administered by the states to improve nutritional status through the provision of supplemental food packages, nutrition and breastfeeding education, and referrals to related services. WIC eligibility is based on income and risk (1). Preliminary data for the 2012 Fiscal Year...Previous page Next page
