New guidelines from the World Health Organization are enough to kill anyone's sugar high.
The U.N. health agency says the world is eating too much sugar and people should slash their intake to just six to 12 teaspoons per day - an amount that could be exceeded with a single can of soda.
So, put down that doughnut. And while you're at it, skip the breakfast cereal, fruit juice, beer and ketchup.
The guidelines, released Wednesday, finalize draft advice first released last year and are focused on the added sugars in processed food, as well as those in honey, syrups and fruit juices.
The advice does not apply to naturally occurring sugars in fruit, vegetables and milk, since those come with essential nutrients.
"We have solid evidence that keeping intake of (added) sugars to less than 10 percent of total energy intake reduces the risk of overweight, obesity and tooth decay," Francesco Branca, director of WHO's nutrition department, said in a statement.
Experts have long railed about the dangers of sugar and studies suggest that people who eat large amounts of the sweet stuff are at higher risk of dying prematurely from heart problems, diabetes and cancer, among other conditions.
To meet the lower threshold set by the new guidelines, Americans, Europeans and others in the West would have to slash their average sugar intake by about two-thirds. Some experts said the 10 percent target was more realistic for Western countries than the lower target. They said the 5 percent of daily calories figure was aimed mostly at developing countries, where dental hygiene isn't good enough to prevent cavities, which can lead to serious health problems.
WHO had previously suggested an upper limit for sugar consumption of around 10 percent, but issued the 5 percent guidance based on the presumed additional health benefits from cutting intake even further, though it said it had no solid evidence to support that.
Sugar is just one of a number of ingredients that have come under attack, such as salt and trans fat. However, WHO pointed out that when it comes to sugar, most people don't realize how much they're eating because it's often hidden in processed foods not considered sweet.
For example, one tablespoon of ketchup has about 4 grams (1 teaspoon) of sugar and a single can of soda has up to 40 grams (10 teaspoons).
"The trouble is, we really do like sugar in a lot of things," said Kieran Clarke of the University of Oxford, who said the global taste for sugar bordered on an addiction. "Even if you are not just eating lollies and candy, you are probably eating a fair amount of sugar."
Clarke noted that there's added sugar even in pasta sauces and bran cereals. She said fruit juices and smoothies were common dietary offenders, because they have very concentrated amounts of sugar without the fiber benefits that come with eating the actual fruit.
Clarke welcomed the new WHO guidelines but said people should also consider getting more exercise to balance out their sweet tooths. "If you do enough exercise, you can eat almost anything," she said. "But it's very hard to avoid large amounts of sugar unless all you're eating is fruits and vegetables."
