Which of these food products requires the most water for production?
- A.
  
  Chocolate (1 kg)
- B.
  
  Beef (1 kg)
- C.
  
  Cheese (1 kg)
Correct Answer
A. Chocolate (1 kg)

Explanation
Chocolate!

It requires 17196 liters of water to produce one kilo chocolate, according to a report from IME. I've had hard time finding an explanation for this. It seems to be a combination of the amount of water used in the milk production, water use in growing the cacao beans which need plenty of water and processing. Information on how different chocolates are produced and the volume of water used is hard to come by online.

Production of beef also requires a massive volume at 15415 liters, while cheese requires 3178 liters.
