Question: how many litres of water should we drink per day according to dieticians to stay healthy?
Answer: As a rough guideline, the Dieticians of Canada suggest 2.2 litres (nine cups) per day for women and three litres (12 cups) for men. These totals include food moisture, which accounts for about one-fifth of the average person's liquid intake-and more for people who eat a lot of fruit and veggies.
