Hemp has a unique fatty-acid profile that includes common omega-3 and -6 fatty acids, plus less common stearidonic (SDA) and gamma linoleic (GLA) acids. These fatty acids fight inflammation and protect your heart and immune system.
Hemp milk, rich in the above fatty acids, is a great source of protein and calcium — and tastes pretty good, too. Commercial varieties contain fillers and sweeteners, so you may wish to make your own by tossing hemp seeds and water in a blender and straining the mixture through cheesecloth.
Hemp makes a great vegan protein powder, high in fiber and lacking in fillers (it’s simply milled hemp seeds). While the powder is not a complete protein, it’s pretty close to perfect in my book.
