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 port
Port is a fortified wine, and that single construction stacks more drink-related triggers into one small glass than anything else on this list. Grape spirit is added partway through fermentation, which kills the yeast, leaves a great deal of unfermented sugar behind and pushes the strength to around 20 per cent. Then the wine spends years in cask. The result grades D for histamine, D for sulfites, D for excess fructose and C for tyramine, so port is flagged on four separate axes at once, which almost nothing else in the drinks category is. Fortified and long-aged wines have a long-standing place on migraine trigger lists and on the tyramine restrictions given to people taking MAOI medication, and they are among the first things dropped on a histamine intolerance elimination diet. If you are asking why a small glass of port gives you a headache when a similar volume of spirits does not, the answer is that port is doing four things at once.
Watch for
- Histamine grades D.Fermentation generates biogenic amines and years in cask give them time to build, so a tawny that has sat in wood for a decade is not a low-histamine drink by any reading. Fortified wine is standard on histamine intolerance elimination lists
- Sulfites grade D.Wine is sulfited to protect it and a sweet, high-sugar wine generally needs more, which is why bottles carry a "contains sulfites" declaration. Flushing, a blocked nose or a wheeze within minutes of a small glass points here rather than at the alcohol
- Excess fructose D and FODMAPs D.Stopping fermentation early is the whole point of fortification, so the grape sugar that would have become alcohol stays in the glass. This is the difference between port and a dry red, which grades far lower on the sugar axis
- Tyramine grades C.Combined with the histamine load and the ageing, this is why fortified wines are named specifically in tyramine guidance for people on MAOIs, alongside aged cheese and cured meat
- At roughly 20 per cent alcohol, port delivers about half again as much ethanol per millilitre as table wine, so a pour that looks small is not a small dose
