Filter by:Epidemiological evidence is accumulating that a high consumption of added sugars is associated with metabolic diseases such as non-alcoholic fatty liver disease and type 2 diabetes. Fructose, one of the principal added sugars, is believed to be the most disadvantageous sugar. Data from a large population-based cohort demonstrated that fructose intake from fruit juice and sugar-sweetened beverages, but not whole fruits, is associated with higher intrahepatic lipid content. A study in mice demonstrated that fast fructose exposure resulted in higher intrahepatic lipid content than slow fructose exposure. The food matrix, i.e. the complex spatial organisation of and interactions between nutrients, may account for the fast versus slow fructose exposure and subsequent health consequences. Therefore the investigators aim to investigate the role of the fructose matrices on serum fructose peaks. The investigators hypothesize that liquid fructose matrices will cause higher serum fructose peaks in comparison to solid fructose matrices. Objective: To quantify serum fructose peaks within 150 minutes following intake of fructose-containing matrices.
Cardiometabolic diseases have been associated with high consumption of sweetened beverages. These products are responsible for the largest portion of the total consumption of fructose in the diet and it is suggested that excessive intake of this monosaccharide may contribute to the development of risk factors for these diseases due to differences in metabolism relative to glucose. However, there is a lack of data in the literature demonstrating the deleterious effects of excessive fructose consumption on vasodilation and whether aerobic training may be able to prevent or mitigate these damages in humans. Therefore, the aim of the study will be to verify the effect of 4 weeks of high fructose diet associated with aerobic training on uric acid levels and its influence on markers related to oxidative stress and vasodilatation. Twenty-one sedentary men and women, aged between 19 and 35 years, will be submitted to 4 weeks of intervention. In a randomized way, subjects will be divided into 3 groups: high fructose diet, high glucose diet and high fructose diet and exercise. Blood samples will be taken before, in the middle and after the intervention to verify the concentrations of uric acid, superoxide dismutase enzyme, thiobarbituric acid, nitrite / nitrate, lipid profile, glucose, insulin, C-reactive protein and endothelin-1. In addition, flow-mediated dilatation, insulin resistance index, pancreatic beta cell functional capacity index, oral glucose tolerance test, 24-hour blood pressure, heart rate variability and body composition will be analyzed. The comparisons will be performed through the Generalized Estimates of Equations, adopting the factors group and time. The Bonferroni post-hoc will be used to identify differences. The accepted level of significance will be 5%.
Diabetes is one of the most common and chronic diseases in the world, with the prevalence and incidence of this disease rising in most societies, especially in Iran. Suitable treatments for type 2 diabetes include changing lifestyle with exercise, nutrition, and drug use. New research suggests that added sugar, especially fructose, is the main trigger for diabetes and pre-diabetes even more potent than other carbohydrates. Fructose has a low glycemic index (23μg =) and slowly increases blood glucose levels. Therefore, it is thought that replacing fructose instead of glucose can have a positive effect on glycemic control of diabetic patients..
