Regional Body Composition In College-Aged Caucasians From Anthropometric Measures, Robert T. Davidson, Cameron B. Ritchie

Faculty Publications

Quantitating fat and lean tissue in isolated body regions may be helpful or required in obesity and health-outcomes research. However, current methods of regional body composition measurement require specialized, expensive equipment such as that used in computed tomography or dual energy x-ray absorptiometry (DEXA). Simple body size or circumference measurement relationships to body composition have been developed but are limited to whole-body applications. We investigated relationships between body size measurements and regional body composition. Methods Using DEXA technology we determined the fat and lean tissue composition for six regions of the body in predominantly Caucasian, college-aged men (n = 32) …

Comparison Of A Low Carbohydrate And Low Fat Diet For Weight Maintenance In Overweight Or Obese Adults Enrolled In A Clinical Weight Management Program, James D. Lecheminant, Cheryl A. Gibson, Debra K. Sullivan, Sandra Hall, Rik Washburn, Mary C. Vernon, Chelsea Curry, Elizabeth Stewart, Eric C. Westman, Joseph E. Donnelly

Faculty Publications

Background: Recent evidence suggests that a low carbohydrate (LC) diet may be equally or more effective for short-term weight loss than a traditional low fat (LF) diet; however, less is known about how they compare for weight maintenance. The purpose of this study was to compare body weight (BW) for participants in a clinical weight management program, consuming a LC or LF weight maintenance diet for 6 months following weight loss. Methods: Fifty-five (29 low carbohydrate diet; 26 low fat diet) overweight/obese middle-aged adults completed a 9 month weight management program that included instruction for behavior, physical activity (PA), and …

Glycaemic Index, Glycaemic Load And Ovarian Cancer Risk: A Prospective Cohort, Stephanie A. Navarro Silvera, Meera Jain, Geoffrey R. Howe, Anthony B. Miller, Thomas E. Rohan

Department of Public Health Scholarship and Creative Works

Background

There is some evidence that plasma insulin levels might influence ovarian cancer risk. Glyacemic index (GI) and glycaemic load (GL) are measures that allow the carbohydrate content of individual foods to be classified according to their postprandial glycaemic effects and hence their effects on circulating insulin levels. Therefore, we examined ovarian cancer risk in association with GI and GL, and intake of dietary carbohydrate and sugar. Methods

The study was conducted in a prospective cohort of 49 613 Canadian women enrolled in the National Breast Screening Study (NBSS) who completed a self-administered food-frequency questionnaire (FFQ) between 1980 and 1985. …

Liver Lipid Molecules Induce Pepck-C Gene Transcription And Attenuate Insulin Action., Guoxun Chen

Nutrition Publications and Other Works

Cytosolic phosphoenolpyruvate carboxykinase (PEPCK-C) plays key roles in gluconeogenesis, glyceroneogenesis, and cataplerosis. Experiments were designed to examine the effects of endogenous lipid molecules from rat livers on the expression of PEPCK-C gene in primary rat hepatocytes. The lipid extracts prepared from livers of Zucker fatty, lean, and Wistar rats induced the expression levels of PEPCK-C transcripts. Insulin-mediated reduction of PEPCK-C gene expression was attenuated by the same treatment. The lipid extracts induced the relative luciferase activity of reporter gene constructs that contain a 2.2-kb 5' promoter fragment of PEPCK-C gene, but not the construct that contains only the 3' untranslated …

Walking Age Does Not Explain Term Versus Preterm Difference In Bone Geometry, Haifa Abou Samra, Bonny Specker

Ethel Austin Martin Program Publications

OBJECTIVE: To elucidate the relationship between bone geometry and onset of walking in former term and preterm children.
STUDY DESIGN: We conducted a cross-sectional study of 128 preschool children aged 3 to 5 years who underwent peripheral quantitative computerized tomography measures of bone size at the distal tibia. Linear models were developed, stratifying by sex, to determine whether bone differences between children born term and preterm were caused by differences in walking age.
RESULTS: Children with a history of preterm birth walked later than children born at term (12.4 +/- 0.5 versus 10.9 +/- 0.2 months; P = .004); however, …

Quality Of Hermetically Packaged Split Peas During Long-Term Storage, J. S. Chapman, Laura K. Jefferies, Oscar A. Pike

Faculty Publications

There is a market for low moisture foods that can be stored for long periods of time for use in disaster relief and other emergency situations. Split peas hermetically sealed in cans with a reduced oxygen atmosphere are available in the retail market, but the effect of long-term storage on the quality of the product is unknown. Ten samples of split peas representing 5 retail brands packaged in size No.10 cans and stored at room temperature were obtained from donors. Two fresh samples of split peas were purchased as controls. Samples ranged in age from <1 to 34 years. Can headspace oxygen, can seam integrity, and split pea water activity and color were evaluated. A 52-member consumer panel evaluated the samples, prepared as split pea soup, for appearance, aroma, texture, flavor, and overall acceptability using a 9-point hedonic scale. Acceptance for use in everyday and emergency situations was also determined. Can headspace oxygen ranged from 0.19 to 20.1%. All can seams were determined to be satisfactory. Water activity of the raw split peas ranged from 0.41 to 0.56. The green color of raw split peas decreased over time as shown by increasing CIE a* values. Flavor, appearance, texture, and overall acceptability hedonic scores ranged from 6.7 to 4.4 and decreased over time. Hedonic scores for appearance were correlated with the decrease in raw product green color (r2 = .928). Hedonic scores for texture declined over time, corresponding with increasing hardness of the peas. All samples had an acceptance in an emergency situation of over 75%. Results indicate split pea quality declines over time, but the product maintains sufficient sensory acceptance to be considered for use in applications requiring long-term storage.

Quality Of Hermetically Packaged Dehydrated Carrots During Long-Term Storage, S. R. Bartholomew, Laura K. Jefferies, Oscar A. Pike

Faculty Publications

There is interest in the long-term storage of food for applications such as space flight, disaster relief, and personal preparedness. Dehydrated carrots packaged in hermetically sealed cans with a reduced oxygen atmosphere are available in the retail market. The quality of dehydrated carrots stored up to two years has been reported, but the effect of longer-term storage on the quality of the product is unknown. Eleven samples of dehydrated carrots representing 6 brands, packaged in size No.10 cans and stored at room temperature, were obtained from donors. Two fresh samples were purchased as controls. Samples ranged in age from < 1 to 34 years. Can headspace oxygen, can seam integrity, and dehydrated carrot water activity and color were evaluated. Samples were rehydrated for 20 minutes in filtered water that was brought to a boil. A 56-member consumer panel evaluated the rehydrated carrots for appearance, aroma, texture, flavor, and overall acceptability using a 9-point hedonic scale. Acceptance for use in everyday and emergency situations was also determined. Can headspace oxygen ranged from < 0.01% to 14.7%. All can seams were determined to be satisfactory. Water activity of the dehydrated carrots ranged from 0.31 to 0.38. L*, a* and b* values ranged from 37.8 to 44.0, 17.1 to 30.2 and 23.0 to 37.3, respectively. The orange color of most samples faded during storage. Hedonic scores for overall acceptability of dehydrated carrots declined from 7.1 to 3.4. All samples had an acceptance for use in an emergency situation of over 70%. Results indicate that dehydrated carrots decline in quality during long-term storage but retain sufficient sensory acceptance to be considered for use in long-term storage regimens.

Cholesterol-Lowering Properties Of Plant Sterols Esterified With Beef Tallow Fatty Acids In Hamsters, David M. Guderian Jr., Heather E. Rasmussen, Curtis A. Wray, Patrick Dussault, Timothy P. Carr

Department of Nutrition and Health Sciences: Faculty Publications

Plant sterol esters (PSE) reduce plasma low-density lipoprotein cholesterol concentration by inhibiting cholesterol absorption. Previous work in our laboratory indicated that PSE containing stearic acid (SA), compared to linoleic acid, were significantly more effective at reducing cholesterol absorption. We tested the cholesterol lowering properties of PSE containing fatty acids from beef tallow, a natural and abundant source of SA. Male hamsters were fed diets containing 0.0%, 0.5%, 1.0%, or 5.0% beef tallow PSE for 4 weeks. Dose-dependent reductions (P < .05) were observed in cholesterol absorption, liver esterified cholesterol, and plasma nonhigh-density lipoprotein cholesterol concentration; hamsters fed 5.0% PSE exhibited reductions of 56%, 98%, and 38%, respectively, compared to controls. Concurrent increases (P < .05) in fecal sterol excretion were also observed. In a second hamster study, the cholesterol-lowering properties of beef tallow PSE were compared to hamsters fed molar equivalents of free plant sterols (PS) and free SA. Beef tallow PSE were significantly more effective at reducing liver and plasma cholesterol concentrations than PS and SA consumed individually. Whether PS and SA act through independent or synergistic mechanisms will require further research, although the present findings support the use of dietary PSE containing beef tallow fatty acids in the management of hypercholesterolemia.

Food Science and Nutrition

The fetal origins hypothesis states that nutritional deprivation in utero affects fetal development and contributes to the incidence of diseases associated with the metabolic syndrome in later life. This study investigated whether haemoglobin (Hb) A_1c, an indicator of blood glucose, varied among healthy male adolescents according to their fetal growth rate, in a middle-income setting. Participants were men aged 18 years, belonging to the 1982 Pelotas birth cohort. Complete data, including gestational age and Hb A_1c at age 18 years, were available for 197 individuals. There was an inverse association between mean Hb A_1c and birthweight …

Dietary Fiber Intake And Ovarian Cancer Risk: A Prospective Cohort Study, Stephanie A. Navarro Silvera, Meera Jain, Geoffrey R. Howe, Anthony B. Miller, Thomas E. Rohan

Department of Public Health Scholarship and Creative Works

There is some evidence from case–control studies that dietary fiber intake might be inversely associated with ovarian cancer risk, but there are limited prospective data. Therefore, we examined ovarian cancer risk in association with intake of dietary fiber in a prospective cohort of 49,613 Canadian women enrolled in the National Breast Screening Study (NBSS), who completed a self-administered food frequency questionnaire between 1980 and 1985. Linkages to national mortality and cancer databases yielded data on deaths and cancer incidence, with follow-up ending between 1998 and 2000. Data from the food frequency questionnaire were used to estimate intake of total dietary …

Model-Based Compartmental Analysis Indicates A Reduced Mobilization Of Hepatic Vitamin A During Inflammation In Rats, Sin Gieng, Michael Green, Joanne Green, Francisco Rosales

Faculty Publications

Vitamin A (VA) kinetics was studied in rats with marginal VA stores before, during, and after inflammation. Rats received orally [11,12-3H(N)]retinol ([3H]VA; day 0), and inflammation was induced on day 21 with lipopolysacchride (LPS) for 3 days (n = 5) or recombinant human interleukin-6 (rhIL-6) for 7 days (n = 5). Both the fraction of [3H]VA and retinol concentrations in plasma were reduced significantly by LPS or rhIL-6. Compartmental analysis using the Windows version of Simulation, Analysis, and Modeling software was applied to group mean data, and non-steady-state models were developed. After absorption, VA kinetics was described by a three-compartment …
