Visualice la nutrición en términos de valores diarios recomendados

Wolfram Knowledgebase no sólo incluye propiedades detalladas e información nutricional para más de 37.000 "Food" y 1000 "FoodType" entidades, sino también datos de los valores diarios recomendados para 175 nutrientes. Juntos, estos conjuntos de datos extensivos permiten explorar computacionalmente el contenido nutricional de virtualmente cualquier comida, luego de forma intuitiva visualizarlos usando un simple gráfico.

In[1]:=

EntityValue["Nutrient", "EntityCount"]

Out[1]=

Recupere una lista de valores diarios recomendados de nutrientes con base en una dieta de 2000 calorías diarias.

In[2]:=

allDailyValues = Append[DeleteMissing[ EntityValue["Nutrient", "DailyValue", "EntityAssociation"]], Entity["Nutrient", "Energy"] -> Quantity[2000, ("LargeCalories")/("Days")]]*Quantity[1, "Days"]

Out[2]=
