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 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
