Honey vs Sugar: What Actually Differs

Honey and table sugar differ in composition, in weight per spoon and in how they behave in a pan — but not in the category UK dietary guidance puts them in. The NHS counts the sugars in honey among free sugars, alongside table sugar and syrups, and advises that adults have no more than 30 g of free sugars a day. The rest of the comparison is checkable: what each is made of, what a teaspoon of each weighs, and where the two part company in a kitchen.

Honey is roughly 82% sugars — chiefly fructose and glucose, already separate — and about 17% water, with minerals in trace amounts. Granulated sugar is sucrose: glucose and fructose bonded together, at 99.8 g per 100 g, with essentially no water.

Is honey better than sugar?

Not in the sense the question is usually asked. On the one measure UK dietary guidance applies, the two sit in the same bracket. The NHS defines free sugars as sugars added to food or drink plus “sugars in honey, syrups (such as maple, agave and golden), nectars (such as blossom), and unsweetened fruit juices, vegetable juices and smoothies”, and notes that sugar found naturally in milk, fruit and vegetables does not count. The adult guideline is no more than 30 g of free sugars a day.

That is the ceiling on this comparison; everything below is about what is in the jar and what happens in the pan. For the published research on honey — what has been studied, and what those studies did and did not show — we keep a separate record in our evidence section.

What is honey made of, and what is table sugar made of?

USDA reference data, per 100 g:

Two things stand out. The first is water: about a sixth of honey is water, which is why one is a syrup and the other a crystal, and why they do not swap cleanly.

The second is where the sugars sit. Honey’s arrive already split into fructose and glucose — the bees’ invertase does that in the hive — leaving under 1 g of sucrose per 100 g. Granulated sugar is the opposite: essentially all sucrose, the two simple sugars still joined. That is not a quirk of one sample. The Honey (England) Regulations 2015 require blossom honey sold in England to carry not less than 60 g/100 g of fructose and glucose combined, and for most honey not more than 5 g/100 g of sucrose and not more than 20% water — Schedule 1 sets a higher sucrose limit of 10 g/100 g for named varieties such as false acacia, alfalfa, red gum, leatherwood and citrus, 15 g/100 g for lavender and borage, and a higher moisture limit of 23% for heather honey.

The minerals are real and tiny: potassium, the most abundant, runs to 52 mg per 100 g — about 3.6 mg in a teaspoon.

The ceiling on this comparison

No more than 30 g of free sugars a day for adults. Five teaspoons of honey come to roughly 29 g, and seven teaspoons of granulated sugar to roughly 29 g. That is arithmetic, not advice.

How many calories are in a teaspoon of honey?

About 21 kcal — and the arithmetic behind it is the most useful thing on this page, because per-gram and per-spoon comparisons point in opposite directions.

Honey is 304 kcal per 100 g; granulated sugar is 387 kcal per 100 g. So per gram, honey carries about a fifth fewer calories — 3.04 against 3.87 — because about 17% of it is water and none of the sugar is.

Now weigh a spoon. USDA gives a tablespoon of honey as 21 g, so a teaspoon is 7 g; a level teaspoon of granulated sugar is 4.2 g. The honey spoonful weighs about two-thirds more:

• a teaspoon of honey: 7 g, about 21 kcal, about 5.7 g of sugars
• a teaspoon of granulated sugar: 4.2 g, about 16 kcal, 4.2 g of sugars
• a tablespoon of honey: 21 g, about 64 kcal, about 17 g of sugars

The cup weights agree: 339 g of honey against 200 g of granulated sugar, the same 1.7-to-1 ratio.

So per spoon, honey carries about 30% more calories than sugar, and per gram about 20% fewer. Both are true, and a comparison quoting only one of them is choosing. Against the 30 g adult free-sugars guideline, five teaspoons of honey come to roughly 29 g, and seven teaspoons of granulated sugar to roughly 29 g. That is arithmetic, not advice.

What the calorie figures do and do not show

They are figures about a jar, not about a diet. What was measured is this: 3.04 kcal per gram against 3.87, about 21 kcal a teaspoon against about 16, and both sets of sugars inside the NHS free-sugars category.

What does honey bring to a kitchen that sugar cannot?

Flavour, and this is the only argument this page makes.

Granulated sugar is one compound doing one job: sweetness with nothing attached, which is exactly why it is useful. Honey tastes of where it came from — the nectar of one hillside in one flowering, carrying aroma compounds sugar does not have. Cretan thyme honey is amber and intensely herbal with a savoury edge; a pine honey is dark and resinous. Stirred into a mug of tea that character is largely wasted: the sweetness barely changes and the aroma leaves with the steam. On yoghurt, on cheese, over roast vegetables, honey does something sugar cannot.

Aroma is also the fragile part: FAO notes that honey stored above 25 °C stays liquid but loses much of its aroma within months. How a honey is handled between hive and jar decides how much reaches you — see what raw honey is and raw vs pasteurised honey.

What changes when you bake with honey instead of sugar?

Three differences, all of them physical.

Water. Honey is 17.1 g of water per 100 g; granulated sugar is 0.02 g. Substituting one for the other adds liquid, and a recipe balanced for a dry crystal is not balanced for a syrup. By volume the gap widens: a cup of honey is 339 g to sugar’s 200 g.

Hygroscopicity. FAO calls honey “strongly hygroscopic”: at a water content of 18.3% or less it draws moisture out of the air above 60% relative humidity, reaching 24.2% water at 70%. In a kitchen that cuts both ways — bakes made with honey hold their moisture longer, and an open jar in a steamy room takes water on.

Heat. Honey’s aroma compounds are volatile, so long or hot cooking costs a honey the character you chose it for; where flavour is the point, honey goes in last. The laboratory markers for heating and age are HMF, capped in UK law at 40 mg/kg for most honey, and diastase activity, with a floor of 8 on the Schade scale in the same schedule (3 for naturally low-enzyme honeys such as citrus, and only where HMF is not above 15 mg/kg).

Who should not eat honey?

Honey of any kind is not suitable for infants under 12 months. NHS advice is not to give honey to a child until they are over one year old, because honey occasionally contains bacteria that can produce toxins in a baby’s intestines, leading to infant botulism, a very serious illness. Bee products are also allergens for some people; both are facts about the category.

Where THYMELIA stands

THYMELIA is a UK house of Greek foods working two harvests — raw thyme honey from Chania in western Crete, and early-harvest olive oil from the hills above Kalamata. We sell food. Honey is a sugar and UK guidance counts it as one; what the studies on honey actually measured is at evidence.

The case we make is the kitchen one above: a single-origin honey whose flavour comes from wild thyme flowering on the hills of western Crete from May to July, extracted once as the bloom closes. There is no shop yet, and we name no date for one. Not everything the house offers will be raw — where we use the word it will be evidenced per batch. How we source is at sourcing; what we test and publish is at testing.

The category from the top is at raw honey.
