Limit sugar intake to 25 grams a day to stay healthy: UN

However, the organization also recommended that consuming no more than 10 percent calories from sugary substance, or roughly 50 grams of sugar for the average person was also feasible, the Mashable reported.

WHO expert panels have been tentatively suggesting the 10 percent sugar limit since 1989, and the current guidelines have been in a period of consultation for the past year. But for the first time, this WHO advisory went further in suggesting cuts to the amount of sweetness in people's life.

The organization did not count the sugars naturally present in regular old fruit or milk. But it had counted fruit juices and honey, no matter how natural.

There are slightly less than 25 grams of sugar in half a can of soda. Most yogurts contain around 24 grams per container. People can hit the WHO's suggested daily limit using foods they wouldn't even suspect, such as ketchup, which has about four grams in a single-serving dollop.

The Sugar Association slammed the new recommendations, not surprisingly. But even some neutral experts seemed incensed at the lower limit and the effect it might have on one's daily diet.

The study is published in the Journal of the American Medical Association.
