Calcium and Vitamin D are two of the many natural compounds thought to improve health. Research suggests that in combination they could decrease colon cancer and improve bone strength. But recent clinical trials called both these attributes into question.
The Women’s Health Initiative monitored the bone and colon health of 36,000 post-menopausal women, half of whom received calcium and Vitamin D supplements. After seven years, no significant difference was observed between the women taking the supplements and those not.
But this doesn’t mean the case is closed--quite the contrary.
These studies leave a lot of unanswered questions. The amount of calcium and Vitamin D in the women’s diets was not controlled, and the benefit of calcium and Vitamin D may take a lifetime, not seven years.
So don't give up your milk and cookies, yogurt smoothies, and low fat ice cream. We all need some calcium and Vitamin D; science just needs to figure out how much.
This is Dr. Bruce Feinberg. Be well.
