Mothers' food choices and consumption of ultra-processed foods in the Brazilian Amazon: A grounded theory study
In recent decades, an increase in consumption of ultra-processed foods (UPF), a type of product frequently associated with diet-related obesity, chronic diseases, decrease of eating traditions and loss of culinary diversity, has been observed in middle-income countries. However, there is lack of information on factors related to choosing UPF. In this study, we aimed to understand the factors promoting UPF choices and consumption among mothers living in an urban context in the Brazilian Amazon, and to present a conceptual model grounded on their experiences that illustrates the dynamics between the observed factors. For this qualitative study, we used a constructive grounded theory approach, with a theoretical sampling of 40 women, to choose mothers with high and low consumption of ultra-processed foods. Data production and the first steps of analysis were performed concomitantly, followed by four steps of coding focused on creating conceptual categories and explaining the interactions between them. Our findings highlighted the importance of context in promoting UPF choice and consumption, particularly the âfood environmentâ, physical and virtual, and the âsociocultural environmentâ. These contextual aspects interacted with the two main personal aspects influencing participants' UPF consumption, one concerning practices, âcooking behaviorsâ, and the other concerning preferences, âfood tastesâ. Factors such as economic and time constraints were also important and competed to shape eating practices through interactions with participantsâ health valorization. Findings are discussed in relation to food choice theories, social roles and the food environment. Implications for public health initiatives include the importance of considering environmental changes, sociocultural and economic influences, the reliance on UPF, and the role of women in the home, when promoting healthy diets

An evaluation of the hypolipidemic effect of an extract of Hibiscus Sabdariffa leaves in hyperlipidemic Indians: a double blind, placebo controlled trial
<p>Abstract</p> <p>Background</p> <p>Hibiscus sabdariffa is used regularly in folk medicine to treat various conditions.</p> <p>Methods</p> <p>The study was a double blind, placebo controlled, randomized trial. Sixty subjects with serum LDL values in the range of 130-190 mg/dl and with no history of coronary heart disease were randomized into experimental and placebo groups. The experimental group received 1 gm of the extract for 90 days while the placebo received a similar amount of maltodextrin in addition to dietary and physical activity advice for the control of their blood lipids. Anthropometry, blood biochemistry, dietary and physical activity were assessed at baseline, day 45 and day 90.</p> <p>Results</p> <p>While body weight, serum LDL cholesterol and triglyceride levels decreased in both groups, there were no significant differences between the experimental and placebo group.</p> <p>Conclusions</p> <p>It is likely that the observed effects were as a result of the patients following the standard dietary and physical activity advice. At a dose of 1 gm/day, hibiscus sabdariffa leaf extract did not appear to have a blood lipid lowering effect.</p> <p>Trial Registration</p> <p>REFCTRI2009000472</p
