Sensitivity notes
Why oxalates food checker matters
Oxalates are compounds found in many plant foods that can bind with calcium to form crystals. High oxalate intake may contribute to kidney stones in susceptible individuals and can cause other symptoms in those with oxalate sensitivity.
- Stay well-hydrated to help prevent oxalate crystal formation
- Pair high-oxalate foods with calcium-rich foods to bind oxalates
- Cooking and boiling can reduce oxalate content in some foods
- Spread oxalate intake throughout the day rather than one large dose
- Consider probiotics - some gut bacteria break down oxalates

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.
