Flaxseeds are harder than sesame seeds, so it’s a good idea to grind them — coarse or fine, depending on the recipe. That way, too, all the nutrition in flaxseeds is more readily available to the body. Keep what you don’t use in the refrigerator or freezer, as the oils in flaxseeds, like those in most nuts and seeds, will oxidize if not kept cold. This substantial smoothie is perfect following a high-energy workout.
