Why Low-Sugar Products Still Spike Your Levels

Free Sugars vs. Matrix-Bound Sugars: What This Means and Why It Matters

Side-by-side comparison of free sugars versus matrix-bound sugars showing how absorption speed differs

Products with only 3–5g sugar can still spike your levels if they contain “free sugars” as opposed to “matrix-bound” sugars.

“Matrix-bound sugars”? What does that even mean?

If this is the first time you’re hearing this, you aren’t alone. Until I started investigating why even one date had an adverse effect on me, I hadn’t heard of it either. Even after 20 years of eating carefully and avoiding sugars, I didn’t know why I had to stay away from date and coconut sugar sweetened treats. I simply knew they spiked my levels even though the overall sugar content on the label was low, and I knew that the 1g of sugar in my homemade chocolate spread didn’t feel the same. Turns out coconut butter, almond butter, and the like have “matrix-bound” sugars — and that is why the sugar didn’t hit my system the way coconut sugar does.


The Difference Between Free Sugars and Matrix-Bound Sugars

Free sugars are exactly what they sound like — sugars that are unbound, unencased, and ready to hit your bloodstream the moment digestion begins. This includes honey, agave, date sugar, coconut sugar, and most sweeteners marketed as natural alternatives. Even in small amounts — 3 to 5 grams — free sugars can spike your levels, because quantity isn’t the only variable. Speed of absorption is.

Matrix-bound sugars behave differently. In a whole food, sugars are encased within the cellular structure of the food itself — surrounded by fiber or raw plant fats. That physical matrix acts as a barrier. Digestive enzymes have to work through the cell walls before they can access the sugar, and the fat present simultaneously slows gastric emptying — the rate at which food moves from your stomach into your digestive tract. The result is that sugar enters your bloodstream more slowly and in smaller amounts than the label alone would suggest.

Free sugars — the kind found in honey, agave, date sugar, and coconut sugar — can spike your levels even in small amounts.

Matrix-bound sugars — the kind found in whole foods and raw plant fats like nuts, nut butters, and coconut butter — are slowed by the fat and fiber matrix surrounding them, so your body processes them gradually rather than all at once.


What Free Sugars Actually Do to Your Body

The conversation around free sugars usually stops at blood sugar. But what’s happening is more layered than that.

When free sugars enter the bloodstream, the pancreas secretes insulin to drive glucose into cells. If more glucose is present than cells can use, the liver converts the excess first to glycogen for short-term storage — and when those stores are full, to triglycerides, which is body fat. This is the direct metabolic mechanism behind sugar-driven weight gain.

Then there’s the fructose pathway, which is more significant than many people realize. Honey, date sugar, and coconut sugar all contain meaningful amounts of fructose. Unlike glucose, fructose is metabolized almost exclusively by the liver, bypassing the normal insulin response entirely. The liver converts fructose directly into fat — contributing specifically to visceral fat and, with chronic consumption, placing stress on the liver itself.

The hormonal effects compound this. Fructose does not trigger leptin, the satiety hormone — so your brain doesn’t receive a reliable “full” signal after eating free sugars the way it does after eating fat or protein. Ghrelin, the hunger hormone, is also not suppressed by fructose. This is why free sugars are uniquely associated with ongoing hunger even after consuming calories. The insulin spike itself is followed by a drop — sometimes a crash — that the adrenal glands respond to by releasing cortisol to stabilize blood glucose. Repeated crashes mean repeated cortisol hits, which over time drive abdominal fat storage and place ongoing stress on the adrenal system.

For those managing candida, the picture is even clearer: Candida albicans feeds on free sugars directly. The organism does not distinguish between honey and refined sugar. This is why even small amounts of “natural” sweeteners remain problematic for that community.


A Note on Dates Specifically

Whole dates occupy an interesting middle position. They are technically matrix-bound — the sugar exists within the cellular structure of the fruit alongside fiber. But that fiber binding slows sugar absorption only modestly compared to fat binding, which is why even whole dates can be spikey for sensitive people. Date paste or purée is a different matter entirely: the processing breaks down the fiber matrix, making the sugar behave nearly equivalently to a free sugar despite the whole-food origin. This is worth watching on labels — date paste and date syrup are increasingly common in products marketed as refined-sugar-free.


What About Fruit?

The discussion about fructose above is not meant to say fruit is off limits — at least not for everyone. I personally can’t eat it. Even a single piece spikes my blood sugar, leaves me hungry once it passes through my stomach, and feeds candida. But my system is particularly sensitive, and that’s not everyone’s experience.

For those less sensitive, whole fruit eaten in its intact form is a reasonable choice. The sugar in whole fruit is matrix-bound — encased within cell walls alongside fiber and water, which meaningfully blunts absorption compared to processed forms. Some food combining traditions also allow certain fruits — particularly sub-acid fruits like berries and apples — to be eaten with nuts or dairy, which happens to align with what we know about fat slowing sugar absorption.

What tends to cause problems, even for less sensitive people, is fruit in forms that destroy the matrix: juiced, blended completely smooth, dried, or puréed. Fresh-pressed juice, regardless of how natural or cold-pressed, is essentially liquid sugar — the fiber matrix that would have slowed absorption is gone. Smoothies fall somewhere in between depending on how thoroughly they’re blended. Dried fruit concentrates the sugar dramatically by removing the water, overwhelming whatever fiber remains.


Why This Matters for What You Eat Every Day

The practical implication of all of this is that label reading tells you only the sugar count, not its behavior. Three grams of free sugar — from agave, honey, or date syrup — can behave very differently in your body than three grams of sugar present in intact nuts, seeds, or coconut butter.* One is a signal your body processes gradually. The other hits all at once and is processed in a way that can contribute to spikes, weight gain, and hunger after caloric intake.

Worth noting: most 1g and 0g treats rely on erythritol or maltitol. Monk fruit is frequently blended with one of these — but pure monk fruit extract is its own thing entirely. No sugar alcohols, nothing artificial.

These are the distinctions that keeps me committed to Delessa — because I believe people who react to free sugars deserve a product formulated with that understanding from the ground up.

*Coconut butter — the base for our Concordia’s Sweet Chocolate Profusion — holds its sugars in a particularly effective matrix. Not only is absorption significantly slowed by being bound to raw plant fats, but coconut butter also contains inulin, a prebiotic fiber that feeds beneficial gut bacteria and further slows digestion by passing through the small intestine intact. Note to those managing SIBO or other FODMAP sensitivities: you may find inulin difficult to tolerate, as its fermentable nature — the same property that makes it beneficial for many — may not work for you.

Frequently Asked Questions

Is Delessa sweetened with only monk fruit — no erythritol?

Yes. We use a small amount of 100% pure monk fruit extract to complement the natural, matrix-bound sweetness of our whole-food ingredients. Delessa contains absolutely no erythritol, and no sugar alcohols. Unlike most products labeled “monk fruit sweetened,” we never blend our extract with erythritol, xylitol, or other sugar alcohols. Pure monk fruit extract stands entirely on its own — no bulking agents, no artificial aftertaste, no shortcuts.

Does pure monk fruit extract feed candida?

No. Pure monk fruit extract contains zero sugars and zero carbohydrates, so it cannot feed candida or yeast overgrowth. The important distinction is purity — most commercial “monk fruit sweeteners” are blended with erythritol, or they contain hidden free sugars like date paste which will feed candida. Delessa uses only pure extract within a matrix-bound whole-food structure.

Does date paste spike blood sugar?

Yes — for sugar-sensitive individuals, even small amounts can cause a rapid glucose spike. Whole dates are technically matrix-bound, but the blending process used to make date paste ruptures the cellular structure, releasing sugars that now behave as free sugars. Your body no longer has to work through the plant cell walls to access them, so absorption is fast regardless of the small serving size. Delessa doesn’t use date paste for exactly this reason.

Does date paste count as added sugar?

No - not on a US nutrition label — the USDA allows brands to omit date paste from the Added Sugars line because it derives from whole fruit. But biologically it behaves like an added sugar. Once the cellular matrix is broken down by processing, the resulting paste is handled by your liver and metabolism the same way refined sugar is. The WHO classifies fruit juices and fruit juice concentrates as free sugars for this reason. The UK’s Scientific Advisory Committee on Nutrition goes further, explicitly classifying blended, pulped, and puréed fruit the same way — because the cellular structure has been broken down and the sugar no longer behaves as it would in its intact, whole-food form. The label won’t tell you this, which is why it matters to understand what date paste actually is before it reaches your bloodstream.

Why do low-sugar products still spike glucose?

Usually because the sugars they contain are free sugars — unbound, fast-absorbing, and not reflected accurately by the gram count on the label. Three grams of free sugar from agave, date syrup, or honey absorbs very differently than three grams of sugar present within an intact nut or coconut matrix. Some products compound this with processed fiber additives like soluble corn fiber or resistant dextrin, which the label doesn’t count as sugar but which can break down into glucose in the body. The number on the label tells you how much sugar is present. It doesn’t tell you how fast it hits.
