No es frecuente encontrar algo simple, factible y que también sea muy bueno para la salud, pero creo que esto sí: comer un medio puñado de frutos secos todos los días.

De acuerdo con un nuevo estudio de Holanda, sólo 10 gramos (aproximadamente un tercio de una onza) de nueces o maní (técnicamente una leguminosa) un día lleva a un menor riesgo de muerte por enfermedades respiratorias y cardiovasculares, enfermedades neurodegenerativas, la diabetes y la cáncer. No hubo beneficios de comer mantequilla de maní.

La demanda mundial de legumbres, uno de los cultivos de alimentos agrícolas más importante del mundo, es cada vez mayor; al mismo tiempo, su producción se ha visto afectada negativamente por la sequía. En un trabajo de investigación de las Universidades de Indiana, Purdue e Indianápolis, publicado hoy en la revista PLOS ONE, los investigadores proporcionan información que podría ayudar a la planificación agrícola para minimizar las pérdidas de rendimiento causadas por la sequía.

Lack of physical activity – along with unhealthy diets – are key risk factors for major non-communicable diseases such as cardiovascular diseases, cancer, and diabetes, according to the World Health Organisation (WHO).

Thirty to 70% of EU citizens are currently overweight, while 10-30% are considered obese,according to the WHO, which warned against an obesity crisis in Europe over the coming decades.

To counter the “epidemic”, the WHO recommends 150 minutes of moderate physical activity each week. This, it argues, would reduce the risk of ischaemic heart disease by approximately 30%, the risk of diabetes by 27%, and the risk of breast and colon cancer by 21–25%.
