There’s no denying that water is good for you, but does everyone really need to drink 8 cups or more every day? For people who have specific health concerns, such as kidney stones or a tendency to develop urinary tract infections, drinking lots of water can be beneficial. There is however, no scientific evidence that healthy people need to drink large quantities of water. So how much water should you drink?
The recommendation for older people is to drink at least eight cups of fluid each day. Water is a good choice because it is calorie-free, cheap and readily available but other fluids including milk, fruit juice, tea, coffee, soup, custard etc can make up the 8 cups. In addition, many “solid” foods contain appreciable amounts of water. For example, many fruits and vegetables are 90 percent or more water by weight.
How do you know if are you are having enough fluids?
The easiest way to tell is to check the colour and volume of your urine. Except first thing in the morning, your urine should be almost clear and there should be plenty of it. If you have dark yellow urine you are not drinking enough.
