Filter by:The overall aim of the project is to investigate how bowel habits and nutrition in early life relate to the infant gut microbiome and metabolome from birth to 1 year of age. By unravelling links between these factors in early life, we might be able to identify new putative mechanisms by which diet via microbiota-dependent pathways affects intestinal motility in early life. Furtermore, it will be explored how the development of the gut microbiome associates with the child´s development.
Native Americans suffer disproportionately from chronic diseases that may be prevented by achieving a healthy diet, physical activity and weight. For this pilot study, the aim is to examine the effectiveness and feasibility of a standard lifestyle management program implemented in community based settings among Native Americans.
It is estimated that around 20% of breast cancers (BC) in the UK are preventable through adherence to appropriate health behaviours, i.e., healthy diet, physical activity, limited alcohol, not smoking, and that women at increased risk of BC could benefit from greater decreases in risk than the general population via health behaviour changes. Young women (age <35 years) who are at increased risk of developing BC currently receive little or no information regarding health behaviours and BC risk, or support for behaviour change. This feasibility study aims to explore whether a novel app is acceptable to women at increased risk and could potentially engage them with improved health behaviours which could reduce their future risk of BC.
New research suggests that about 1 in 8 children may be diagnosed with an autism spectrum disorder (ASD) in the United States. This could be due to several reasons which remain unknown. This study invites mothers who have given birth to children in the United States to share their experiences with diet and supplementation during pregnancy. The purpose of this study is to understand the role of a mother's diet, social standing, and supplementation with folate or folic acid may have on her child's future development of autism. Comparisons will be made between mothers of children who have a child with an official ASD diagnosis from a clinician to mothers of children without an ASD diagnosis. Findings from this study can be used to help identify risk factors for ASD risk.
Randomized controlled trial of a curriculum intervention teaching patients to eat a whole-food plant-based dietary pattern versus standard of care in kidney transplant recipients within the first few months of transplant
The participant (both mother and child) in the initial TOP study will be invited to a follow-up study to evaluate the effect of life style intervention during pregnancy on both mother and their offspring 12 years after the intervention. The study will contribute to understanding the transfer of obesity between generations and how to treat as well as prevent obesity.
In this study, 18-60 years old patients with metabolic associated fatty liver disease（MAFLD） will be recruited to test the intervention effect of vegetarian diet. This randomized clinical trial randomized individuals to a healthy vegetarian diet or a healthy omnivorous diet for 24 weeks. At the baseline and after the 24week intervention, the clinical manifestations of MAFLD, obesity levels, indices for glucose and lipid metabolism parameters, results of questionnaire and fecal samples will be collected and analyzed.
The purpose of this study is to assess the effects of polyphenols from natural aronia juice on the immune system. Therefore, the study aims to distinguish the effects of natural juices that are rich in phytonutrients such as polyphenols and carotenoids in healthy and depressive subjects in order to use the known positive effects of these food sources in the therapeutic setting. The consumption of natural fruit juices that are rich in polyphenols and carotenoids mirror a model of vegetarian diet due to the increased micronutrient density derived from plant food. Results obtained here can be seen as preliminary explanation models for the beneficial effects of vegetarian diet. It is hypothesized, that the consumption of naturally polyphenol rich aronia juice changes the expression of regulatory T cells, specific cells of the immunesystem that contribute to immunomodulation. Furthermore, beneficial changes in the gut microbiome, the metabolome and the nutritional status are expected in the studied groups. The study was registered retrospectively (after start of recruitment) on Clinicaltrials.gov.
Using a 3-arm randomized controlled trial, the investigators aim to rigorously evaluate the effects of two different taxation policies on diet quality. The first is an implicit sales tax that will be levied only on beverages in a manner that mirrors the current Kingdom of Saudi Arabia (KSA) beverage taxes and the second is an explicit Nutri-Score (NS) based tiered tax that is levied on all food and beverage products. The investigators will use an experimental online grocery store, called NUSMart, which is similar in design to commercial web-based grocery stores to test these two taxation policies. Participants will be randomly assigned to one of the following arms and asked to complete a one-time hypothetical shop. Arm 1 (Control): Participants will experience a default version of NUSMart which replicates the traditional shopping experience of online grocery stores with no FOP labels. Arm 2 (Implicit Tax): Same as Arm 1 NUSMart except that an implicit tax will be levied only on beverages: a 50% sales tax on carbonated drinks and sugar-sweetened beverages (SSBs) and 100% tax on energy drinks (milk, milk-based products, and natural fruit juice are excluded). Arm 3 (Explicit Tiered Tax): Same as Arm 1 NUSMart except that an explicit tiered tax based on (underlying) NS is levied on (sale price of) all food and beverages. NS assesses overall nutritional quality of products on the basis of 7 nutrients (calories, saturated fats, sugar, salt, fiber, protein and percentage of fruits, vegetables and nuts) from A to E (best to worst). In this arm, the investigators implement a 20% sales tax on the retail price for NS D beverages and 10% for NS D foods along with a 50% sales tax on NS E beverages and 20% on NS E foods. The investigators hypothesize the following: Hypothesis 1: Diet quality of food purchases, measured by the weighted average Nutri-Score point, will be highest in the explicit tiered tax arm, followed by the implicit tax arm, followed by the control. Hypothesis 2: Average calories, sugar, sodium, and saturated fat per serving will be lowest in the explicit tiered tax arm, followed by the implicit tax arm, followed by the control.
The present study is a parallel group design with randomised allocation to either a 1) reduced protein diet (RP) or a 2) normal protein diet (NP). The two groups will be pair-matched based on habitual dietary protein intake, endurance training, endurance performance, and sex. The aim of the study is to investigate the effects of reducing dietary protein (~1g protein/kg body mass) compared to an eucaloric normal protein diet (~2g protein/kg body mass) for 6 weeks in well-trained endurance athletes on endurance performance, body composition, skeletal muscle protein synthesis, and health-related outcomes. The hypothesis is that endurance performance will maintain or even be improved in well-trained endurance athletes after a 6-week dietary intervention of an eucaloric, protein reduced diet compared to a normal protein rich diet.
