gluten-free eats

That's probably the case! I'd guess that cassava flour has less starch and probably more protein, though looking at Bob's nutritional information it has zero protein, and about the same amount of carbs as tapioca, which does not sound right.

Elsewhere on the internet it says cassava flour has 1.6 grams of protein per serving and 417 grams of sodium, and Bob says zero on that too. Then again, this site is defining a serving as 100 grams, and I don't know anyone eating that much cassava flour in one sitting. That's FIVE of my rubbery carrot muffins.
