New research published in the 2006 Journal of the National Cancer Institute found that the more processed meat people eat, the higher their risk of developing certain types of cancer, such as colon, stomach, gastric and rectal.

While these studies have become more and more common in the mainstream press, according to the USDA Economic Research Service (ERS), Americans are buying more pre-processed meat products than ever before.

Processed and pre-processed meats include bacon, sausage, hot dogs, salami, ham and smoked or cured meat.

Consequently, the World Health Organization (WHO) reported in their 2003 World Cancer Report that cancer rates are set to increase by 50 percent to 15 million new cases in the year 2020.

According to the American Cancer Society, the salt, smoke residue, and nitrates and nitrites used as preservatives might play a role. Or it might have to do with the way the meat is cooked: high temperatures can create higher levels of cancer-causing substances in meats.

Lenka Schvaigeroba, 22, junior economics major from the Czech Republic, said she didn’t know that processed meat has been potentially linked to cancer. But she said processed meats, such as deli meat and cold cuts, taste good.

"If I read some study that showed huge risks, I might consider decreasing my consumption," Schvaigeroba said.

But she said it doesn't really concern her.

“Everyone knows smoking kills, but they still do,” she said.

But Angela Zare, 52, a graduate student in biochemistry who has been studying cancer, said differently. The Armenian native said she never buys processed food and she avoids dining out at American restaurants.

"I know what it does and I don't want to risk it," she said.

Dr. Randy Huffman, the vice president of scientific affairs for the American Meat Institute, said the sale of meat in general, processed or not, has remained relatively stable. However, the type of meats the consumer now demands has changed. Deli-meats and shaved meats have become particularly popular.

“There is a growing need for convenience,” Huffman said.

Huffman also questioned the studies in the popular press.

“The only thing consistent in the results is the inconsistencies,” Huffman said. “If you get caught up in the study of the month, you’ll drive yourself crazy.”

He stressed the importance for consumers to maintain a healthy weight, an active lifestyle and a balanced diet based on the U.S. Dietary Guidelines.

David Garland, junior art major said he was also unaware of the studies, but it wouldn’t deter him from eating meat.

“I know I don’t have control of my diet the way I would like to,” Garland said. “Ideally I would take a year long vacation to do nothing but fast and mediate and cleanse my system from all harmful products, but right now, I am in a pressure situation with school and responsibilities, so I eat what is convenient.”
