If you’re looking to cut back on the amount of water you’re consuming, one of the first places you should be looking is your grocery list! Taking shorter showers and using a dishwasher definitely helps reduce your consumption, but most of our water use actually goes toward making our food!
Animal products such as meats and dairy, and other crops such as nuts have the highest water consumption for the amount of food produced. Reducing your intake of these kinds of foods can go a long way to helping reduce your personal water use. These foods are also quite high in fat, so there’s an added bonus to reducing consumption!
Unfortunately, chocolate also has a very high water footprint, so it’s a good idea to stop binge eating chocolate during every holiday (or weekend :P)!
Food to increase include fruits and vegetables, sugar crops (with moderation!) and starchy roots such as potatoes! These foods have the lowest water use and therefore have a much lower footprint on the earth.
Pulses, cereals, and oils hang out in the middle of the spectrum. Their water consumption isn’t terrible, but it’s definitely higher than the fruits and vegetables.
So if you’re looking to lessen your impact on the environment, try starting at the grocery store! You’ll also notice a cheaper grocery bill as the foods high in water use come with a higher price tag!
