Most added sugar doesn't come from the sugar bowl. It comes in drinks, breakfast foods, and snacks that don't taste like dessert, and until the current label came in, it couldn't tell you how much had been added. This article covers the one line on the Nutrition Facts label that shows added sugar, how to read a label in about five seconds, why drinks are the one place that line can fool you, and what the research says about sugar and weight.

Key Points

What to Know About Hidden Sugar and Food Labels

  • Read one line: "Includes __g Added Sugars" sits under Total Sugars and counts only the sugar that was added.
  • Use the %DV next to it: 5% or less is low and 20% or more is high, based on a 50-gram daily limit.
  • Drinks are the exception: 100% juice shows 0g added, but a cup of apple juice has about as much sugar as a cup of cola.
  • Sugar-free doesn't mean low calorie: If a sugar-free food isn't lower in calories, the package has to say so.
  • The new guideline: No more than 10 grams of added sugar in any one meal.
Quick Answers

Quick Answers Before You Read Further

What does "Includes Added Sugars" mean on a food label?

It's the line indented under Total Sugars, and it shows how many grams of sugar were added to the food: table sugar, syrups, honey, and juice concentrate. It doesn't count the natural sugar in milk, fruit, or vegetables. The %DV next to it compares that amount to a daily limit of 50 grams.

How much added sugar is too much?

The Dietary Guidelines for Americans released in January 2026 say no amount of added sugar is recommended and that no single meal should have more than 10 grams. The food label's Daily Value is 50 grams a day, and the FDA's rule of thumb is that 20 percent of that or more in one serving is high.

Does 100% fruit juice have added sugar?

The label says no. Sugar that was already in the fruit isn't counted as added, so 100% juice shows 0 grams. A cup of 100% apple juice still has about 24 grams of sugar, close to the 26 grams in a cup of cola, and the new guidelines say to keep juice to small portions.

Does sugar-free mean low calorie?

It doesn't. Sugar-free, or "zero sugar," means less than half a gram of sugar per serving, and it says nothing about calories. When a sugar-free food isn't also low or reduced in calories, federal rules require the package to say so, with wording like "not a reduced calorie food" or "not for weight control."

Does cutting sugar help with weight loss?

It helps modestly, mostly through calories. In a review of randomized trials in adults, eating less sugar led to about 0.8 kilograms of weight loss and eating more led to a similar gain, while swapping sugar for other carbohydrates with the same calories changed nothing. Sugary drinks are the easiest calories to cut. Results vary person to person.

Where Added Sugar Comes From

When people try to cut sugar, they usually start with dessert and the sugar bowl. Those count, but they're not the biggest part of the total. In national survey data, sweetened drinks were the biggest single source of added sugar, about a quarter of it, and drinks overall, counting coffee and tea with sugar added, were about a third. Desserts and sweet snacks came next, then candy and sugar itself, then breakfast cereals and bars.

In 2017 and 2018, American adults averaged about 17 teaspoons of added sugar a day. A lot of it comes from foods that don't taste like dessert: flavored yogurt, granola bars, instant oatmeal, sauces, and bottled coffee drinks. One we hear a lot across the desk: "I thought granola was healthy." Some of it is, and the Added Sugars line is how you check.

At your first visit we go over what you eat and drink on a normal day. At follow-ups we go over your food log with you, including drinks, and look for where added sugar is coming in. We go over how to read the Added Sugars line using the foods you already buy. This article walks through the same thing.

The Line That Tells You What Was Added

Total Sugars counts every gram of sugar in a serving, including lactose, the natural sugar in milk, and the sugar in fruit. That's why plain Greek yogurt still shows about 5 grams of sugar even though none of it was added. For most of the label's history, that one number was all you got. The current label, required for larger food companies from January 2020 and for smaller ones from January 2021, added a line indented under it: "Includes __g Added Sugars." It counts sugar added during processing, sugar sold as a sweetener, syrups, honey, and juice concentrate beyond what 100% juice would have.

Nutrition Facts Per 6-oz cup · flavored is regular yogurt, not Greek Plain Greek Flavored
Total Sugars5g19g
Added Sugars0g13g
Protein16g6g

Typical label values; brands vary. The flavored cup here is regular yogurt, not Greek, which is why its protein is lower. The Added Sugars row is where the two split.

The %DV next to the Added Sugars line compares it to a Daily Value of 50 grams, based on a 2,000-calorie day. The FDA's rule of thumb is that 5 percent or less is low and 20 percent or more is high. A typical flavored yogurt cup lands around 22 to 26 percent. Plain Greek yogurt lands at 0, with around 16 grams of protein in a 6-ounce cup.

Reading a Label in About Five Seconds

You don't need to read the whole panel. Three stops cover it: the serving size, the Added Sugars line, and the percentage next to it.

  1. Serving size

    Check it against what you'll actually eat. A package you'd finish in one sitting, like a 20-ounce soda, is now labeled as one serving. Bigger packages still list more than one serving.

  2. Added Sugars

    Find "Includes __g Added Sugars" right under Total Sugars. Divide the grams by 4 to get teaspoons.

  3. The %DV

    Look at the percentage next to it. 5 percent or less is low, and 20 percent or more is high.

5% OR LESS: LOW 20% OR MORE: HIGH

On anything you drink, add a fourth stop and read Total Sugars too. The next section explains why.

Why Drinks Are the Exception

A cup of 100% apple juice has about 24 grams of sugar, close to the 26 grams in a cup of cola, and its label says "Includes 0g Added Sugars." By the rules that's correct. Sugar that was already in the fruit isn't counted as added, and neither is juice concentrate used to make 100% juice. Your body still gets all 24 grams, though. The World Health Organization counts the sugar in fruit juice as "free sugars," in the same group as table sugar and honey, and the new U.S. guidelines say 100% juice should be kept to small portions or watered down.

1 cup of cola 26 g about 6½ teaspoons
1 cup of 100% apple juice 24 g about 6 teaspoons, label says 0g added
Water or unsweetened tea 0 g none

Typical label values. Four grams of sugar is about a teaspoon.

Drinks matter for a second reason. In one study, 15 adults took in an extra 450 calories a day for four weeks, once as soda and once as jelly beans. With the jelly beans, they ate less at meals and it evened out. With the soda, they didn't, and their weight went up. That fits a review of randomized trials showing that sugar's effect on weight runs mostly through calories.

Two we hear a lot: "It's 100% juice, so it's healthy" and "I don't drink soda, just sweet tea." Sweet tea is sweetened with sugar that was added, so its label counts every gram of it. For coffee, flavored creamer has its own Added Sugars line; check the serving size against how much you pour.

The Breakfast Foods That Look Healthy

Breakfast is where a lot of hidden sugar sits, because the foods look like the healthy choice. From typical labels, a pouch of two crunchy granola bars lists about 11 grams of added sugar, a packet of maple instant oatmeal about 12, and a 6-ounce cup of regular flavored yogurt 11 to 13. Each one is over the 10 grams the new guidelines set for a whole meal, and none of them tastes like dessert.

The fix is usually the plain version. Plain Greek yogurt and plain oats both list 0 grams added. Top them with fruit or cinnamon. If you add honey, it counts as added sugar, but at least you can see how much went in. We use a lot of plain Greek yogurt in the clinic for that reason. It also helps with protein: around 16 grams in a 6-ounce cup, toward the 30 grams at breakfast we set in the protein plan.

One more we hear a lot: "Fruit has too much sugar." Whole fruit's sugar isn't added sugar, and the new guidelines draw the same line. They recommend avoiding added sugar while allowing the natural sugar in whole fruit and plain dairy. Results vary person to person.

Sugar-Free, No Added Sugar, and What They Mean

The front of the package and the label on the back answer different questions. "Sugar-free" and "zero sugar" mean the same thing: less than half a gram of sugar per serving. It says nothing about calories, and when a sugar-free food isn't also low or reduced in calories, the rules require the package to say so, with wording like "not a reduced calorie food," "not a low calorie food," or "not for weight control." "No added sugar" means nothing containing sugar was added during processing, but the food can still have plenty of its own sugar, like juice or dried fruit, and it carries the same kind of calorie statement.

We hear "It's sugar-free, so I can have more" a lot. The answer is the same as everywhere else in this article: check the calories and the serving size on the back. The new federal guidelines also say no amount of low- or no-calorie sweetener is recommended as part of a healthy diet. When diet soda comes up, we tell patients it's better than regular soda, and water is still the goal.

Where to Start

Pick three things you buy every week and read the Added Sugars line on each. Swap one sweet drink a day for water, unsweetened tea, or plain coffee. Keep one meal a day at 10 grams of added sugar or less; plain Greek yogurt with fruit gets you there and adds protein. If you'd like help figuring out where the sugar in your day is coming from, a clinician-supervised weight-loss program at Optimized Health starts with a comprehensive clinical evaluation, and at your first visit we go over what you eat and drink on a normal day. We see patients in Joplin and by telehealth in MO, KS, IA, UT, and WA. Results vary person to person.

Where this comes from: the Added Sugars line, the 50-gram Daily Value, the 5 and 20 percent rule of thumb, the serving-size rule, and the compliance dates are from the FDA's Nutrition Facts label rules (21 CFR 101.9) and its consumer guidance; the sugar-free and no-added-sugar definitions are from 21 CFR 101.60; the 10-gram meal limit, the juice guidance, and the sweetener statement are from the Dietary Guidelines for Americans, 2025–2030; the sources of added sugar are from the Dietary Guidelines for Americans, 2020–2025, using NHANES 2013–2016, and the 17-teaspoon average from the CDC's added sugars data for 2017–2018; the definition of free sugars is from the World Health Organization's 2015 sugars guideline; the weight findings are from Te Morenga and colleagues' 2013 review in the BMJ; the soda and jelly bean study is DiMeglio and Mattes, International Journal of Obesity, 2000; the sports drink finding is the American College of Sports Medicine's 1996 position stand on exercise and fluid replacement; the sugar addiction review is Westwater and colleagues, European Journal of Nutrition, 2016; food and drink figures are typical product labels and USDA values.

More Questions

Common Questions About Hidden Sugar

We hear "fruit has too much sugar" a lot. Whole fruit's sugar isn't counted as added sugar on a label, and the new federal guidelines recommend avoiding added sugar while allowing the natural sugar in whole fruit and plain dairy. Juice is different: the same guidelines say to keep 100% juice to small portions or water it down. Whole fruit is one of the easier swaps when you want something sweet.
"It's natural sugar, so it doesn't count" is one we hear a lot. On the label, honey, syrups, and agave all count as added sugar, and the World Health Organization groups the sugar in honey and syrups with table sugar. Gram for gram, count them the same as table sugar.
When diet soda comes up, we tell patients it's better than regular soda, and water is still the goal. A 12-ounce can of regular cola has about 39 grams of sugar, so the swap takes out real sugar. The new federal guidelines don't count low- or no-calorie sweeteners as part of a healthy diet, which is why water or unsweetened tea is where we want you to end up.
"I need a sports drink for the electrolytes" comes up a lot. For exercise lasting less than an hour, the American College of Sports Medicine found little difference between a sports drink and plain water; the carbohydrate and electrolytes help in events longer than an hour. Sports drinks carry added sugar, so for daily life and most workouts, water covers it.
It covers sugar added during processing, sugar sold as a sweetener, syrups, honey, and juice concentrate beyond what 100% juice would have. The natural sugar in milk, fruit, and vegetables doesn't count, and neither does the sugar in 100% fruit or vegetable juice. That's why plain Greek yogurt shows about 5 grams of Total Sugars and 0 grams added.
We hear this one a lot. Cravings are real, but a 2016 review of the research found little evidence that sugar is addictive in people the way drugs are; the bingeing seen in rat studies showed up only when sugar was available on and off. You don't have to quit everything at once. Pick one swap from this article and start there. Consistency over intensity.
"It's just a splash of creamer" is one we hear a lot. Flavored creamer has its own Nutrition Facts label with an Added Sugars line, and the numbers are per serving, so check the serving size against how much you pour. Plain milk or regular half-and-half has no added sugar. Flavored syrups at a coffee shop are added sugar.
It can be. Plain Greek yogurt lists 0 grams of added sugar, but flavored versions, Greek or not, often have added sugar, so check the Added Sugars line. The simplest fix is plain Greek yogurt with fresh fruit mixed in, which keeps the added sugar at zero and the protein high.
