Osteoporosis is a disease of the bones which occurs when you lose too much bone, make too little bone or both. As a result, bones become weak and may break from a minor fall or, in serious cases, even from simple actions, like sneezing or bumping into furniture. Risk factors for osteoporosis include genetics, lack of exercise, lack of calcium and vitamin D, personal history of fracture as an adult, cigarette smoking, excessive alcohol consumption, history of rheumatoid arthritis, low body weight, and family history of osteoporosis. Nutrition and bone health are closely related. A healthy diet can help you prevent and manage osteoporosis by assisting in the production and maintenance of bone.
