Sprouts are best consumed raw. When you cook them, they will start to wilt and lose their crunchy texture. But more importantly, they will also lose most of their nutrients, as they are not heat stable. So if you are growing sprouts to add more nutrients to your diet, cooking or even blanching your sprouts is counterproductive. If you are growing your sprouts correctly, use the right equipment and use seeds that are safe for sprouting, then it is completely safe to consume raw sprouts.
