Hey, Katy. I have some in my pantry that are 100% whole buckwheat flour. They’re a product of Japan – I picked them up in my international foods aisle at the grocery. The brand is Eden Selected and the package says Buckwheat Soba Noodles and also says 100% whole grain buckwheat. The ingredients are just whole grain buckwheat flour.
I haven’t tried them, yet, though. “Noodle” forms are generally higher on the glycemic index (for instance, brown rice pasta is through the GI roof!) and I’ve been a bit nervous about them. I’m saving them until my symptoms are further reduced, but I could just be being a big scaredy cat 😉
