The World Health Organization (click here) recommends consuming less than 50 grams of sugar a day for the sake of preventing obesity and tooth decay.
The ‘50 gram’ amount is equal to 12 teaspoons of sugar. If that sounds like a lot, bear in mind that a single can of soda already contains around 10 teaspoons.
The WTO recommendations that this limit include all types of free sugars such as glucose, fructose, table sugar added to processed foods and drinks and those naturally present in fruit juices, honey and syrup.
