H2-Whoa! How much water is in a day of food?

Food PyramidHow much water is on your plate? About 70 percent of the world's "blue water withdrawals" irrigate agriculture. World Water Day is March 22, and this year's theme examines food production. To see how many gallons of water bring common foods from field to plate, take our H2-Whoa! quiz. 

Q: How much water does it take to produce one person's daily food?

A) About 530 to 1,320 gallons.

B) Depends on the location.

C) These saltines are so dry there is no way water went into their production. 


A: Both A and B. It takes about 530 to 1,320 gallons for one person's daily food, but this number could vary depending on the climate and agricultural practices of the consumer's location. 

To lose the water weight in your diet, save (and eat!) leftovers or prepare smaller meals. About 30 percent of the food produced worldwide is never eaten. Avoid throwing out food and you'll ultimately avoid wasting water.
