I think broth would be ideal, but it might seem like a lot of effort for you. It's actually not - once you do it once it's simple. I would get whole chicken joints (not just the bones) and bung them in a saucepan with water, veg of choice etc. Cook for five hours. Once it's done you can eat the meat with the broth - it will be nice and tender. You can always reuse the bones for another batch of bone broth.
I'd recommend paté but I haven't found a store bought one in the UK that doesn't have a heap of crap in it...

"I think the basic anti-aging diet is also the best diet for prevention and treatment of diabetes, scleroderma, and the various "connective tissue diseases." This would emphasize high protein, low unsaturated fats, low iron, and high antioxidant consumption, with a moderate or low starch consumption.
In practice, this means that a major part of the diet should be milk, cheese, eggs, shellfish, fruits and coconut oil, with vitamin E and salt as the safest supplements."
