Filter by:The investigators propose to assess the effects of including mushrooms as part of a healthy eating pattern on indices of perceived mental health/anxiety/depression, along with risk factors for cardiovascular disease and type 2 diabetes.
The investigators propose to determine the effect of consuming 0, 1 or 2 servings of white button (Agaricus bisporus; most popular, lower ergothioneine) or yellow oyster (Pleurotus citrinopileatus; higher ergothioneine) mushrooms on postprandial changes in plasma levels and urinary excretions of mushroom-specific compounds.
The prevalence of adolescent behaviors that can lead to obesity are alarming, and reduced life expectancy is the future of America's youth if behavioral changes are not implemented to improve health and reduce the obesity burden. Researchers have argued that health literacy is a precursor to health knowledge and is necessary for translating knowledge about healthy choices into behavior, with low health literacy being associated with reduced preventive health behaviors in adults. Given the lack of health literacy-specific interventions addressing adolescents' obesogenic behaviors, the purpose of this study is to examine the preliminary effectiveness of adding a health literacy module to an obesity prevention intervention that addresses adolescents' obesogenic behaviors.
The study will compare achieved levels of protein-bound uremic toxins with dialysis using a medium cut-off membrane compared to the treatment by online haemodiafiltration with a high-flux dialysis membrane. In the second phase of the study dietary fiber and short-chain fatty acid intake will be increased to verify a possible additional reduction in the levels of protein bound uremic toxins.
Patients with RA will be studied to see whether meals of different content will affect inflammation and metabolic variables in the postprandial state. Healthy controls will also be invited to examine potentially different responses to patients with RA.
This study used a two-group pre-posttest experimental design. After completing a background survey, participants used their smartphones to uploaded photos and/or descriptions of their meals to an online platform for three days. In addition, those in the intervention group were asked to use a checklist to count the number of times they ate red/orange vegetables and to set a goal to eat one more time the next day. The dependent variable was a measure of eating behavior—an estimate (number of times/day) of red/orange vegetable intake on that day based on review of uploaded photos and descriptions. Those in the intervention group, who were asked to use a checklist to count their red/orange vegetable intake and set a goal to eat one more the next day, improved their vegetable intake.
There is a need to develop evidence-based interventions that rural food pantries can use to limit the distribution and intake of ultra-processed foods and promote the distribution and intake of minimally processed foods in the food environment and among low-income populations to promote better dietary quality and health outcomes. This research project, The UnProcessed Pantry Project (UP3): A Novel Approach to Improving Dietary Quality for Low-Income Adults Served by Rural Food Pantries, uses the Social-Ecological Model to target multiple levels, including the food supply in the rural study location (community level), the food environment at the food pantry (environmental level), and participant dietary intake (individual level). Aim 1 will adapt evidence-based strategies to inform UP3. UP3 will improve dietary quality by influencing the food supply through organization-wide nutrition policies, modifying the food environment with minimally processed foods and nudges, and changing participant dietary intake through experiential nutrition education. The UP3 pilot study will be conducted during Aim 2 with 40 participants served by two rural food pantries in Montana. The purpose of the pilot study is to investigate potential short-term effects on nutrient intake and dietary quality (primary outcome), assess acceptability of UP3 among participants, and evaluate feasibility in rural food pantry environments. It is hypothesized that UP3 will improve access to minimally processed foods and decrease access to ultra-processed foods at the food pantry, which will improve overall dietary quality of individuals as measured by the Healthy Eating Index-2015 compared to baseline and to the control group. Demographic and food security data will characterize the population. Psychosocial factors will be collected to understand changes in knowledge, attitudes, and perceptions about processed foods. Biomarkers of health data (i.e., weight, systolic blood pressure, HbA1c, fasting lipid panel) will be collected to determine the feasibility of measuring potential short-term health effects alongside UP3. A control group of 20 participants at a rural food pantry will be used to assess dietary intake, psychosocial factors, height, and weight. Aim 3 will tailor UP3 for a scalable intervention suited for an R01 grant application to conduct a randomized controlled trial (RCT). UP3 is positioned to demonstrate the positive effects of limiting processed foods and increasing unprocessed and minimally processed foods on diets and, potentially, health among low-income populations. The short-term goals of this research are to develop an adaptable and scalable intervention suitable for rural food pantries serving low-income populations, as well as potentially contribute to a knowledge base around potential short-term effects of the minimally processed foods diet on dietary quality and health risks in those populations. The longer-term goals are to test the efficacy of the intervention in an RCT and then disseminate the approach to be integrated into rural food pantries serving low-income populations with the goal of decreasing health risks.
Previous adult participants of the Tanglewood to Table walking program will be recruited to enroll in the CANE Meal Program. This program will encourage participants to pick up a healthy meal from the CANE Kitchen each week for five weeks. The meal will consist of at least one serving of fruit or vegetables. At each meal, educational materials will be distributed, including the recipe for healthy meals and nutrition handouts that are linked to the recipes. Additional information about the ways the nutrients in the meal may help protect from the negative effects of environmental pollutants will be included. Surveys, blood pressure, height, weight, waist circumference and carotenoid status will be assessed before and after the program.
Poor diets are known risk factors for chronic diseases, and in recent years, food labelling has been increasingly sought-after as a cost-effective intervention to help stem the rising trend in chronic diseases. In efforts to promote a healthy diet, the Singapore Health Promotion Board (HPB) supplements traditional nutrition labelling with the Healthier Choice Symbol (HCS), which identifies food items within a specific category of foods as healthier choices. The original logos were enhanced to include additional information focusing on particular macronutrients, taking one of two themes; it either indicates that a product contains more of a healthier ingredient, or less of a less healthy ingredient. However, to date, no published studies have assessed the role of the original and enhanced HCS logos in influencing food choices. There is a lack of scientific evidence on the role of the existing symbols in assisting consumers make healthier food purchasing decisions. There are also concerns over the unintended consequences of health claims made based on a single aspect of nutrient content, without considering other aspects. That is the goal of this effort. Specifically, the investigators propose to conduct the following: Use a three arm randomized controlled trial (RCT) and an experimental fully functional web-based grocery store to assess the causal effect of the new HCS logos on measures of diet quality either alone, or in combination with a complementary front-of-package (FOP) label: Physical Activity Equivalents (PAEs), which provides information on how long one would need to engage in a certain activity (e.g., jogging) to burn off one serving of the product. The investigators hypothesize that the greatest reduction in calories per serving (primary outcome) will occur in the HCS plus PAEs arm, followed by HCS only, and no logo control arm.
This study will develop a digital intervention ("Healthy Roots") adapted from a previously tested adult digital obesity treatment intervention ("Track").
