Dried apples enriched with mandarin juice by vacuum impregnation improve antioxidant capacity and decrease inflammation in obese children

Nutr Hosp. 2013 Jul-Aug;28(4):1177-83. doi: 10.3305/nh.2013.28.4.6580.

Abstract

Background: A favorable effect over development of degenerative diseases is derived of an adecuate intake of fruit and vegetables, mainly due to their antioxidant compounds

Objectives: The goal of this study was to test the effect in vivo over oxidant status and inflammation in obese children of a novel food product made of dried apples enriched with mandarin juice by vacuum impregnation.

Methods: A four-week intervention study was conducted in 41 obese children (> 2 standard deviation score-body mass index). Participants were instructed to follow their usual diet supplemented with 40 g/day of the developed product. Anthropometric parameters were determined including body mass index, waist circumference and estimations of body fat percentage using bioelectrical impedance. Dietary intake was assessed by questionnaire. Metabolic risk factors (blood pressure, lipid profile, glucose and insulin resistance) were recorded. To determine oxidant status, plasma total antioxidant capacity and 8-hydroxydeoxyguanosine, as marker of oxidative damage to DNA, were investigated. High-sensitive C-reactive protein, tumor necrosis factor-α, and interleukins 6 and 1-α were measured as inflammatory markers. Measurements were collected at baseline and at the end of the intervention period.

Results: Significant improvement in systolic blood pressure and lipid profile after intervention period was noted. A significant increase in the antioxidant capacity of plasma (ABTS and FRAP assays) and reductions in DNA oxidative damage and inflammatory markers were also found.

Conclusion: Overall, adding the product to the diet contributes to ameliorate oxidant and inflammatory status in obese children and several risk factors for atherosclerosis.

Antecedentes: Una adecuada ingesta de vegetales previene el desarrollo de enfermedades degenerativas, principalmente debido a sus compuestos antioxidantes. Objetivo: Evaluamos el efecto in vivo en los niños obesos de un nuevo producto alimenticio hecho de manzanas deshidratadas enriquecidas con zumo de mandarina mediante impregnación a vacío. Métodos: Estudio prospectivo longitudinal de cuatro semanas de duración. Se estudiaron 41 niños obesos que suplementaron su dieta habitual con 40 g/día del producto desarrollado. Se determinaron parámetros antropométricos (índice de masa corporal, circunferencia de la cintura) y estimación de la de grasa corporal con impedancia bioeléctrica. La ingesta dietética se evaluó por cuestionario. Se registraron factores de riesgo metabólico (presión sanguínea, perfil lipídico, glucosa y resistencia insulínica). El estado oxidante se investigó mediante la capacidad antioxidante total del plasma y la 8-hydroxideoxiguanosina (marcador de daño oxidativo al ADN) y como marcadores de inflamación valoramos la proteína C-reactiva ultrasensible, el factor de necrosis tumoral-??y las interleukinas 6 y 1-?. Las mediciones se recogieron al inicio y al final del período de intervención. Resultados: Encontramos una mejoría significativa en la presión arterial sistólica y en el perfil lipídico después del período de intervención. Igualmente demostramos un aumento significativo de la capacidad antioxidante del plasma, una reducción del daño oxidativo del ADN y de los marcadores inflamatorios. Conclusión: La adición a la dieta del producto elaborado con manzana deshidratada, y enriquecido con zumo de mandarina mediante impregnación al vacío, contribuye a mejorar el estado oxidante e inflamatorio en los niños obesos, así como diversos factores de riesgo cardiometabólico.
