Aldi Bramwells (82 kcal, 16.5g sugar, 0.9g salt per 100g) has the lowest sugar and calorie count of all UK supermarket ketchups and scored well for texture in the Which? 2024 blind taste test. ASDA Classic (106 kcal, 20g sugar) rated joint winner alongside Heinz in the same test, at 70% less cost. Heinz has the most sugar of all ketchups tested at 23.7g per 100g.

Sugar

Own-brand ketchup contains an average of 19.4g of sugar per 100g. All sugar in condiments is free sugar under NHS guidance — unlike the naturally occurring sugars in whole fruit or dairy, sauce sugar counts in full against the daily limit of 30g for adults, 24g for children aged 7 to 10, and 19g for children aged 4 to 6.

Compared to Heinz Tomato Ketchup (23.7g of sugar per 100g), most own-brand versions contain 4.3g less sugar. This is a meaningful reduction for regular use, particularly for children. Aldi and Lidl own-brand versions tend to have the lowest sugar content across most sauce categories.

Salt

Own-brand ketchup contains an average of 1.09g of salt per 100g. Small squeeze (10g) delivers 0.11g of salt, 2% of the adult daily limit. The salt content is broadly similar across supermarket own-brands and their branded equivalents, with most variation coming from spice blend differences rather than deliberate reformulation.

Value and nutritional difference

The cost difference between own-brand and branded condiments is significant. Supermarket own-brand ketchup typically costs 15-25p per 100g, compared to 55-70p per 100g for Heinz. Supermarket own-brand mayo costs 30-50p per 100g versus 60-80p for Hellmann's. The nutritional differences are marginal in most categories, making own-brand versions a practical choice for regular household use.

Aldi and Lidl consistently offer the lowest sugar and salt content across most sauce categories in this comparison, alongside the lowest prices. ASDA own-brand products have scored closest to their branded equivalents in independent taste tests (Which?, 2024).

Ultra-processed food

Own-brand condiments, like their branded equivalents, are classified as NOVA group 4, ultra-processed food. The ingredient lists are almost identical: the same functional additives (modified starch, xanthan gum, acidity regulators, colours) are used in both own-brand and branded versions to deliver consistent texture, flavour and shelf life at scale.

The main practical difference is that most supermarket own-brand brown sauces and sweet chilli sauces use spirit vinegar rather than barley malt vinegar, making them gluten-free — unlike HP Brown Sauce, which contains barley. This is relevant for coeliacs and those with barley sensitivity.
