The different sugars are broken down and used in different ways but the body doesn’t distinguish between sugars used in manufacturing or in the kitchen, and those sugars found naturally in fruits and vegetables. For example, sucrose in an apple is broken down in exactly the same way as the sucrose in your sugar bowl.

The World Health Organization recommends that adults and children reduce their daily intake of free sugars* to less than 10% of their total energy intake. It advises that a further reduction to below 5% or roughly 25 grams (6 teaspoons) per day would provide additional health benefits (1).

*Free sugars are all sugars added to foods or drinks by the manufacturer, cook or consumer, as well as sugars naturally present in honey, syrups, fruit juices and fruit juice concentrates.
