Keeping in mind that the water footprint of you food is only a part of the environmental impact of your diet --land use, fertilizer use and whether those are chemical or organic, how far and by what method your food is shipped, social considerations regarding land use are all also components--here's how much water your food consumes: Note: In general these figures have been derived from work done by Waterfootprint.org and represent gallons of water consumed per pound of food (except for beverages, whose volumes are listed). They represent global averages, not specific conditions in any one place. Fruits, Vegetables & Grains Samira Sharezay / EyeEm / Getty Images If you want to really reduce the water footprint of your food then eating a diet where fruits, veggies and grains for the vast majority of your calories is clearly the way to go--it also happens to be healthier, cheaper and better for carbon emissions, by the way. But even here there are some big variations: Lettuce -- 15 gallons;Tomatoes -- 22 gallons;Cabbage -- 24 gallons;Cucumber -- 28 gallons;Potatoes -- 30 gallons;Oranges -- 55 gallons;Apples -- 83 gallons;Bananas -- 102 gallons;Corn -- 107 gallons;Peaches or Nectarines -- 142 gallons;Wheat Bread -- 154 gallons;Mango -- 190 gallons;Avocado -- 220 gallons;Tofu -- 244 gallons;Groundnuts -- 368 gallons;Rice -- 403 gallons;Olives -- 522 gallons;Chocolate -- 2847 gallons; (One pound of chocolate being quite a serving of chocolate...)

If you want to reduce the water footprint of your diet, this is where you want to really cut back: Eggs -- 573 gallons;Chicken -- 815 gallons;Cheese -- 896 gallons;Pork -- 1630 gallons;Butter -- 2044 gallons;Beef -- 2500-5000 gallons; (Global figures for the water intensity of beef vary so significantly that an average isn't particularly informative, so a range of figures is given) Beverages Hero Images / Getty Images You want something to drink and keep your water footprint as low as possible? Tap water is probably the best thing, but even the most hair-shirt person wants some variety, so here is how the water footprint of some beverages breaks down: Tea (8oz) -- 7 gallons;Beer, barley (8oz) -- 36 gallons;Coffee (8oz) -- 29 gallons;Wine (8oz) -- 58 gallons; View Article Sources Hoekstra, Arjen Y. “The Water Footprint of Food.” Water Footprint Network.
