Abstract

Potatoes have been a dietary staple in the US and the world for centuries. Their hardiness, economy and nutrient density render them an invaluable crop. Potatoes contribute key nutrients to the diet including vitamin C, potassium, and dietary fiber. Despite their nutrient density, their impact on human health remains somewhat controversial. Animal studies and some human research indicates that potatoes and potato nutrients may positively impact risk factors for chronic disease including blood pressure, blood lipids and inflammation. Conversely, there observational data linking potato consumption to an increased risk of weight gain and type 2 diabetes purportedly due to the potato’s high glycemic index (GI). This review provides an overview of the nutrient content of potatoes as well as a critical evaluation of the existing research examining potatoes and potato nutrients in health and disease states.

Resumen

Las papas han sido un alimento básico en los EU y en el mundo por siglos. Su resistencia, economía y densidad nutritiva la hacen un cultivo invaluable. Las papas contribuyen con nutrientes clave a la dieta, incluyendo vitamina C, potasio y fibra dietética. A pesar de su densidad nutritiva, su impacto en la salud humana permanece de alguna manera controversial. Estudios en animales y algunas investigaciones en humanos indican que las papas y sus nutrientes pudieran impactar positivamente en los factores de riesgo para enfermedades crónicas, incluyendo la presión sanguínea, su contenido de lípidos e inflamación. Por el contrario, hay datos de observación que asocian el consumo de la papa a un riesgo cada vez mayor en aumento de peso y de diabetes tipo 2, supuestamente debido al alto índice glicémico (GI) de la papa. Esta revisión proporciona una vista general del contenido nutricional de las papas, así como una evaluación crítica de la investigación existente que examina la papa y sus nutrientes en situaciones de salud y enfermedad.
