建立食品营养标签

版本 11 引入了近 40,000 种食品的详细营养数据及其他信息. 可以直接查询个别食品的 500 多种可能属性，包括以编程方式生成营养标签.

随机选择一个食品实体.

In[1]:=

food = RandomEntity["Food"]

Out[1]=

获取关于该食品的一些属性.

In[2]:=

EntityValue[food, {"Image", "Name", EntityProperty["Food", "VitaminAContentPerServing"], EntityProperty["Food", "VitaminB12ContentPerServing"], EntityProperty["Food", "VitaminB6ContentPerServing"], EntityProperty["Food", "VitaminCContentPerServing"]}, "PropertyAssociation"]

Out[2]=

创建一杯橙汁的营养标签.
