Filter by:This study aimed to investigate the effect of different doses of hydrolyzed collagen (HC) with resistance exercise (RE) on whole body collagen synthesis in healthy young and older males and females.
This project is a research study looking at what foods students choose and eat during school lunch and examines how salad bars impact what children eat.
The objective of this research was to determine if adding a plate graphic depicting the components of the Eat Lancet Planetary Health diet (Figure 1) to food labels in Stanford University dining halls would lead to dining hall patrons making dietary decisions that better resemble the Planetary Health diet in comparison to a no signage control group. The study hypothesis was that presenting students with a plate graphic featuring the healthy reference diet would decrease objective measures of the amount of meat taken and therefore the environmental impact of student meals.
The specific goal of this pilot study is to evaluate if it is possible to detect a statistical difference in postprandial glycemia after meals served with and without a drink previously shown to reduce postprandial glycemia by about 25%. A third drink, with a new recipe, is also included for comparisons. Six participants will carry continuous blood glucose monitors for 10 days and follow a specific meal schedule. The data from this study will form the basis for forming hypothesis of future studies as well as make appropriate calculations of statistical power.
Lowering sugar-sweetened beverage (SSB) consumption is a central component of lifestyle behavior change aimed at preventing and managing obesity, yet effective reduction of SSB intakes has been met with many challenges. While their palatability, accessibility, publicity, affordability, and social acceptability contribute to frequent and sustained SSB consumption, their caffeine and sugar content may further encourage continued intake. Although adverse health consequences of excessive SSB consumption are well documented, the extent to which their pleasant taste (due primarily to their sugar content) and post-ingestive effects (due to their sugar and/or caffeine content) positively reinforce consumption among children has not been elucidated. The purpose of this study is to conduct a pilot intervention to examine the feasibility of removing caffeinated SSBs from the child diet and to explore whether caffeinated SSB removal induces withdrawal symptoms in 8-11 (3rd-5th grade) year old children. Participants will be randomly assigned to replace their usual caffeinated SSB consumption with either caffeinated SSBs, caffeine-free SSBs or sparkling water provided by the study team for two weeks.
This study investigates the aspects related to the intake of food and nutrients, physical activity and sedentary behavior of Spanish children from 1 to 9 years. Furthermore, the investigators will know if the consumption of dairy products is associated with a better dietary pattern. Hypothesis: The habitual consumption of dairy products as part of a regular diet is associated with a better dietary pattern and a higher global diet quality.
There is little information on the dietary intake, absorption, metabolism and bioavailability (degree to which a substance becomes available to the target tissues upon administration) of polyphenols (natural substances present in a variety of foods) in human participants. This study assessed the bioavailability in healthy participants of polyphenols from 2 supplements containing green tea and green coffee extracts. Eleven participants were recruited and their habitual diet was assessed to estimate polyphenol intake. After completing a 24-hour urine collection, participants were given six green tea extract and three green coffee extract tablets, which they took daily for a period of 8 weeks. No tablets were taken during the last 4 weeks of the study. Further 24-hour urines were collected at 2, 4, 8 and 12 weeks. Participants were required to attend HNR (medical laboratory) the day after each 24hour urine collection. At these visits, they were asked to bring along their urine collections, completed documents (urine collection sheet, checklist for tablet intake/side effects) and any remaining supplements, which were used to assess tablet compliance. The investigators identified and quantified the amount of polyphenols in the supplement tablets as well as the amount of polyphenols and their metabolites in urine. The investigators then evaluated polyphenol bioavailability from the relationship between their dietary intake and urinary output. Evidence from this research could inform future intervention studies by providing data on the bioavailability of green tea and coffee polyphenols, and on the individual differences related to phenolic intake.
There is a lot of confusion when it comes to understanding nutrition information on food packages, thus making it difficult for consumers to choose healthy products. In today's busy and fast-paced shopping environment, mobile digital technology (for example, Smartphone applications) can help consumers make 'healthier' food choices when they are shopping. This study aims to test the effectiveness of a traffic light front-of-pack system, the Health Star Rating System (HSR or Star System), and the proposed sodium, saturated fat and sugar warning labels proposed by Health Canada. The study will also experimentally test the use of a Smartphone application (app), FoodFlip, to help educate consumers on these systems on food packages to explore the impact of a learning effect on the efficacy of the labelling systems.
Optimal infant and young child feeding practices are largely inadequate in rural and poor households in Ghana. Child welfare clinics (CWCs) focus on immunization, supplementation, and growth monitoring and promotion (GMP) activities among infants and young children (IYC). An essential component of GMP activities is to counsel mothers to practice optimal IYC feeding and health practices, but most of the time this is completely missing or not specific enough to be effective. This study will test the effect of a mass media nutrition education program on caregiver infant and young child feeding knowledge, attitudes and practices using a community-based cluster randomized design. Formative research will first be undertaken to determine the beliefs, attitudes, and constraints that prevent caregivers from adequately feeding their infants and young children with members of the community (caregivers with children under-five, men and elderly women).The information gathered will then be used to design specific messages that directly address the IYC feeding challenges of the community. Clusters will be randomized into active (radio messages with in-person engagement and follow-up) and passive (only radio messages) arms of the intervention. Farm Radio International (implementers of the mass media programming) will ensure the regular broadcast of twice weekly messages for a period of about 12-18 months.
The proposed Church Bridge intervention project will provide an innovative, evidence-based and technology supported, health intervention model for Southern, African American, and rural populations who continue to be disparately burdened by obesity and associated co-morbidities (i.e., hypertension, diabetes, cardiovascular disease). By targeting young adults (21-50 years of age) with families, the project will contribute to the long-term reduction of preventable chronic disease and related health care costs for the public.
