Filter by:This study will address the following aims: Aim 1: Conduct an 8-week pilot RCT to examine the effects of a whole foods diet intervention on body adiposity in adolescents with obesity. Aim 1a (Primary): Evaluate intervention effectiveness on total fat mass following the 8-week intervention. Hypothesis 1a: Adolescents randomized to the whole foods intervention will have lower total fat mass (kg) at the 8-week follow-up than those in the control group. Aim 1b: Evaluate intervention effectiveness on anthropometric changes following the 8-week intervention. Hypothesis 1b: Adolescents randomized to the whole foods intervention will have lower weight, BMI-z scores and/or waist circumference at the 8-week follow-up than those in the control group. Secondary Aims: Aim 2: Conduct an 8-week pilot RCT to examine the effects of a whole foods diet intervention on diet quality in adolescent and parent pairs during the study period. Hypothesis 2: Adolescents and parents randomized to the whole foods intervention will have higher diet quality scores at the 8-week follow-up than those in the control group. Aim 3: Conduct post-intervention family focus groups to identify how individual/family needs and preferences and social determinants of health (SDOH) may be perceived barriers and/or facilitators of diet adherence to a whole foods diet pattern.
There is pre-existing evidence that probiotics could be useful in the improvement of ileus rates. One metaanalysis of 30 studies demonstrated a reduction in the prevalence of post-operative ileus as determined by time to flatus, time to defecation, as well as postoperative abdominal distension (PMID:37373843). More broadly in gastrointestinal surgery, a meta-analysis of 21 randomised controlled trials similarly affirmed the speedier recovery of gastrointestinal function after surgery when probiotics were administered (PMID: 35231076). In spite of these advantages, the routine use of probiotics perioperatively for colorectal cancer surgery is not performed in Singapore. We therefore seek to perform a trial to investigate whether probiotic administration perioperatively may reduce post operative ileus rates.
To determine diet-health associations, researchers rely on information obtained from dietary instruments, such as the 24-hour recall (R24H), food frequency questionnaires (FFQ) and food diaries, in clinical studies. However, it is widely recognized that the information provided by the different instruments is biased by different factors including recall errors and respondent burden. The impact of the variability produced by this bias decreases the robustness of diet-health associations which results in the creation of less efficient standards and recommendations for our population. To address this, the discovery of biomarkers of food intake (BFIs) is an objective tool that indicates exposure to specific foods or various dietary patterns. BFIs allow the calibration of dietary information to obtain the real consumption of the individual and thus clarify the relationship between different pathologies of interest and the intake of different foods. BIAMEX will initially focus on the discovery of BFIs of nopal, corn tortilla, mango, avocado, guava and amaranth. For this purpose, a controlled crossover intervention study is being carried out with the 6 foods to be investigated where 24h urine and plasma samples are being collected. Subsequently, the samples collected will be analyzed by mass spectrometry.
Using a two-arm randomized controlled trial (RCT) and an intercept survey, the investigators aim to evaluate the effects of the Multiple-Traffic Light (MTL) front-of-pack (FOP) food labels in Bahrain, on diet quality of grocery shoppers in the Kingdom of Bahrain. The investigators will use an experimental online grocery store, called Bahrain e-Mart, which is similar in design to commercial web-based grocery stores to test these labels. Participants will complete an online shopping experiment on Bahrain e-Mart such that those assigned to the control arm and those assigned to the intervention arm would be exposed to food and beverage products with no FOP labels and with MTL labels, respectively. Participants will randomly be assigned to one of the following arms and asked to complete a one-time shop. Arm 1 (Control): Participants will experience a default version of Bahrain e-Mart which replicates the traditional shopping experience of online grocery stores with no FOP labels. Arm 2 (MTL): Same as Arm 1 Bahrain e-Mart except that Multiple-Traffic Light (MTL) labels are displayed on all food and beverage products. The investigators hypothesize the following: Hypothesis 1: Diet quality, as measured by weighted (by the number of servings) average of all purchased products' Multiple Traffic Light scores for the shopping trip, will be greater in Arm 2 as compared to Control. Multiple Traffic Light is a nutrition labelling system wherein each nutrient attribute constituting this label is assigned different colours according to whether the amount of that nutrient is low (green), medium (amber) or high (red). Hypothesis 2: Diet quality, as measured by weighted (by the number of servings) average of all purchased products' Nutri-Score points for the shopping trip, will be greater in Arm 2 as compared to Control. Relying on the British Food Standard Agency Nutrient Profiling System, the Nutri-Score (NS) point system assigns points to each product based on levels of 7 nutrients (calories, saturated fats, sugar, salt, fibre, protein and percentage of fruits, vegetables, and nuts) per 100g or 100 ml to assess overall nutritional quality. The final NS points range from 0 to 55, with 0 being the least healthy score and 55 the healthiest. Hypothesis 3: The weighted (by the number of servings) average calories (kcal), sugar (g), sodium (mg), total fat (g), and saturated fat (g) per serving will be less in Arm 2 as compared to Control.
The goal of this clinical trial is to learn if increasing adherence to a Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet pattern improves brain and heart health relative to a healthy control diet in middle-aged adults.The main questions it aims to answer are: Does the MIND diet improve cognitive performance and heart health relative to a control diet? Researchers will compare the MIND diet group to a control (a healthy diet that does not match the MIND diet) to see if the MIND provides more benefit to health. Participants will: Consume one meal that follows the MIND diet or a control meal every day for 3 months Visit the lab before and after the 3 months of meals for tests. Keep a record of the food they eat during the study.
Chokeberry can be used both in the prevention and treatment of various metabolic disorders due to its high antioxidant properties. The study assessed for the first time the synergistic effect of chokeberry juice and chokeberry fiber on selected metabolic and anthropometric parameters. 102 people (67 women and 35 men) took part in the intervention study. After 8 weeks of intervention with chokeberry juice and another 4 weeks of intervention with chokeberry juice and fiber, a change in waist circumference, blood pressure, glucose, glycated hemoglobin, LDL cholesterol, aspartate transaminase (AST) and the level of antioxidant potential was observed.
A cross-sectional study representative of the Polish population of children aged 5 months to 6 years conducted in the cross-sectional study model, the main objective of which is to assess the nutritional value of the diet of children aged from 5 months to 6 years with regard to the basic macronutrients: protein (P), fat (F), carbohydrates (C). The study will include: dietary interviews, which will include the Food Frequency Questionnaire questionnaire (FFQ) and a 3-day food diary, as well as anthropometric measurements. The study will involve 1,000 children who will be selected by a random draw based on government database. The survey will be conducted by trained field interviewers - training will be provided by a dietician and an anthropologist. The study also included validation of the FFQ questionnaire.
Meals on Wheels of Rhode Island (MOWRI), in partnership with the University of Connecticut (UConn), will implement and evaluate an enhanced version of its Home-Delivered Meals Program (HDMP). The project goal is to implement and test the effectiveness of an enhanced Home-Delivered Meals (HDM) service delivery approach. The enhanced approach includes community health worker (CHW) interactions and supplemental healthy grocery bags to address diet quality, food and nutrition security, loneliness, and health-related quality of life for older adults. MOWRI participants at the highest nutritional risk will be randomized to receive standard or enhanced services in order to test the effect of the intervention on health-related outcomes. Anticipated outcomes for individuals receiving enhanced services are improvements in measures of diet quality, food and nutrition security, loneliness, and health-related quality of life compared with those receiving standard HDM services.
In the present study the plasma lipid profile was elucidated in healthy, lean males by the use of lipidomic analysis in the hours after an acute intake of medium-chain fatty acids (MCT) and long chain fatty acids (LCT),, respectively. In addition oxygen uptake was measured to study energy turnover.
The goal of this 8-week clinical trial is to learn whether the PortionSize Ed mobile app helps to improve healthy eating habits among early adolescents in the Hawai'i-Food and Lifeskills for Youth (HI-FLY) program. PortionSize Ed is a dietary assessment and nutrition education mobile app, that provides real-time feedback on adherence to tailored dietary recommendations. HI-FLY is a healthy lifestyle program delivered in schools throughout Hawaii. PortionSize Ed also contains educational videos. Participants in this study will be randomly assigned to either the HI-FLY only group (HI-FLY), where they will receive the standard HI-FLY program or to the HI-FLY + PortionSize Ed app (HI-FLY + PSEd) group where they will receive the standard HI-FLY program and a study iPhone with the PortionSize Ed app for the 8-week study. This will allow us to evaluate the effect of the PortionSize Ed app among early adolescents in HI-FLY.
