Protocol Number: 22DK0002 Title: Effects of Ultra-processed versus Unprocessed Diets on Energy Metabolism Background: Many diets worldwide include both processed and unprocessed foods. Researchers want to study the effects these foods have on a person s health. Objective: To study how different diets affect a person s health and metabolism. Eligibility: Adults aged 18 60 without diabetes who have stable weight and can exercise. Design: Participants will be screened with: Medical history Physical exam Heart tests Resting energy expenditure (to determine calorie needs) Blood and urine tests 20-minute stationary bicycle session Food, diet, and mental health questionnaires Participants will stay at NIH for 4 weeks. They will receive 3 meals a day and may eat as little or as much as they want. The diet will change each week. Their weight will be recorded daily. They will ride a stationary bicycle daily. Each week, they will do the following: Spend 1 day in a special room that assesses their metabolism Have 24-hour urine collections Give skin and fecal samples Repeat some screening tests Have scans to measure body fat Complete computerized behavior tasks Wear an activity monitor to track physical activity Wear a glucose monitor. A sensor will be inserted under the skin with a small needle. It will be replaced weekly. Take taste tests. They will swish water and flavored liquids around in their mouth and pick which ones had a non-neutral taste. They will also compare liquids for which ones taste better. Participation will last for 4 weeks. Sponsoring Institution: National Institute of Diabetes and Digestive and Kidney Diseases ...
The aim of the study is to provide proof of the effectiveness, acceptability, healthfulness and nutritional adequacy of dietary guidelines to reduce greenhouse gas emissions. The study will compare the effect of dietary advice based on 1) healthy climate-friendly dietary guidelines (intervention group) or 2) standard healthy dietary guidelines (control) on greenhouse gas emissions associated with dietary intake over 12 weeks.
The purpose of this study is to assess whether introducing table olives into the diet results in health-related benefits for young adults. Several studies have shown that addition of olives as part of somebody's diet has a positive impact on cardiovascular, metabolic, and inflammatory factors. However, there have not been many studies among young, healthy adults. This study will compare levels of specific biomarkers, collected through blood draw, at the beginning of the study and after 5 weeks, to evaluate the effects of investigational daily olive consumption.
There is sufficient evidence on the beneficial effects of fish consumption on health, mainly associated with the content of omega-3 polyunsaturated fatty acids (EPA and DHA) present mainly in blue fish. Different national and international organizations have issued recommendations on the optimal amount of fish that the population should consume to prevent certain chronic diseases related to diet. Thus, the WHO recommends eating fish regularly (1-2 servings per week for healthy adults) to ideally provide the equivalent of 250 mg of omega-3 fatty acids (EPA + DHA). Not reaching the optimal levels of EPA + DHA increases the risk for cardiovascular diseases, increasing the risk of death according to certain epidemiological studies. In this sense, using more precise techniques such as membrane lipidomics, allow adequate quantification and monitoring of fatty acid levels present in our body and how this lipid profile can change according to metabolism and diet. The objective of this study is to carry out a clinical trial of nutritional intervention with an adult population without pathologies that has a low consumption of fish (<2 servings / week) to evaluate the effectiveness of an intervention strategy based on increasing the number of fish servings through a controlled intake of fresh and canned fish. The results aim to show that increasing fish intake has an impact on lipid metabolism and in the future, for the prevention of certain chronic diseases, the introduction of canned fish can be a healthy strategy to increase fish consumption to long term.
This study will focus on improving brain health through dietary modification of added sugars in middle aged adults (50- 64 years old). Participants will be fed two 10-day diets (one diet containing 5% of total energy from added sugars and one diet containing 25% of total energy from added sugars) and examine blood vessel function, hippocampus structure using a MRI, and memory performance.
This randomized, double blind, controlled trial investigates changes in the cardiovascular index (triacylglycerol/HDL-cholesterol × waist/hip ratio) after 12 weeks of marine protein hydrolysate (MPH) or whey protein powder (placebo) supplementation in adult healthy persons. Additionally, the study investigates potential effects on plasma parameters of metabolic health including lipids, glucose, inflammatory parameters and redox state, as well as associations between dietary MPH and body weight, abdominal obesity, body composition, and gut microbiota composition. Finally, putative end-products of diet-microbial interactions (TMAO and short-chain fatty acids) with CVD risk factors and biomarkers of mitochondrial function are examined.
Study Design: Randomised controlled trial Study Participants: Healthy volunteers from the UK Planned Sample Size: 500 Planned Study Period: June - December 2021 Objectives and Outcome Measures: 1. Primary - Objective: To investigate the effect of promotions on the total number of calories selected - Measure: Difference in the absolute energy (kcal) of the final basket between the two groups 2. Secondary Objectives: - To investigate the effect of promotions on the nutritional content of the items selected overall, and across the individual target food categories - To explore the impact of removing promotions by socioeconomic status Measures: - Difference in the absolute sugar (g, kcal, %E), salt (g), and saturated fat (g, kcal, %E) of the final basket between the two groups - Difference in the absolute energy (kcal), sugar (g, kcal, %E), salt (g), and saturated fat (g, kcal, %E) between the two groups across the individual target food categories - Analyses of the primary and secondary outcomes specified above by gender, age group, ethnic group (White vs Non-White), BMI stratified into <30 and ≥30kg/m2 groups, education level (lower vs. higher), and household income (lower vs. higher) 3. Exploratory outcomes: - Objective: To investigate the acceptability of the intervention - Measures: Rating scores and open-ended answers from the follow-up questionnaire
Open labelled, virtual home based study to assess the test repeatability and the failure/rejection rate of the samples collected at home by participants.
The aim of the project is to study of the influence of Lettuce crop enriched with Molibdenum on hematological parameter. Secondary outcome to find out Molibdenum presence in urine in order to evaluate vegetables, like little crop, as Molibdenum biocarrier.
