The Study
Current WHO recommendation to reduce free sugar intake from all sources to below 10% of daily energy intake for supporting overall health is not well supported by available evidence
This study is like a teacher summarizing what other kids have said about candy — some say it makes you fat, others say it doesn’t. The teacher doesn’t do any experiments, just talks about what others found and says, 'We’re not sure.' So we can’t say candy definitely causes problems — just that people disagree.
Analysis score
Maximum 5 for a narrative review.
Where the score came from
Sugar in soda might hurt your health, but sugar in cookies or fruit doesn't seem to cause the same problems — at least not at normal amounts. Too little sugar might also make your diet less healthy.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — most people eat sugar in solid foods, not just drinks.
- 2This suggests cutting all sugar in foods may not help and could make diets worse.
- 3Sugar in drinks (SSBs) linked to weight gain; sugar in solid foods not linked.
- 4Animal studies used 50%+ sugar — way more than humans eat.
- 5Very low sugar (<5% of calories) may hurt nutrition too.
