What are added sugars?
Added sugars are sugars added to foods during processing, preparation, or at the table. This may include sugars from sugar, glucose, dextrose, syrups, honey, and concentrated fruit or vegetable juices.
This does not refer to all sweet carbohydrates. Sugars that occur naturally in the raw ingredients, such as lactose in milk or fructose in whole fruit, are included in total sugars but are generally not classified as added sugars.
How is it different from total sugars?
Total sugars are the combined value of sugars naturally present in the food and sugars added during processing. Added sugars are the portion added later. Therefore, added sugars cannot be greater than total sugars.
If a yogurt is labeled with 10g of total sugars and 4g of added sugars, the 4g is included within the total 10g. Calculating them as 14g by adding the two values would be double-counting.
Is it the same as free sugars?
Free sugars, as defined by the World Health Organization, include not only sugars added by manufacturers, cooks, or consumers but also sugars found in honey, syrups, fruit juices, and concentrated fruit juices. While there is significant overlap with added sugars, the scope varies depending on the defining organization and purpose.
This is why sugars within the cellular structure of whole fruit when chewed are not classified in the same context as sugars consumed as fruit juice. First, check which definition the document is using.
How do I find it in the ingredients list?
You might miss some if you only look for the word 'sugar'. It can be listed under various names such as sucrose, glucose, high-fructose corn syrup, starch syrup, syrup, honey, or concentrates. Ingredients are generally listed in descending order of weight, but detailed rules vary by country and food type.
Even if several sugar ingredients are listed separately, if there is an 'added sugars' item in the nutrition facts, check it along with the grams per serving. Do not estimate the amount based solely on the number of names listed.
How do I read it on the nutrition facts label?
First, serving sizeCheck the number of servings per package. If 5g of added sugar is the standard for 1 serving and you consumed 2 servings, the actual intake is 10g.
The method for labeling added sugars may vary by country. Do not assume there are no added sugars just because there is no separate category; check both the total sugars and the ingredients list.
How is it related to weight management?
Added sugars in sweet beverages, desserts, and snacks can easily increase energy intake compared to the feeling of fullness they provide. In particular, liquid calories lack the chewing process, making it easy to consume large amounts in a short time.
However, weight change is not determined by added sugar alone. We look at total energy intake, eating patterns, and the long-term flow of sleep and activity together.
Is this the same concept as the Glycemic Index?
Added sugar describes whether sugar has been added to a food, Glycemic Indexwhile the Glycemic Index describes the relative blood sugar response after eating a certain amount of available carbohydrates. The questions themselves are different.
Starchy foods without added sugar can still cause a rapid blood glucose response, and sweet foods high in fat may have a lower glycemic index than expected energy densityeven if the glycemic index is lower than expected.
What should I change first when reducing sugar?
First, identify daily habits such as sugary drinks, sweetened coffee, and large packages of snacks. Rather than an absolute ban, it is easier to track the impact of change by gradually reducing the frequency, portion size, or sweetness level.
Replace some snacks with options that can be eaten with protein, such as fruit, plain yogurt, or nuts.dietary fiberFavorite desserts can be incorporated into your overall diet by setting a specific time and amount for consumption.
What are some common misconceptions?
Brown sugar, raw sugar, honey, and syrups also provide sugars that the body utilizes. The fact that they are colored differently or described as naturally derived does not mean you can ignore the amount consumed.
Conversely, if you restrict natural sugars in fruit and milk for the same reasons, your intake of dietary fiber, protein, and micronutrients may decrease. Distinguish between the structure of the food and its overall nutrition.
Guidelines for safe application
diabetes People using medication or insulin should not arbitrarily adjust carbohydrate intake or medication dosages based solely on added sugar. Review total carbohydrates, meal timing, and the risk of hypoglycemia with your medical team.
Fear-based sugar restriction may not be appropriate for those in growth periods or those at risk of eating disorders. If you experience persistent thirst, polyuria, or unexplained weight changes, standard medical tests take priority over food labels.
The actual process for comparing two foods
If comparing sweetened yogurt and cereal, first adjust the serving size to the grams you will actually eat, then note the total sugars, added sugars, protein, and dietary fiber. Even if the added sugar is lower, the total intake may differ if the actual amount eaten at once is double.
Finally, consider whether the food is eaten as a standalone snack or as part of a meal with fruit or milk. Rather than the food with the lowest numbers, a combination that can be eaten repeatedly and manages hunger until the next meal is more practical.
Do 'unsweetened' or 'sugar-free' labels mean 0g of added sugar?
Do not judge total sugars and added sugars based solely on highlighted phrases on the front of the packaging. 'Unsweetened' may be used in the context that no sugar was added during manufacturing, but sugars naturally present in the raw ingredients may remain, and labeling standards vary by country and food type. 'Sugar-free' foods may still contain starch, other carbohydrates, or sweeteners.
Check the actual serving size, total carbohydrates, total sugars, and added sugars on the nutrition facts label, and review the ingredients list. Do not assume that foreign food labels follow the same standards as domestic labeling. If blood glucose management is necessary, judge based on the total carbohydrates of the amount you eat and the overall meal composition rather than a single phrase on the front.
Does the quality of the diet automatically improve if I only reduce added sugar?
The fact that added sugar is low does not explain the food's protein, dietary fiber, sodium, or overall energy density. A snack or drink with 0g of added sugar does not automatically become a balanced meal. Conversely, yogurt with a small amount of added sugar can be a realistic choice when eaten with protein and fruit; therefore, foods should not be categorized as 'good' or 'bad' based on a single number.
First, adjust items with high intake and low nutritional replacement effect, such as sweetened beverages and frequent large desserts. If the space left by these is not filled with water, whole fruits, and actual meals, other snacks may increase. You can determine if the change is sustainable by looking at the average intake over 1 to 2 weeks, along with hunger and meal satisfaction.

The nutrition facts label is a table showing calories and nutrients per a set reference amount. Since the numbers correspond to a reference such as 1 serving size or 100g rather than the actual amount eaten, you must first align the servings per package with your own intake amount to use it for comparison.
→ Diet & Nutrition serving sizeA serving size is a reference amount established to calculate and display nutritional information. It may not be the same as the actual portion size you consume at one time, and the listed calories and nutrients must be converted based on the number of servings consumed.
→ Diet & Nutrition Glycemic LoadThe Glycemic Load (GL) is a value that reflects the amount of available carbohydrates in an actual 1-time intake amount based on the food's glycemic index. While it considers both the quality and quantity of carbohydrates, it is not a diagnostic indicator that accurately predicts mixed meals and individual blood glucose responses.
→ Diet & Nutrition Energy DensityEnergy density is the amount of energy contained per 1g or 100g of food weight. Foods high in water and dietary fiber tend to have lower energy density, while foods with low moisture or a high proportion of fat tend to have higher energy density; however, it is not an indicator used to determine nutritional value or healthiness with a single number.
→ Diet & Nutrition Dietary fiberDietary fiber is a carbohydrate component that is not completely broken down by human digestive enzymes and passes through to the small intestine. Depending on the type, the degree of water solubility, fermentability, and viscosity vary, meaning the effects on bowel movements, satiety, and postprandial blood glucose are not the same.

Frequently Asked Questions About Added Sugars
Is the sugar content in fruit considered added sugar?
Sugars naturally present in fresh fruit are generally not added sugars. However, when fruit juice is concentrated or processed into juice, the classification of free sugars and the context of consumption may change.
Are honey and maple syrup not added sugars because they are natural?
Even if the source of the ingredient is natural, if it is added to food or beverages to provide sweetness, it may be included in the added sugar category.
Does 'sugar-free' mean there are no sugars at all?
Depending on the labeling standards, it may simply mean that no sugar was added, but sugars naturally present in the raw ingredients or other sweeteners may still be present. Please check the actual nutrition facts and ingredients list.
Will I lose weight if I only reduce added sugars?
Reducing added sugars in sweet drinks and snacks can help with overall energy management, but you must also consider total food intake, other nutrients, and physical activity.
