NCT ID: NCT03432104 Completed - Clinical trials for Dietary Modification

Evaluation of Bioavailability of Phenolic Compounds From Oxxynea®

Start date: February 23, 2018
Phase: N/A
Study type: Interventional

The aim of this study is to evaluate bioavailability and pharmacokinetics of phenolic compounds from Oxxynea®, a blend of fruit and vegetable extracts, in healthy volunteers, during a randomized, double-blind and cross-over trial. After a single dose supplementation, both metabolic profile and urinary excretion will be determined over a 48h-period by means of High-Performance Liquid Chromatography coupled with a tandem mass spectrometry (HPLC-MS) to identify and quantify phenolic metabolites. In parallel, post-prandial potential anti-oxidative and anti-glycemic properties of Oxxynea® will be determined in blood, following consumption of a cafeteria-type breakfast.

NCT ID: NCT03403166 Completed - Blood Pressure Clinical Trials

Metabolomics of the Dietary Approaches to Stop Hypertension (DASH) Dietary Pattern

Start date: August 1993
Phase: N/A
Study type: Observational

The present record represents a secondary data analysis of the Dietary Approaches to Stop Hypertension (DASH) trial. Study data and specimens were accessed through the National Heart, Lung, and Blood Institute (NHLBI) Biologic Specimen and Data Repository Coordinating Center (BioLINCC). A global, untargeted, metabolomic profile was used to investigate biomarkers of the DASH dietary pattern as well as blood pressure change.

NCT ID: NCT03396263 Completed - Dietary Habits Clinical Trials

Online vs. Face-to-face Nutritional Advice in Kuwait (EatWellQ8)

EatWellQ8
Start date: December 24, 2017
Phase: N/A
Study type: Interventional

The EatWellQ8 study aims to investigate the effectiveness of a mobile web application (e-Nutri), capable of delivering automated personalised nutrition advice, compared with face-to-face nutritional advice, in increasing diet quality. Dietary assessment is via the validated Food4Me FFQ (with an updated user interface that has been designed for better usability) and dietary feedback is derived according to adherence to an 11-item modified US Alternative Healthy Eating Index (m-AHEI).

NCT ID: NCT03319836 Completed - Critical Illness Clinical Trials

Meeting Protein Targets in Critically Ill Patients

PROTARGET
Start date: October 4, 2017
Phase:
Study type: Observational

This is a retrospective study of protein and energy intake in enterally fed critically ill adult patients before and after the introduction of a very high protein enteral nutrition formula in a single center medical/surgical ICU.

The EatWellUK study aims to investigate the effectiveness of a mobile web application (e-Nutri), capable of delivering automated personalised nutrition advice, in increasing diet quality. Dietary assessment is via the validated Food4Me FFQ (with an updated user interface that has been designed for better usability) and dietary feedback is derived according to adherence to an 11-item modified US Alternative Healthy Eating Index (m-AHEI).

NCT ID: NCT03235804 Completed - Clinical trials for Dietary Modification

The Impact of a Powdered Meal Replacement on Metabolism and Gut Microbiota

PREMIUM
Start date: April 1, 2019
Phase: N/A
Study type: Interventional

This study will investigate the impact of a 12-week powdered meal replacement on inflammatory, metabolic, and hormonal markers of obesity-associated conditions and to correlate this response to compositional shifts within the gut microbiota. Moreover, resting energy expenditure, body composition, appetite sensations and soy metabolomics will be explored. This study will be a randomized, parallel group, clinical trial of a 12-week nutritional intervention. A sample size of n=88 participants will be randomly allocated into one of the following groups: - Control group (CON): Participants will be asked to maintain their usual dietary intake over 12 weeks. Their usual dietary intake is expected to reflect the North American dietary pattern (i.e. ~15% of total energy intake coming from protein, ~50% from carbohydrate and ~35% from fat). - Powdered Meal Replacement group (PMR): Participants will be asked to maintain their usual dietary intake and consume a powdered meal replacement composed of soy protein, honey and yogurt twice daily (in two snacks) over 12 weeks. The addition of the meal replacement to a North American Dietary Pattern (described on the CON group diet) will result in a diet composed of, approximately, 22% of protein, 48% of carbohydrate and 30% of fat of total energy intake. The following variables will be analyzed: - Interleukin (IL)-6. - Gut microbiota diversity and composition, specifically taxa that have been associated with health benefits, obesity, and weight loss. - Systemic inflammatory biomarkers (high-sensitivity C-reactive protein, IL-8, IL-10 and tumor necrosis factor-α); - Metabolic blood markers (glucose, insulin, lipid panel, peptide tyrosine-tyrosine, glucagon-like peptide-1, ghrelin, adiponectin, leptin, free glycerol, free fatty acids, and thyroid stimulating hormone) - Resting energy expenditure; - Body composition; - Appetite sensations (hunger, satiety, fullness, and prospective food consumption); - Soy polyphenols' metabolomics. - Gene expression and genetic polymorphisms. At baseline and after 6 and 12 weeks, individuals will attend our Human Nutrition Research Unit where all assessments will take place. In order to assess participants' adherence and follow-up, dietary intake, body weight and appetite sensations (only for participants assigned to the PMR group) will be assessed weekly during the 12-week intervention period. Additionally, participants will be contacted by phone weekly and reminded to maintain their journal/log.

NCT ID: NCT03202914 Completed - Clinical trials for Dietary Modification

Metabolomics for Identifying Biomarkers of Dietary Intake and Kidney Disease Progression

MDRD
Start date: October 1988
Phase: N/A
Study type: Interventional

The present record represents a secondary data analysis of the Modification of Diet in Renal Disease (MDRD) Study. For this analysis, the MDRD study data and specimens were retrieved from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Central Repository. A global, untargeted, metabolomic profile was used to investigate biomarkers of dietary intake as well as biomarkers of kidney disease progression.

NCT ID: NCT03194334 Completed - Clinical trials for Dietary Modification

Creatine, Carnitine and Carnosine in Vegetarians

Start date: December 2012
Phase: N/A
Study type: Interventional

Balanced vegetarian diets are popular and contain health-promoting characteristics. A balanced lacto-ovo-vegetarian diet differs in nutrient intake from an omnivorous diet, e.g. by increased intake of fibre, magnesium and antioxidants, but lower intake of omega-3 fatty acids and vitamin B12. However, the impact of reduced to near absent intake of carnitine, carnosine and creatine in a vegetarian diet is less well established and could be relevant in relation to muscle function, exercise capacity and sports performance. Few longitudinal intervention studies investigating the effect of a vegetarian diet on the availability of these compounds currently exist. This study aimed therefore to investigate the effect of of transiently switching omnivores onto a vegetarian diet for 6 months on muscle and plasma creatine, carnitine and carnosine homeostasis. We hypothesized that homeostasis of creatine and carnosine would be disrupted when their dietary intake was missing. For carnitine, however, we hypothesized that homeostasis can be maintained given its slow turnover rate and its presence in some non-meat nutrients. A second aim was to investigate whether supplementation of creatine and beta-alanine (the rate-limiting precursor of carnosine synthesis), concurrently with a lacto-ovo-vegetarian diet, was able to correct for potentially emerging deficiencies.

NCT ID: NCT03146923 Completed - Clinical trials for Dietary Modification

Decreasing Intakes & Absorption of Phosphorus in Haemodialysis Patients Through Food Choices

DIP HD
Start date: March 6, 2017
Phase: N/A
Study type: Interventional

Based on new evidence renal dietitians in Ireland are revising the diet sheet that is used to teach patients about reducing blood phosphate. Changes that renal dietitians plan to make to the dietary phosphorus prescription - Inclusion of some nuts and pulses - More detailed education re phosphate additives - More accurate protein prescription - Inclusion of more whole grains - Encouraging the use of foods with a low phosphorus to protein ratio The investigators want to test the two diet prescription to find out, which one is better at reducing blood phosphate and which one is more acceptable to patients. The investigators also want to make sure it is safe.
