Sensitivity notes
Why lectin food checker matters
Lectins are proteins found in many plant foods, especially legumes and grains. Some people follow low-lectin diets believing they reduce inflammation and digestive issues, though properly cooked foods have reduced lectin content.
- Proper cooking destroys most lectins - never eat raw beans
- Pressure cooking is highly effective at reducing lectins
- Peeling and deseeding reduces lectin content
- Fermentation can reduce lectins in some foods
- Sprouting may increase or decrease lectins depending on the food

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.
