Sugary drinks taste great. After all, who doesn't like something sweet to drink at the end of a meal, or at any point during the day? But the truth is that sugary drinks cause more harm than good – not only to your teeth, but to your overall health as well. Even the World Health Organisation recommends sugar intake of below 10 percent of total energy intake. WHO recommends a further reduction to 5 percent, or 6 teaspoons per day, for maximum health benefits.
