Four puree formulations, guava-strawberry (GSP), guava-blackberry (GBP), guava-soursop (GSSP) and guava-passion fruit (GPP) purees, were donated by Purés y Derivados de Nayarit (PDN), Camichin de Jauja, Nayarit, Mexico. The elaboration, characteristics, nutritional composition and content of bioactive compounds of the purees were described in a previous publication (Pérez-Beltrán et al., 2017). 2.2 Experimental diets Six diets were used. A commercial pedestrian maintenance diet for experimentation (Nutri cubo Purina  ; Agribands Purina Mexico SA de CV., Mexico City, Mexico) was considered as the standard rodent diet (StD). Dther diet was a high-fat diet

Fruit purees can be added to diet as alternative sources of bioactive compounds for the prevention and/or improvement of the complications of metabolic syndrome. In this work we evaluated the effect of the intake of low-fat diets enriched with fruit purees (guava-strawberry, guava-blackberry, guava-soursop, guava-passion fruit) on the body weight and biochemical markers in metabolic syndrome analogy (MSA)-induced rats. The rats (n=6 for each treatment) were induced with a high fat diet and were injected with streptozotocin, one dose every week for 4 consecutive weeks after fasting overnight, then healthy rats were fed with standard diet and MS rats were fed with standard diet plus each of the fruit puree, for 4 weeks. As novel findings, the diet enriched with fruit purees was associated with a reduction in body weight (~13-21 %) and a control in the metabolism of glucose by decreasing plasma glucose (~59-63 %). Also, there was a reduction in the total cholesterol, triacylglycerols, low-density lipoproteins, and low enzymatic activities of alanine aminotransferase, alkaline phosphatase and γ-glutamyl transferase, useful metabolites in the control of inflammatory processes in the liver. A notable improvement in the liver morphology was observed indicating that the treatments had a hepatoprotective effect. The diet enriched with guava-blackberry puree caused the best results on most biochemical markers of MS rats. Therefore, diets enriched with fruit purees can be an alternative for MS individuals for the control and improvement of the complications caused by this syndrome.
