Abstract
The World Health Organization （WHO） was concerned about the effect of increased intake of free sugars on the global public health （an increase in noncommunicable diseases） and published the “Guideline： Sugars Intake for Adults and Children ” in 2015. The guideline provides recommendations on the intake of free sugars based on scientific evidence from a systematic review （SR） of obesity and dental caries.
The author confirmed the details of the SR in the original paper and had the following findings： （1） while a meta-analysis of increased sugar intake suggested a comparable weight increase, another meta-analysis of isoenergetic exchanges of free sugars with other carbohydrates showed no change in body weight; and （2） although the recommendations of the guideline are based on scientific evidence from a SR of free sugars intake and dental caries, the quality of some available evidence was considered to be very low.
The guideline is also used as a reference by Japanese nutrition policy makers. This paper explores how we dietitians can use the guideline.
