Limiting added sugar intake to 100 calories/day for women and 150 calories/day for men reduces cardiovascular risk factors including dyslipidemia, hypertension, and obesity.
To support heart health, limit added sugars to about 6-8 teaspoons (100 calories) for women and 9-12 teaspoons (150 calories) for men daily. The easiest way to do this is to cut back on sugar-sweetened beverages, which are the biggest source of added sugars in the typical diet.
ModerateSupportsMEDIUM confidence
A prudent upper limit of intake is half of the discretionary calorie allowance, which for most American women is no more than 100 calories per day and for most American men is no more than 150 calories per day from added sugars.
Why this rating
Based on observational studies and metabolic trials, but the authors note trial data are limited and results are sometimes inconsistent.
