An Analysis Of The Effects Of A Low Glycemic Diet On The Antisocial Behavior Of Juvenile Offenders, James Edward Longhurst Aug 1987

An Analysis Of The Effects Of A Low Glycemic Diet On The Antisocial Behavior Of Juvenile Offenders, James Edward Longhurst

Dissertations

The objective of this study was to determine if a low glycemic diet contributes to a reduction in the incidence of antisocial behavior among male juvenile offenders.

One hundred forty juvenile offenders at a residential treatment center were randomly divided into treatment and nontreatment groups. The treatment group ate from a diet which contained foods low in glycemic characteristics. There was no dietary alteration for the control group.

Three instruments were used to measure differences between groups in antisocial behavior following a 5-week experimental period. These instruments include: (1) the Unusual Incident Report--a systematic and objective observer report form, (2 ...


Fluoride Content In Home-Canned Fruits In Utah, Sydney Ann Mcdonald May 1987

Fluoride Content In Home-Canned Fruits In Utah, Sydney Ann Mcdonald

All Graduate Theses and Dissertations

The purpose of this research was to determine whether or not canning fruit using fluoridated water made a difference in the fluoride contents of the juice and the pulp. Four cities in Utah were chosen. Two cities were fluoridated (Brigham City and Helper) and two cities were not fluoridated (North Ogden and Price). Three homes were chosen within each city, and three jars of canned fruit (one jar each of apricots, cherries, and peaches) were selected from each home. The fruit samples were freeze-dried, and then the fluoride was measured with a fluoride ion electrode. A difference was found in ...


Effects Of Starter Cultures On Short-To Medium-Chain Free Fatty Acid Content And Sensory Properties Of Mutton Summer Sausage, Robert M. Essiaw-Quayson May 1987

Effects Of Starter Cultures On Short-To Medium-Chain Free Fatty Acid Content And Sensory Properties Of Mutton Summer Sausage, Robert M. Essiaw-Quayson

All Graduate Theses and Dissertations

The effects of starter cultures on short- to medium-chain free fatty acid contents am sensory attributes of different batches of summer sausages were determined. The summer sausages were from range ram mutton, and formulated after grinding to contain 23% fat. Commercial starter cultures from different sources, including Micrococcus varians or Micrococcus species and Lactobacillus plantarum, commercial microbial lipase, an indigenous Micrococcus isolate or encapsulated lactic acid were used to prepare the summer sausages. Three batches were made, each batch receiving six different treatments.

Three consumer panels evaluated the sausages for acceptability and a trained screened panel evaluated the products using ...


Iron Bioavailability Of Meat:Bread Mixtures And Meat Loaves Fed To Anemic And Healthy Rats, Abdullah M. Thannoun May 1987

Iron Bioavailability Of Meat:Bread Mixtures And Meat Loaves Fed To Anemic And Healthy Rats, Abdullah M. Thannoun

All Graduate Theses and Dissertations

To study the effect of meat (beef) on dietary iron bioavailability from enriched white bread (EWB) or whole wheat bread (WWB), diets were prepared in which the ratios of beef iron to bread iron were 100:0, 75:25, 50:50, 25:75 or 0:100. Hemoglobin regeneration efficiency (HRE), apparent iron absorption, and dry matter absorption were determined using weanling anemic and healthy male rats.

Meat iron was more available than EWB or WWB. Fortification iron in EWB was less available than the iron naturally present in WWB. At the iron dose given, HRE was similar for both anemic ...


Effects Of Exercise And Cheese Supplemented Diet On Cholesterol And Lipoprotein Fractions In Free-Living Young Human Subjects, Kathleen A. Gabel May 1987

Effects Of Exercise And Cheese Supplemented Diet On Cholesterol And Lipoprotein Fractions In Free-Living Young Human Subjects, Kathleen A. Gabel

All Graduate Theses and Dissertations

Ten young adults were divided into an exercising group (n = 6) and sedentary group (n = 4). Smoking, ingestion of alcohol, drugs and oral contraceptives were prohibited during 9 weeks of study. Diets were prepared by university food service. Food consumed was recorded and nutrient intakes were assessed. Cheese was consumed in 84 to 112 gram portions every day for two separate 14 day periods. All other dairy products were prohibited in the diet except 240 ml of two percent milk per day. When cheese was consumed, daily diets contained ca 400 kcal, 100 mg cholesterol, and 700 mg calcium more ...


Cholesterol-Lowering Of Pantethine Is Due To The Hydrolysis Product Cysteamine, Caran Graves May 1987

Cholesterol-Lowering Of Pantethine Is Due To The Hydrolysis Product Cysteamine, Caran Graves

All Graduate Theses and Dissertations

Pantethine, a precursor of coenzyme A, has been shown to reduce serum cholesterol levels in hypercholesterolemic rabbits. The enzyme pantetheinase rapidly hydrolyzes pantethine to the vitamin pantothenic acid and the amino thiol cysteamine.

This study was designed to compare the effect of cysteamine and pantothenate supplementation with that of pantethine on hypercholesterolemic rabbits. New Zealand white rabbits were fed a 0.5% cholesterol diet for 5 weeks; treatment groups received only the high cholesterol diet (control), or a high cholesterol diet supplemented with 1% pantethine, or an equimolar amount of pantothenic acid or cystamine (the disulfide of cysteamine). Blood samples ...


Vitamin A Status, Anthropometric Measurements, And Food Practices Of Women Of Childbearing Age And Their Preschool Children In Northeast Brazil, Susan Ahlstrom Henderson May 1987

Vitamin A Status, Anthropometric Measurements, And Food Practices Of Women Of Childbearing Age And Their Preschool Children In Northeast Brazil, Susan Ahlstrom Henderson

All Graduate Theses and Dissertations

Vitamin A nutrition status was evaluated in 110 pairs of women and their preschool children at rural health posts in two different ecological regions of Northeast Brazil. Serum retinol and carotene, weight, height, tricep skinfold and mid-arm circumference were measured from each mother and child. Nutrition knowledge of mothers, socioeconomic living conditions and consumption of retinol and carotene food sources were assessed.

Nine children (8 percent) and one mother had less than acceptable serum retinol (less than 20 μg/dl). Additionally, 21 percent of the children and six percent of the mothers had "low" serum carotene levels. Thirty-seven percent and ...


Adipocyte Glucose Transport Regulation By Eicosanoid Precursors And Inhibitors , He-Chong Cho Lee Jan 1987

Adipocyte Glucose Transport Regulation By Eicosanoid Precursors And Inhibitors , He-Chong Cho Lee

Retrospective Theses and Dissertations

Glucose uptake and free fatty acid release by adipocytes are increased by catecholamines. The mechanism of the stimulatory action of catecholamines on glucose uptake may be via eicosanoid production from release fatty acids. Rats were fed iso-nutrient diets with high (HSO, 20% Kcal of the total Kcal) or low (LSO, 2% Kcal of the total Kcal) safflower oil. After one month, 5 rats per diet group were fed diets with aspirin (ASP group, 50 mg/Kg bw/day) or without aspirin (CON group) for 2 days. Isolated adipocytes from epididymal fat pads were incubated at 37°C, gassed with 95 ...


Effects Of Dietary Beef Tallow And Soy Oil Of Glucose And Cholesterol Homeostasis In Normal And Diabetic Pigs , Laura A. Woollett Jan 1987

Effects Of Dietary Beef Tallow And Soy Oil Of Glucose And Cholesterol Homeostasis In Normal And Diabetic Pigs , Laura A. Woollett

Retrospective Theses and Dissertations

To evaluate whether dietary fats of different degrees of unsaturation alter glucose and very low density lipoprotein-cholesterol (VLDL-CH) homeostasis, normal and alloxan-diabetic pigs were fed diets containing either beef tallow or soy oil as the primary source of fat for 6 weeks. After intra-arterial and oral doses of glucose, pigs fed soy oil had similar glucose and greater insulin concentrations in plasma when compared with pigs fed beef tallow. Beef tallow-fed pigs additionally were 40% more glucose effective than were soy oil-fed pigs. Concentrations of triglyceride, free fatty acid, and gastric inhibitory polypeptide in plasma were measured after consumption of ...
