Abstract
RATS allowed food and water ad lib. show a circadian rhythm of drinking and a close association of water intake with eating. One estimate of the proportion of total water taken at night is 78%1. Meals apparently influence the timing and the amount of water drunk. About 57% of the total drinking occurs within 20 min of meals2. A meal introduces solutes into the blood and shifts water from the body fluids into the gut. To compensate for this, between 1 and 1.5 ml. of water would need to be drunk for each gram of food eaten3. Water requirements over a longer term are also determined by the diet4, because of obligatory renal water losses occasioned by solutes from the food.
