Consumer Attitudes, Knowledge, And Behavior: Understanding Gluten Avoidance And Point-Of-Decision Prompts To Increase Fiber Consumption, Kristina Arslain

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Understanding consumer food behavior is important for creating effective health programs and policies that address obesity. In this thesis, two topics of consumer food behavior are explored: understanding gluten avoidance and the use of point-of-decision prompts (PDP) to increase the purchase of healthier food choices. In this first topic, nationally representative data was collected on people’s gluten-free (GF) experience and perceptions. It was found that people were more likely to avoid gluten if they believed the (GF) diet was healthier than a gluten-containing diet and if they were recommended to try the diet.

Codonopsis Javanica Root Extracts Attenuate Hyperinsulinemia And Lipid Peroxidation In Fructose-Fed Insulin Resistant Rats, K.-N. Chen, W.-H. Peng, C.-W. Hou, C.-Y. Chen, H.-H. Chen, C.-H. Kuo, M. Korivi

Journal of Food and Drug Analysis

From ancient times, Dǎngshēn (Codonopsis javanica) has been used in Chinese traditional medicine. In this study we investigated the anti-hyperinsulinemia and antioxidant properties of C. javanica root extracts in a rat model of insulin resistance (IR), induced by chronic fructose feeding. Twenty-four Sprague–Dawley rats were randomized into control, fructose-treated (10%, w/v), and fructose then C. javanica (Fru + Cod)-treated groups. After 8 weeks fructose feeding, increased fasting serum insulin levels (2.6 ± 0.45 μg/L) and insulin area under the curve confirmed the IR (p < 0.001). However, C. javanica treatment to fructose-fed rats significantly attenuated the hyperinsulinemia with correspondingly improved glucose tolerance. Weight gain in Fru + Cod group was comparably (p < 0.01) lower than in the fructose-fed group. Furthermore, IR-induced increased hepatic lipid peroxidation, as demonstrated by elevated malondialdehyde levels, were significantly (p < 0.001) alleviated by C. javanica treatment. These findings reveal that chronic fructose intake may facilitate IR and oxidative damage, which could be eradicated by improved antioxidant status. Accordingly, we found that C. javanica treatment significantly improved the antioxidant enzyme activities, including superoxide dismutase, glutathione peroxidase and glutathione reductase in the liver. These findings that fructose-induced hyperinsulinemia and associated oxidative stress could be attenuated by C. javanica root extracts. © 2013
