How much sugar per day, by the evidence

What people ask us next.

Q01

How much sugar should I eat per day?

The US Dietary Guidelines cap added sugar at under 10% of daily calories, about 50 g on a 2,000-calorie diet. The American Heart Association sets a tighter target of 25 g/day for women and 36 g/day for men (Johnson et al. 2009). These limits apply to added sugar only, not the sugar naturally in whole fruit, plain milk, or vegetables. The average US adult takes in ~68 g/day, so most people are well over both numbers.

Q02

Does the sugar in fruit count toward the daily limit?

No. The limits apply to added sugar, not to the sugar naturally present in whole fruit, plain dairy, and vegetables. That natural sugar arrives with fiber, water, and micronutrients that slow its absorption and increase fullness, and whole-fruit intake is linked to lower disease risk in prospective studies. The exception is fruit juice, which removes the fiber and behaves more like a sweetened drink, so guidelines treat it with more caution than whole fruit.

Q03

Is 50 grams of sugar a day too much?

50 g of added sugar is exactly the US Dietary Guidelines ceiling of under 10% of a 2,000-calorie diet, so it is the upper bound rather than a healthy target. It is above the American Heart Association's tighter limits of 25 g for women and 36 g for men. If the 50 g comes mostly from sweetened drinks and processed food, most nutrition guidance would consider it high; the AHA numbers are the better everyday goal.

Q04

How much sugar per day to lose weight?

There is no separate weight-loss sugar number; cutting added sugar toward the AHA targets of 25 g (women) and 36 g (men) supports weight loss mainly by removing empty liquid calories. Sugar-sweetened drinks add calories without satiety, so cutting them tends to lower total intake without deliberate restriction. The lever is reducing added-sugar calories that do not make you full, especially from beverages, rather than eliminating sugar entirely.

Q05

What is the difference between total sugar and added sugar on a label?

Total Sugars includes all sugar in the food, both natural (fruit, dairy) and added. Added Sugars, the indented line the FDA has required since 2020, counts only the sugar put in during processing. This is why plain yogurt or a fruit product can show high Total Sugars but zero or low Added Sugars. Read the Added Sugars line and its %DV, which is based on the 50 g/day value, to judge a product.

Q06

Is natural sugar like honey or maple syrup better than white sugar?

Not meaningfully, for the daily limit. Honey, maple syrup, agave, and cane juice all count as added sugar and are metabolized similarly to table sugar, so they count against the 25-50 g target the same way. They carry trace minerals, but in amounts too small to change the calculus. The useful distinction is added versus naturally occurring, not 'natural' versus refined; for how to weigh claims like these, see our method for evaluating a food claim.
