First off, this bread is awful. I would rather eat a properly fermented sourdough bread made from a real cultured starter and from fresh, spouted, non-GMO wheat flour any day over a disgusting nut meal bread. When you bake nut meals, the omega 6 content oxidizes very easily (you ground it into a flour - that means surface area exposed to oxidation increased by an order of magnitude). Superheated omega 6 linoleic acid has an industrial term - varnish - which is essentially heated flaxseed oil. You're making industrial paint thinner in your oven whether you know it or not, and I'd rather eat a fermented wheat bread than this monstrosity. The only nut I'd consider baking with in significant quantity like this is macadamia meal, but it is very cost prohibitive and not exactly nutritious versus real food.
Second, the idea should be to get off not just wheat bread, but bread-like products as well. Replacing wheat flour brownies with the gluten-free blend at the grocery store isn't going to do a whole lot for your health. Anything ground up into a powder is going to not only destroy (and oxidize) some of the beneficial compounds in the food, but it's going to make it a whole lot easier for your body to digest. That means you're going to get hungry faster and eat more calories.
People shouldn't be trying to find a healthy replacement for bread. They should be trying to remove it. If you're going to have a treat, assuming you don't have some massive intolerance, just eat the real damn thing if you think it's worth it and avoid it the rest of the time. One splurge pizza dinner once a month is going to be a whole hell of a lot better for your health than your oxidized daily almond meal bread!
