Women should have no more than 25 grams of added sugar per day, which works out to about 6 teaspoons. That’s the recommendation from the American Heart Association, and it’s stricter than the broader U.S. government guideline, which caps added sugar at 10% of total daily calories (about 50 grams on a 2,000-calorie diet). Both numbers refer specifically to added sugars, not the sugars naturally found in whole fruit, vegetables, or plain milk.
Why Two Different Numbers Exist
The gap between 25 grams and 50 grams can be confusing. The U.S. Dietary Guidelines set 50 grams (10% of a 2,000-calorie diet) as the upper boundary for the general population. The American Heart Association goes further, recommending women stay at or below 25 grams for heart health specifically. The World Health Organization lands in a similar place: its baseline recommendation is less than 10% of total calories, with a conditional recommendation to aim for less than 5%, or roughly 25 grams, for additional health benefits.
If you eat fewer than 2,000 calories a day, the 10% guideline shrinks proportionally. A woman eating 1,600 calories would hit 10% at just 40 grams. In practice, 25 grams is a solid target regardless of your calorie level.
Added Sugar vs. Natural Sugar
These limits apply only to added sugars, meaning sugars introduced during food processing, cooking, or at the table. This category also includes honey, syrups, and sugars from concentrated fruit juices. The sugar in a whole apple or a glass of plain milk doesn’t count toward the limit. Those naturally occurring sugars come packaged with fiber, vitamins, and minerals that slow absorption and provide nutritional value.
The distinction matters because your body processes them differently. Whole fruit delivers sugar inside intact cell walls along with fiber, which slows digestion. A glass of apple juice, by contrast, counts as added sugar under most guidelines because the fiber has been removed and the sugar is concentrated.
What 25 Grams Actually Looks Like
A single 12-ounce can of regular soda contains about 42 grams of added sugar, roughly 10 teaspoons. That alone exceeds the daily limit by nearly 70%. To put 25 grams in perspective, here’s how quickly common foods add up:
- Flavored yogurt (single-serve cup): 12 to 19 grams
- Granola bar: 8 to 12 grams
- Tablespoon of ketchup: about 4 grams
- Sweetened iced tea (16 oz): 30 to 40 grams
A quick conversion trick: divide the grams on any nutrition label by four to get teaspoons. A product listing 16 grams of added sugar contains 4 teaspoons. That visual can be more useful than the number alone.
How to Read the Label
Current FDA nutrition labels list both “Total Sugars” and “Added Sugars” as separate lines, with added sugars indented underneath. Total sugars includes naturally occurring sugars plus any added sugars in the product, so it will always be equal to or higher than the added sugars number. There is no recommended daily value for total sugars. The percent daily value you see next to added sugars on the label is based on 50 grams per day (the government’s 10% guideline), so if you’re aiming for 25 grams, you’d want to mentally double that percentage.
Health Risks of Excess Sugar
Too much added sugar doesn’t just contribute to weight gain. It raises blood pressure, increases chronic inflammation, and promotes fat accumulation in the liver. Over time, that sequence can develop into fatty liver disease, which itself raises the risk of type 2 diabetes. All of these pathways converge on cardiovascular disease: higher rates of heart attack and stroke are consistently linked to diets high in added sugars.
Harvard Health Publishing notes that many people are surprised to learn how directly sugar intake affects heart health, since the conversation around sugar tends to focus on weight and diabetes. But research has found that eating higher amounts of added sugars, including sugars from honey and fruit juice, is tied to elevated risks of both heart disease and stroke, independent of body weight. Dental health is the other major concern. Excessive sugar feeds bacteria in the mouth that produce acid, leading to cavities.
Sugar During Pregnancy and Breastfeeding
There isn’t a separate, higher sugar allowance for pregnancy or breastfeeding. Australian government dietary guidelines recommend that pregnant and breastfeeding women continue to limit foods high in added sugars, both for their own health and to support appropriate weight gain during pregnancy. Excess sugar increases calorie intake without providing the nutrients that a developing baby needs, making it harder to meet nutritional requirements from the core food groups while staying within a healthy calorie range.
Practical Ways to Stay Under 25 Grams
Sweetened drinks are the single largest source of added sugar in most diets. Replacing soda, sweetened coffee drinks, and fruit juice with water, sparkling water, or unsweetened tea eliminates the biggest contributor in one step. Beyond beverages, a few habits make a noticeable difference:
- Check sauces and condiments. Barbecue sauce, salad dressing, and pasta sauce often contain 4 to 8 grams of added sugar per serving.
- Swap flavored yogurt for plain. Adding your own fresh fruit gives sweetness with fiber and no added sugar.
- Compare cereals and granolas. The range is enormous. Some brands contain 2 grams per serving, others 16 grams.
- Watch “health” foods. Protein bars, smoothie bowls, and dried fruit with added coatings can carry as much sugar as a candy bar.
You don’t need to eliminate sugar entirely. The guidelines acknowledge that a small amount of added sugar fits within a healthy diet. The goal is staying aware of where it hides, so the grams don’t accumulate past the point where they start affecting your health.
