5 min read

According to the British Nutrition Foundation, average free sugar consumption in the UK significantly exceeds recommended intakes across all age groups. Many are unaware of what are the hidden sugars in foods UK, which are often concealed in processed products marketed as healthy.

Quick Summary

Hidden sugars are added to many processed UK foods, from sauces to low-fat products, under a variety of names. Consumers can learn to identify these 'free sugars' by reading ingredient lists and food labels to make more informed dietary choices.

Key Points

  • Hidden Sugar Names: Be aware of over 50 different names for sugar used by manufacturers, including sucrose, glucose, maltose, and fruit juice concentrate.

  • Ubiquitous in Processed Foods: Hidden sugars are prevalent in surprising products like pasta sauces, low-fat yogurts, cereal bars, and salad dressings.

  • Label Reading Skills: Use the UK's traffic light system and check ingredient lists, where sugar appears higher up the list in high-sugar products.

  • Misleading Marketing: Don't be fooled by terms like 'no added sugar' or 'natural', which can still indicate a high sugar content from other sources.

Decoding Hidden Sugars in the UK

For many in the UK, a daily diet includes an array of processed and packaged foods, many of which contain surprising amounts of added sugar. These 'hidden sugars,' also known as 'free sugars,' are added by manufacturers to enhance flavour, texture, and shelf life, often without the consumer's knowledge. Being able to identify these sugars on food labels is a crucial step toward reducing overall intake and improving health. This comprehensive guide will help you understand where hidden sugars lurk, how to spot them, and what simple swaps can be made for a healthier diet.

The Many Names of Sugar on UK Labels

Food manufacturers use over 50 different names for sugar to make it less obvious on ingredient lists. The key is to look for ingredients ending in '-ose' or words that indicate a concentrated syrup or fruit source. Some of the most common terms to watch for include:

  • Sucrose: Standard table sugar.
  • Glucose, Fructose, and Dextrose: Basic sugars often used as sweeteners.
  • High-fructose corn syrup (HFCS): A highly processed sweetener.
  • Maltose: A sugar derived from malt.
  • Molasses and Treacle: Syrups that add sweetness and colour.
  • Honey, Maple Syrup, and Agave Syrup: Naturally occurring but still count as 'free sugars' by UK health guidelines.
  • Fruit Juice Concentrate or Purée: While derived from fruit, the sugars are 'free' once released from the cellular structure.
  • Carob Syrup: A natural sweetener from the carob tree.
  • Barley Malt: A sugar source derived from barley.

Common UK Foods with Hidden Sugars

Many of the items we routinely add to our shopping trolley contain significant amounts of hidden sugar. These are often the products we don't associate with being sweet.

Sauces and Condiments

  • Pasta Sauces: Many shop-bought tomato-based pasta sauces contain added sugar to balance the acidity of the tomatoes. Some jars can contain as much as eight teaspoons of sugar.
  • Ketchup and BBQ Sauce: These condiments are high in added sugars, used for flavour and as a preservative.
  • Salad Dressings: Especially low-fat or sweet French dressings, which can contain a surprising amount of sugar to compensate for the fat reduction.

'Healthy' Breakfast Foods

  • Breakfast Cereals: Even cereals marketed as healthy, like granola and muesli, are often sweetened with honey, maple syrup, or dried fruit.
  • Cereal Bars: Snack and protein bars frequently use a combination of syrups, honey, and dried fruit, which can amount to a very high sugar content.
  • Flavoured Yogurts: A single pot of flavoured, low-fat yogurt can contain as much sugar as a fizzy drink, with added sugar used to boost flavour.

Other Surprising Sources

  • Tinned and Pre-made Soups: Tinned soups, particularly tomato-based varieties, often contain added sugar.
  • Bread: Some mass-produced white and wholemeal breads contain added sugar.
  • Ready Meals: Many pre-packaged meals and meal components can contain added sugars to balance flavours and preserve the food.

How to Read UK Food Labels Effectively

In the UK, food labels are legally required to provide nutritional information, but knowing what to look for is key. The traffic light system on the front of packaging offers a quick guide, with red indicating high sugar content. For a more detailed understanding:

  1. Check the 'Total Sugars' Figure: The nutritional panel on the back of the packaging lists 'Carbohydrates (of which sugars)'. This figure includes both free sugars and naturally occurring sugars (e.g., lactose in milk).
  2. Examine the Ingredients List: Ingredients are listed in descending order of weight. If sugar or one of its many aliases appears near the top of the list, the product has a high sugar content.
  3. Be Wary of Marketing Terms: Claims like 'no added sugar' and 'natural' can be misleading. 'No added sugar' simply means no extra sugar was added beyond the ingredients already containing it (like fruit juice concentrate), while 'natural' is a largely unregulated term.

Comparison Table: Spot the Sugar

To illustrate the difference, here is a comparison of common products with high and low hidden sugar content.

Product Category High Sugar Example (per serving) Approx. Sugar (g) Lower Sugar Alternative Approx. Sugar (g)
Breakfast Granola with honey and dried fruit 15-20g Plain porridge with fresh berries 5-10g
Yogurt Low-fat fruit yogurt (125g pot) >15g Plain Greek yogurt with fresh fruit <10g (mostly natural)
Drink 200ml fruit juice ~20g 200ml water with a slice of lemon <1g
Condiment Tomato Ketchup (1 tbsp) ~4g Home-made tomato sauce (1 tbsp) ~2g
Snack Cereal bar with honey 10-12g A handful of unsalted nuts <1g

The Health Consequences of Excessive Sugar Intake

Consuming too many free sugars can have significant, long-term impacts on health, even leading to serious conditions.

  • Weight Gain and Obesity: Free sugars provide 'empty calories' that are easily over-consumed, leading to excess energy intake and weight gain.
  • Type 2 Diabetes: High intakes of free sugars, especially from sugary drinks, are strongly linked to an increased risk of developing Type 2 diabetes.
  • Heart Disease: Excess sugar intake can raise blood triglycerides, a known risk factor for cardiovascular disease.
  • Dental Decay: Sugar is a primary cause of tooth decay, a particular concern for children.
  • Fatty Liver Disease: Excessive fructose is metabolised by the liver, and high consumption can overload it, leading to non-alcoholic fatty liver disease.

Making Healthier Choices

Reducing your intake of hidden sugars is a straightforward process once you know what to look for. By prioritising whole, unprocessed foods and being mindful when shopping for packaged goods, you can significantly cut down on your sugar consumption.

Here are some actionable tips:

  • Cook from Scratch: Preparing your own meals allows you complete control over ingredients, including the amount of sugar added.
  • Choose Plain over Flavoured: Opt for plain yogurts, porridge, and water, adding your own fresh fruit for sweetness.
  • Be Label Savvy: Always turn the package over and read the ingredients list. Remember the numerous names for sugar and their order of appearance.
  • Swap Sugary Drinks: Replace sugary drinks with water, herbal teas, or diluted fruit juice (no more than 150ml per day).
  • Choose Whole Foods: Prioritise whole foods like vegetables, fruits, and lean proteins, where sugars are naturally occurring and accompanied by fibre.

Conclusion: A Healthier, Less Sweet Future

Navigating the supermarket for healthy food in the UK can feel like a challenge, but understanding what are the hidden sugars in foods UK is the first and most powerful step. By learning to decipher food labels and recognising the marketing ploys used by manufacturers, consumers can reclaim control over their diets. This awareness can lead to simple, yet impactful, lifestyle changes that reduce the risks of obesity, type 2 diabetes, and other health issues associated with excessive sugar.

Yes, many savoury products like tomato-based pasta sauces, ketchup, salad dressings, and some tinned soups contain added sugar to balance acidity and enhance flavour.

The NHS recommends that free sugars should not make up more than 5% of your daily energy intake. For adults, this is approximately 30g (about 7 sugar cubes) per day.

When fat is removed from a food product, manufacturers often add sugar to maintain or improve the taste and texture. This is common in low-fat yogurts, dressings, and desserts.

Yes. While the sugar in whole fruits is not 'free,' once fruit is juiced or puréed, the sugar is released and counts towards your free sugar intake. This is why the NHS recommends limiting fruit juice to one 150ml glass per day.

The simplest way is to choose whole, unprocessed foods and cook more meals from scratch. When buying packaged goods, always read the ingredient list carefully and opt for plain or unsweetened versions where possible.
