Tomato ketchup is a sweet, tangy condiment made from concentrated tomatoes, vinegar, sugar, and spices. It is a useful dietary source of lycopene — a carotenoid antioxidant found in cooked and processed tomatoes that is associated with reduced risk of certain cancers — as cooking and concentration increases lycopene bioavailability compared to fresh tomatoes. However, it is high in free sugars (~22g/100g) and sodium (~1.1g salt/100g) and should be used in moderation.
A tablespoon (17g) is a typical serving, providing around 20 kcal and 3.7g sugar. Reduced-sugar and reduced-salt versions are available and provide the lycopene benefit with a lower sugar and sodium load.

* % Daily Value is the proportion of an adult
EU Nutrient Reference Value (NRV) supplied by 100g of this food.
NRVs are the labelling standard — the same basis as the “%RI” figures printed on
food packaging — so these percentages are directly comparable with a shop label.
They are a single adult figure and do not vary by age or sex, which is why they
sometimes differ from UK dietary reference values: the NRV for vitamin C is 80mg
where the UK RNI is 40mg. When Nutriofia assesses your own intake in the
reports and trackers, it uses the age- and sex-specific UK values instead.
Fibre is shown without a percentage. Our fibre values use the UK
Englyst NSP method, while the published 30g daily goal is an AOAC figure — the two
are measured differently and a single percentage would mislead.
