NCT ID: NCT03796897 Not yet recruiting - Clinical trials for Dietary Modification

Supplementation of a Leucine-enriched Protein Blend

Start date: March 2019
Phase: Early Phase 1
Study type: Interventional

It is well known that dietary protein transiently stimulates muscle protein synthesis (MPS) whereby changes in MPS in response to feeding may be regulated by specific downstream target proteins of mammalian target of rapamycin signaling, such as S6K1, rpS6, and eIF2B. A meal deficient in protein, however, does not increase the rate of MPS because a rise in the bioavailability of amino acids does not occur. In addition, the source of dietary proteins has been shown to impact postprandial blood levels of amino acids. The concept that certain types of proteins are "fast acting" or "slow acting" has been shown to affect the postprandial profile of amino acids appearing in the systemic circulation. Native whey and micellar casein are both dairy proteins that contain a similar amount of essential (EAA), but blood EAA levels increase faster and to a higher level after the consumption of whey protein. Differences in gastric emptying, digestion and absorption kinetics between micellar casein and native whey are the underlying factors. Nonetheless, micellar casein protein has been shown to protract MPS in humans. Despite the significant amount of information gained with respect to both of these protein sources, the effects of combinatorial formulations on the postprandial profile of amino acids appearing in the blood is less well known.

NCT ID: NCT03781011 Recruiting - Clinical trials for Cardiovascular Diseases

Oral Carnitine Challenge Test Guides Personalized Therapy for Cardiovascular Disease

Start date: October 19, 2018
Phase: N/A
Study type: Interventional

The investigators plan to use our recently developed oral carnitine challenge test (OCCT) as a tool to exam individual's trimethylamine N-oxide (TMAO) production capacity from their gut microbiota. By using data collected by OCCT, the investigators defined subjects as TMAO high producer or TMAO low producer and apply low carnitine/choline diet as dietary intervention in accordance. After dietary intervention for two months, the investigators repeated OCCT for these participants and compare the TMAO production capacity before and after dietary intervention.

NCT ID: NCT03755232 Not yet recruiting - Healthy Clinical Trials

Acute Glycemic and Insulinemic Response of FOSSENCE™

Start date: December 1, 2018
Phase: N/A
Study type: Interventional

Short chain fructooligosaccharide (FOS) is known as a prebiotic fiber/nutrient and has been documented to demonstrate different health benefits including glucose control, gut health, mineral absorption, weight and immunity. FossenceTM is a short chain fructo-oligosaccharide (scFOS), sweet tasting, soluble prebiotic dietary fibre which is produced through Tata Chemicals Limited's patented process and is currently US GRAS notified (safe for consumption). The formulation and properties of scFOS suggest that the molecule may potentially play a role in glucose and insulin metabolism. The purpose of this study is to explore the rise of glucose and insulin in the blood after consuming FossenceTM that has been added or substituted into a sugar drink or white bread.

NCT ID: NCT03710200 Recruiting - Clinical trials for Dietary Modification

Breads Made With Triticum Heritage Varieties: Effect on Post-prandial Glycemia and Insulinemia

Start date: October 12, 2018
Phase: N/A
Study type: Interventional

Wheat is one of the most important crop for humans and it represents a source of multiple nutrients, dietary fiber and bioactive compounds, especially if consumed as wholegrain. Several studies have suggested that Triticum heritage varieties could present a healthier and better nutritional profile than modern wheats, by providing more vitamins, minerals and nutraceutical compounds. Although the effect of ancient grain consumption have been partially investigated in both animal and human studies, the potential impact of Triticum heritage varieties compared to modern ones on post-prandial glucose metabolism is still unclear. Thus, the aim of the study was to evaluate the impact on post-prandial glycaemia and insulinemia of different types of breads formulated with flours derived from mix of heritage varieties belonging to the Triticum genus selected and cultivated in specific areas of Emilia Romagna region, compared to breads made with conventional/modern wheat flours.

NCT ID: NCT03700710 Recruiting - Blood Pressure Clinical Trials

Remote Dietary Counseling to Promote Healthy Diet and Blood Pressure

Start date: January 16, 2019
Phase: N/A
Study type: Interventional

Recent American College of Cardiology/American Heart Association (ACC/AHA) hypertension guidelines recommend lifestyle modification for patients with BP >= 130/80 mmHg. While eating a Dietary Approaches to Stop Hypertension (DASH)-type diet, increasing physical activity, and weight loss have been shown to reduce blood pressure (BP), limited resources are available in the primary care setting to help patients make these changes. In this study, the investigators will compare the efficacy of a self-guided vs. dietitian-led approach using web-based lifestyle modification tools to reduce weight, improve dietary quality, and lower blood pressure in overweight/obese adults with untreated hypertension.

NCT ID: NCT03698929 Active, not recruiting - Clinical trials for Dietary Modification

Effect of Dietary Cholesterol on Plasma Lipids

Start date: September 17, 2018
Phase: N/A
Study type: Interventional

The Physicians Committee is carrying out a research study to improve the investigator's understanding and expand the literature to quantify the effect of foods on blood cholesterol. This study will measure changes in low density lipoprotein (LDL) concentration, sometimes called "bad cholesterol," over 2 study periods of 4 weeks each, with 1 rest week in between. Approximately 50 subjects will participate in this study.

NCT ID: NCT03691545 Recruiting - Physical Activity Clinical Trials

Making Healthy Choices: Does Having an Online Health Coach Help?

Start date: October 1, 2018
Phase: N/A
Study type: Interventional

Participating in regular physical activity and consuming a diet high in fruits and vegetables can aid in the management of various acute and chronic side effects of cancer treatment; however, few rural-dwelling young adult cancer survivors are active enough and consume enough fruits and vegetables to accrue benefits. Telehealth interventions show promise for helping these young adults increase their motivation to participate in these behaviours by addressing barriers associated with accessing face-to-face behaviour counselling services (e.g., time commitment, travel distance). Yet, few researchers have examined the feasibility and acceptability of a telehealth intervention that provides motivational support grounded in self-determination theory for these health behaviours in rural-dwelling young adult cancer survivors. Based on previous research, the researchers reasoned that rural-dwelling young adult cancer survivors' physical activity and fruit and vegetable consumption would be more likely to increase if they participated in a telehealth intervention therefore, the researchers aim to test the feasibility, acceptability, and preliminary efficacy of the intervention. The researchers also aim to assess if changes in perceived basic psychological need satisfaction, behaviour regulation, and perceived autonomy support are associated with changes in physical activity and fruit and vegetable consumption.

NCT ID: NCT03691155 Recruiting - Crohn Disease Clinical Trials

The Feasibility of Following the Crohn's Diet

Start date: July 8, 2018
Phase: N/A
Study type: Interventional

A research team from King's College London are investigating how diet can be used as a treatment for Crohn's disease. The investigators have designed a new diet and eventually wish to test whether the diet can be used to manage Crohn's disease and reduce gut inflammation. Before doing this, the investigators need to find out how practical it is for people to follow the diet for 14 days by conducting this 'feasibility' study. A feasibility study is a small study that aims to highlight any issues before informing the design of a larger research trial. The diet the investigators have designed is called the Crohn's Diet. The evidence for this diet is based on recent research which suggests that certain food ingredients may be involved in triggering gut inflammation. The study's primary aim is to assess the practicalities of following the Crohn's Diet. It will also assess compliance to the Crohn's Diet and if following it changes the nutritional balance from the normal diet.

NCT ID: NCT03689504 Not yet recruiting - Malnutrition Clinical Trials

Evaluating a Family-based Nutrition and Garden Intervention in Rural Guatemala

Start date: October 20, 2018
Phase: N/A
Study type: Interventional

This is a pilot quasi-experimental study to evaluate the impact of adding a family garden intervention to an existing wrap-around nutrition intervention for children with chronic malnutrition and their family. The existing nutrition intervention is provided by community health workers affiliated with Wuqu' Kawoq | Maya Health Alliance. A single community in rural Guatemala will participate in the intervention, with the goal to recruit approximately 70 families in the combined nutrition/garden intervention. A nearby community, also participating in the nutrition intervention, will serve as a nonrandom contemporaneous control. Aims of the study include: 1. Evaluate the impact of the garden intervention on maternal and child dietary diversity, child growth and household food insecurity. 2. Use the Reach Effectiveness Adoption Implementation Maintenance (RE-AIM) framework to conduct a preliminary implementation analysis, to guide a future, well-controlled study.

NCT ID: NCT03681054 Recruiting - Clinical trials for Dietary Modification

Dietary Management of Gestational Diabetes

Start date: December 3, 2018
Phase: N/A
Study type: Interventional

eMOM is a randomized, controlled trial to compare the effects of two different dietary interventions during pregnancy. The comparison is based on tissue glucose content (using continuous glucose monitoring system) in pregnant women and on neonate body composition. The recruited women (n=60) have been diagnosed with gestational diabetes mellitus, are overweight (BMI≥25 kg/m2) and of Caucasian origin. Of the study diets, one is moderately carbohydrate restricted and the other one is high on plant-based protein with an emphasis on healthy Nordic foods. The study has two two-week study periods that are carried out on approximately gestational weeks 24-28 (period I) and 34-36 (period II). Continuous glucose monitoring and other measurements (accelerometer, 3-day food record, gut microbiota, serum lipids, metabolomics, epigenetics etc.) are done during these study periods. At the beginning of the study, before study period I, the participants are randomized to either one of the intervention diets. The first study period consists of a crossover phase in which the participants receive three days' worth of food according to one of the intervention diets (according to the randomization) after which there is a three-day wash-out period. After the wash-out period, the participants receive three days' worth of food according to the other diet. After the first study period, a nutritionist advises the lastly followed intervention diet to the participant and the diet is followed until delivery. To ensure the diet is followed, the participants gets at least three personal face-to-face counseling sessions, phone calls, mobile reminders, recipes and food items. After delivery, the infant's body composition, epigenetic markers of cord blood and placenta, gut microbiome and urine metabolomics are measured.
