Healthy bones are essential to a healthy life. Bones give you structure, help you move, protect your organs and store calcium. Bones deteriorate and break down as a natural part of life. By the age of 30 your bones are breaking down faster then they are being built. When women hit menopause this deteriorating process speeds up, because estrogen-the hormone that protects against bone loss-is no longer produced. Therefore women are at an increased risk of acquiring osteoporosis. Osteoporosis or "porous bone" is a disease of the skeletal system characterized by low bone mass and deterioration of bone tissue. Osteoporosis leads to an increased risk of bone fractures typically in the wrist, hip and spine (CDC 2007).
Bone mass is like a bank account--you only have as much as you put in. Calcium is the money in that account. The more calcium stored before age 30, the less likely you will develop osteoporosis. Good sources of calcium include: -Dairy products--low fat or nonfat milk, cheese and yogurt -Dark green leafy vegetables--broccoli, spinach and salads -Calcium fortified foods--orange juice, cereal, bread, soy and tofu products -Nuts--almonds The recommended amount of calcium each person should have is described in the table below. | Ages | Amount mg/day | | Birth–6 months | 210 | | 6 months–1 year | 270 | | 1–3 | 500 | | 4–8 | 800 | | 9–13 | 1300 | | 14–18 | 1300 | | 19–30 | 1000 | | 31–50 | 1000 | | 51–70 | 1200 | | 70 or older | 1200 | | Pregnant & Lactating | 1000 | | 14–18 | 1300 | | 19–50 | 1000 | Certain people are more susceptible to osteoporosis. These risk factors include those who are: -Female -White/Caucasian -Post menopausal women -Older adults -Small in body size -Eating a diet low in calcium -Physically inactive Consuming the right amount of calcium and participating in regular physical activity are protective factors against osteoporosis. The following are some examples of weight-bearing physical activity that provide positive health benefits including strong bones: -Walking, Jogging, or running -Tennis or Racquetball -Field Hockey -Stair climbing -Jumping rope -Basketball -Dancing -Hiking -Soccer -Weight lifting for additional information and resources check out the following: http://www.cdc.gov/nccdphp/dnpa/nutrition/nutrition_for_everyone/bonehealth/index.htm http://www.nof.org/osteoporosis/bonehealth.htm Centers for Disease Control and Prevention (CDC).
