History and context
Gluten-free products moved from specialist pharmacy shelves into every supermarket in the 2010s, driven by a rising coeliac diagnosis rate (now 1 in 100) and a much larger wave of non-coeliac gluten-sensitivity self-identification. The category has professionalised, with independent certification bodies now setting a stricter ceiling (10-20 ppm) than the legal 'gluten-free' claim in most markets.
🐇 The animal-rights angle
Gluten-free itself is neutral on animal welfare, but many coeliac-focused shoppers pair it with a plant-based or vegan lens — both benefit from a compact whole-food staple list (naturally gluten-free grains, legumes, produce). Where you land depends on the values you stack on top of the medical necessity.
🌍 The sustainability angle
Some gluten-free grains (rice, corn) have significant water or emissions footprints; others (buckwheat, millet, sorghum, teff) are genuinely low-input crops well-suited to marginal soils. Diversifying your gluten-free staples away from rice-and-corn defaults is a small but meaningful sustainability lever.
