Short answer - yes, milling your own flour is worth it for many people! Maybe not for everyone. This question boils down to your values and nutritional preferences. If you are aiming to have the most nutrient-rich diet that you can, want to get more fiber in your day, minimize glucose spikes, love bread, and want to learn to bake wholesome, nutritious goodies, then you're going to love milling your own flour. But if you don't eat gluten or grains, eat very low levels of carbohydrates in a day, or if you simply don't have time to bake, then you may wish to focus your energy elsewhere.
