I found a lower carb bread at the store yesterday from Silver Hills Bakery in British Columbia. It’s a smaller slice sprouted wheat bread and comes in at 19 g carb for 2 slices. For comparison, Dave’s Killer Bread (thin-slice, 21 seeds and grains) has 24 g carbs for 2 slices.
I really love good, artisanal style bread so these fall short on flavor for me. On the other hand, I don’t get much of a spike and it’s handy when the local baker doesn’t have rye bread on offer.
