Filter by:This study will evaluate the effects of diet composition (i.e., amount of protein and carbohydrate) during a 6-month weight loss intervention and 12-months of follow-up on physical function, muscle mass, and weight loss maintenance in obese older adults. Participants will receive either a protein or carbohydrate supplement along with a behavioral weight loss intervention.
This study evaluates the role of dietary L-tryptophan, an essential amino acid, in the activation of a specific cellular component: the aryl hydrocarbon receptor.
The overall aim for this study is to evaluate the clinical effects of a modified diet on metabolic risk factors such as diabetes mellitus and obesity, and the mechanisms this nutrition composition exerts on gastrointestinal physiology, inflammatory responses, and quality of life, where the subjects are their own controls. Within this study, the investigators will be able to relate the nutritional composition to metabolic disorders, the gut microbiota, secreted intestinal neuropeptides, and bio- and inflammatory markers in serum, plasma and urine.
Histamine is a biologically active component that can be found in many foods and beverages. Intake of excessive histamine from foods or beverages, can trigger symptoms including urticaria. A low histamine diet has been recommended as one of the possible treatments for patients with chronic urticaria. There are very few studies to confirm the effectiveness of such diets and, to the investigators' knowledge, none from Asia where high histamine containing meals are often eaten (personal observations). The objective of the present study is to investigate the therapeutic effect of low histamine diet in relieving symptoms in patients with chronic urticaria with or without angioedema, and / or pruritus (U/A/P). The investigators hypothesize that following a low histamine diet for 4 weeks, the symptoms of patients with chronic U/A/P should improve.
