How much sugar per day is too much?
Sugar is a source of energy for your body. But how much is "enough" is something many people aren't sure about.
The World Health Organization (WHO) and the Dietary Guidelines for Americans recommend keeping added sugar under 10% of your daily calories. The American Heart Association (AHA) sets a stricter limit.
Guideline | Daily added sugar limit | About |
|---|---|---|
WHO / Dietary Guidelines (2,000 calorie diet) | 50 g | 12 teaspoons |
AHA, women | 25 g | 6 teaspoons |
AHA, men | 36 g | 9 teaspoons |
For extra health benefits, the WHO suggests going even lower, under 5% of calories, or about 25 g (6 teaspoons) a day.
To put that in perspective: a 12 oz can of regular cola contains about 39 g of sugar. One can can take you close to the daily limit, before counting sugar from anything else.
Managing sugar matters just as much as creating a calorie deficit, because added sugar is often "empty calories": energy without much nutrition.
Natural sugar vs. added sugar
This is the most important distinction.
Natural sugar is already in whole foods: fructose in fruit, lactose in milk. These foods come with fiber, vitamins, and minerals, so there's no specific limit and they're not a concern in normal amounts.
Added sugar is put into food during processing or cooking: table sugar, corn syrup, honey, and syrups. This is the kind linked to weight gain and health problems. When experts talk about sugar limits, they mean added sugar, not the sugar in fruit or milk.
For example, eating an orange with about 12 g of natural sugar is very different from drinking a sweetened orange juice. The fiber in whole fruit slows sugar absorption, while juice sends sugar into your bloodstream quickly.
When you eat out, hidden sugar in sauces, dressings, and drinks is the easiest to miss.
Why too much sugar is a problem
Weight gain. Added sugar is high in calories and low in nutrients. Extra sugar beyond what your body needs gets stored as fat.
Higher risk of chronic disease. Diets high in added sugar are linked to a higher risk of type 2 diabetes, high blood pressure, and heart disease.
Energy and mood swings. Sugar can cause blood sugar spikes and crashes, leading to fatigue, irritability, and trouble focusing.
Skin health. High sugar intake is linked to changes in collagen that may affect skin over time.
If you're working toward a goal like losing weight at a safe pace, cutting added sugar is one of the easiest ways to create a deficit without cutting other foods.
Signs you may be eating too much sugar
Frequent hunger and sugar cravings: sugar doesn't keep you full and can disrupt hunger signals.
Fatigue and irritability: blood sugar ups and downs affect your mood.
Skin breakouts: high sugar intake is linked to inflammation.
Brain fog: trouble concentrating after sugary meals.
Easy ways to cut back on sugar
1. Use less sugar when cooking and baking. Many recipes still taste great with less sugar. Try using mashed fruit, dates, or sweet potato for natural sweetness.
2. Read nutrition labels. Sugar hides in foods that don't taste sweet: ketchup, BBQ sauce, teriyaki sauce, flavored yogurt, granola, and bottled dressings. Check the "Added Sugars" line on the label.
3. Choose drinks carefully. Drinks are the biggest source of added sugar and the easiest to overlook. Instead of soda or sweet coffee drinks, try:
Water (best)
Unsweetened tea or black coffee
Sparkling water with lemon or mint
Gradually less sugar in your tea or coffee
A full-sugar bubble tea can have 300 to 500 calories, as much as a meal.
4. Choose fruit over candy. When you want something sweet, try apples, berries, kiwi, or pears, and pair them with plain Greek yogurt.
5. Eat slowly and share. Enjoy dessert slowly, and share it instead of eating a large portion alone.
Good news: your sweet tooth can change. When you cut back over time, cravings fade, and foods you used to love may start to taste too sweet.
FAQ
How much sugar per day is safe? The WHO recommends keeping added sugar under 50 g per day (10% of calories) and ideally under 25 g (about 6 teaspoons). The AHA recommends no more than 25 g for women and 36 g for men.
Does sugar from fruit count toward the limit? No. The limits apply to added sugar, not the natural sugar in whole fruit or milk.
How much sugar is in a can of soda? A 12 oz can of regular cola has about 39 g of sugar, close to or above the daily limit.
How many grams of sugar are in a teaspoon? A level teaspoon of granulated sugar is about 4 g. A tablespoon is about 12 g.
How can I eat less sugar? Use less when cooking, read labels for added sugars, choose water or unsweetened drinks, and reach for fruit instead of candy.
Is sugar addictive? Sugar activates the brain's reward system, which can drive cravings. That's why cutting back can feel hard at first, but taste preferences adjust over time.
The bottom line
How much sugar should you eat per day?
No more than 50 g of added sugar (10% of calories), according to the WHO
Ideally under 25 g (about 6 teaspoons) for better health
The limit applies to added sugar, not the natural sugar in fruit. Controlling sugar doesn't mean giving up sweets entirely. It means knowing how much you're eating and making smarter choices: water instead of soda, reading labels, and using less sugar when cooking.
