Consuming too much energy – whether from fat or carbohydrates, including sugar – will make you gain weight.
If left unchecked, this excess weight increases your risk of lifestyle-related diseases such as diabetes, heart disease and some cancers.
In recognition of this, the World Health Organisation (WHO) recommends adults and children limit their intake of “free sugars” to less than 10% of their total energy intake. Below 5% is even better and carries additional health benefits.
Free sugars refer to monosaccharides (such as glucose) and disaccharides (sucrose or table sugar) added to foods and drinks by the manufacturer, cook or consumer. It also refers to sugars naturally present in honey, syrups, fruit juices and fruit juice concentrates.
How much sugar is in your favourite drinks? Post continues after video.
Free sugars are different from sugars found in whole fresh fruits and vegetables. There is no scientific evidence that consuming these sugars leads to health problems.
So the guidelines don’t apply to fresh fruit and vegetables.
If you’re an average-sized adult eating and drinking enough to maintain a healthy body weight (roughly 8,700 kilojoules per day), 10% of your total energy intake from free sugar roughly translates to no more than 54 grams, or around 12 teaspoons, per day.
But more than half of Australians (52%) usually exceed the WHO recommendations.
Most sugar we eat (around 75%) comes from processed and pre-packaged foods and drinks. The rest we add to tea, coffee and cereal, and other foods we cook.
Sugary drinks account for the largest proportion of Australians’ free sugar intake. A single can or 600ml bottle of soft drink can easily exceed the WHO recommendation, providing around 40-70g sugar. One teaspoon equates to 4.5g white sugar, so soft drinks range from 8.5 to 15.5 teaspoons.
