Reducing consumption of sugar-sweetened beverages to reduce the risk of unhealthy weight gain in adults

Overweight and obesity are major risk factors for a number of noncommunicable diseases, including diabetes, cardiovascular diseases and certain types of cancer. Once considered a problem only in high income countries, overweight and obesity are now dramatically on the rise in low- and middle-income countries, particularly in urban settings.

Sugar-sweetened beverage consumption is high in many parts of the world and is suggestive of poor dietary quality, as sugar-sweetened beverages contain sugars such as sucrose or fructose, often in large amounts, which contribute to the overall energy density of diets. The calories provided by sugar-sweetened beverages have little nutritional value and may not provide the same feeling of fullness that solid food provides. As a result, total energy intake may increase which can lead to unhealthy weight gain.

WHO has developed guidance on free sugars* intake, as shown below, based on the impact of free sugars intake on weight gain and dental caries. Current evidence suggests that increasing consumption of sugar-sweetened beverages is associated with weight gain. Therefore, reducing consumption of sugar-sweetened beverages would also reduce the risk of unhealthy weight gain in adults.

* Free sugars include monosaccharides and disaccharides added to foods and beverages by the manufacturer, cook or consumer, and sugars naturally present in honey, syrups, fruit juices and fruit juice concentrates.

WHO recommendations

WHO recommends a reduced intake of free sugars throughout the lifecourse.

In both adults and children, WHO recommends reducing the intake of free sugars to less than 10% of total energy intake.

WHO suggests a further reduction of the intake of free sugars to below 5% of total energy intake.
