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 carrageenan
Carrageenan is a thickener extracted from red seaweed (E407) that keeps plant milks from separating and gives ice cream, cream and deli meat their body. On the classic food chemistry triggers it is clean: no histamine, no salicylates, no FODMAPs, no lactose, gluten, nickel, sulfites or free glutamate, which is why it grades A across those columns here. Its D grade for inflammation and its exclusion from AIP come from somewhere else entirely: a long-running and genuinely unresolved argument about whether food-grade carrageenan irritates the gut lining. Understanding that argument is the difference between avoiding it for a reason and avoiding it out of noise.
Watch for
- Most of the alarming animal research used poligeenan, not carrageenan.Poligeenan is an acid-degraded, low molecular weight version (around 10 to 20 kDa) that is not permitted in food and is used deliberately in laboratories to induce inflammation and ulceration. Food-grade carrageenan is a much larger molecule. Anyone quoting the ulcer studies at you is usually quoting the wrong compound.
- The distinction is real but not perfectly clean.EFSA re-evaluated carrageenan in 2018, kept the group acceptable daily intake at 75 mg per kg of body weight, but made that figure temporary and asked for better data, noting that the low molecular weight tail of food-grade carrageenan overlaps with the high molecular weight tail of poligeenan.
- Human evidence is thin in both directions.A small randomised trial in ulcerative colitis patients in remission found earlier relapse in the carrageenan arm, but with roughly a dozen participants it is a signal to follow up, not a verdict. If you have IBD or react to plant milks specifically, it is a sensible single variable to test in a food journal.
- It is easy to remove from a diet without noticing what you removed.Carrageenan concentrates in plant milks, dairy-free cream and yoghurt, ice cream, processed cheese and sliced deli meat, and those products carry other candidate triggers too. Swap the product, then reintroduce, rather than assuming the additive was the culprit.
