Osteoporosis is a disease that affects white elderly women more than any other group, and can be treated according to Carol E. Goodman, MD. In her article "Osteoporosis: Protective Measures of Nutrition and Exercise," appearing in Geriatrics, April 1985, Dr. Goodman recommends the following for adequate protection and treatment: calcium --- 1,000 mg. Daily before menopause and 1,500 mg. Daily after menopause; vitamin D --- 400 IU daily for adults and 800 IU daily for the elderly; sunshine; good posture; back care precautions; exercise appropriate to the patient’s age and physical condition (walking is an excellent form), and avoidance of smoking
