Body Mass Index And Soft Drink Consumption Among Adolescents, Olivia Love Mccord Jul 2004

Body Mass Index And Soft Drink Consumption Among Adolescents, Olivia Love Mccord

Theses and Dissertations

Objective: To determine the relationship between body mass index (BMI) and soft drink consumption among adolescents. It is hypothesized that soft drink consumption contributes to overweight and obesity among adolescents.

Background: Research examining the relationship between body mass index and soft drink consumption is inconsistent. Several studies have found a negative association between total sugar intake and BMI; however, others have found a link between sugar-sweetened drinks and obesity. There are no known studies that have controlled for physical activity.

Data and Methods: Data on approximately 225 adolescents were used. Frequency of soft drink consumption, type of milk, and calcium …


Food Based Approaches For A Healthy Nutrition In Africa, Mamoudou Hama Dicko May 2004

Food Based Approaches For A Healthy Nutrition In Africa, Mamoudou Hama Dicko

Pr. Mamoudou H. DICKO, PhD

The latest estimates of the FAO demonstrate the problems of the fight against hunger. These problems are manifested by the ever-increasing number of chronically undernourished people worldwide. Their numbers during the 1999-2001 period were estimated at about 840 million of which 798 million live in developing countries. Sub-Saharan Africa alone represented 198 million of those. In this part of Africa the prevalence of undernourishment ranges from 5-34%, causing growth retardation and insufficient weight gain among one third of the children under five years of age and resulting in a mortality of 5-15% among these children. Malnutrition resulting from undernourishment is …


Nutrition And Bone Density In Children With Cystic Fibrosis, Joanna K. Davidson May 2004

Nutrition And Bone Density In Children With Cystic Fibrosis, Joanna K. Davidson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of these studies was to further research on bone density in children with cystic fibrosis, particularly as it pertains to nutritional parameters and care. The first paper presented a comparison of a group of 50 children with cystic fibrosis to a group of 32 control children. There were no significant differences between the groups in any of the pertinent bone density measurements. Serum 25(OH) vitamin D was positively correlated with spine density z score in the cystic fibrosis group.

The second paper, incorporating all of the information obtained from the first paper, describes an intervention study with the …


Efficacy Of Different Educational Methods For A High School Prenatal Substance Use Prevention And Nutrition Program., Kimberly Renee Webb May 2004

Efficacy Of Different Educational Methods For A High School Prenatal Substance Use Prevention And Nutrition Program., Kimberly Renee Webb

Electronic Theses and Dissertations

The purpose of this study was to increase knowledge of the effects of prenatal substance use and to introduce the special nutritional needs of pregnancy in two counties in a region with high rates of low birth weight and prenatal substance abuse. A comparison of the efficacy of the educational program being delivered by a registered dietitian or by a group of high school students trained by the dietitian was performed. One hundred six high school students participated in the program and took identical pre- and posttests. The tests were compared to measure knowledge gain and were analyzed by paired …


Phospholipase A2 In Salivary Glands Isolated From Tobacco Hornworms, Manduca Sexta, Hasan Tunaz, David W. Stanley Jan 2004

Phospholipase A2 In Salivary Glands Isolated From Tobacco Hornworms, Manduca Sexta, Hasan Tunaz, David W. Stanley

Department of Entomology: Faculty Publications

We describe a phospholipase A2 (PLA2) associated with the salivary glands of tobacco hornworms, Manduca sexta. This enzyme is able to hydrolyze arachidonic acid from the sn-2 position of PLs. Addition of the calcium chelator, EGTA, or calcium, to the Tris reaction buffer impaired the PLA2 activity, from which we infer the enzyme requires very low concentrations of calcium or perhaps other ions for optimal activity. PLA2 activity was sensitive to protein concentration (highest activity at 25 μg protein per μl), reaction time (optimal at 30 min), buffer pH (optimal at pH 8–10), …


Hortaliza: A Youth "Nutrition" Garden In Southwest Detroit, Kameshwari Pothukuchi Jan 2004

Hortaliza: A Youth "Nutrition" Garden In Southwest Detroit, Kameshwari Pothukuchi

Urban Studies and Planning Faculty Research Publications

This paper documents a youth garden that was developed in 2000 through a university-community partnership in a low-income, predominantly Latino neighborhood in southwest Detroit. It involved four community-based organizations and several residents -- youth among them -- from the neighborhood, in garden planning, set-up, and management. Kids grew vegetables of different kinds to take home and ate healthy snacks at the garden. They learned about the importance of vegetables and fruits to healthy diets, the nutritional value of particular vegetables, and how to grow vegetables. At the end of the season, we documented increased interest among kids in eating fruits …


Nf04-606 Deep Fat Frying Turkeys, Carol J. Plate Jan 2004

Nf04-606 Deep Fat Frying Turkeys, Carol J. Plate

University of Nebraska-Lincoln Extension: Historical Materials

Deep fat frying began in the southern part of the United States and has gradually spread nationwide. Turkeys are the most common food prepared by this method. However, chicken, turkey parts (breasts, wings and thighs), and Cornish game hens may be deep fat fried. Deep fat frying results in a juicy product because the hot fat seals the outside and the skin becomes crisp.

This NebFact talks about the equipment, ingredients, preparation, frying, and safety of deep fat frying turkeys and other poultry.

Diet Quality And Food Limitation Affect The Dynamics Of Body Composition And Digestive Organs In A Migratory Songbird (Zonotrichia Albicollis), Barbara J. Pierce, Scott R. Mcwilliams Jan 2004

Diet Quality And Food Limitation Affect The Dynamics Of Body Composition And Digestive Organs In A Migratory Songbird (Zonotrichia Albicollis), Barbara J. Pierce, Scott R. Mcwilliams

Biology Faculty Publications

Migrating songbirds interrupt their feeding to fly between stopover sites that may vary appreciably in diet quality. We studied the effects of fasting and food restriction on body composition and digestive organs in a migratory songbird and how these effects interacted with diet quality to influence the rate of recovery of nutrient reserves. Food limitation caused whitethroated sparrows to reduce both lean and fat reserves, with about 20% of the decline in lean mass represented by a decline in stomach, small intestine, and liver. During refeeding on diets similar in nutrient composition to either grain or fruit, foodlimited grain-fed birds …


Determination Of The Nutritional Level Of Calcium And Phosphorus In Llamas (Lama Glama) In Two Seasons In The Condoriri Agricultural Experiment Center, Gustavo Adolfo León Titichoca Jan 2004

Determination Of The Nutritional Level Of Calcium And Phosphorus In Llamas (Lama Glama) In Two Seasons In The Condoriri Agricultural Experiment Center, Gustavo Adolfo León Titichoca

Theses and Dissertations

The concentrations of calcium and phosphorus were determined in 12 llamas from the Condoriri Agricultural Experiment Center (Oruro Technical University) of Oruro, Bolivia during two seasons (wet and dry) and at three ages (newborn, juvenile, and adult). Samples of flesh were taken from the arm, leg, back, rib, and neck. Pasture samples (grassland and prairie) were used to determine the rate of biting of each animal studied. The blood samples were taken by extracting blood from a jugular vein. The minerals (Ca and P) in the flesh are highest in the wet season, 113.78 mg/100 g. The newborns were found …
