Modifying diets by a few grams could significantly reduce groundwater use in India, says a new study. These changes include reducing the consumption of wheat and poultry, increasing the consumption of vegetables and legumes and switching to fruits like melon, oranges and papaya. <br/><br/>The new study published in the first issue of The Lancet Planetary Health says these foods have lower water requirements in production.<br/><br/>The lead author of the study, James Milner said the study is the first to investigate the potential of changing diets as a solution to decreasing freshwater availability. <br/><br/>Modifying the average diet to increase fruit consumption by 51.5 gm per day and vegetable consumption by 17.5 gm per day, along with a reduction in the consumption of poultry of 6.8 gm per day could lead to a 30 per cent reduction in freshwater use and a 13 per cent reduction in dietary greenhouse gas emissions, the study found.
