WHO Guidelines: Sugars Intake for Adults and Children
Evidence-based recommendations for reducing free sugars consumption to less than 10% of total energy intake, with conditional guidance for further reduction to below 5%
About
The World Health Organization's comprehensive guideline on sugars intake provides critical evidence-based recommendations to combat the global rise of noncommunicable diseases (NCDs). Published in 2015, this landmark document addresses the growing concern over free sugars consumption and its association with obesity, dental caries, and other health complications that contribute to the 38 million annual NCD-related deaths worldwide.
The WHO strongly recommends that both adults and children reduce their intake of free sugars to less than 10% of their total daily energy intake. Free sugars include monosaccharides and disaccharides added to foods and beverages by manufacturers, cooks, or consumers, as well as sugars naturally present in honey, syrups, fruit juices, and fruit juice concentrates. The guidelines go further with a conditional recommendation to limit free sugars intake to below 5% of total energy intake for additional health benefits.
These recommendations are based on systematic reviews and meta-analyses of randomized controlled trials and observational studies. The evidence shows a clear association between reduced free sugars intake and decreased body weight in adults, with moderate quality evidence supporting this relationship. For dental health, the research demonstrates that higher free sugars consumption significantly increases the risk of dental caries across all age groups, with particularly strong evidence when intake exceeds 10% of total energy.
The guidelines emphasize that countries with already low free sugars intake should not increase consumption levels, as higher intakes threaten dietary quality by providing energy without essential nutrients. Implementation strategies include consumer education, food labeling improvements, marketing regulations for high-sugar products, and fiscal policies targeting sugar-sweetened beverages. These evidence-based recommendations serve as a crucial tool for policymakers, healthcare providers, and public health officials working to reduce the global burden of diet-related diseases and improve population health outcomes through targeted nutrition interventions.
