Lung Cancer Risk May Be Increased By Inorganic Phosphates in Processed Foods

Jan 14, 2009 by TacticularCancer.com

According to the Centers for Disease Control (CDC), lung cancer is the number one cause of cancer deaths worldwide. The American Thoracic Society points out that over 75 percent of lung cancers are non-small cell lung cancers (NSCLC) and have an average overall 5-year survival rate of only about 14 percent. Previous research has shown that about 90 percent of NSCLC appear to be activated by specific signaling pathways in lung tissue. The new study by Dr. Cho and his research team found that high amounts of dietary inorganic phosphates actually stimulate those same cancer-triggering pathways.

In a statement to the media, John Heffner, M.D., past president of the American Thoracic Society, pointed out that this kind of research in animals can reveal the complex interactions between host factors and the environment that can result in human cancer. “We know that only some patients who smoke develop lung cancer but the reasons for this varying risk are unknown. This study now provides a rationale for funding case-control studies in humans to determine the potential role of dietary phosphates in promoting cancer,” Dr. Heffner stated.

While living organisms need a moderate level of phosphate, the use of inorganic phosphates as a food additive to increase water retention and improve food texture artificially has soared over the past decade. That means the average American diet is loaded with excess amounts of phosphates. “In the 1990s, phosphorous-containing food additives contributed an estimated 470 mg per day to the average daily adult diet. However, phosphates are currently being added much more frequently to a large number of processed foods, including meats, cheeses, beverages, and bakery products. As a result, depending on individual food choices, phosphorous intake could be increased by as much as 1000 mg per day,” Dr. Cho explained in the media statement.

“The results of this study suggest that dietary regulation of inorganic phosphates has a place in lung cancer treatment, and our eventual goal is to collect sufficient information to accurately assess the risk of these phosphates,” he said.
