Serving size, prep, and portion notes for 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
