Filter by:This single-center, randomized controlled pilot study aims to evaluate the efficacy of TruHeight Growth Protein Shake on improving growth patterns in children aged 4-17 years. Over six months, participants will consume the protein shake daily, five times a week, with outcomes measured in terms of type X collagen concentration in urine, height via a stadiometer, and body composition using an INBODY device.
The study is a prospective, controlled, randomized two-arm longitudinal crossover trial, performed in a single-centre. Hence, the investigators designed a clinical study aimed to investigate the effects of a daily intake of soffritto in overweight or obese class-1 individuals without other cardiovascular risk. After a run-in period of two-week, participants were randomly separated in two different intervention sequences (two-arms) of six-weeks in which volunteers were administered with a soffritto (100 g/day) or a control group (without soffritto). After the first six-week period, participants had a wash-out phase of two-week followed by a second six-week period in which groups exchanged their interventions. During the duration of the study, the volunteers were asked to maintain their usual diet, excluding raw or cooked tomatoes, as well as tomato-based products (sauces, ketchup, juices, etc.) other than those administered during the study in the corresponding periods.
Product acceptability data from 15 participants are required in order to submit an application to the Advisory Committee on Borderline Substances (ACBS) and the Health Service Executive (HSE) submission for Ireland for product registration.
The goal of this experiment is to test the effects an "ultraprocessed" warning label on foods and beverages among Brazilian consumers. The main questions it aims to answer are: - Do "ultraprocessed" warnings affect Brazilian consumers' intention to purchase products? - Do "ultraprocessed" warnings affect Brazilian consumers' product perceptions? Participants will see images of four products carrying either nutrient warning labels (which are currently mandatory in Brazil) or nutrient warning labels alongside an experimental warning label informing that the product is ultraprocessed. Participants will then answer survey questions about each product. Researchers will compare responses between both arms to determine if the "ultraprocessed" warning significantly changes the effect of nutrient warnings.
The aims of this study is to investigate the effect of eucaloric high protein and fiber diet on healthy subjects.
Body weight can be affected by the content of fat and carbohydrate in the diet. On average, people will lose a modest (< 5 kg) amount of weight when switched from a high fat diet to a low fat, high carbohydrate diet. Determining mechanisms whereby changing the makeup of the diet can change one's body weight will be important in understanding why body weight in the US population is trending upward recently and what health care providers can recommend to reverse this trend. Previous studies have shown that increasing the carbohydrate and lowering the fat content in the diet leads to a change in the appearance of the hormone leptin in the blood over 24 hours. Leptin is an important signal from the fat cell to the brain that leads to a reduction in appetite and weight loss. A previous study found that after keeping people's weight stable, that the greater rise in leptin over the day on a low fat-high carbohydrate diet compared to a high fat diet predicted the reduction in calories they ate over a subsequent 12 weeks when their weight was allowed to freely fluctuate. Recent studies have also provided evidence that limiting fat and increasing the amount of protein in the diet also leads to modest weight loss. It is therefore proposed to test whether low fat, high protein diets also result a change in leptin secretion, and if this change predicts a reduction in appetite when they are allowed to eat freely.
A trial study was proposed as part of the project "Biocomposite Packaging for Active Preservation of Food" (acronym BIOFOODPACK) that has been funded by the M-ERA.Net Call 2016. A crossover trial with a behavioral intervention study will be conducted. The behavioural intervention treatment consists of: i) avoiding the consumption of packaged (cans, plastic, paper) ready to consume foods, and foods from take away/delivery/fast food, and ii) using the proposed bio-based packaging material to package foods ready for consumption; this bio-based packaging material (Silvex Ltd, Portugal) does not contain plasticizers, it is biodegradable and made out of plant-based materials (corn, starch, etc.). The objectives of this study are: 1. To describe the body burden of plasticizers for women aged 18-40 years systematically adopting the intervention treatment package during the 5-day period. 2. To assess the diurnal variability of the plasticizers, based on regular daily activities of the young adult women.
This study will examine two separate interventions: 1) the effects of ischemic preconditioning or 2) a high fat meal on the capacity of the brachial artery to overcome sympathetic activation and dilate during exercise (also known as functional sympatholysis). Participants will be asked to complete rhythmic handgrip exercise with and without the application of -20 mmHg lower body negative pressure to increase sympathetic activation. Doppler ultrasound will be used to continuously measure brachial artery blood flow. Participants will complete the handgrip exercise and lower body negative pressure before and after the applications of each interventions. Participants may elect to only complete one intervention rather than complete both protocols. Intervention one is active or control ischemic preconditioning. Intervention two is high or low fat meals.
Diets containing fruit rich in anthocyanins have been shown (in meta-analyses) to be beneficial for health, but intervention trials have shown inconsistent results. In this preliminary study we want to investigate the influence of a tart-cherry juice intervention on vascular function and explore metabolite profiles that may offer insight into their mechanism of action
This study will investigate the effects of high-protein, high-fat snacks, specifically Greek yogurt, and peanuts, on satiety, gut hormones, and insulin secretion in overweight and obese women. The hypothesis posited that peanuts will exhibit a more beneficial impact on satiety, gut hormones, and insulin levels compared to Greek yogurt. The two-arm parallel randomized trial will involve 52 participants aged 30 to 40 with a BMI between 25-35 kg/m²,and they will be randomly divided into peanut (n=26) and Greek yogurt (n=26) groups. Pre-snack, BMI and dietary intake will be assessed. Appetite sensations will be gauged using a visual analog scale (VAS) upon arrival, and at 30- and 60-minutes post-snack. Pre- and post-snacking, plasma levels of cholecystokinin (CCK), Peptide Tyrosine-Tyrosine (PYY), Glucagon Like Peptide-1 (GLP-1), Ghrelin (GHRL), and insulin will be analyzed.
