Metabolome response to glycemic load in a randomized, controlled, crossover feeding trial in humans
Observational studies show habitual dietary patterns with low glycemic load (LGL), compared to high glycemic load (HGL), are protective against chronic conditions such as cancer, cardiovascular disease and obesity. The objective of this study was to investigate the metabolomes’ response to glycemic load as measured in plasma and urine. We expected to differentiate between diets…

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…

Obtaining nutritional information for dietary assessment
Accurate dietary assessment is the foundation for determining nutritional status in individuals for clinical practice and in the population for public health. Proper dietary assessment depends on the type of assessment tool used (e.g. food frequency questionnaire (FFQ), food record, etc.) as well as accurate food composition data. The latter factor is less studied and…
