Doctors have identified a new risk factor for heart disease, according to an article in the July issue of Preventive Medicine.

The Omega-3 Index measures the levels of the most heart-healthy omega-3 oils, gained mostly by eating fish or taking fish oil supplements.

Research has shown that an Omega-3 Index of 8 percent to 10 percent reduces a person's relative risk of death from coronary heart disease by 40 percent, and from sudden cardiac death by 90 percent.

However, lower levels of omega-3 oils in a person's body can increase the risk of heart disease, said researchers at St. Luke's Mid-America Heart Institute in Kansas City.

"We are designed to thrive on a diet high in omega-3 fatty acids, but most Americans eat far too little fish to reap any benefits from the omega-3 oils," lead researcher Dr. William Harris said in a prepared statement. "Even those who regularly eat fish or take fish oil supplements may not be getting enough for their unique, individual needs."
