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) …

Registered Dietitian Dress And The Effect Of Dietitian Dress On Perceived Professionalism, Connie Lynn Packer

Theses and Dissertations

People use others' dress to make assumptions, including how they believe the wearer will behave. Observers then adjust their behavior in response to the anticipated behavior of the wearer. Physician or nurse dress affects the degree to which patients perceive the medical professional as confident, experienced, competent, mature, trustworthy, and professional. Dietitian dress has not been studied. Our purpose was to identify 1) the current level of formality of dress of registered dietitians (RD), 2) characteristics of dress codes, 3) the effect of RD dress on patient/client perceptions of professional traits, and 4) the level of formality at which an …

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 …

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 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.

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.

Combating Childhood Obesity: Changing Our Environment, Anna Mitchell

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

A review of literature was conducted to identify risk factors and prevention strategies for childhood obesity. Factors contributing to childhood obesity include poor food choices, physical inactivity, and genetics. Complications of obesity include respiratory, musculoskeletal, cardiovascular, and endocrine diseases, cancer, gallbladder disease, poor health status, depression, low self-esteem, and social withdrawal. Since childhood obesity, largely due to the environment that children live in today, is increasing in the United States, strategies must be implemented that will contribute to the prevention of childhood obesity. Changes that promote a healthy environment must involve all aspects of society to ensure that the prevention …

The Effect Of Exopolysaccharide-Producing Streptococcus Thermophilus Mr1c On Functionality In High Moisture Cheddar-Type Cheese, Tyler J. Singleton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Differences in texture at any particular stage of ripening depend upon differences in the basic structure and the extent to which the basic structure is modified by physical parameters. Thus, very young cheeses of the same variety differ in texture because of variations in pH and in salt, moisture, and fat content. How well a cheese melts and shreds depend on its texture and physical parameters. Streptococcus thermophilus MR1C produces an exopolysaccharide (EPS) that is tightly associated with the bacterial cell wall. Addition of S. thermophilus MR1C to the cheese make will increase the moisture of the cheese 2-3% …

Phenotypic And Genotypic Analysis Of Amino Acid Metabolism In Lactobacillus Helveticus Cnrz 32, Jason K. Christiansen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study investigated genetic predictions for amino acid biosynthesis and catabolism by Lactobacillus helveticus CNRZ 32, a commercial cheese flavor adjunct that reduces bitterness and intensifies flavor notes. Conversion of amino acids into volatile and nonvolatile flavor compounds by L. helveticus and other lactic acid bacteria in cheese is thought to represent the rate-limiting step in the development of mature cheese flavor and aroma. One of the primary mechanisms for amino acid breakdown by these microbes involves the reversible action of enzymes involved in biosynthetic pathways, so our group investigated the genetics of amino acid biosynthesis in L. helveticus CNRZ …

Texture Profile Analysis And Melting In Relation To Proteolysis As Influenced By Aging Temperature And Cultures In Cheddar Cheese, Taylor Rasmussen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Changes in cheese physical properties during aging are related to proteolysis by coagulant type, culture enzymes, and non-starter lactic acid bacteria (NSLAB). Storage temperature also affects aging rate. Cultures are important for flavor development , but less is understood about their role in melting and textural properties.

Our objective was to make Cheddar cheese using different cultures, to age it at 6 and 13°C, and measure physical and proteolytic properties over 12 mo to determine whether changes in texture and melting correlated with the extent of proteolysis that occurred during aging.

Cheese was manufactured using Lactococcus lactis starter culture either …

Development, Evaluation, And Efficacy Of A Heart Healthy Curriculum In Two Different Education Settings; Emphasizing Food Portioning And Cooking Skills, Increased Fruits, Vegetables, Whole Grains, Low-Fat Dairy, And Exercise, Rachel Richins

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cardiovascular disease (CVD) is a leading cause of mortality and morbidity in the United States. The prevalence of CVD will increase in conjunction with the rise in obesity and type 2 diabetes and decrease in physical activity, due to the adverse effects of adiposity and atherosclerosis associated with these syndromes. Excellent inpatient, outpatient, and community-based program s are available to educate and direct healthy behavioral changes, yet the number of programs available is not sufficient for the volume of patients, nor widely distributed in all areas (particularly rural areas). There is a lack of comprehensive education programs for adults directed …

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.
