Calcium supplements and colon cancer
Calcium supplements may help prevent colon cancer
by: News Canada
Although it is relatively well-known that calcium is important to bone health, mounting
evidence reveals that this mineral can also play a role in reducing the
risk of colon cancer.
According to a study funded by the National Institutes of Health and the
National Colorectal Cancer Research Alliance, higher milk consumption and
calcium intake are associated with a lower risk of colorectal
cancer (colon cancer). More than half a million individuals participated in
the study that showed that increasing calcium intake to 1,000 mg/day
or more could result in 15% fewer cases of colorectal cancer in women
and 10% fewer cases in men. Colorectal cancer is the third
most common cancer worldwide.
A similar study published in the Journal of the National Cancer
Institute shows that calcium supplements can also lower the risk of large
bowel polyps and large colon polyps, which are pre-cursors to colon cancer.
Despite the evidence that shows calcium plays an important role in
promoting long-term health, Canadians are still not getting enough according to
nutrition surveys. It is recommended that those aged 19 to 50
years old consume at least 1,000 mg of calcium daily, and those over 50
consume 1,500 mg of calcium. To help meet daily calcium requirements,
one should consume foods/beverages rich in calcium such as milk, cheese,
yogurt and dark green leafy vegetables and consider taking a daily calcium
supplement like Caltrate Select, which contains added vitamin D to increase
calcium absorption.
