3 Reasons You Need More Vitamin D in Your Diet

Tiger Woods won it in 2000, 2002 and 2008; Rory McIlroy won it in 2011; Jordan Spieth, in 2015. But what did these three have in common at this year’s U.S. Open? This triple threat didn’t even make the cut.

It’s tough to see a triple threat like these guys booted out of the Open, but some triple threats need to be kicked to the sidelines! And that’s what the mighty vitamin D may help do to breast cancer, colon cancer and diabetes.

A recent study from UC San Diego School of Medicine found that women over age 55 with higher levels of vitamin D—above 60ng/ml—had one fifth the risk of breast cancer as those with less than the recommended levels (20-50ng/ml).

Another study—the largest of its kind—from the American Cancer Society, the Harvard T.H. Chan School of Public Health and the National Cancer Institute, found that lower levels of vitamin D are linked to colorectal cancer risk. Below current guidelines, a 31 percent increase in risk of developing colorectal cancer; above the guidelines, a 22 percent reduction in risk.

Finally, a third study from UC San Diego School of Medicine and Seoul National University found people with blood levels of vitamin D above 30ng/ml had one-third of the risk of diabetes and those with levels above 50ng/ml had one-fifth the risk.

So, get a blood test to measure your vitamin D level, and if it’s low, ask your doc how to bring it up to 60ng/ml or better with diet and supplements.
