Eating processed meats could increase the risk for heart disease and diabetes.

A new study found that meats like hot dogs, bacon and deli meat pose the greatest risk.

Eating just two ounces per day increases the risk for heart problems by 42 percent and the risk of diabetes by 19 percent.

That may be due to the higher amount of salt and preservatives in those meats. But unprocessed meats like steak and hamburger do not seem to have the same risk.

"The study doesn't suggest that people should panic if they had a piece of processed meat for lunch or cut it out of their diet completely, but as people are making choices it may be better to move away a little bit from the processed meats," said Harlan Krumholz, professor of medicine and epidemiology at Yale University School of Medicine.

"It's about portion size and about eating sensibly," Krumholz added. "If people use prudence in looking at their meals, they're going to do fine."
