Is farro gluten free?
No. Farro contains gluten: farro is a form of wheat, one of the grains FDA names as gluten sources (wheat, rye, barley and their hybrids).
What the gluten-free label means
A food labeled gluten free in the US must have less than 20 ppm gluten, whether the gluten comes from an ingredient or from contact during processing. Foods that are gluten free by nature, like fresh fruits and vegetables, can carry the label too (FDA).

Who needs to avoid gluten, and what going gluten free costs

- Level E NIDDK states that people with celiac disease need a gluten-free diet for life to prevent symptoms and intestinal damage from returning. NIDDK (NIH), Eating, Diet, & Nutrition for Celiac Disease
- Level C A meta-analysis of 40 studies found gluten above 20 mg/kg in 9.52% of labeled gluten-free products, against 28.32% of naturally gluten-free foods. Br J Nutr, 2022
- Level B Two granola bars a day carrying 10 g of gluten caused no more gut symptoms than gluten-free bars in 33 young people who felt better off gluten, difference on a 100 mm scale -0.01. Aliment Pharmacol Ther, 2022
- Level C Children who went gluten free after a celiac diagnosis had four times more arsenic in their urine six months later, because rice is what replaces wheat. American Journal of Gastroenterology, 2025
