Sensitivity notes
Why vegetarian diet checker matters
A vegetarian diet excludes meat and fish but may include dairy products and eggs. It focuses on plant foods with optional animal-derived products like milk, cheese, and eggs.
- Eggs and dairy can help meet protein needs
- Include a variety of plant proteins for balanced nutrition
- Iron-rich foods pair well with vitamin C
- Don't rely too heavily on cheese as a protein source
- B12 is still important if limiting animal products

What to know about tomato sauce
Tomato sauce is one of the most concentrated food triggers in an ordinary kitchen. Simmering and reducing tomatoes stacks histamine, salicylates, oxalate, free glutamate and nightshade compounds into every spoonful. It grades high in histamine, so it is a frequent reason people flush, get a headache or a runny nose during an Italian meal, and it is also high in oxalate and a nightshade.
Watch for
- High in histamine, and reducing tomatoes down to a sauce pushes it higher, so marinara often bothers people more than a fresh raw tomato does
- High in salicylates and a moderate histamine liberator, a double hit if you are aspirin-sensitive or histamine-intolerant
- High in oxalate, which matters on a kidney-stone (calcium oxalate) diet
- A nightshade with high free glutamate, so it can flare both nightshade sensitivity and umami/glutamate reactions
