Sensitivity notes

Why histamine food checker matters

Histamine is a compound naturally present in many foods, especially aged, fermented, or preserved items. In sensitive individuals, excess histamine can cause headaches, flushing, hives, digestive issues, and other symptoms. Your body normally breaks down histamine, but some people have reduced capacity to do so.

  • Focus on fresh foods - histamine builds up as food ages
  • Cook and eat meals fresh; avoid leftovers sitting more than 24 hours
  • Be cautious with fermented foods, aged cheeses, and cured meats
  • Consider that stress and hormones can affect your histamine tolerance
  • Some antihistamines or DAO supplements may help (consult your doctor)

What to know about whey protein

Whey protein grades at the very top of the dairy protein scale (E), which surprises people who switched to it precisely to avoid dairy. Whey is one of the two proteins in milk, alongside casein, so a scoop is a concentrated dose of exactly the thing a cow milk protein allergy reacts to. Lactose is a separate and much smaller issue: it grades moderate (C), high enough to explain the bloating and wind that people blame on the protein itself. Everything else is quiet. Whey is clean on gluten, sulfites, nitrites, lectins, nightshades and every FODMAP other than lactose, and only borderline on histamine, tyramine and glutamates.

Watch for

  • Graded highest on dairy protein (E).If you or your child reacts to cow milk protein, whey is not a dairy alternative, it is dairy in its most concentrated form, and it must be declared as milk on the label.
  • Moderate lactose (C), and the amount depends entirely on the grade.Concentrate keeps a meaningful share of milk sugar, isolate is filtered down to very little, and hydrolysate less again.
  • The moderate FODMAP grade is essentially the lactose.Strip that out with an isolate and the FODMAP problem largely goes with it, but the protein does not change at all.
  • Borderline on histamine, histamine liberation, tyramine and glutamates.Low-level rather than a strong trigger, but enough to notice if you drink a shake alongside other borderline foods every day.
  • Vegetarian but not vegan, and not a fit for a paleo pattern.
