how much liquid should a human drink each day
The recommendation stated that a person should have 1 ml (about 1/5 of a teaspoon) of water for each calorie he or she consumes. The average diet at the time was approximately 1900 calories, meaning you needed about 64 ounces of water per day. Now the Institute of Medicine sets general guidelines for total water intake. It recommends that women consume a total of 91 ounces (thatâs about 2.7 liters) per day â from all food and beverages combined. For men, itâs about 125 ounces a day (or 3.7 liters). Depending on your diet, about 25% of the water you consume comes from your food. Most of us healthy folks get enough water in the foods and liquids we consume. That includes any liquid we drink â even caffeinated beverages like soda, coffee and tea.
