    Abstract:
    Nuts are foods with a high energy density, due in part to its small water content. They also present a low saturated fat content (<7%) but a high unsaturated fat contribution (40-60%). They represent one of the richest sources of dietary fiber, which is basically of the insoluble type. The effects of nut intake on health have been widely studied. Several prospective epidemiological studies performed on large cohorts have consistently shown that regular consumption of small amounts of nuts is negatively related to the risk of cardiovascular disease and to the risk of cardiovascular or all-cause mortality. From these studies can be concluded that regular consumption of small amounts of nuts leads to a 30-50% reduction in the risk of cardiovascular disease. Additionally, intervention studies have shown a positive effect of nut intake on lipid profile with significant reductions in total and LDL cholesterol levels and small or null effects on the HDL fraction. More recently, some studies have focused on the effect of nuts on body weight. At present, no evidences support a detrimental effect of nut consumption on body weight. On the contrary some weight loss studies suggest a beneficial effect of nut intake on body weight regulation.

Los frutos secos son alimentos caracterizados por una alta densidad energética debida en parte a su escaso contenido hídrico. Además, presentan un bajo contenido en grasa saturada (<7%) y un elevado aporte de grasa insaturada (40-60%). Constituyen también una de las fuentes más ricas de fibra dietética, fundamentalmente insoluble. Se ha estudiado ampliamente cuales son los efectos que la ingestión de frutos secos tiene sobre la salud. Diversos estudios epidemiológicos prospectivos realizados sobre amplias cohortes han mostrado consistentemente una relación negativa entre el consumo regular de pequeñas cantidades de frutos secos y el riesgo de enfermedad cardiovascular o el riesgo de mortalidad de origen cardiovascular y de mortalidad por todas las causas. El análisis de estos estudios refleja que el consumo regular de pequeñas cantidades de frutos secos reduce el riesgo de enfermedad cardiovascular en un 30-50%. Los estudios de intervención demuestran que la toma regular de suplementos de frutos secos mejora el perfil lipídico, reduciendo significativamente los niveles de colesterol total y colesterol LDL con escaso o nulo efectos sobre las HDL. El efecto de los frutos secos sobre el peso corporal ha sido también recientemente estudiado. Hasta el momento no existen evidencias de un aumento de peso corporal asociado al consumo de estos alimentos, y, sin embargo, algunos estudios de pérdida ponderal sugieren un posible efecto beneficioso en la regulación del peso corporal.
