Conventional wisdom suggests that we should drink at least 8 glasses of water a day, or about 1.5 – 2L. How much water do you drink a day?
For a lot of people, even drinking a litre of water a day is tricky. When I first my husband, he didn’t drink any water, but insisted that his 8 cups of milky, English Breakfast tea met his daily water requirement. I took me a while to convince him that tea is a diuretic 😳.
One thing to consider is that if you’re already eating a good portion of fruit and vegetables a day, you’ll also be getting the water in the produce, along with the fibre, micro and macronutrients too.
Some fruit and veg contain more water than others.
For example, 1 medium sized apple contains 86% water, whilst a slice of watermelon (the clue’s in the name!) is 97% water. Courgette, radish and celery are 95% water and cauliflower, peppers and spinach are 92% water. To contrast, a banana contains 74% water.
So if you’re eating 7 to 10 portions of fruit and veg a day, do you also need to be drinking 8 glasses of water a day?
As ever, it’s important to consider how you feel on an individual level and listen to what your body is telling you.
In general, if your pee isn’t clear or a light straw colour, then you probably need to up your water intake either through food or water itself. If you’re eating lots of fruit and veg that are high in water content and you’re still thirsty with dark pee, then you probably need to up your water intake. If you’re very active or outside on a hot day, it’s probably worth increasing your water intake.
Just as you can drink too little water and end up dehydrated, you can also drink too much water and end up with something called hyponatremia, where the cells become completely waterlogged, throwing the sodium-potassium balance in the cells off, which can be fatal. So the moral of the story: observe your body’s signs, consider how much fruit and veg you eat a day and tailor your water consumption to your own lifestyle and thirst.
And a note of caution: excess thirst can be a sign of diabetes, so if you’re experiencing this, I highly recommend going to see your GP.
