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

Ingredient notes

What to know about fish sauce

Fish sauce is one of the highest-histamine ingredients in the kitchen. It is made by fermenting salted anchovies for months, and that slow breakdown of fish protein loads it with histamine and tyramine. On top of that it acts as a histamine liberator, nudging your body to release its own histamine, so even a splash in a stir-fry or dressing can trigger flushing, headache or a racing heart if you have histamine intolerance. It also carries moderate free glutamate, the umami compound behind its savory depth.

Watch for

  • Very high in histamine because it is aged fermented anchovy, a classic trigger for flushing, hives, headache or a stuffy nose
  • Doubles as a histamine liberator, so it can set off symptoms beyond its own histamine load
  • High in tyramine, which matters if you are on an MAOI or get tyramine-linked migraines
  • Moderate free glutamate gives the umami kick but can bother people sensitive to MSG-like additives
