Correlation Between Nutritional Knowledge And Food Choices In Seventh Grade Students, Jennifer Rysavy

Theses and Graduate Projects

Background Diets of adolescents in the United States are not meeting the Food Pyramid guidelines, especially for fruits, vegetables, and dairy, yet they are far exceeding the recommended daily allowance for fat and added sugars. Even though adolescents possess nutritional knowledge, they are often choosing foods based on their taste, rather than their nutritional value. This study aimed to explore the relationship between nutritional knowledge and food choices in seventh grade students. It also evaluated the relationship gender had on nutrition knowledge and food choices. Method Nutritional knowledge and food choices were studied in two seventh grade health classes at …

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 …

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.

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), …

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 …

The results showed that there has been significant progress since the 1990's in the improved quality of commercially available folic acid products in meeting USP standards.;Products were also tested in physiologically relevant solutions. Most notably, all the tested products failed to release more than 75% of the active ingredient in 60 minutes in simulated …

Inadequate Physician Knowledge Of The Effects Of Diet On Blood Lipids And Lipoproteins., Mary M. Flynn, Chris N. Sciamanna, Kevin C. Vigilante

College of Population Health Faculty Papers

BACKGROUND:To assess the nutrition knowledge of physicians on the basic effects of diet on blood lipids and lipoproteins.

METHODS:Anonymous mailed dietary knowledge surveys to 6000 randomly selected physicians in the United States licensed in either Internal Medicine or Cardiology.RESULTS:Response rate: 16% (n = 639). Half of the physicians did not know that canola oil and 26% did not know olive oil were good sources of monounsaturated fat. Ninety-three percent (84% of cardiologists vs. 96% of internists; p < 0.001) did not know that a low-fat diet, in general, would increase blood triglycerides. Approximately three-quarters (70% of cardiologists vs. 77% of internists; p < 0.01) did not know a low-fat diet would decrease HDL-c and almost half (45%) thought that a low-fat diet would not change HDL-c.

CONCLUSIONS:If physicians are to implement dietary and cholesterol management guidelines, they will likely need to become more knowledgeable about nutrition.
