One 12-ounce can of regular cola contains about 39 grams of added sugar.
The American Heart Association’s daily limit for women is 25 grams. For men, 36 grams.
That single can exceeds an entire day’s recommended intake for women, and nearly hits the ceiling for men — before any food is eaten.
The average American consumes roughly 23 teaspoons of added sugar daily, about 74 pounds a year. The recommended maximum is 6 to 9.
Quick Fact: The 2025-2030 Dietary Guidelines for Americans shifted to a per-meal framework — recommending no single meal contain more than 10 grams of added sugars, which pushes the effective daily total below the older 50-gram ceiling.

The Numbers, and Why They Differ
Three major bodies publish limits, and they don’t fully agree:
American Heart Association: No more than 25g (6 tsp) daily for women, 36g (9 tsp) for men — roughly 6% of daily calories.
World Health Organization: Below 10% of total energy from free sugars, with a conditional recommendation to aim under 5% — approximately 25g on a 2,000-calorie diet.
Dietary Guidelines for Americans (2025-2030): Under 10% of calories, plus the newer per-meal guidance of no more than 10g of added sugars in any single meal.
The AHA numbers are the strictest and the most commonly cited. If you want one figure to work with, 25g for women and 36g for men is the practical benchmark.
Quick Reference: Daily Added Sugar Limits
| Source | Women | Men | Notes |
|---|---|---|---|
| American Heart Association | 25g (6 tsp) | 36g (9 tsp) | ~6% of calories |
| WHO | ~25g | ~25g | <5% of calories (conditional) |
| Dietary Guidelines 2025-2030 | <10% of calories | <10% of calories | Plus ≤10g per meal |
| Average U.S. intake | ~96g | ~96g | ~23 tsp/day |
Added vs. Natural Sugar — The Distinction That Matters
Your body processes the sugar molecule identically whether it comes from an apple or a soda. That’s true, and it’s often used to argue the distinction is meaningless.
It isn’t, and the reason is absorption speed.
An apple contains fiber, which slows digestion and moderates how quickly sugar enters the bloodstream. A soda has no fiber — the sugar hits all at once. Same molecule, entirely different metabolic experience.
There’s also a volume issue. The sugar in one 12-ounce soda is roughly equivalent to one orange plus 16 strawberries plus two plums. Nobody accidentally eats that much fruit. Liquid sugar bypasses the natural portion limits that whole food imposes.
This is why guidelines target added sugars specifically rather than total sugars — and why the Nutrition Facts label now separates the two.
What Excess Sugar Actually Does
Liver overload. High sugar intake — particularly fructose — drives the liver to convert carbohydrate into fat, contributing to non-alcoholic fatty liver disease.
Cardiovascular risk. A 2023 study in BMC Medicine following more than 110,000 people over about nine years found higher added sugar intake associated with higher risks of heart disease and stroke, in a dose-dependent pattern.
Insulin resistance. Repeated sharp blood sugar spikes place ongoing demand on insulin response, contributing over time to type 2 diabetes risk.
Weight gain. Added sugars supply calories with essentially no nutrients — roughly 460 empty calories daily at average U.S. intake.
Dental cavities. Oral bacteria metabolize sugar and produce acid that erodes enamel.
Where It Actually Hides
The obvious sources — soda, candy, desserts — are only part of the picture. The harder problem is sugar in foods that don’t taste especially sweet:
- Pasta sauce: 6-10g per half cup
- Ketchup: ~4g per tablespoon
- Granola bars: 8-12g
- Flavored yogurt: frequently 15-20g+
- Bread: 2-5g per slice in many commercial varieties
- Salad dressing: 3-7g per serving
- Flavored coffee drinks: 25-50g
A telling benchmark: the FDA’s threshold for a “healthy” claim on dairy snacks caps added sugar at 2.5 grams per serving. Most flavored yogurts on the shelf exceed that by a wide margin.
Quick Reference: Common Items vs. Daily Limit
| Item | Added Sugar | % of Women’s Daily Limit (25g) |
|---|---|---|
| 12 oz cola | ~39g | 156% |
| Flavored coffee drink | 25–50g | 100–200% |
| Flavored yogurt (single) | ~20g | 80% |
| Granola bar | 8–12g | 32–48% |
| Pasta sauce (½ cup) | 6–10g | 24–40% |
| Ketchup (1 tbsp) | ~4g | 16% |
The Honest Nuance
Coverage of sugar often runs to extremes, so it’s worth noting where the evidence is less settled than headlines suggest.
A narrative review examining the WHO’s under-10% recommendation concluded it is not strongly supported by the available evidence, pointing to real limitations in the research base.
More specifically: most studies linking high free sugar intake to poor health outcomes focused on sugar-sweetened beverages. Studies examining free sugars from solid food sources have more often reported null findings.
This doesn’t undo the case for limiting added sugar. It does suggest the evidence is strongest for liquid sugar — soda, juice, sweetened coffee — and less definitive for sugar in solid foods.
The practical implication is useful: if you’re going to prioritize one change, cut sugary drinks first. That’s where the evidence is clearest and the quantities are largest.
What People Actually Discover
The most common realization when people start reading the added sugars line is that their intake was already high before dessert entered the picture.
Breakfast is a frequent surprise. Flavored yogurt, granola, a sweetened coffee, and commercial bread can total 40-50g before 9 a.m. — past the daily limit, with none of it registering as “eating sugar.”
The second pattern is taste recalibration. People who reduce added sugar consistently report that after several weeks, previously normal foods taste cloyingly sweet. This is the same adaptation that occurs with sodium, and it means the first two or three weeks are the hardest part rather than a permanent state.
Third: the “healthy” label problem catches almost everyone. Granola, protein bars, smoothies, and flavored yogurts are marketed on their nutritional merits while frequently carrying more added sugar than a cookie. Checking the label rather than the front of the package is the habit that resolves this.
Common Mistakes
Counting total sugars instead of added sugars. Total includes natural sugar from fruit and milk. The Added Sugars line is the one that maps to the guidelines.
Assuming honey, agave, or coconut sugar are exempt. All count as added sugars. The AHA is direct: added sugar is added sugar regardless of the name.
Overlooking beverages. Liquid sugar is where the evidence is strongest and the quantities largest — and it’s the easiest category to consume without noticing.
Trusting front-of-package health claims. Marketing language follows looser rules than the Nutrition Facts panel. Turn the package over.
Focusing only on obvious sweets. Sauces, dressings, bread, and yogurt contribute substantially without tasting like dessert.
Expecting cravings to persist forever. Taste preference recalibrates over several weeks. Judging the change after three days judges it at the worst moment.
Practical Tips
- Cut sugary drinks first — this single change addresses the category with the clearest evidence and the largest amounts.
- Read the Added Sugars line specifically, not Total Sugars.
- Check three staples you buy weekly — pasta sauce, bread, and yogurt are the most common surprises.
- Buy plain yogurt and add fruit yourself rather than buying flavored; this alone often saves 15g+ per serving.
- Give it three to four weeks before evaluating; palate adaptation takes about that long.
- Use the 10g-per-meal guideline as a working target rather than tracking a daily total.
If you’re evaluating other nutrition claims, it’s worth pairing this with our guides on how to read a nutrition label and ultra-processed foods, since added sugar is one of the specific things label-reading is most useful for.
When Should You See a Doctor?
Talk to a doctor or registered dietitian about sugar intake if you have diabetes or prediabetes, since carbohydrate targets are individualized and differ meaningfully from general population guidance. This is also worth discussing if you have non-alcoholic fatty liver disease, elevated triglycerides, or metabolic syndrome — all of which are directly influenced by added sugar intake.
Seek guidance as well if attempts to reduce sugar feel compulsive or trigger distress around eating, rather than working through that alone.
Frequently Asked Questions
How many grams of added sugar per day is too much? The American Heart Association recommends no more than 25g (6 teaspoons) for women and 36g (9 teaspoons) for men. Average U.S. intake is around 96g daily.
Does sugar in fruit count toward the limit? No. Guidelines target added sugars specifically. Whole fruit contains fiber that slows absorption, and it isn’t included in added sugar recommendations.
Is honey healthier than white sugar? Not meaningfully in this context. Honey, agave, maple syrup, and coconut sugar all count as added sugars under the guidelines.
Which is worse — sugar in drinks or in food? The evidence is strongest for beverages. Most research linking added sugar to poor health outcomes focused on sugar-sweetened drinks, while studies of solid-food sugars have more often shown null results.
How long until sugar cravings decrease? Most people report noticeable taste recalibration within three to four weeks of consistently reducing intake, with the first couple of weeks being the hardest.
The Bottom Line
The daily limit — 25 grams for women, 36 for men — is easy to exceed before you’ve eaten anything you’d think of as sugary. Read the Added Sugars line rather than Total Sugars, check the three staples most likely to surprise you, and if you only change one thing, make it drinks. That’s where the evidence is clearest, the amounts are largest, and the win is easiest.
