Honey vs Refined Sugar and Its Gentler Effect on Blood Glucose

Sugar is the first thing most people cut when they get serious about metabolic health, and for good reason. Honey, though, is a more interesting molecule than table sugar, and a growing body of research says it affects blood glucose differently, and often more gently, than refined sugar does. In a 2018 review in Oxidative Medicine and Cellular Longevity, Bobiş and colleagues pulled this evidence together [1], and a 2024 book chapter on honey as an antidiabetic agent reached broadly similar conclusions [5].

Honey is sugar, but not the same sugar

Honey is a caloric sweetener, and it raises blood glucose, so it's not a free pass. Table sugar, or sucrose, is a tidy 50/50 bond of glucose and fructose. Honey is a looser mix of free fructose and glucose, water, and small amounts of minerals, enzymes, organic acids, and antioxidant compounds called polyphenols.

That composition gives honey a lower glycemic index, the measure of how fast and how high a food pushes blood sugar. Honey lands around 58, compared with about 60 for table sugar and 100 for pure glucose, while fructose on its own sits near 19 [1]. So gram for gram, honey tends to raise blood sugar a little less sharply than the usual sweeteners.

What happens in the body

The most direct human comparison came from a 2004 study where Al-Waili gave healthy people, people with diabetes, and people with high cholesterol either honey, dextrose (pure glucose), or sucrose, then tracked their blood. Honey produced a smaller rise in blood glucose than dextrose, prompted a greater release of insulin and C-peptide (a marker that your pancreas is making insulin), and lowered markers of inflammation and blood fats [2].

Why would a sweet food blunt the glucose response? The leading explanation centers on fructose. In the liver, fructose flips on an enzyme called glucokinase, which pulls glucose out of the bloodstream and stores it as glycogen. A modest amount of fructose, like the amount in honey, can nudge the body to take up glucose more efficiently, an effect Erejuwa and colleagues describe as the catalytic or fructose effect [3]. Honey's minerals and antioxidants may add to this by easing the oxidative stress that wears down an overworked pancreas [1].

What longer studies show

Over a longer stretch the picture is mixed. In an 8-week randomized trial in people with diabetes, Bahrami and colleagues found that natural honey trimmed body weight and improved blood lipids compared with no honey, which are real wins. The same trial, though, saw a rise in HbA1c, a measure of average blood sugar over the prior few months, which is a clear caution flag [4]. That tension runs through this whole field. Honey looks better than refined sugar on several measures, yet it's still sugar, and people with diabetes who add too much of it can push their long-term numbers the wrong way.

How to think about it

This means that if you're going to use a sweetener, a small amount of raw honey is a better choice than refined sugar. It raises blood sugar a little less, it brings antioxidants and trace minerals instead of empty calories, and the body seems to process it more gracefully. None of that turns honey into a health food you can pour freely, and none of it makes honey a treatment for diabetes.

If you have insulin resistance or diabetes, keep portions small, watch how your own glucose responds (a finger-stick reading or a continuous glucose monitor tells the real story), and never swap honey in for a medication your physician prescribed. Used with that respect, honey is one of the better ways to keep a little sweetness in your life.
