Correlates Of C-Reactive Protein Levels In Young Adults: A Population-Based Cohort Study Of 3827 Subjects In Brazil, Aydin Nazmi, I. O. Oliveira, Cesar G. Victora

Food Science and Nutrition

The socio-demographic, behavioral and anthropometric correlates of C-reactive protein levels were examined in a representative young adult Brazilian population. The 1982 Pelotas Birth Cohort Study (Brazil) recruited over 99% of births in the city of Pelotas that year (N = 5914). Individuals belonging to the cohort have been prospectively followed up. In 2004-2005, 77.4% of the cohort was traced, members were interviewed and 3827 individuals donated blood. Analyses of the outcome were based on a conceptual model that differentiated confounders from potential mediators. The following independent variables were studied in relation to levels of C-reactive protein in sex-stratified analyses: skin …

Glycemic Load And Risk Of Alzheimer's Disease: The Cache County Study On Memory, Health, And Aging, Eun Young Choi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Carbohydrates are a major energy source for the human body and particularly glucose is the only energy source for the brain. Thus glucose metabolism is important to maintain normal brain function. Evidence showed insulin resistance and diabetes are associated with cognitive decline and a large amount of highly processed carbohydrate intake; in other words, a high glycemic load diet, which increases blood glucose faster and insulin demand, is associated with increased risk of insulin resistance and diabetes.

Based on this premise, the hypothesis that a high glycemic load (GL) diet increases the risk of incident Alzheimer’s disease (AD) was examined …

Department of Nutrition and Health Sciences: Faculty Publications

Nostoc commune var. sphaeroides Kützing (N. commune), a blue-green alga, has been used as both a food ingredient and in medicine for centuries. To determine the effect of N. commune on cholesterol metabolism, N. commune lipid extract was incubated at increasing concentrations (25–100 mg/L) with HepG2 cells, a human hepatoma cell line. The addition of N. commune lipid extract markedly reduced mRNA abundance of 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR) and LDL receptor (LDLR) (P < 0.05), with a concomitant decrease in their protein expression (P < 0.001). Reduced HMGR activity by 90% with N. commune lipid extract confirmed the inhibitory role of N. commune in cholesterol synthesis (P < 0.006). To elucidate a molecular mechanism underlying the repression of HMGR and LDLR by N. commune lipid extract, expression of sterol regulatory …

Enhanced Lipid Stability In Whole Wheat Flour By Lipase Inactivation And Antioxidant Retention, Devin J. Rose, Lynn V. Ogden, Michael L. Dunn, Oscar A. Pike

Faculty Publications

The purpose of this study was to determine the effectiveness of dry heat, steam, and microwave treatments in decreasing lipase activity, while retaining antioxidant activity, to stabilize whole wheat flour against lipid degradation during storage. Bran was heat-treated in 230-g batches using four levels (exposure times) for each of the three treatment methods. Lipase activity and antioxidant activity were quantified for all treatment combinations. None of the treatments significantly decreased antioxidant activity; the levels determined to be optimal, inasmuch as further heating did not significantly decrease lipase activity, were 25 min of dry heat, 60 sec of microwave (1000W), and …

Effect Of Processing Conditions On The Crystallization Behavior And Destabilization Kinetics Of Oil-In-Water Emulsions, Silvana Martini, Megan Tippetts

Nutrition, Dietetics, and Food Sciences Faculty Publications

The objective of this research was to systematically study the effect of processing conditions on the crystallization behavior and destabilization mechanisms of oil-in-water emulsions. The effect of crystallization temperature (T c) and homogenization conditions on both thermal behavior and destabilization mechanisms were analyzed. Results show that the crystallization of lipids present in the emulsions was inhibited when compared with bulk lipids as evidenced by a lower onset and peak temperature (T on and Tp, respectively) in differential scanning calorimetry crystallization exotherms. The smaller the droplet size in the emulsion, the more significant the inhibition (lower T on and T p). …

Loco Labels And Marketing Madness: Improving How Consumers Interpret Information In The American Food Economy, Margaret Sova Mccabe

Law Faculty Scholarship

America's current food labeling scheme, as illustrated by the example of salt, is flawed when examined from the consumer and public health perspective. While the Food, Drug, and Cosmetic Act has sound scientific standards, those standards as currently applied to labels do not efficiently signal health information to consumers. Without better information on labels, consumers will continue to make poor choices at the grocery store. However, there are promising new ways to label. Both the United Kingdom and the domestic supermarket chain Hannaford’s have implemented simple health labeling on food packaging or grocery shelves to improve the amount and location …

Department of Agronomy and Horticulture: Faculty Publications

Biofortification of foods, achieved by increasing the concentrations of minerals such as iron (Fe) and zinc (Zn), is a goal of plant scientists. Understanding genes that influence seed mineral concentration in a model plant such as Arabidopsis could help in the development of nutritionally enhanced crop cultivars. Quantitative trait locus (QTL) mapping for seed concentrations of calcium (Ca), copper (Cu), Fe, potassium (K), magnesium (Mg), manganese (Mn), phosphorus (P), sulfur (S), and Zn was performed using two recombinant inbred line (RIL) populations, Columbia (Col) × Landsberg erecta (Ler) and Cape Verde Islands (Cvi) × Ler, grown …

Effect Of Micronutrient Fortification On Nutritional And Other Properties Of Nixtamal Tortillas, K. E. Burton, Frost M. Steele, Laura K. Jefferies, Oscar A. Pike, Michael L. Dunn

Faculty Publications

Nixtamalization is the process of steeping dried corn in hot water with calcium hydroxide (lime) with subsequent removal of all or most of the pericarp through washing. The resulting product is called nixtamal. Approximately 60% of corn tortillas in Mexico are produced from nixtamal, with the remainder prepared from nixtamalized corn flour. Nixtamal was fortified with micronutrient premix containing iron, zinc, folic acid, niacin, riboflavin, and thiamin. Premix composition followed a proposed Mexican regulation for corn flour fortification, adjusted for moisture. Effects of premix on masa adhesiveness, hardness, and pH, as well as tortilla sensory properties, stretchability, rollability, and color …

Alger, Tam Nguyen, Xuewei Zhu, My-Ngan Duong, Amanda L. Wibley, Ramesh Shah, Matthew A. Davis, Kathryn Kelley, Martha D. Wilson, Carol Kent, John S. Parks, Lawrence L. Rudel

Department of Nutrition and Health Sciences: Faculty Publications

Background—Stearoyl-CoA Desaturase 1 (SCD1) is a well-known enhancer of the metabolic syndrome. The purpose of the present study was to investigate the role of SCD1 in lipoprotein metabolism and atherosclerosis progression.

Methods and Results—Antisense oligonucleotides were used to inhibit SCD1 in a mouse model of hyperlipidemia and atherosclerosis (LDLr^-/-Apob^100/100). In agreement with previous reports, inhibition of SCD1 protected against diet-induced obesity, insulin resistance, and hepatic steatosis. However, unexpectedly SCD1 inhibition strongly promoted aortic atherosclerosis, which could not be reversed by dietary oleate. Further analyses revealed that SCD1 inhibition promoted accumulation of saturated fatty acids …

Total Body Water Estimations In Healthy Men And Women Using Bioimpedance Spectroscopy: A Deuterium Oxide Comparison, Jordan R. Moon, Sarah E. Tobkin, Michael D. Roberts, Vincent J. Dalbo, Chad M. Kerksick, Michael G. Bemben, Joel T. Cramer, Jeffrey R. Stout

Department of Nutrition and Health Sciences: Faculty Publications

Background: Total body water (TBW) estimations have been used to estimate body composition, particularly fat-free mass, to aid in nutritional interventions, and to monitor hydration status. In the past, bioimpedance spectroscopy (BIS) devices have been used to estimate TBW. Previous investigations have examined the validity of the XiTRON 4000B (XiTRON Technologies) BIS device for estimating TBW. Recently, a new BIS device (Imp™ SFB7) has become available, claiming greater precision when estimating TBW. The Imp™ SFB7 (SFB7) is based on similar BIS principles, while offering increased portability and a greater range of frequencies when compared to older devices, such as the …

Poverty, Diet And Health Behaviours: A Quantitative And Qualitative Study Among Young Urbanised Women., Daniel Mccartney

Doctoral

Demographic, socio-economic, attitudinal, dietary, health behavioural and anthropometric data were collected from 221 “disadvantaged” and 74 “advantaged” women aged 18-35 years across Dublin, according to the provisions of a novel socio-economic sampling frame. Internal and external validation techniques established the dietary assessment method of choice and identified “valid” dietary reporters (n=216, 153 disadvantaged, 63 advantaged) among this sample. Five qualitative focus groups (n=5-8 per group) were also conducted among disadvantaged women to examine their diet and health behaviour choices. Lower intakes of fruit and vegetables (172g/d vs. 405g/d, p

Comparison Of Long-Term Care Residents' Food Intake, Body Weight, And Food Costs Between Two Meal Service Styles, Dee Murphy

Master's Theses and Doctoral Dissertations

The purpose of this study was to determine if residents (n = 26) living in an Iowa long-term care facility had differences in food intake at their noon meal and body weight when served traditional tray meal service for 10 weeks compared to being served restaurant-style meal service for 10 weeks. The study also evaluated the facility’s raw food costs of the two meal service styles.

Mean meal intake scale scores improved when residents were served restaurant-style meal service (0.4±0.3) compared to traditional tray meal service. Residents did not show a significant percent weight (1.1%±3.7%) change or percent BMI (0.9%±3.7%) …
