Curly, Barb is exactly right. Whether the bread is low in carbs or not does not matter. You may find that many low carb products substitute things like corn flour (which we should not eat) to reduce the carbs. Instead, look for whole grains and no "enriched" flour. I believe Trader Joe's carries the Ezekiel bread, which is really good and is SBD friendly. I use their hamburger and hot dog rolls. Yummmm!
I envy you having a Trader Joe's nearby! I love their stores!
