Calcium Does Not Reduce Osteoporosis?

Two large studies conducted by the Harvard School of Public Health showed that calcium doesn't actually reduce the risk of osteoporosis as we once thought.

However, the lifestyle measures listed below can also help prevent bone loss as we get older - after age 30 both men and women begin losing bone mass slowly; this accelerates for women after menopause:

  • Exercise regularly. Walking, jogging or anything else you can do on your feet and strength training for muscles.
  • We don't get much Vitamin D in our diets. Try to get regular sun exposure as our skin is able to manufacture the Vitamin D. Some gardening in the morning sun is good as you get exposed to sunlight and the bending and squatting will help to increase bone density.
  • Get adequate daily vitamin K. Low intake has been linked to low bone density. You get vitamin K in broccoli, Brussels sprouts, dark green lettuce, collard greens and kale.
  • Watch your protein intake. Too much can promote calcium loss from bones.
  • Preformed vitamin A (identified on vitamin labels as "retinol" or "vitamin A palmitate") can weaken bones.
  • Cut back on caffeine and sodas: too much of either can promote calcium excretion.
