Background: Abdominal obesity is an important feature of the metabolic syndrome, along with cardiometabolic risk factors that are associated with the consumption of energetic foods with low nutritional value. Orange juice is a high nutritional density beverage, with moderate energy level per portion (110 kcal / 250 mL), which contribute with significant levels of vitamins, minerals, and citrus flavonoids in the diet. Objectives: To evaluate the effect of regular consumption of 100% orange juice associated with a balanced diet on abdominal obesity and other anthropometric parameters in individuals with metabolic syndrome. METHODS: It was a parallel, controlled and randomized study with 70 patients previously diagnosticated with metabolic syndrome, according to the ATPIII and AHA/NHLA criteria, which were oriented for a balanced diet keeping, suffice energy to maintain the current weight for 12 weeks. Patients were allocated into two groups: (1) Control (n = 35): only dietary guidance; and (2) Orange juice (n = 35): dietary guidance plus 100% orange juice (500 mL/day). Body composition measurements were performed by high-frequency tetrapolar bioimpedance (Inbody 720®). Food Records assessed dietary intake weekly during the intervention. Results: All subjects reduced body weight (2%), BMI (2.3%), waist circumference (5.5%), hip circumference (4%), waist-hip ratio (2%), visceral fat área (4.5%) and body fat mass (5.3%) (p <0.05), with no change in muscle mass (p> 0.05). Both groups lowered energy and macronutrient intakes, but vitamin C was increased by 157% (p <0.01) only in the orange juice group. Conclusions: Regular consumption of orange juice consistent with a balance diet was able to reduce anthropometric parameters associated with metabolic syndrome. In addition, the regular intake of orange juice have improved the diet quality supplying higher amounts of vitamin C and folic acid, and therefore may be an effective nutritional strategy for these patients.
