Safflower Oil (Carthamus tinctorius L.) Intake Increases Total Cholesterol and LDL-cholesterol Levels in an Experimental Model of Metabolic Syndrome

Abstract Background: Overweight has been considered an important public health problem. To reverse this situation, various types of treatment are proposed. The safflower oil (Carthamus tinctorius L.) has been used in the prevention/treatment of obesity. Objectives: The aim of this study was to evaluate the therapeutic effects of this oil in an experimental model of metabolic syndrome. Methods: Male Wistar rats initially received a highly palatable (HP) diet for ten weeks for validation of a metabolic syndrome model. Following confirmation, the animals were treated with a HP diet and soybean oil (HPSO) or safflower oil (HPSA) supplementation (1.0 mL/1000 g of animal weight). At the end of the experiment, the body composition, lipid profile and blood glucose levels of the animals were assessed. Student t test was used for statistical analysis. Results: In the first stage (induction of metabolic syndrome), the animals given the HP diet showed gain weight (p
