Using the Twitter Platform as a Research Method in the Information and Social Media Age

Within the context of social media there are rich and massive qualitative sources of data. The intense volume of data produced by social media comprises a promising resource for studying socially constructed language, interactions and behaviours. Research utilising data from social media offers a useful alternative to traditional research methods, which are often restricted and limited by theoretical and methodological boundaries. Social media data are characterised by a qualitative and unstructured nature of using words, either written or spoken, that naturally leads to using a qualitative approach. With social media, researchers immerse themselves with captured social media data as ‘text’. Such involvement poses challenges to researchers, and in particular to identify and locate appropriate data to be collected and develop an appropriate research design that analyses data to its full potential with valid findings. This study contributes methodologically to qualitative research and extends traditional qualitative methods to include the social media platform of designated hashtag of Twitter. Two cases of Organic and Semi-organic Twitter Data are discussed along with research implications and limitations

Considerations for best practices in studies of fiber or other dietary components and the intestinal microbiome

Considerations for best practices in studies of fiber or other dietary components and the intestinal microbiome. Am J Physiol Endocrinol Metab 315: E1087–E1097, 2018. First published August 21, 2018; doi:10.1152/ajpendo.00058.2018.—A 2-day workshop organized by the National Institutes of Health and U.S. Department of Agriculture included 16 presentations focused on the role of diet in alterations of the gastrointestinal microbiome, primarily that of the colon. Although thousands of research projects have been funded by U.S. federal agencies to study the intestinal microbiome of humans and a variety of animal models, only a minority addresses dietary effects, and a small subset is described in sufficient detail to allow reproduction of a study. Whereas there are standards being developed for many aspects of microbiome studies, such as sample collection, nucleic acid extraction, data handling, etc., none has been proposed for the dietary component; thus this workshop focused on the latter specific point. It is important to foster rigor in design and reproducibility of published studies to maintain high quality and enable designs that can be compared in systematic reviews. Speakers addressed the influence of the structure of the fermentable carbohydrate on the microbiota and the variables to consider in design of studies using animals, in vitro models, and human subjects. For all types of studies, strengths and weaknesses of various designs were highlighted, and for human studies, comparisons between controlled feeding and observational designs were discussed. Because of the lack of published, best-diet formulations for specific research questions, the main recommendation is to describe dietary ingredients and treatments in as much detail as possible to allow reproduction by other scientists

Trending Nutrition Controversies #3: Top Controversies in 2021

Each year, patients are bombarded with diverging and even contradictory reports concerning the impact of certain additives, foods, and nutrients on cardiovascular health and its risk factors. Accordingly, this third review of nutrition controversies examines the impact of artificial sweeteners, cacao, soy, plant-based meats, nitrates, and meats from grass compared to grain-fed animals on cardiovascular and other health outcomes with the goal of optimizing clinician-led diet counseling
