Cardiorespiratory fitness (CRF), also known as "exercise capacity", is the capacity of respiratory and circulatory systems to supply oxygen to skeletal muscle during exercise for the generation of energy. Determinants of CRF include lung capacity, capillary density, cardiac output, hemoglobin concentration, and mitochondrial function. The research group studies how CRF is related to fuel utilization, yielding a mechanistic understanding of the association between lower CRF and worsening metabolic health via mitochondrial function. The objective of this study is to measure fuel utilization in response to habitual diet for one week in adolescents and young adults, ages 14-22 years (n=30). Fuel utilization will be estimated by glucose measures using a continuous glucose monitor (CGM). Habitual dietary intake will be collected via a mobile phone application (BiteAI, Inc) that uses artificial intelligence to extract nutrient information from food photographs. Participants will undergo two standard of care (SOC) meal tolerance tests at home - a glucose tolerance test and a Ensure® mixed meal tolerance test. CRF will be estimated by measuring maximum oxygen consumption (VO2 max) during a graded treadmill test. The hypothesis is that a higher VO2 max will be associated with increased fuel utilization, measured by lower glucose response to the SOC meal tolerance tests. The proposed study is described in the following aims: SPECIFIC AIM 1. Test for feasibility of completion of self-report dietary food records, completion of two at home meal tolerance tests that are standard of care for metabolic health screening, and completion of a seven-day continuous glucose monitor. SPECIFIC AIM 2. Identify nutrients and foods that are associated with an elevated glucose response. SPECIFIC AIM 3. Assess the influence of VO2 max on the glucose response to the SOC glucose tolerance test and Ensure® mixed meal tolerance test.
The purpose of this study is to evaluate the impact of Benazir Nashonuma Program (BNP) which includes specialized nutritious food (SNF) augmented with specific reproductive health interventions during pregnancy on proportion of low birthweight babies and stunting among children, in low income setting of Pakistan. The study aims to answer if: 1. Utilization of Benazir Nashonuma Program (BNP) among pregnant women is effective in reducing the proportion of low birthweight babies, compared to pregnant women who are not utilizing the program, among low income setting population. 2. Utilization of Benazir Nashonuma Program (BNP) is effective in reducing the proportion of stunting among children, compared to those not utilizing the program, among low income setting population. Participants who are enrolled in the Benazir Nashonuma Program (receiving intervention) and those who are not enrolled (not receiving intervention) will be followed throughout pregnancy till delivery. After delivery mother-baby dyad will be followed for a period of 12 months. Compliance of supplementation will be measured, and outcomes (low birthweight and stunting) observed throughout the follow up.
The FORX (Food intervention to Reduce immunotherapy toXicity) trial will assess whether supplementing dietary fiber intake by providing weekly boxes containing 30 different plants to patients with solid tumors starting immune checkpoint inhibitor therapy affects the incidence of immune related adverse events.
The goal of this clinical trial is to to test the effects of dietary composition, on the rhythms of food intake and appetite regulation, and rhythms of energy expenditure. Participants will: complete 2 field-based dietary interventions be provided with standard meals record daily food intakes in a real-time manner complete 2 inpatient stays be provided with standard meals have frequent blood draws provide urine, saliva, stool and rectal swab samples
The purpose of this randomized controlled trial is to assess the impact of different nutrient profiles for magnifying glass front-of-package labels (FOPLs) on consumer choices in an online grocery store. Participants will be adults residing in Brazil recruited through a survey research firm. Participants will be randomly assigned to one of three shopping environments in an online grocery store. Participants will complete a shopping task (selecting items from a pre-specified shopping list) in the online grocery store. After completing the shopping task, participants will be rerouted to a computer survey. The survey will include standard behavior and label perception questions, as well as demographic items.
The goal of this randomized clinical trial is to compare an antiinflammatory and environmentally friendly dietary strategy (AIA-D) designed based on the planetary health diet recommendations translated to the regional context and including nutrients related to antiinflammatory responses with an active control diet based on general healthy diet recommendations (CONV-D) in adults from 18 to 50 years of age with obesity (body mass index ≥30 kg/m2). The main questions it aims to answer are: - If the intervention with AIA-D will cause a significant decrease at the end of the intervention (six weeks) in lipopolysaccharide-binding protein (LBP) compared to CONV-D. - If intervention with AIA-D will cause a significant increase at the end of the intervention (six weeks) in the relative abundance of two specific bacteria genera (AM and FP) when compared to CONV-D. Participants will: - Sign the informed consent. - Provide two peripheral blood samples (taken by our trained professionals). - Provide two samples of feces. - Allow anthropometric (body weight, height, hip and waist circumferences) blood pressure measurements on two occasions. - Respond to 24 h dietary recall on two occasions. - Attend the 1-hour group sessions requested (three for AIA-D and one for CONV-D). - Follow the dietary recommendations provided. - Be willing to participate in social media groups to receive information and follow up during the six weeks of the intervention. Researchers will compare an antiinflammatory and environmentally friendly strategy (AIA-D) with an active control diet (CONV-D) based on general healthy diet recommendations to see if AIA-D decreases metabolic endotoxemia measured through LBP serum levels and increase the relative abundance of AM and FP, compared to CONV-D.
The goal of this investigational study is to develop algorithms that predict human response to foods. The main question it aims to answer are: - How does varying foods and eating patterns impact one's biological and physiological responses? - In what ways can novel dietary assessment measures be used to improve dietary assessments and to prescribe assessments to people in future research with increased precision? - Can artificial intelligence and machine learning techniques be combined to prescribe foods and eating patterns to individuals for optimization of their health? There are 3 Modules participants may take part in: - Module 1- A participant's dietary intake and accompanying nutritional status, biological and other measures will be observed over 10 days, as well as physiological responses to a liquid mixed meal tolerance test will be measured. - Module 2- Participants will undergo three controlled dietary interventions provided for 14-days each and separated by washout periods of at least 14 days. Physiological responses following a diet-specific meal test will be measured. - Module 3- Participants will undergo the same three dietary interventions during the same 14 day periods as Module 2 while being studied in-residence. Physiological responses following a liquid mixed meal tolerance test and a diet-specific meal test will be measured.
The average adult in the US consumes over 1/3 of a cup of sugar each day, or nearly 300 calories worth, with the primary sources being from beverages, desserts and sweet snacks, candy, additions to beverages, and foods such as breakfast cereals. This is a risky health behavior, as high added sugar intake relates to higher risk of gaining weight, blood sugar disorders such as type 2 diabetes, plus heart disease and various cancers. Thus, high added sugar intake is problematic, and something in need of reducing. Therefore, the investigators are proposing to test how commercial foods sweetened with a new, FDA approved rare sugar with net zero calories (allulose), that is derived from dried fruits, brown sugar, and maple syrup may impact added sugar intake and usual blood sugar levels. The investigators are doing this by a randomized trial, in which the investigators will recruit participants with abnormal blood sugars (prediabetes or diabetes) or higher metabolic risk (bigger waist and elevated blood pressure or blood cholesterol) and ask them in random order to include foods in their usual dietary intake that are sweetened by regular sugars (regular sugar), foods that are sweetened by the zero calorie rare sugar allulose (low added sugar), or low added sugar intake by higher intake of fresh fruits and minimally processed and sweetened foods in place of usual sweetened foods. The investigators will measure their usual blood sugar levels for each of these 3 different 2- week periods with a blood glucose monitor, along with what they eat each of those periods, their blood pressure, and how the different dietary approaches impact how they feel.
