Added sugar
Added sugars are sugars and syrups added during processing or preparation — distinct from the sugars naturally present in fruit, vegetables, and milk. The WHO 2015 guideline recommends free sugars below 10% of energy (strong) and below 5% (conditional). The DGAs 2020–2025 recommend below 10%; the AHA suggests below 25 g/day for women and 36 g/day for men.
What counts as added sugar?
Added sugars are sugars and syrups added to a food during processing or preparation, distinct from sugars naturally present in intact fruit, vegetables, and dairy. The FDA definition covers sucrose, high-fructose corn syrup, dextrose, invert sugar, agave, honey, maple syrup, coconut sugar, malt syrup, brown-rice syrup, and any concentrated fruit juice used as a sweetener rather than a food.

How added sugar reaches the food supply
| Category | Share of US added-sugar intake |
|---|---|
| Sugar-sweetened beverages | ~24% |
| Desserts and sweet snacks | ~19% |
| Sweetened coffee and tea | ~11% |
| Breakfast cereals and bars | ~7% |
| Candy and sugars | ~9% |
| Sauces, condiments, dressings | ~5% |

Outcome evidence
Malik and Hu (Nature Reviews Endocrinology 2022;18:205–218) reviewed 30+ prospective cohorts and RCTs on sugar-sweetened beverages: an additional serving per day raised type-2 diabetes incidence by 18–26% and cardiovascular events by 17–21%. The signal is largest for beverages because liquid sugar bypasses the satiety response that would follow the same dose eaten in a solid whole food. Te Morenga, Mallard, and Mann (BMJ 2013;346:e7492) found that isocaloric exchanges of sugar for other carbohydrate did not change body weight, but adding sugar on top of habitual intake did — consistent with an energy-balance mechanism rather than a metabolic magic.
Why "added sugar" tracks with Group 4
Added sugars are the archetypal cheap functional ingredient. Where they appear, so usually do emulsifiers, flavour systems, and colours — the additive profile that defines a Group 4 formulation (Monteiro 2019). The added-sugar line on the label is one of the fastest visual cues for the NOVA group; see how to spot ultra-processed food for the pattern in ingredient lists.
How NakedCalorie treats added sugar
Added-sugar grams are shown on the nutrient panel and count as an ingredient marker toward Group 4 classification via HFCS, sucrose, and syrup forms. Non-sugar sweeteners such as stevia replace the sugar line but not the NOVA classification. See the Nutrition Facts panel for the label mechanics.
Frequently asked questions
- Is fruit sugar the same as added sugar?
- No. Whole fruit contains fructose and glucose bound inside an intact cell-wall matrix with fibre, water, and polyphenols. The Nutrition Facts panel counts these as 'total sugars' but not 'added sugars'. Cohort data (Aune 2017) associate whole fruit intake with lower mortality; added sugars in beverages associate with the opposite.
- Why did the WHO set two thresholds?
- The 10% threshold reflects the observed effect on dental caries and weight (strong recommendation). The 5% threshold reflects further caries reduction seen in older cohort studies (conditional — evidence limited). Both refer to 'free sugars': all added sugars plus those naturally present in honey, syrups, and fruit juice.
- What does the 'Added Sugars' line on the Nutrition Facts panel mean?
- Since the FDA's 2016 rule (enforced 2020), US labels declare added sugars in grams and as a percent of a 50 g daily value. The line covers sucrose, HFCS, honey, maple syrup, agave, invert sugar, and any concentrated fruit juice used as a sweetener.
- Is HFCS worse than sucrose?
- Fructose:glucose ratios overlap substantially — HFCS-55 is 55% fructose / 42% glucose, sucrose is 50/50 after hydrolysis. Controlled feeding trials (Sievenpiper, Annals of Internal Medicine 2012;156:291–304) show similar metabolic effects at matched dose. What is well supported: total added-sugar dose from either source, delivered in beverages, is a cardiometabolic hazard.
- Do non-sugar sweeteners help?
- The WHO 2023 guideline on non-sugar sweeteners recommends against their use for weight control, citing possible long-term risks in prospective cohorts. Short-term RCTs still show weight loss when NSS replace sugar-sweetened beverages (McGlynn, JAMA Network Open 2022;5:e2222092) — the trade-off remains contested.
