Filter by:The DECIDE - Diet (Diet, ExerCIse and carDiovascular hEalth - Chinese Heart Healthy Diet for People With High Cardiovascular Risk in China) is to evaluate the effects of CHH-diet in reducing blood pressure in Chinese people with high cardiovascular risk. The study will recruit 360 adults people from 4 centers in China. All eligible participants will participate in a 1-week run-in phase in which they are fed the usual Chinese diet. Participants who pass the run-in phase will be randomly assigned 1:1 to receive CHH-diet or usual diet with the use of a central concealed randomization procedure (simple randomization), stratified by center and batch. The intervention will last 28 days. Primary outcome will be the change in systolic blood pressure. The secondary outcomes include the differences between the two groups in the changes of diastolic blood pressure, total cholesterol, fasting blood glucose, 10-year CVD risk, gut microbial community and food preference score.
The objective of this project is to compare the effect of two widely implemented cancer diets, differing drastically in macronutrient content, on biomarkers of inflammation, compared to a control diet. Diet A will be a low-carbohydrate, high-fat ketogenic-type diet with an emphasis on whole foods. By limiting carbohydrate, the diet will have an extremely low glycemic load, thereby minimizing diurnal glucose and insulin excursions. Diet B will be a low-fat, high-carbohydrate whole foods plant-based diet. It will include only fiber-rich, low-glycemic index sources of carbohydrates and largely eliminate animal protein, which will minimize rapid spikes in blood glucose and insulin and the production of IGF-1. This diet is also hypothesized to improve glucose tolerance and insulin sensitivity, which should further help minimize diurnal glycemic and insulinemic excursions. Both diets will be compared to a control diet based on the 2015 USDA Dietary Guidelines for Americans (Diet C) in patients suffering from advanced lung cancer as they are completing medical therapy. The overarching hypothesis motivating this work is that a nutrient dense diet that minimizes known factors involved in tumor growth and progression may improve the effectiveness of therapy. Our specific hypothesis is that participants following either of the experimental diets, A or B, will experience a reduction in biomarkers of insulin resistance and chronic inflammation, both of which are known risk factors for progression in lung cancer, and a greater median time to progression compared to those on the control diet (Diet C).
The purpose of this study is to test if a parenting program can be used to prevent substance use among Latino youth and at the same time promote healthy eating. Pairs of 7th grade students and one of their parents will be enrolled in the study and randomly assigned to three groups: an existing parenting intervention focusing on substance use prevention (FPNG), the enhanced parenting intervention that also has nutrition content (FPNG+), and a comparison program focused on academic success. Only parents will attend intervention sessions. Data will be collected from the parent and their 7th grade student to see how these programs impacted substance use, nutrition, and parenting. The investigators hypothesize that families receiving the FPNG+ will have improved nutrition habits than the other conditions. Students in both FPNG and FPNG+ will have lower substance use rates as compared to the academic success program. In addition, the effects of parenting strategies and sociocultural factors on the FPNG and FPNG+ results will be studied.
The investigators propose an efficacy study (i.e., do salad bars work under controlled conditions in naturalistic settings) to test whether introducing salad bars in elementary, middle, and high schools that have never had salad bars affects students' FV consumption and waste during lunch. A cluster randomized controlled trial will test new salad bars against controls for 6 wks, with/without an additional 4-wk marketing phase .
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.
