WHO sugar guideline
WHO calls on countries to reduce sugars intake among adults and children (Guideline: Sugars intake for adults and children, 2015) — news release
Overview
World Health Organization. WHO news release 2015
WHO recommends keeping free sugars, including honey and juice sugars, below 10% of energy.
Does the study support the specific claim? No · Methodological quality: high
Plain-language summary
Study explained simply
- What did the researchers want to find out?
Recommended limit for free sugars.
- How was the study done?
International guideline (news release read in full).
- How many people, animals or samples were studied?
Not applicable; Adults and children
- What was actually found?
Free sugars <10% of total energy (strong recommendation); further reduction <5% (~25 g, 6 teaspoons) conditional. Free sugars include sugars added by manufacturer, cook or consumer and sugars naturally present in honey, syrups, fruit juices and fruit juice concentrates; not sugars in fresh fruit, vegetables or milk. A can of sugar-sweetened soda contains up to 40 g free sugars.
- How large was the observed effect?
<10% energy (strong); <5% (conditional)
- What do the results mean in everyday life?
Honey, juices and table sugar all count.
- What are the study's limitations?
Conditional recommendation for <5%
- What does it say about Elawady's specific claim?
Defines honey and juices as free sugars: contradicts C-SUG-01 and C-SUG-06; supports C-SUG-02.
- Do the results apply to Germany and Europe?
Applies globally including EU and Egypt.
- What can explicitly not be concluded from this study?
Not applicable.

15. Linked fact checks
- Sugar-sweetened soft drinks deliver liquid calories that do not satisfy hunger and therefore promote weight gain in children and adults. – Studies supporting the claim
- Soft drinks cause tooth decay. – Studies supporting the claim
- White sugar is the greatest product humans ever made; any amount of sugar per day is beneficial, and one can eat a kilogram of white sugar or honey. – Studies contradicting or limiting the claim
- Honey is chemically essentially sugar ('sugar knotted by the bee'); white sugar and honey are nutritionally similar. – Studies supporting the claim
- White sugar is not an industrial/manufactured product but an extract of plants, so it does not belong with processed foods. – Studies contradicting or limiting the claim
- Implicit in the system's lists: sugar-cane juice, canned juices, honey, jam and sweets are acceptable while sugar-sweetened soft drinks are harmful. – Studies contradicting or limiting the claim
