Evaluation of Select Food Additive Exposures in Children with Crohn’s Disease

Crohn’s Disease (CD) is a chronic, debilitating inflammatory bowel disease and recent research has revealed the possibility that environmental exposures such as diet may play a role in CD etiology and disease activity. Several food additives (e.g. carboxymethylcellulose, carrageenan, maltodextrin) have been shown to cause intestinal inflammation, mucosal barrier alterations, and microbiome dysbiosis in animal…

The Relationship of Diet Quality and Blood Serum Lipid Levels in a Population at High Risk for Diabetes: The Strong Heart Family Study

Blood serum lipid levels are often used as indicators of cardiovascular disease (CVD) risk, while diet quality has an established impact on blood serum lipid levels, including low- and high-density lipoproteins (LDL and HDL) and their corresponding apoproteins, apoB and apoA1 respectively, as well as triglycerides (TGs) and total cholesterol (TC). Diabetes mellitus (DM) is…

Comparison of Objectively and Subjectively Measured Sedentary Behavior in Men with Prostate Cancer and a History of Androgen-Deprivation Therapy Use

Men with prostate cancer commonly receive Androgen Deprivation Therapy (ADT) treatment at some point during treatment. Though efficacious, ADT has significant side effects, including increased risk of cardiovascular disease (CVD) and diabetes. Emerging evidence indicates that reducing sedentary behavior (SB) may reduce the risk of diabetes and CVD. Given the co-morbidities, increased age, and side-effects…

Smarter Lunchroom Evaluations in Snohomish County Promoting Fruit & Vegetable Consumption in Elementary Schools

A majority of students in Snohomish County are not consuming the recommended amounts of fruit and vegetables (F&V). Schools have the ability to influence the amount of F&V consumed by children. Smarter Lunchroom strategies use behavioral economics to persuade students to choose and consume healthy food. Implementing Smarter Lunchroom strategies will support student nutrition and…

Food Shopping Trip Characteristics Before and After the Light Rail

The Seattle Food Action Plan recommends improving healthy food access via non-auto transportation options, and light rail is a public transportation system recently introduced and currently being invested in and expanded. When studying food access, time is both an area-based measure of proximity and a component of travel cost to the individual, but proximity does…

Evaluation of Patient Characteristics, Indications, and Effectiveness of Home Parenteral Nutrition (HPN) Therapy in Obese Adult Patients

Home parenteral nutrition (HPN) involves the administration of parenteral nutrition (PN) therapy outside of the institutional setting. Recipients of HPN are generally patients who do not have acute medical conditions and require long-term nutritional support. The use of HPN has increased in the US. Historically, most patients receiving HPN were underweight or malnourished. However, in…

The sodium potassium ratio: adherence to guidelines in the Multi-Ethnic Study of Atherosclerosis

Few Americans meet the guidelines for sodium and potassium consumption. Yet, sodium reduction remains a major public health aim due to its relationship with hypertension and cardiovascular disease (CVD), increasing potassium is not equally emphasized. The sodium-potassium ratio may better reflect dietary quality with respect to hypertension. Few studies have investigated guideline adherence to a…

Effects of excessive energy intake from fructose- vs. high fructose corn syrup (HFCS)- vs. glucose-sweetened beverages on fasting plasma IGF-1 and IGFBP-3 concentrations

Epidemiological studies indicate that added sugar consumption and plasma concentrations of insulin-like growth factor (IGF-1) are associated with increased cancer risk, particularly for breast and colorectal cancers, but data are less clear for many other cancers (references). Insulin, which stimulates the production and release of IGF-1, is released post-prandially after glucose consumption, but not after…

Association Between Soda Consumption and Body Mass Index in the University of Washington Twin Registry

Obesity is of major public health concern due to its association with many chronic diseases and its history of increased prevalence. Obesity development is influenced by both genetic and environmental factors. This study improves upon previous studies of body mass index and soda consumption by using an informed twin design to decipher how genetic and…
