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 oats
Oats are naturally gluten free, yet they carry two triggers people miss. First, cross-contact: most oats are grown and milled alongside wheat, so unless the box says gluten free they usually pick up gluten, and a minority of people also react to avenin, oat's own protein. Second, oats are high in nickel, which matters if you have systemic nickel allergy.
Watch for
- Naturally gluten free, but routinely cross-contaminated with wheat unless labelled gluten free (the grade C reflects this, not the grain itself)
- A small share of coeliacs also react to avenin, oat's own protein, even with certified gluten-free oats
- High in nickel (grade D), a common trigger for systemic nickel allergy and dyshidrotic eczema
- Rated poorly for SIBO, where the fermentable beta-glucan fibre can add to bloating
