What is the source of all that added sugar? It’s really quite simple: the largest sources are sugar-sweetened beverages, snacks and sweets – as you can see in this nice graphic. If you avoid all that you’ll probably stay under the five percent level.
The new guidelines for Americans recommend no more than ten percent of calories from added sugar. And 70% of people in the US eat more than that. The WHO even recommends below five percent added sugars – not many people manage that today.
