Grain-free bread is a type of bread that is made without any grains, including wheat, barley, rye, or corn. Instead, it is made from a combination of nutrient-dense ingredients like almond flour, coconut flour, and psyllium husk. The absence of grains makes grain-free bread an excellent alternative for those with gluten intolerance or celiac disease, as well as those who want to reduce their carbohydrate intake.
