Curtail your caffeine intake. While you may need that extra burst of energy in the morning, try and resist those second and third cups of coffee. Studies show that the extra caffeine can weaken your bones.
Take your vitamins. Supplementing your diet with a multivitamin is a good way to get the vitamins and minerals you may lack by eating too much junk food. Strong bodies (and overall joint health) will benefit from bone-building calcium and vitamin K, tissue-repairing vitamin C, pain-relieving vitamin E, folic acid and more.
