Blue leaf: Una alternativa diferente de alimentación saludable

Blue Leaf es un proyecto de emprendimiento que consiste en la elaboración y venta directa de bebidas naturales a base de frutas a través de un food truck en la ciudad de Bogotá. Tras revisar algunas tendencias actuales como la cultura Fitness y el Juicing, y tras identificar un problema sobre los hábitos de alimentación desordenados que llevan muchas personas, nace Blue Leaf como una alternativa de alimentación saludable, natural, práctica y diferente. El negocio contará inicialmente con un portafolio de 12 bebidas divididas en tres categorías. Primero, las bebidas alimenticias cuentan con altos contenidos nutricionales y sirven como fuente de alimento práctico y saludable; segundo, las bebidas funcionales, están diseñadas para ofrecer beneficios específicos de salud como desintoxicar, ayudar a bajar de peso o fortalecer las defensas; por último, las bebidas fuente de energía, cuentan con altos niveles de vitaminas y minerales que le permiten a los consumidores recargar energías rápidamente y continuar con sus actividades diarias. Adicionalmente, Blue Leaf ofrecerá la oportunidad a los consumidores de hacer su propia bebida, dándoles la posibilidad de elegir de entre más de 50 ingredientes entre bases, frutas, verduras, hierbas, semillas, adiciones y endulzantes. El proyecto es liderado por Paola Higuera Rodríguez y David Santiago Soto, ambos estudiantes de la Escuela de Administración de la Universidad del Rosario

Effects of chronic and acute consumption of fruit- and vegetable-puree-based drinks on vasodilation, risk factors for CVD and the response as a result of the eNOS G298T polymorphism

The average UK adult consumes less than three portions of fruit and vegetables daily, despite evidence to suggest that consuming five portions daily could help prevent chronic diseases. It is recommended that fruit juice should only count as one of these portions, as juicing removes fibre and releases sugars. However, fruit juices contain beneficial compounds such as vitamin C and flavonoids and could be a useful source of dietary phytochemicals. Two randomised controlled cross-over intervention studies investigating the effects of chronic and acute consumption of commercially-available fruit- and vegetable-puree-based drinks (FVPD) on bioavailability, antioxidant status and CVD risk factors are described. Blood and urine samples were collected during both studies and vascular tone was measured using laser Doppler imaging. In the chronic intervention study FVPD consumption was found to significantly increase dietary carotenoids (P = 0.001) and vitamin C (P = 0.003). Plasma carotenoids were increased (P = 0.001), but the increase in plasma vitamin C was not significant. There were no significant effects on oxidative stress, antioxidant status and other CVD risk factors. In the acute intervention study FVPD were found to increase total plasma nitrate and nitrite (P = 0.001) and plasma vitamin C (P = 0.002). There was no effect on plasma lipids or uric acid, but there was a lower glucose and insulin peak concentration after consumption of the FVPD compared with the sugar-matched control. There was a trend towards increased vasodilation following both chronic and acute FVPD consumption. All volunteers were retrospectively genotyped for the eNOS G298T polymorphism and the effect of genotype on the measurements is discussed. Overall, there was a non-significant trend towards increased endothelium-dependent vasodilation following both acute and chronic FVPD consumption. However, there was a significant time x treatment effect (P < 0.05) of acute FVPD consumption in individuals with the GG variant of the eNOS gene.
