Eating a diet high in protein and iron-rich foods, like the popular Atkins diet, might put some people at risk. A new study from the University of South Carolina warns that if you happen to be a person who does not store iron efficiently, a high protein diet could push you into a dangerous iron overload. Previous studies have linked high iron levels to cancer. It's estimated that 1 out of 10 people in this country are considered high iron storers. So be sure to talk to your doctor before jumping into a high protein diet because your doctor may want to give you a blood test to check your iron levels first.

Sounds great, but researchers want to continue more tests before making this available to heart patients.
