Hi
@suekt139,
There are many other flours to choose from and it really depends on your personal likes and dislikes.
Possible substitutes are coconut flour, sunflower seed flour, lupine flour, soy flour. All of these are less than 10g of carbs per 100g. There is also linseed flour, which has almost no carbs, but should definitely only be used in combination with some other flours -- as I have found that the bread/rolls taste like cardboard if used in excess.
There also other nut flours such as macademia nut flour, hazelnut flour and walnut flour, but these tend to be a bit higher carb.
Personally, I always use a mix of flours when baking, trying to balance taste and carbs -- but it took some experimentation to get a feel for this.
Also remember that all of these flours don't contain gluten, so you always have to use something to increase the elasticity of the dough, so that it can trap the air while baking. For this, I use psyllium husks.
