You wouldn't eat 16 teaspoons of sugar in one hit, so why would you drink them all in one go?
Did you know there are about 16 teaspoons of sugar in a 600ml bottle of regular soft drink? Or about nine teaspoons in a sports drink? Talk about having to work it off after you've already been working out! Over time all that extra sugar in sugary drinks starts to add up. If you're not burning it off, you could be drinking yourself fat, increasing your risk of type 2 diabetes, heart disease and some cancers.
So instead of grabbing a soft drink, why not try water, reduced-fat milk or unsweetened drinks instead?
