What to know about ketchup
Ketchup is the textbook stacked trigger: no single ingredient in it is extreme, but it borders on a problem across an unusual number of them at once. It is made from concentrated tomatoes (nightshade plus histamine), cooked and aged (histamine and glutamate build up), sweetened with high-fructose syrup (excess fructose and FODMAPs) and often preserved with sulfites. Individually each is a moderate load; together, in the amount people actually use, they can push a sensitive person over the edge when a plain tomato would not. If you react to ketchup but tolerate fresh tomato, the processing is usually why.
Watch for
- Concentrated tomato makes it a nightshade and moderately high in histamine, two triggers in one spoonful
- Cooking and ageing raise free glutamate (a savoury, MSG-like load) and histamine beyond that of a fresh tomato
- Sweetened with high-fructose corn syrup, so it carries excess fructose and a moderate FODMAP load
- Often preserved with sulfites, a further additive trigger, and it is pro-inflammatory overall thanks to the sugar and processing
