Subject: What type of food gives the most complete nutrients that your body needs?

I am wondering- if u were isolated and were only allowed 1 type of drink 
and 1 food item, but in an unlimited supply, what kind of food and drink 
would it be that would give your body the most nutrients an allow you to 
survive the longest - I was thinking milk for the drink and potatoes for 
the food..am I close?
