Filter by:Since uncontrolled observational studies first linked fructose to the epidemic of obesity almost a decade ago, it has become a focus of intense concern regarding its role in the obesity epidemic. Despite the uncertainties in the evidence,the recommendations of international health organizations have cautioned against moderate to high intakes fructose-containing sugars, especially those from sugar sweetened beverages (SSBs). To improve the evidence on which nutrition recommendations are based, the investigators propose to study of the effect of fructose-containing sugar sweetened beverages (SSBs)on body weight, by undertaking a systematic synthesis of the data taken from all available clinical studies in humans. This technique has the strength of allowing all of the available data to be pooled together and differences to be explored in groups of different study participants (healthy humans of different sex, weight, and age and in those with diseases which predispose to disturbances in metabolism, such as diabetes) with dietary fructose in different forms, doses, and with differing durations of exposure. The findings generated by this proposed knowledge synthesis will help improve the health of consumers through informing recommendations for the general public, as well as those at risk of diabetes and cardiovascular disease.
Dietary pulses (beans, peas, chickpeas, and lentils), more commonly known as "legumes", are generally recognized as healthy components of the diet. Canada's Food Guide encourages consumptions of meat alternatives, such as beans "more often"; and the dietary guidelines for Americans both recommend consumption of 3 cups of legumes per week. However, there remains insufficient information on the usefulness of these foods in protecting heart health. To improve evidence-based guidance for dietary pulse recommendations, the investigators propose to conduct a systematic review of the effect of dietary pulse consumption on after-meal blood sugar levels, appetite, and food intake regulation to help explain their mechanism for improving longterm blood sugar and body weight control. The systematic review process allows the combining of the results from many small studies in order to arrive at a pooled estimate, similar to a weighted average, of the true effect. The investigators will be able to explore whether eating pulses has different effects between men and women, in different age groups and background disease states, and whether or not the effect of pulses depends on the dose and background diet. The findings of this proposed knowledge synthesis will help improve the health of Canadians through informing recommendations for the general public, as well as those at risk of heart disease and diabetes.

Canada's Food Guide encourages consumptions of meat alternatives, such as beans "more often"; and the dietary guidelines for Americans both recommend consumption of 3 cups of legumes per week. However, there still remain insufficient information on the usefulness of these foods in protecting heart health. To improve evidence-based guidance for non-oil-seed pulse recommendations, the investigators propose to conduct a systematic review of clinical studies to assess the effect of eating pulses in exchange for other foods on measures of heart disease risk and blood sugar control in humans. The systematic review process allows the combining of the results from many small studies in order to arrive at a pooled estimate, similar to a weighted average, of the true effect. The investigators will be able to explore whether eating pulses has different effects between men and women, in different age groups, in people with high or normal sugar or blood fat levels, and whether or not the effect of pulses depends on how much/often they are eaten. The findings of this proposed knowledge synthesis will help improve the health of Canadians through informing recommendations for the general public, as well as those at risk of heart disease and diabetes.
Diabetes and heart associations continue to discourage high intakes of dietary fructose, a constituent part of the sucrose molecule that is found in fruits and vegetables as a natural sugar and in some processed foods and beverages as an added sweetener. The concern relates to its ability to increase certain blood fats and cholesterol, which increase the risk of cardiovascular disease. The evidence for an adverse effect of fructose on these risk factors, however, is inconclusive. To improve the evidence on which nutrition recommendations for fructose are based, the investigators therefore propose to study the effect of fructose on blood fats, cholesterol, sugars, blood pressure, and body weight, by undertaking a systematic synthesis of the data taken from all available clinical studies in humans. This technique has the strength of allowing all of the available data to be pooled together and differences to be explored in groups of different study participants (healthy humans of different sex, weight, and age and in those with diseases which predispose to disturbances in metabolism, such as diabetes) with dietary fructose in different forms, doses, and with differing durations of exposure. The findings generated by this proposed knowledge synthesis will help improve the health of consumers through informing recommendations for the general public, as well as those at risk of diabetes and cardiovascular disease.
The purpose of this study is to measure the effect of ranolazine on ETT (exercise treadmill test) exercise duration in four ethnic subgroups with established coronary artery disease and risk factor(s) for the metabolic syndrome: Caucasian, African American, Southeast Asian and East Indian.
Metabolic syndrome is a combination of medical disorders that increase the risk of developing cardiovascular disease and diabetes. The exact mechanisms of the complex pathways of metabolic syndrome are not yet completely known. The pathophysiology is extremely complex and has been only partially elucidated. Most patients are older, obese, sedentary, and have a degree of insulin resistance. Stress can also be a contributing factor. The most important factors are: weight, genetics, aging, sedentary lifestyle,excess caloric intake. In our study we will assess the role of some polymorphisms in the pathology of metabolic syndrome.
The hypothesis of the proposed trials is that the regular intake of a specific diet designed for enteral nutrition of type 2 diabetic patients results into a better nutritional status. Thus, the aim of the study is to scientifically evaluate the healthy effects of the administration of an enteral complete diet for diabetic patients (T-Diet plus Diabet).
The purpose of this study is to compare the vascular permeability of blood vessel walls (of the carotid artery) in pre-menopausal women who have metabolic syndrome (syndrome of having at least 3/5 following features- increased abdominal fat, low good cholesterol (HDL-C), elevated fasting blood fats (triglycerides), elevated blood pressure, an elevated fasting glucose) versus those women who are normal weight and with normal cholesterol, blood fats, blood pressure, and blood sugar. We are using a novel technology to measure vascular permeability known as dynamic contrast enhancement magnetic resonance imaging (DCE-MRI). The primary variable is ktrans ratio which is a mathematically derived quantity obtained from DCE-MRI. We are trying to identify novel markers of early atherosclerosis in young women.
This study will examine the impact diabetes genetic counseling on patient motivation and disease prevention behaviors among subjects with pre-diabetes. Intervention subjects will be provided with their individual diabetes genotype risk score derived from aggregating the combined results of 37 diabetes risk-associated genetic loci. Controls will not be tested. All subjects will be enrolled in a 12-week diabetes prevention program.
The purpose of this study is to assess the effectiveness of two different reduced calorie diets that have different combinations of carbohydrate, fat, and protein content in 2 groups of study participants: insulin sensitive participants and insulin resistant participants. The hypothesis of the study is that people with high and low levels of insulin resistance may respond differently to different diet compositions in a real-world environment using meals that are commonly available.
