(HealthDay News) -- It's important to practice good bone health when you're young, to prevent problems later in life.

The American Academy of Orthopaedic Surgeons offers these guidelines for people of different ages:

• Between ages 10 and 20: Get 1,300 milligrams of calcium each day by eating plenty of calcium-rich foods such as cheese and leafy green vegetables. Drink at least three 8-oz. glasses of milk each day.
• Between ages 20 and 35: Get at least 1,000 milligrams of calcium each day. Perform exercises such as jogging or walking to help strengthen bones.
• Between ages 35 and 50: You still need 1,000 milligrams of calcium each day as bone loss may have already begun. You may want to ask your doctor about bone density screenings.
• Age 50 and older: Be sure to get at least 1,000 milligrams of calcium each day, and at least 20 minutes of weight-bearing exercise three days a week or more. Also, your doctor may recommend a vitamin D supplement.
