As Hip dysplasia is both genetic and environmental he may be predisposed to HD due to his genes. I don't think there is any food that can prevent it, only by choosing puppies whose sire and dam have low hip and elbow scores and growing your puppy slowly and limiting excessive exercise may reduce his/her chance.
My advice is to choose a good quality dry kibble, preferably fish based and give him some sort of joint and cartilage supplement. My female GSD has HD and I am managing her with Canidae grain free pure sea, raw meats and supplement her with human glucosamine and chondrotin capsules. She is doing fine, she clearly has not difficulty in moving, changing position and does not seem to be in pain. I have also tried canine products.
if your GSD is eating and eating and eating and losing weight - please consider testing for EPI.
