The Full Answer
Granola's primary ingredient is oats, which are naturally gluten-free but almost always cross-contaminated with wheat, barley, or rye during processing. Up to 88% of commercial oats contain gluten above 20 ppm.
Beyond contaminated oats, many granola brands use barley malt syrup as a sweetener — a definite gluten source. Some granolas also contain wheat flour, wheat germ, or cookies/pretzels as mix-ins.
For safe granola, look for brands that specifically use certified gluten-free oats AND are labeled GF. Purely Elizabeth, Bakery on Main, and Nature's Path Organic all make certified GF granola options. Making your own granola with certified GF oats is the safest option.
