Your water footprint.
Hidden benefactor of
a healthy diet.
Dietary changes can lead to big health benefits, but there are global benefits to a change in diet too. Vanham et al (2018) have found that a healthy diet results in a decrease in the water footprint required to produce the food. Whilst healthy vegetarian or pescetarian diets have the lowest water footprint, even a change to a healthy diet containing meat results in a decrease in water footprint of between 11% and 35%.
