“Healthy” Discussions About Risk: The Corn Refiners Association’s Strategic Negotiation of Authority in the Debate Over High Fructose Corn Syrup.
“Healthy” discussions about risk: The Corn Refiners Association’s strategic negotiation of authority in the debate over high fructose corn syrup.

Many foods and eating practices have been framed as risky by risk societies. Recently, high fructose corn syrup (HFCS) has become a highly scrutinized food additive. Informed by a social construction of risk framework, I analyze the discursive contributions of the Corn Refiners Association, a trade association, to public negotiations of HFCS risks. I describe how the association’s Sweet Surprise campaign advertisements rely on a deficit model to shape understandings of who should participate in conversations about HFCS. I conclude by exploring the practical implications of this analysis, particularly how trade associations can negotiate tensions between promoting health and serving commercial interests, and how these decisions contribute to understandings of the public’s role in risk negotiation.

This study aims to investigate: (a) the association of eating disorders with childhood sexual abuse and recent stressful life events; (b) the coexistence of eating disorders and other common psychiatric disorders; and (c) the impact of eating disorders on obesity, medical conditions, and health service utilization.We conducted secondary data analyses based on population-based study, which consists of a nationally representative sample of 2,870 community-dwelling adults aged 50 and above, interviewed in 2006 to 2007.The 12-month prevalence of eating disorders was 2.61%. Multivariate analyses revealed that eating disorders were more common among younger age groups, women, and those who reported stressful life events. In addition, eating disorders were significantly related to anxiety disorders, agoraphobia, panic disorder, obesity, and cancer.This study supports the notion that eating disorders in older adults are associated with a number of psychosocial, psychiatric, and medical conditions.

Postprandial peptide YY is lower in young college-aged women with high dietary cognitive restraint.

Acylated Ghrelin and Peptide YY (PYY3-36) are involved in appetite-regulation and energy homeostasis. These gastrointestinal hormones provide peripheral signals to the central nervous system to regulate appetite and short term food intake, and interact with leptin and insulin to regulate energy balance. Dietary restraint is an eating behavior phenotype manifest as a conscious cognitive control of food intake in order to achieve or sustain a desired body weight. The purpose of the current study was to determine if college-aged women (18 to 25 years) with different eating behavior phenotypes, i.e., high vs normal dietary restraint, differ with respect to circulating concentrations of gastrointestinal hormones during and following a test meal. We hypothesized that women with high dietary cognitive restraint [High CR (score ? 13, n=13)] would have elevated active ghrelin and PYY3-36 concentrations after a test meal compared to women with normal dietary cognitive restraint [Normal CR (score < 13, n=30)]. Gastrointestinal hormones were assessed before (-15 and 0 min) and after (10, 15, 20, 30, 60, 90, 120 and 180 min) the consumption of a mixed composition meal (5.0 kcal per kg/body weight). In contrast to our hypothesis, mean PYY3-36 concentrations (p=0.042), peak PYY3-36 concentrations (p=0.047), and PYY3-36 area under the curve (p=0.035) were lower in the High CR group compared to the Normal CR group after controlling for body mass index. No group differences were observed with respect to acylated ghrelin before or after the meal. In conclusion, PYY3-36 concentrations were suppressed in the women with High CR compared to the women with Normal CR. While the current study is cross-sectional and cause/effect of high dietary restraint and suppressed PYY3-36 concentrations cannot be determined, we speculate that these women with high cognitive restraint may be prone to weight gain or weight re-gain related to the suppressed circulating PYY after a meal. Further investigations need to explore the relationship between dietary cognitive restraint, circulating PYY, and weight gain. HubMed – eating
[Validation of the Eating Attitudes Test as a screening instrument for eating disorders in general population.]

To validate the best cut-off point of the Eating Attitudes Test (EAT-40), Spanish version, for the screening of eating disorders (ED) in the general population.This was a transversal cross-sectional study. The EAT-40 Spanish version was administered to a representative sample of 1.543 students, age range 12 to 21 years, in the Region of Madrid. Six hundred and two participants (probable cases and a random sample of controls) were interviewed.The best diagnostic prediction was obtained with a cut-off point of 21, with sensitivity: 88.2%; specificity: 62.1%; positive predictive value: 17.7%; negative predictive value: 62.1%.Use of a cut-off point of 21 is recommended in epidemiological studies of eating disorders in the Spanish general population.
