Why paleo diet checker matters

Paleo affects how your body responds to certain foods. Understanding your personal tolerance helps you make informed choices.

  • Keep a detailed food and symptom diary to track your personal reactions
  • Eliminate the suspected trigger completely for 2-4 weeks
  • Reintroduce gradually to find your personal tolerance threshold
  • Work with a healthcare provider or registered dietitian for guidance
  • Remember that food sensitivities can change over time

Ingredient notes

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
