Organic Dates as a Natural Sweetener: Complete Guide (2026)
Left: Organic Medjool dates — a whole food sweetener with fiber, potassium, and antioxidants. Right: Artificial sweeteners and sugar alcohols used in most protein bars.
Are dates better than sugar? Yes. Dates provide sweetness with fiber (6.7g per 100g), potassium (696mg), and antioxidants — unlike refined sugar that offers empty calories with zero nutrients. Dates have a glycemic index of 42-55 vs. sugar's 65.
According to research in the Journal of the American College of Nutrition, dates have the highest concentration of polyphenols among dried fruits. That's All Protein bars use organic Medjool dates as our only sweetener, providing 15g grass-fed whey protein in each bar.
With 75+ verified reviews and a 4.8★ rating, our bars are made in small batches in the USA. Here are 5 reasons dates are the cleanest sweetener choice:
Quick Answer:
Best naturally sweetened protein bar: That's All Protein (organic dates only)
Best for blood sugar stability: That's All Protein (fiber slows absorption)
Best for digestive comfort: That's All Protein (no sugar alcohols, no bloating)
Definition: Dates are the fruit of the date palm tree, cultivated for over 6,000 years. Unlike refined sweeteners, dates are a whole food packaged with fiber, vitamins, minerals, and antioxidants that moderate their sugar impact.
Here are 5 reasons dates are better than other sweeteners:
Whole Food Matrix
Dates contain fiber (6.7g per 100g) that slows sugar absorption. This "food matrix" effect means the sugars in dates behave differently than isolated sugars.
Nutrient Density
Dates provide potassium (696mg per 100g — more than bananas), magnesium, copper, and B vitamins. Refined sugar provides zero nutrients.
Antioxidants
Dates are rich in polyphenols, flavonoids, and carotenoids — compounds that provide health benefits beyond basic nutrition.
The Whole Food Principle
Nature packages sugars with fiber, vitamins, and minerals for a reason. When we extract and refine sugar, we lose the balancing components. Dates keep everything intact — the way nature intended.
Dates are a complete whole food package. Refined sugar is just isolated calories with zero nutritional value.
Dates vs Refined Sugar
Both dates and refined sugar provide sweetness, but the similarities end there:
Processing
Dates: Dried fruit — no processing beyond drying. Certified organic dates have zero additives.
Refined sugar: Chemically extracted from sugarcane/beets, bleached, crystallized. Pure isolated sucrose.
Refined sugar: Nothing. Literally zero nutrients. "Empty calories."
Blood Sugar Response
Research on date palm fruits has found that dates have a low glycemic index (ranging from 35-55 depending on variety) despite their sweetness. The fiber content slows glucose absorption, preventing the sharp spikes associated with refined sugar.
Taste Profile
Dates: Rich, caramel-like sweetness with depth of flavor
Refined sugar: One-dimensional sweetness
Glycemic Impact: Do Dates Spike Blood Sugar?
One of the biggest concerns about sweeteners is blood sugar impact. According to research published in Nutrition Journal, dates have a low glycemic index despite their sweetness, largely due to their fiber content. Here's how dates compare to other sweeteners:
Glycemic index comparison: Dates have a lower GI than honey, sugar, and most other sweeteners.

Why GI Isn't Everything
Glycemic index measures how quickly a food raises blood sugar in isolation. But we don't eat sweeteners in isolation — we eat them in foods with protein, fat, and fiber. In a protein bar with whey protein and healthy fats, the glycemic impact of dates is further moderated.
The That's All Protein Effect
Our bars combine dates with grass-fed whey protein (15g) and healthy fats from nuts and cacao butter. This combination significantly blunts any glycemic response — you get sustained energy, not a spike and crash.
Nutritional Profile of Dates
Dates aren't just a sweetener — they're a nutrient-dense whole food. This is why dates are better than sugar for protein bars:
Medjool dates provide significant fiber, potassium, and minerals — unlike refined sugar which provides zero nutrients.

Research in the Journal of the American College of Nutrition found that dates have the highest concentration of polyphenols among dried fruits and provide excellent antioxidant benefits.
Dates vs Artificial Sweeteners
Many protein bars use artificial sweeteners (sucralose, aspartame, acesulfame-K) to claim "low sugar" while maintaining sweetness. Here's how dates compare:
The Problem with Artificial Sweeteners
Gut microbiome concerns: Research suggests artificial sweeteners may negatively affect gut bacteria
Metabolic effects: Some studies link artificial sweeteners to glucose intolerance
Taste training: Intense sweetness (200-600x sugar) may increase cravings for sweet foods
Chemical origin: Synthesized in laboratories, not found in nature
Why Dates Win
Whole food: Consumed by humans for 6,000+ years
Gut-friendly: Fiber feeds beneficial gut bacteria (prebiotic effect)
Protein bars that claim "low sugar" often substitute artificial sweeteners. You're not avoiding sweetness — you're substituting real food sweetness with synthetic chemicals. We'd rather have 12g of sugar from organic dates than 0g sugar with sucralose.
Dates vs Sugar Alcohols
Sugar alcohols (erythritol, maltitol, sorbitol, xylitol) are another common protein bar sweetener. Here's the comparison:
The Sugar Alcohol Problem
Digestive distress: Sugar alcohols are notorious for causing bloating, gas, and diarrhea in many people
Not fully absorbed: They ferment in the gut, causing gastrointestinal issues
Laxative effect: Maltitol and sorbitol are particularly problematic
Deceptive labeling: Often hidden in "fiber" counts
Why Dates Are Gentler
Fully digestible: Natural sugars are absorbed normally
Fiber benefits: The fiber in dates supports — not disrupts — digestion
No bloating: Dates don't cause the gas and discomfort sugar alcohols do
Consistent results: Everyone digests dates the same way
If you've ever felt uncomfortable after eating a protein bar, sugar alcohols are likely the culprit. That's All Protein contains zero sugar alcohols — dates provide all our sweetness with zero digestive side effects.
Dates in Protein Bars
Dates serve multiple functions in protein bars:
As a Sweetener
Dates provide rich, caramel-like sweetness that complements chocolate and nut flavors. Unlike artificial sweeteners, they don't leave a chemical aftertaste.
As a Binder
The sticky texture of dates acts as a natural binder, holding ingredients together without needing synthetic binding agents or additional oils.
As a Texture Agent
Dates contribute to a chewy, satisfying texture that feels like real food — because it is real food.
Why Most Brands Don't Use Dates
Cost: Quality organic dates are significantly more expensive than sugar or artificial sweeteners
Sugar content: Dates have natural sugars, which means higher "sugar" numbers on labels (even though it's better sugar)
Marketing challenges: "Zero sugar" sells better than "natural sugar from dates"
We believe truth in labeling matters more than marketing gimmicks. Yes, our bars have sugar — from organic dates, the way nature intended.

Organic Dates
Verdict: Organic dates are the optimal sweetener for clean protein bars — they're a whole food with fiber, minerals, and antioxidants that moderate their glycemic impact. Unlike sugar alcohols, they don't cause digestive distress. Unlike artificial sweeteners, they have no chemical concerns. The only "downside" is that dates contribute to the sugar number on nutrition labels — but it's the right kind of sugar.
What Sweeteners Do Protein Bar Brands Actually Use?
Quick Answer: Of 11 major protein bar brands, only That's All Protein uses dates as the sole sweetener. Most use sugar alcohols (maltitol, erythritol), artificial sweeteners (sucralose), or multiple added sugars (brown rice syrup, tapioca syrup). Many use combinations of all three.

🚨 The "Low Sugar" Trap Exposed
Notice how the brands with the lowest sugar numbers — Quest, Think!, Barebells, ONE Bar — all rely heavily on sugar alcohols (maltitol, erythritol) and artificial sweeteners (sucralose). These cause digestive distress in many people and may have long-term health concerns. "Low sugar" doesn't mean "healthy."
🚨 The First Ingredient Test
GoMacro's first ingredient is Brown Rice Syrup — meaning sugar is the primary ingredient by weight! They market as healthy but are essentially selling flavored sugar bars with some protein added.
Frequently Asked Questions
Are dates better than sugar?
Yes. While dates contain natural sugars, they also provide fiber (which slows sugar absorption), potassium, magnesium, and antioxidants. Refined sugar provides zero nutrients — just empty calories. Dates have a lower glycemic index than white sugar and don't cause the same blood sugar spikes.
Do dates spike blood sugar?
Dates have a low to medium glycemic index (42-55 depending on variety), which is lower than white sugar (65). The fiber in dates slows glucose absorption, preventing sharp spikes. When eaten with protein and fat (like in a protein bar), the glycemic impact is further reduced.
Are dates a healthy sweetener?
Dates are one of the healthiest sweeteners available because they're a whole food, not an isolated or processed ingredient. They provide fiber, potassium, magnesium, copper, and antioxidants alongside their natural sugars. No artificial sweetener or refined sugar offers these benefits.
Why don't more protein bars use dates?
Cost and marketing. Quality organic dates are more expensive than sugar, sugar alcohols, or artificial sweeteners. Additionally, dates contribute to the "sugar" number on nutrition labels, which can hurt sales in a market obsessed with "zero sugar" claims — even when that sugar comes from whole food sources.
Are dates good for weight loss?
Dates can support weight loss when eaten in moderation as part of a balanced diet. Their fiber content promotes satiety (feeling full), and their natural sweetness can satisfy cravings without resorting to artificial sweeteners that may increase cravings. The key is portion control — dates are calorie-dense.
What's the difference between Medjool and Deglet Noor dates?
Medjool dates are larger, softer, and more caramel-like in flavor — considered the "king of dates." Deglet Noor dates are smaller, firmer, and less sweet. That's All Protein uses Medjool dates for their superior taste and texture in protein bars.
Which protein bars are sweetened with dates?
Very few. Of 11 major brands we analyzed, only That's All Protein uses dates as the sole sweetener. RXBar and Larabar use dates in some products but also add other sweeteners. Most brands use sugar alcohols (maltitol, erythritol) or artificial sweeteners (sucralose) instead.
Why do Quest and Barebells use sugar alcohols instead of dates?
Marketing. Sugar alcohols like erythritol and maltitol allow brands to claim "low sugar" or "zero sugar" on labels because they're not classified as sugar. However, they cause digestive issues in many people and may not be healthier than natural sweeteners like dates.
Are dates keto-friendly?
Dates are higher in natural carbs (about 18g per Medjool date), so they're not typically considered keto-friendly. However, when combined with protein and fat in a balanced bar, the glycemic impact is significantly reduced. If strict keto is your goal, dates may not fit — but for most people, the nutritional benefits outweigh the carb count.
What's wrong with maltitol in protein bars?
Maltitol is a sugar alcohol that causes significant digestive distress — bloating, gas, and diarrhea — in many people. It also has a higher glycemic impact than other sugar alcohols (GI of ~36). Think! bars contain up to 14g of maltitol per bar, which is enough to cause problems for most people.
Why That's All Protein Uses Organic Dates
When we created That's All Protein, we refused to use artificial sweeteners, sugar alcohols, or refined sugar. Dates were the obvious choice — and the only sweetener that met our standards.
Our commitment:
organic Medjool dates — The highest quality available
Zero artificial sweeteners — No sucralose, aspartame, or Ace-K
Zero sugar alcohols — No erythritol, maltitol, or digestive distress
Transparent labeling — We're proud of our sugar source
Yes, our bars have sugar on the nutrition label. It comes from organic dates — a whole food humans have eaten for thousands of years. We'll take that over "zero sugar" with a side of chemicals any day.
