Macro partitioning
In Japanese women, high starch intake is not significantly associated with mortality, but high free sugar intake is positively associated with total and non-cancer/non-cardiovascular mortality.
For Japanese women, reducing free sugar intake is associated with lower mortality risk, while starch intake (like rice) does not appear to increase mortality risk. Focus on minimizing free sugars rather than restricting starch.
GoodQualifiesMEDIUM confidence
In women, there was no significant association between any type of carbohydrates and mortality except that intake of free sugars was significantly positively associated with total and non-cancer, non-cardiovascular mortality.
Why this rating
Same cohort strength as N1, but the effect is weaker (only free sugars significant) and specific to women.
