I'm on a collagen diet and I love it! I know that a collagen diet has anti-aging benefits and that's great. But I'm actually on it for arthritis and joint pain. I have to say that it has made a huge difference for me. My joint pain is almost totally gone and I'm much more active than I used to be. I could barely walk up the stairs before I started this diet.
I eat salmon at least twice a week and make my own chicken broth and use that to make meals.
