NHS Daily Sugar Limits at a Glance
Free Sugar vs Naturally Occurring Sugar
Not all sugar is treated equally by health guidelines. The NHS daily limit applies specifically to free sugars — not all sugars in your diet.
🔴 Free Sugars — Count Towards Your Daily Limit
Any sugar added to food or drink during manufacturing, cooking, or at the table. Also includes sugars naturally present in honey, syrups, fruit juices, and fruit juice concentrates. These are the sugars the NHS wants you to cut back on.
Examples: table sugar, glucose syrup, honey, maple syrup, fruit juice, soft drinks, ketchup, cereal.
🟢 Naturally Occurring Sugars — Do Not Count
Sugars naturally present in whole fruits, vegetables, and milk (lactose). These come packaged with fibre, vitamins, and minerals that slow absorption and benefit health. The NHS does not recommend limiting these.
Examples: an apple, a banana, plain milk, plain natural yoghurt, vegetables.
This is why a glass of orange juice and a whole orange are treated differently, even though both contain fructose. Juicing removes fibre, turning naturally occurring sugars into free sugars.
Why Does Too Much Sugar Matter?
Consuming too many free sugars is linked to several health problems in the UK:
🦷 Tooth Decay
Tooth decay is the most common childhood disease in England, and the leading cause of child hospital admissions. Sugar feeds bacteria in the mouth that produce acids, which erode tooth enamel. Every time sugar is consumed, there is an "acid attack" lasting around 20 minutes.
⚖️ Weight Gain & Obesity
Sugary foods and drinks are energy-dense and tend to be low in fibre, meaning they don't fill you up but add significant calories. Liquid sugar in particular — from soft drinks, juices, and energy drinks — is especially problematic as the body registers liquid calories less effectively than solid food.
🩺 Type 2 Diabetes & Heart Disease
High sugar intake, especially from sugary drinks, is associated with increased risk of type 2 diabetes and cardiovascular disease, both of which are major causes of premature death in the UK. The link is partly direct and partly through the intermediary of weight gain and obesity.
Reading a UK Food Label
UK food labels must show total sugars per 100g or 100ml, and many also show per serving. Here is what to look for:
Traffic Light Labels
Many UK products use a front-of-pack traffic light system. For sugar: Red = High (more than 22.5g per 100g or more than 27g per portion) · Amber = Medium (between 5g and 22.5g per 100g) · Green = Low (5g or less per 100g).
Hidden Names for Sugar on Ingredient Lists
Sugar is listed under many names. Anything ending in "-ose" is a sugar (glucose, fructose, lactose, sucrose, dextrose, maltose). Others include: corn syrup, golden syrup, treacle, agave nectar, rice syrup, fruit juice concentrate, molasses, honey, and invert sugar. The earlier in the ingredient list a name appears, the more of it there is in the product.
Per 100g vs Per Serving
Always check both columns on a label. A product might seem low in sugar per 100g, but if a realistic serving is 200g or 300g, the actual sugar consumed can be much higher. Manufacturers sometimes list unrealistically small serving sizes to make the sugar content appear lower.
