No Added Sugar Protein Bars: How to Tell If a Bar Really Qualifies

Not all no added sugar protein bars get there the same way, even though the label claim sounds identical from bar to bar. A protein bar qualifies as "no added sugar" when the Nutrition Facts panel shows 0g on the "Added Sugars" line — the specific line the FDA requires, separate from Total Sugars. That line can read 0g whether a bar is sweetened with a whole food like dates or with a sugar alcohol or rare sugar that's exempt from the added-sugars count. Both are technically "no added sugar." They're not the same bar. Here's how to check any label yourself in under 30 seconds, and what That's All Protein's own label looks like when you do.

What Does "No Added Sugar" Actually Mean on a Label?

Direct Answer: "No added sugar" means no sugar was added to the product during processing or packaging. On the Nutrition Facts panel, this shows up as 0g on the "Added Sugars" line specifically — a line the FDA has required since 2020, separate from "Total Sugars," which includes naturally occurring sugar from ingredients like fruit or dairy.

Per the FDA, added sugars include sugars added during processing (like sucrose or dextrose), sugar sold as a standalone sweetener, and sugars from syrups, honey, or concentrated fruit juice — but they do not include sugar that occurs naturally in whole foods like fruit, vegetables, or milk (High Confidence: FDA, Added Sugars on the Nutrition Facts Label). That's the whole distinction in one sentence: added sugars are sugars a manufacturer put in. Total sugars include everything, including sugar a whole-food ingredient brought with it naturally.

A protein bar sweetened only with organic dates can correctly show 0g Added Sugars even though its Total Sugars number is higher — because the sugar in dates isn't "added," it's part of the fruit. That's not a loophole. It's the same rule that applies to a bowl of grapes or a glass of milk.

How to Check Any Protein Bar's Label in 30 Seconds

Direct Answer: Flip the bar over, find the Nutrition Facts panel, and look for two numbers: "Total Sugars" and, indented underneath it, "Includes [X]g Added Sugars." If the Added Sugars line reads 0g, the bar legally qualifies for a "no added sugar" claim — regardless of what the Total Sugars line says.

Most people scan the ingredient list for sweeteners instead of checking this specific line, which is understandable — the Nutrition Facts panel is dense, and the Added Sugars line is easy to miss under Total Sugars. But the ingredient list alone won't confirm the claim; the Added Sugars line is the one number the FDA actually regulates for this specific label statement.

The Loophole to Watch For

Direct Answer: Sugar alcohols (like erythritol and maltitol) and allulose can also produce a 0g Added Sugars line, because the FDA doesn't count them the same way it counts sucrose — but they're not whole foods, and some cause digestive discomfort in sensitive people. Allulose, for example, is excluded from both Total Sugars and Added Sugars under current FDA guidance (High Confidence: FDA, Declaration of Allulose on Nutrition and Supplement Facts Labels).

This is the gap between the label claim and what a shopper usually wants. A bar sweetened with maltitol can legitimately say "no added sugar," but maltitol is a sugar alcohol with its own well-documented digestive tradeoffs at higher doses. For the full mechanism — glycemic index, gut fermentation, and which sugar alcohols show up in which mainstream bars — see That's All Protein's guide to protein bars without sugar alcohols.

Why Dates Are Different

Direct Answer: Dates are a whole fruit, so their natural sugar content isn't classified as "added sugar" under FDA rules — and unlike a sugar alcohol or an isolated sweetener extract, dates also bring fiber, potassium, and magnesium along with the sweetness.

That's the short version. For the fuller picture — glycemic index research, how dates function as both a sweetener and a binder, and how they compare to every other common protein bar sweetener — see That's All Protein's guide to date-sweetened protein bars. For more on dates themselves as an ingredient, see That's All Protein's guide to organic dates as a natural sweetener.

That's All Protein's Label as a Worked Example

Direct Answer: The That's All Protein Peanut Protein Bar has four ingredients — Grass-Fed Non-GMO Whey Protein, Organic Peanuts, Organic Dates, and Organic Cacao Butter — and shows 0g on the Added Sugars line and 0g on the Sugar Alcohol line, because organic dates are the only source of sweetness in the bar.

Run the 3-Line Label Check above on any That's All Protein bar and it passes cleanly: 0g added sugars, no sugar alcohol line at all, and the sweetener sitting plainly in the ingredient list as "Organic Dates" — not an extract, not an alcohol, not a name you'd need to search to understand. Every That's All Protein bar (Chocolate, Coffee, and Peanut) is built the same way: 4–7 organic ingredients, 15g of protein, and dates as the sole sweetener. No syrups, no sugar alcohols, no artificial sweeteners, no honey.

For shoppers managing blood sugar specifically: That's All Protein bars use less than one date per bar, within the moderate range generally discussed in glycemic-index research on dates (Medium Confidence — individual response varies; consult your doctor before making decisions based on this general information).

Shopping Checklist: Is a "No Added Sugar" Bar Actually What You Want?

This checklist covers added sugar specifically. For a broader rundown of every ingredient category worth checking on a protein bar label, see That's All Protein's protein bar ingredients guide.

• Check the Added Sugars line first. If it's not 0g, the "no added sugar" claim on the front of the package is doing more marketing than the label supports.
• Check the Sugar Alcohol line second. A number here means part of that 0g came from a sugar alcohol, not a whole food.
• Read the first three ingredients. Whole-food sweeteners (like dates) sit near the top of a short list. Extracts and alcohols often show up alongside several other processed ingredients.
• Don't confuse "no added sugar" with "sugar-free." A whole-food-sweetened bar can have natural sugar and still legitimately carry a "no added sugar" claim — that's not a contradiction, it's how the label is defined.

Frequently Asked Questions

Does "no added sugar" mean the same thing as sugar-free?

No. "No added sugar" means no sugar was added during processing, based on the FDA's Added Sugars line on the Nutrition Facts panel. "Sugar-free" is a different, stricter claim about total sugar content. A protein bar sweetened with a whole food like dates can be "no added sugar" while still containing natural sugar — that's not a contradiction, it's how the two terms are defined differently.

Is "no added sugar" the same as "low sugar"?

No — they answer different questions. "Low sugar" is about the total amount of sugar in the bar; "no added sugar" is only about whether sugar was added during processing, shown on the Added Sugars line. A bar sweetened with a whole food like dates can correctly claim "no added sugar" while still carrying natural sugar from the fruit, so it won't always meet a strict "low sugar" threshold. If you're comparing bars, decide which question actually matters to you first: no added sugar, or low total sugar.

Can a protein bar say "0g added sugar" and still contain sugar alcohols?

Yes. Sugar alcohols like erythritol and maltitol, along with the rare sugar allulose, are not counted as "added sugars" under current FDA labeling rules, so a bar can legitimately show 0g Added Sugars while relying on them for sweetness. Checking the separate Sugar Alcohol line on the label — not just the Added Sugars line — is the only way to catch this.

Are dates considered added sugar on a nutrition label?

No. Dates are a whole fruit, and the FDA does not classify sugar that occurs naturally in whole fruit as "added sugar." A protein bar sweetened entirely with dates, like every That's All Protein bar, correctly shows 0g on the Added Sugars line even though it has natural sugar from the fruit itself.

What should I check on a protein bar label to verify a "no added sugar" claim?

Check three things: the Added Sugars line (should read 0g), the Sugar Alcohol line (a number here means the claim relies partly on a sugar alcohol), and the first few ingredients (a whole food like dates near the top is a good sign; an unfamiliar extract or alcohol is worth looking up). That's All Protein calls this the 3-Line Label Check, and every one of its bars passes it using organic dates as the sole sweetener.

Why do some "no added sugar" protein bars still cause bloating?

Usually because their 0g Added Sugars claim comes from a sugar alcohol rather than a whole food. Per FDA food labeling guidance on sugar alcohols, these are poorly absorbed by the small intestine and can ferment in the colon, a documented mechanism behind gas and bloating for some people — covered in more depth in That's All Protein's guide to protein bars without sugar alcohols. A bar with no added sugar AND no sugar alcohols — which is how every That's All Protein bar is formulated — avoids that specific mechanism.

Final Verdict

"No added sugar" is a real, FDA-defined label claim — but it's not a single guarantee about how a bar got there. The fastest way to know what you're actually buying is the 3-Line Label Check: look for 0g on the Added Sugars line, confirm there's no separate Sugar Alcohol number doing the work instead, and see whether the sweetness comes from a whole food you recognize. That's All Protein bars pass all three, using organic dates as the only sweetener across all flavors — no sugar alcohols, no allulose, no added sugar of any kind. Try all three flavors in the variety pack and check the label yourself.
